The net torque developed by a single-phase induction motor at starting is: Correct Answer Zero

In the case of single-phase induction motors we have only one winding (main winding). Due to which we have a pulsating magnetic field which first increases to a maximum value then become zero after that increase in the negative cycle to get maximum then become Zero.

It became zero twice in a cycle, so net torque produced is zero. Hence the torque developed by a single-phase motor at starting is zero. That by single-phase induction motor are not self-started.
