The models of the transformers for the Distribution Aerial Networks – Classes 15 and 36.2 kV are single-phase and three-phase types, according to the need to attend to customers of the electricity distribution concessionaire.
In urban areas of medium, high and very high load densities will be installed three-phase transformers. In low-density urban areas and in rural areas, single-phase transformers can be used.
In order to be correctly defined before the installation of single-phase transformers, the existence of consumer units that require three-phase power must be evaluated, or if there is a medium-term increase in load.
With this analysis can be avoided the premature amplification of transformers, from single-phase to two-phase.
The single-phase transformer is the transformer which is supplied by a single phase alternating current system, or by a phase-neutral or phase-phase circuit derived from a polyphase circuit. This type of transformer is used for small consumers requiring a voltage of 127 V to 380 V.
The values assigned for the maximum equipment voltage in kV, nominal voltage and primary and secondary connection of the transformer can be observed.

The correct processes to make mechanical protections of the electric motors, can be classified as totally and explosion-proof drip and splash. Drip and splash proof is the engine with all parts rotating or under tension, protected against dripping water from all directions, not allowing the direct or indirect entry of drops or particles of liquids or solid objects that spill or the engine. 7600 OLB
We can conclude that motors must be protected for the protection of professional operators, in the same way as against harmful external influences, and must meet safety requirements. An important element, called the motor housing, is to fix it in the working environment, protecting it according to the environment in which it will be installed.
The carcass is made in such a way that it joins the different modalities of mechanical protection to meet the requirements of the norms of installations and machines for which the motors will need to be destined.
It should be noted that fully enclosed machines, there is no exchange of the refrigerant medium between the outer environment and the interior of the enclosure. Depending on the characteristics requested, the motors may or may not have fans for cooling.
Synchronous generators are responsible for practically all electrical energy used in the world and in general, the composition of the generators depends on the type of machine. Synchronous generators have:
– Stator – The casing is of calendered steel and the package with its respective winding plates are on its ribs;
– Rotor – Accommodates the field winding, whose poles are made up of bundles of plates.
– Main exciter stator and rotor and rotating rectifier diodes.
– Auxiliary exciter and auxiliary coil;
– Nameplate – Contains the data with the nominal characteristics of the generator.
– Paint: background paint, applied by immersion and final paint, finished after the complete assembly of the machine, it is a varnish coat of synthetic enamel applied with a gun. X718-3A-30M
In relation to the synchronous generators, we can emphasize some characteristics for understanding: the synchronous machine is an electrical equipment, with double excitation, where in the armature or armature (usually the stator) circulate alternating balanced currents, forming a rotating field, that is, lagged currents in time travel spatially lagged coils.
The inductor or field is excited by direct current, forming an electromagnet. The two fields must rotate at the same speed so that a nonzero mean torque is obtained.
It is worth mentioning the fact that DC motors are components whose main objective is to convert the mechanical energy into electrical energy, such as generator, or electrical energy in mechanics, motor. In today’s world, alternating voltage electronic devices are already able to control the speed of the asynchronous motor in an easy way and for its reduced cost and application features, they end up replacing the DC motors in most applications. It can be said that nowadays, the alternating current is the form of electric energy used in the distribution and the locomotion of the same.
The motor capable of operating from direct current consists of a commutator ring, stator, rotor and brushes. The rotor element is of great value, since it consists of the rotating part, composed on the axis of the machine, which is formed by a ferromagnetic element wrapped in the armature winding and switch ring. The commutator ring has the function of reversing the direction of the currents passing through the armature winding. The stator consists of the static part of the machine, mounted around the rotor. And the brushes consist of pieces of graphite that are responsible for driving energy into the rotor circuit.
The disk-shaped windings may involve a single bundle or several bundles of interlaced and isolated conductors in a series-parallel orientation of interconnected horizontal discs. Each disc contains several turns, one on top of the other, with alternating intersections between interior and exterior.
The life of a transformer is related to its insulation system, its insulation material and the process of producing the material. The characteristics of the insulation system depend on the conductor geometry, the dielectric composition, temperature gradients and the characteristics of all the combined materials that have been applied. LOR400SAP44
Most transformers with this type of winding belong to the voltage class of 25 kV, and are usually of the core type involved. Given the high voltages studied in the tests and their operation, we must pay special attention to prevent high mechanical stresses between the disks and the ends of all the turns when subjecting the equipment to transient voltage peaks. Several techniques have been developed to support an allowable voltage distribution throughout manufacturing under these conditions.
