Question

Which motors are called self-starting motors?

(a) single phase

(b) two phase

(c) three phase

(d) four phase

I got this question in a job interview.

I would like to ask this question from Polyphase System topic in section Polyphase Circuits of Network Theory

Answer 1

The correct option is (c) three phase

The best I can explain: Three phase motors are more easily started than single phase motors. Three phase motors are called self-starting motors. Single phase or two phase or four phase motors are not called self-starting motors.
