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.
