It is noteworthy that most AC motors count on average with two elements considered as main and essential, consisting basically of a stator and a rotor. The stator refers to a slotted metal ring that holds the coils of insulated wire in a steel core. The alternating current passes through the entire length of these wires in order to produce a rotating magnetic field.
It can be stated that one of the main differences between the electric motor of alternating current and the electric motor of direct current, besides the power supply, consists of the form of control of the speed, that varies according to the tension applied and this relation can be linear, making speed control and calculations more simplified.
In this way, electric motors of alternating current are devices that have their power in alternating current. Electric motors are used in the conversion of electrical energy into mechanical energy, with the main mission of producing work in a system. The AC motor is used in the production of power for a wide variety of systems, ranging from small servomechanisms to large industrial machines.