The insulating system of the electric motors focuses on the joining of several different insulating materials applied to the electrical components. This arrangement in an electric motor takes place through wire insulation enamel, impregnation varnish and resin, groove closure insulation, insulation between phases, groove bottom, bonding cable insulation and weld insulation .
However, components that do not spontaneously come in contact with the coil are not part of the insulation system and the properties of a product of any thermal class, we can not guarantee that each insulating material applied in its construction has the same capacity or class thermal.
The specification of an element belonging to a certain thermal class does not necessarily mean that each insulation material applied in its composition has the same thermal capacity. It should be remembered that the temperature limit for an insulation system should never be directly related to the thermal capacity of the materials used. It is good to verify that in any system, the thermal performance of an element can be optimized by the protective properties of certain materials used together with that material.
The power needs to be supplied by the electric motor at the shaft end is more diminished than the power the motor can absorb from the power line, so the motor efficiency will always be less than 100%.
In closed motors, this dissipation is assisted by the fan installed on the motor shaft itself. A practical dissipation may be modified, depending on the strength of the ventilation system of the total dissipation area of the housing, of the temperature difference between the outer surface of the housing and the ambient air. 2100-5M-15 Gates
The main difference between the two powers is the heat losses, which automatically heat the winding and dissolve into the external environment of the engine, with the main function of preventing the increase in temperature from being considered excessive. The same fact can happen in all other types of engines.
In the case of a car engine, the heat generated by the internal losses will be taken from the block through the water circulation system with the radiator or by the fan in the case of air cooled engines. The heat generated by the losses inside an enclosed motor is wasted into the ambient air through the outer surface of the housing.
Induction in the air gap is strictly proportional to the remaining induction and the surface of the magnet. The first defined dimension is the height of the magnet, which will then be the entire length of the rotor, with a clearance of 2.05 mm at the end. The second dimension of the magnet will be the thickness that should be determined so that the maximum current that can be presented by the converter will not demagnetize the magnets in the rotor.
Since the remaining induction is a property of the magnet, attention is focused on the size of the magnet. In the buried magnets, special care must be taken to prevent the flow from flowing and proceed from the north pole to the south pole without passing through the engine air gap. An axis in non-ferromagnetic material will be fundamental.
An alternative to be checked is the application of a ferromagnetic axis enveloped by a layer of non-ferromagnetic material, as this option reduces the cost of the shaft, however it increases the cost of manufacture, as it increases the number of assembly elements. In order to minimize the dispersed flow, the magnets lie against the non-ferromagnetic axis, so there is no path in the center of the rotor for the flow to disperse.
Among the elements applied for impregnation is the silicone resin, which is generally only used in the case of specific machines designed for very high temperatures. The varnishes and resins improve the thermal and electrical characteristics of the materials used, being attributed to them, a thermal class superior to the impregnated materials, compared to the same materials without impregnation.
Two types of varnishes and two types of impregnating resins, all of which are based on polyester, are normally used to fill all possible constructive and application needs of the engines. The impregnation varnishes and resins have as main objective to conserve together all the enamelled wires that are in the coil with all the components of the stator and filling the voids within the groove.
It is important to remember that the connection of the wires has the capacity to prevent them from vibrating and striking each other. Friction can cause wire enamel to fail, resulting in a short circuit. Removal of the voids helps in the thermal dissipation of the heat caused by the driver and, especially in applications of motors fed by frequency inverters, can avoid or even reduce the partial discharges, known as corona effect, that occurs in the engine.
It should be remembered that at an average temperature of 40 ° C, the life of a continuously running ball bearing can be three to four years or in some cases even longer. In the case of motors with a small footprint, the initial lubrication in the assembly is designed to ensure a high number of hours of operation.
It may happen that the grease reserve is sufficient for the entire life of the equipment and in large engines there will be a need for more lubrication. SD14005 OVP
The frequency of lubrication changes in the design of the bearings and the properties of the lubricants used. For every 10 ° C of working temperature rise the working life decreases automatically. The lubrication of bearings, in addition to ensuring a more efficient performance, has the function of avoiding the elevation of the temperature that can interfere and reduce the durability of these equipments. Lubrication of bearings is usually done with mineral grease.
