Why we use Capacitor in Single
Phase Induction Motor?

Answer Posted / karuna nidhan singh

we use capacitor in single phase induction motor because
here is only single phase so no any phase difference.To
revolve the motor we want phase difference (shift) is
necessary. so we use capacitor in single phase induction motor.
In order to generate sufficient rotating torque we have
split the phase in to two and so we can use it.
