Double Revolving Field Theory of a Single Phase Induction Motor

Double Revolving Field Theory : In double revolving field theory of single phase I.M. basically states that a stationary pulsating magnetic field can be resolved into two rotating magnetic fields, each of equal magnitude but rotating in opposite directions. The induction motor respond to each magnetic field separately, and the net torque in the motor is equal to the sum …

How to starts induction motor

Starting Method of Induction Motor : When we connect the supply to the stator winding of a 3-phase induction motor, a rotating magnetic field is produced and the rotor starts rotating. Thus a 3-phase I.M. is self-starting. A 3-phase supply given to the armature of I.M. produces a rotating magnetic field. This rotating magnetic field links to the rotor coils …
