When we apply a single-phase AC supply to the stator winding of a induction motor, it produces its flux of magnitude, φm. ... So, the single-phase induction motor is not self-starting motor.
Why single induction motors are not self-starting?
Single phase induction motor has distributed stator winding and a squirrel-cage rotor. When fed from a single-phase supply, its stator winding produces a flux ( or field ) which is only alternating i.e. one which alternates along one space axis only. ... That is why a single phase motor is not self-starting.
How are single-phase induction motors self-starting?
As explained above, single phase induction motor is not self-starting. To make it self-starting, it can be temporarily converted into a two-phase motor while starting. ... Hence, stator of a single phase motor has two windings: (i) Main winding and (ii) Starting winding (auxillary winding).
