Induction motors and commutators
WebOne type is called Squirrel cage motor and the other is called wound rotor induction motor (WRIM). The rotor of the squirrel cage motor has no winding, and there is no need for the rotor to be electrically connected to any electricity. The rotor of the latter, however, as the name implies, has windings. The induction motor is a type of AC asynchronous motor that works on the principle of electromagnetic induction between the stator & the rotor. The revolving magnetic flux induces a current in the rotor due to electromagnetic induction which produces torque in the rotor. Meer weergeven The AC electric motor converts AC (Alternating Current) electrical energy into mechanical energy. These electric motors are powered … Meer weergeven The DC motor is another main type of electrical motor that only runs on DC or Direct Current. There are no phases in direct current that is why DC electric motors only uses 2 wires to run.