As soon as the operating temperatures are high or the speeds of rotation increase from 1,500 rpm, we must use mineral oil to perform the lubrication. These oils must have lubricating properties adapted to the working conditions.
The philosopher Aristotle understood that the concept of force based on philosophy, as an important complementary part of Aristotelian cosmology. In the point of view of the scholar, who is still very popular today, nature has essentially four elements: fire, earth, air and water.
He linked matter to earth and gravity as the tendency of objects to seek their natural place, and in this way the natural movement was distinguished from forced movement, which gave rise to the concept of force. Aristotle knew this question, and in this way suggested that the air displaced by the projectile could provide all the necessary force so that its movement could continue. The paradox revolved around the fact that the force was applied to the projectile only at the beginning of the flight, since the projectile was in the air just after the initial impulse. H29000
Some other additional questions in the Aristotelian model were generated by the lack of due treatment in relation to the air resistance of the projectile movement. This theory, based on tests of moving objects such as carts, for example, did not uncover the behavior of projectiles, such as flying arrows.
It is important to note that if the electric motors are individually packed, they should never be lifted by the axle or its packaging, but with the appropriate devices and lifting eyebolts, if they exist.
The devices called lifting eyebolts are designed in such a way that they can support only the weight of the motor, which is specified on the nameplate. The use of hoisting eyes is not recommended to perform the suspension of the engine along with other equipment, such as bases, pulleys, fans, pumps and reducers, among others.
In case the eye bolts are compromised, as for example with possible cracks or deformations, they should never be put into use. It is of the utmost importance that, in addition to all the safety measures that must be taken, all conditions must be checked before using them. Boston Gear 9F 1-3/4
Lifting eyes in components such as forced ventilation lids and kits or other devices should only be used to independently lift the same components and never to the complete engine. The motors that are supplied on pallets need to be suspended in the correct way, ie by the base of the pallet. Under no circumstances should the packaging be turned.
An electric DC motor is an electric machine that receives AC power, also known as AC, whereas this power can be supplied from a battery or other DC power source. The energy exchange between the stator and the rotor is called switching and can happen by means of or without brushes. In a DC motor, the speed can be controlled quietly only by changing its voltage, unlike an alternating current electric motor, Heavy Duty Retractable Hose Reel which has its speed pointed to by the frequency.
Therefore, AC electric motors need a change in their frequency in case you need to vary their speed, thus involving a much more complicated speed control. However, by changing the speed on an electric DC motor, it will only need to change the voltage level, making it more suitable for 12Vdc-powered equipment, such as cars or even industrial applications that need a fine speed control.
Induction electric motors have almost intermittent speed and low-power induction motors are mostly single-phase, short-rotor motors and starters require special devices since they do not have their own starters. It features changeable speed.
In the motor to the repulsion the winding of the rotor is taken to the brushes that are interconnected in short circuit and presents variable speed, being thus it is applied quite often like engine of repulsion induction. At start it operates as a repulsion motor and has its own start and, later, a centrifugal device, where the slides of the collector are short-circuited, starting to work as a single-phase induction motor reelcraft S24-260044.
The three-phase induction motors are high-power and self-starting. Since they require a large network current, at their starting point, special devices are applied to reduce it. In series or universal single-phase motors the rotor winding is fed to the brushes through a switch (collector formed by separate blades) and connected to the stator. This type of motor operates on both direct and alternating current.
The well-planned ventilation system, in addition to having an efficient fan capable of moving a large mass of air, must conduct this air in order to sweep the entire surface of the housing where the heat exchange takes place. The displacement of a large volume of air would not help if it spreads without removing the heat from the engine. In order to analyze whether or not motors can work in these environments, the size and quantity of the fibers contained in the environment must be reported to the manufacturer.
These factors are important because a large amount of dust deposited on the motor fins can act as a thermal insulation, and larger fibers can cause over time, clogging the ventilation, damaging the cooling system, leading to burning the engine 7800 OMP. When the fiber content is high, air filters or engine cleaning should be used, as well as carefully cleaning the ventilation holes, cleaning the fins, removing dust and fibrous materials, ensuring that the engine installation site guarantees free movement of air, check the operation of the auxiliary ventilation system and free circulation of air in the ventilation ducts.
