Answer Posted / p.prabhakar
Normally the motors works on the principle of Faraday's law and Lenz's law.There are two types of motors namely DC and AC motors.
In DC motors,the stationery part carring manetic flux is called field and the rotating part is called armature.when the current passes through the field and armature,a rotating driven force(called torque) is acting on the armature.Due to this the motor rotates.
Here the given supply is AC. Commutator is a device which converts AC to DC.In AC motor,commutator is not required and field is replaced by the name stator and armature by rotor.
