The starting torque of a 1-phase induction motor is

The starting torque of a 1-phase induction motor is

(A) High.
(B) Moderate.
(C) Low.
(D) Zero

Explanatory answer:

The single-phase I.M motor starting torque is zero because of the pulsating single-phase magnetic flux. The starting of the motor requires the generation of a rotating magnetic flux similar to the rotating flux in a three-phase motor.
