Question

what is the principle of electric motor​

Answer 1

Answer:

Explanation:

The principle of electric motor is when a current carrying conductor is placed in a magnetic field it experiences a force. ... These windings generate rotating magnetic field. Now the rotor conductor is subjected to varying magnetic field and emf is induced in the conductor and which leads to flow of current.

Answer 2

The field winding generates a constant dc flux. The armature conductor which carries current experiences force and the direction of this force is given by Fleming's left hand rule. Thus the motor starts rotating. The 3 phase induction motor works on the principle of induction