The combination of elements with insulating properties, usually used in electrical components, is called an insulation system. This important junction that occurs in electric motors is a number of factors, such as groove closure insulation, insulation between phases, wire insulation enamel, groove bottom, varnish or impregnation resin, insulation of the connecting cable and soldering. Liquid materials, solids and gases can be used in the insulation of electrical equipment, varying according to the needs of the system. Components whose main function is insulation are automatically responsible for limiting, directing and even preventing the flow of electrical currents.
However, even if it is one of the main purposes of the insulation material, acting in the impedance of the current flow of a conductor to earth or even a reduced potential, it can still offer a specific mechanical support, in this way, preserving the conductor dc speed dart of any degradation that may be caused by external factors and pass external heat into the environment. Insulation systems are able to interfere with the quality of equipment as well as insulation, directly influencing the weight, cost, performance and durability of your system.
It should be noted that the foundation, as well as an application, refers to the structural element, in the prepared or natural base, which is properly designed to support the efforts generated by the installed equipment, thus enabling the operation of these with high security, stability and performance. In this way, the foundations design needs to take into account the adjacent structures, so that it can avoid the influence of one piece of equipment on the other, to ensure that the propagation of vibrations does not occur. The stresses generated at the time of operation by the driven load need to be considered as an important part of the foundations dimensioning. In this way, the user becomes completely responsible for all the project, preparation and, finally, the execution of the foundation.
arm control magpowr
That is, the foundation must be flat and its detailing and execution requires specifications, such as the construction of the equipment itself, involving not only the values and the way in which the loads will act, for which purposes and maximum limits of compatible deformations and vibrations in each specific case. It is necessary to consider the neighboring constructions, allowing the understanding of the state of conservation, the estimation of the maximum loads applied, type of foundation and fixation employed and vibration levels transmitted by these constructions.
It is important to stress that a significant loss of power in the transfer of the same, which may be the result of numerous factors, such as wire resistance and currents through the nucleus, known as eddy current, for example. Thus, a transformer is composed of at least two independent windings, although they suffer the action of the electromagnetic field, which is more intense, in relation to the transformers that have a core of ferromagnetic material. The winding in which the voltage to be transformed is applied is called the primary winding and the winding which achieves the desired secondary voltage.
Transformers, which can also be called detraphos EJMM3710T-5, refer to electrical elements that are intended to insulate a circuit, to increase or reduce a voltage. These elements are also used to cause the necessary impedance between different circuits or as part of filters in radio frequency circuits. Transformers of many types can be found, each of which has a different purpose, construction and size. It can be stated that a transformer needs to transfer all the power from the primary to the secondary, remembering that the primary and the secondary consist of the input and output windings, respectively.
It is important to emphasize that the technicians responsible for all the operation and maintenance of the electrical processes often analyze the power factor of a load as one of the indicators responsible for affecting the transmission and efficient generation of electric energy. It is a common practice to perform the correction of the power factor to an approximate value to the unit. This action is called power factor correction, and is usually obtained according to the coupling of banks of inductors or capacitors, with a reactive power Q, unlike that of the load, resulting in the component cancellation. For example, the inductive effect of different machines Gates 9274-4280 can be canceled from the parallel connection of a capacitor, or bank, to the equipment.
In case the load has a considerably lower power factor than one, automatically more current will be required in order to supply the same amount of useful power. The companies that supply electric energy establish that consumers, especially those with larger loads, keep the power factors of their electrical installations within a minimum limit. The power capacity must be increased to 0.96, or consumers may be charged extra.
In permanent capacitor motors, the auxiliary winding, like the capacitor, is permanently energized, considering that the capacitor is always of the electrostatic type. The function of this capacitor is to enable adequate flow conditions to be considered very similar to those found in multi-phase electric motors, thereby increasing maximum torque, efficiency and power factor, thus having the ability to reduce noise significantly. For example, blowers, office machines, fans, exhaust fans, centrifugal pumps, grinders, small saws, drills, air conditioners and sprayers, among other equipment can be mentioned.
Considering the constructive factor, this type of motor 101218LF has a smaller size and is normally free of the need for periodic maintenance, since they do not use contacts and moving parts, as in other types of engines found. However, its starting torque is lower than that of the split-phase motor, which can vary between 50% and 100% of the nominal torque, a factor that may be decisive in case it is necessary to limit its application to equipment that does not normally require high starting torque.
