The number of poles on starting winding of single phase induction motor are

The number of poles on starting winding of single phase induction motor are:

1. Same as on main winding
2. More than those on main winding
3. Lesser than those on main winding
4. Any of above

Correct answer: 1. Same as on main winding

Explanation: In a single phase induction motor, the stator carrier the main winding that creates a set of N-S pole. It also carrier a smaller starting winding that operates only during the time when motor starts up. The starting winding comprises of same number of poles as the main winding has.
