Question

Why does a single phase induction motor needs a capacitor to start ?

Answer 1

Answer:

Explanation:

Because there is no rotating stator magnetic field, a single phase induction motor has no starting torque. ... The idea behind capacitor start single phase motors is an extension of the split phase winding technique used to produce the starting torque in single phase induction motor.

Answer 2

Hi there!♥️

-> Single phase induction motor is not the self starting so, to make it self start we can use capacitor & capacitor also provides high starting torque.

Thank you ☺️