The purpose of lubrication in electric motors is to reduce friction and internal wear and prevent overheating. The grease serves as a vehicle for the added oil, which does the lubricating functions.
The most frequent failure is not the lack of lubrication, but the excessive lubrication, made with a larger amount of grease than recommended.
Excessive lubrication raises the temperature, due to the great resistance that occurs in the movement of the rotating parts and mainly due to the grease beat, which ends up completely losing its lubrication characteristics.
This can cause leakage and penetrates the grease inside the engine and depositing it on the coils or other parts of the engine. The grease used in the motors 1125-5-100-A is polyurea grease specially developed for electric motor bearings.
This grease has good compatibility with conventional lithium greases, but it is not recommended to mix greases, and if you use another type of grease, consult the manufacturer.
For motors with shielded type bearings there is no need for relubrication since they have been factory lubricated for their normal life and use polyurea grease.
For the determination of the series equivalent impedance of transformers, the short-circuit test is used and the same procedure will be applied to the autotransformers, with some small differences.
Determining the serial impedance of a three-terminal autotransformer, primary, secondary, and tertiary, is more common than that of only two windings. When an autotransformer does not have a tertiary winding, the test is done in the same way as in the conventional transformer.
best roller bearings
As the equipment has three windings, three “binary” tests, ie a short test between the primary and the secondary with the tertiary open, a test between the primary and the tertiary with the secondary open and a test Between the secondary and the tertiary, with the primary open.
For the conventional transformer it is not possible to determine the value of the impedances of each of the separate windings by the short-circuit test, and so we find that Z1 = 2Z ‘= 0.5 Zeq, however, in the autotransformer test Possible to generate the impedance of each of the windings separately.
The thermal protector consists of a bimetallic disc, which contains two moving contacts, plus a resistance and a pair of fixed contacts. The protector is driven in series and due to thermal dissipation, which is generated by the passage of the current, through the internal resistance, a deformation of the disc can occur, resulting in the opening of the contacts and thus causing the motor power to stop .
After a lower than specified temperature has been reached, this protector must be reconnected. Depending on this process, two types of protectors can be used, one with automatic reclosing and the other with manual reclosing. These protectors are basically bimetallic type devices which have normally closed contacts, used mainly in single-phase induction motors, in order to protect against overheating caused by overloads, causing the rotor locking and voltage drops.
The thermal protector is applicable to electric motors GLP3348 of the three-phase type, but only to Y-connected motors. The advantages are a combination of current and temperature-sensitive protector. The drawback is the current limitation by the protector being directly connected to the single-phase motor coil.
In 1820, the Danish scientist Hans Christian Oersted did not imagine that with a simple experiment he would discover a physical principle of extreme importance for the operation of this type of motor. In this way, the scientist passed an electric current, produced by a normal heap, by a conductor wire and soon after approaching a compass of that wire. The needle, which acts magnetically, moved and aligned perpendicular to the thread. For Oersted, the event confirmed that around the wire, had a magnetic field, which acted on the field of the needle.
Thus, the relationship between magnetism and electricity was first established. The French physicist André-Marie Ampere, a genius of mathematics, after knowing the experiences of the Dane, began to create a law of electromagnetism, understanding that the lines of force created by the electrified wire, the magnetic field, are circular, that is, Form a kind of invisible cylinder around the driver. T2535173S
Up until now, the magnetic field had been thought to move only in a straight line, as from one magnet to another. In the connection between electricity and magnetism, there was Englishman Michael Faraday. He valued experience as evidence of natural phenomena. It was thanks to his experiences and his curiosity, he was able to demonstrate in 1822 the circular magnetic field.
The rotor of the electric motor needs a torque to start its rotation. This torque is usually produced by magnetic forces developed between the magnetic rotor poles and those of the stator.
Forces of attraction or repulsion, developed between stator and rotor, ‘pull’ or ‘push’ the rotor’s movable poles, producing torques, which cause the rotor to rotate faster and faster, until the frictions or loads attached to the shaft reduce the Torque to the value ‘zero’. After this point, the rotor rotates with a constant angular velocity.
At least some of the ‘magnets’ of a motor must be ‘electromagnets’. An engine can not run if it is built exclusively with permanent magnets, because not only will there not be the initial torque to ‘trigger’ the movement.
