Answer Posted / raghunandan
as single phase Ac induction motor are not self starting
they need capacitor to introduce phase difference.In
capacitor start and capacitor run motor(all ceiling fans) by
interchanging the leads of either capacitor or running
winding we can change the direction of rotation.
