Why induction motor is called asynchronous motor?

Answer 1

as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torque. so since the rotor runs with a speed other than the synchronous speed of rotating magnetic field produced by stator current so it is called as asynchronous motor..

asynchronous -means not moving with synchronous speed

Answer 3

The word induction means that there is no contact between two parts. A current in the stator of the motor induces a current into the coils of the rotor of the motor. The induced current in the rotor produces a magnetic field that locks on to the revolving magnetic fields in the stator. The fact that it is a three phase motor means that this action is going on in the motor in three different places at once. The separation of this action is taking place 120 degrees from each other throughout each revolution of the stator field.