A simple electric motor consists of a coil that rotates between two permanent magnets. The magnetic poles of the coil (represented by the magnet) are attracted by the opposing poles of the fixed magnets. The coil rotates to take these magnetic poles as close as possible to each other, but when it reaches that position the current direction is reversed and now the poles that face repel each other, continuing to propel the rotor.
The magnetic motors of electric motors (stators and rotors), with few exceptions, are currently manufactured, based on thin metal blades (low carbon steel plates) with a thickness of less than 1 mm, assembled in sheet metal packages.
Some higher performance motors are made from silicon steel sheets, with about 3% silicon. The total process for the elaboration of these nuclei consists basically in lamination, packaging, stamping, a treatment for electrical insulation and fixation.
With respect to low carbon steel plates, the process for insulation is based on a heat treatment, where the plate packs are inserted in ovens for a certain time, and then the surface oxidation of the plates exists, and as a result, the formation Of an insulating layer of iron oxide between the joint sheets.
08B-2 10FT MORSE
Some types of silicon steel sheets are offered by manufacturers with a paint based oxide on one of the surfaces. Magnetic cores enveloped by coils (windings), where they travel alternating currents, form an alternating magnetic flux.
For this reason, these nuclei are exposed to the action of parasitic currents, also called Foucault currents, which are responsible for significant loss of power in these nuclei.

The purpose of maintaining an electric motor is to maximize the life of the equipment, thus avoiding unwanted stops.
Services performed on electric motors rab fxled78sf must only be carried out by trained personnel using only suitable tools and methods and must be arranged to stop the equipment and disconnect it from the mains, including accessories.
Several times during maintenance, it is necessary to transport the motors with roller bearings or angular contact, for this the shaft locking devices supplied with the motor must be used.
General inspections are part of the maintenance, and their frequency will depend on the type of engine, application and installation site conditions. It is recommended to visually inspect the engine and coupling, checking for noise levels, vibration, alignment, signs of wear, oxidation and damaged parts and replace them when necessary. Proper lubrication is of paramount importance. The proper functioning of the engine and to this must be used the type and amount of grease or oil specified by the manufacturer and follow the recommended relubrication intervals for the bearings. This information can be found on each motor nameplate.
The electric motor has two types of voltage: single-phase and three-phase. The single-phase voltage is measured between the neutral phase. The single-phase electric motor is connected in the normal way and is prepared to be connected in a network of 127 V or 220 V. However, there are still places where the single-phase voltage can be applied both at 115 V, and in 230 V and 254 V. in these cases, one must be applied to a specific electric motor for these tensions.
The phase voltage is also measured between the phases. It is the electric motor more used, because the single-phase electric motor has limited power and also provides income and torques that are smaller and this increases the cost of operation. In Brazil, the most commonly used three-phase voltages are 220V, 380V and 440V.

An induction motor is a type of electric motor built in such a way that it has two rotating magnetic fields, induction motors are electric machines, manufactured with only a few machines that use concrete engine that are called asynchronous machines, and these machines have asynchronous motor. See more at https://www.mrosupply.com/popular_products/baldor-general-purpose-motors/
Many motors and generators use three-phase electric power, an electric induction motor is basically composed of two parts, the stator and the rotor, we will explain how this type of induction motor, it is located in the space between the stator and the rotor is called air gap, the stator is the static part of the engine and the rotor of the movable motor.
The stator is made of thin sheets of magnetic steel and are heat treated and still have silicon steel to minimize the eddy current losses and hysteresis.
These plates have a ring shape with internal splines in such a way that they can be accommodated which in turn, when in operation, will create a magnetic field.
The most expensive electric motor that has the market today are the dc motors that because it takes several devices that convert alternating current into direct current, the investment is very high and so it is necessary to make a basic account to see You pay to have this type of engine in a machine, noting that energy expenditure is also high. JML1510T
As for the AC motors are cheaper and more widely used, because the electricity is distributed in the form of alternating electric current, thereby reducing their cost, these engines are found in many household usage equipment such as fan, mixer, blender, among others.
Below classify in a simple manner a comparison between the two types of engines.
DC: chain in which it has continuous flow of electrons and orderly in the same direction. AC: is a current whose magnitude and direction vary, there is variation of electrical current during operation, unlike direct current. .
