The three phase induction motor is an alternating current motor which is driven by the electromagnetic torque generated by the interaction between the rotating magnetic field formed by the stater winding and the magnetic field of the induced current in the rotor winding. it belongs to a kind of induction motor.
Magnetic contactor
Magnetic contactro are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from on and off state. magnetic contactor act as a safeguard to protect the power supply and the motor.
