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.
