What is an Electric AC/DC Motor?

Any electric motor with alternating current or AC as the power supply is called an electric AC motor. A typical AC motor comprises of two parts, namely, the stator which is stationary and a rotor. The stator consists of coils which are connected to an AC power source and produce a rotating magnetic field. The rotor is attached to an output shaft and generates another rotating magnetic field. Permanent magnets, DC or AC electrical windings or reluctance saliency are used to generate this magnetic field. The poles of the two magnetic fields are pushed or pulled along with their respective field speeds to maintain synchronism for produce torque. In AC motors, the alternating current is supplied to the stator which creates a rotating magnetic field. This moves the rotor that is connected with an output shaft.

Companies that are known for manufacturing AC or DC electric motors like Teco Electric Co. Ltd. have two types of AC motors which are classified as synchronous and induction. The synchronous motor uses permanent magnets, a rotor winding that is independently excited, and magnetic poles. This electric AC motor generates a torque at a synchronous speed. One of these synchronous motors is a brushless wound rotor that works accurately at the supply frequency. The induction or asynchronous motor bases its performance on the speed difference between the stator and rotor rotating magnetic fields. This means that the induction motor is not able to produce a torque about synchronous speed where there is no induction.

AC/DC electric motors are machines which are found in most common applications. Whatever kind of small or large appliances are taken into account, either of these motors will be seen. This reason is why electric motors are so important in household appliances as well as industrial ones. Clocks, pumps, drill machines, timers, fans and compressors are also some of the uses of AC motors.
