Split Phase

January 8, 2011 4:15 am | Electric Motors

why we need to split the phase of single phase motor.?

A single phase induction motor has zero starting torque. We split the phase to give it some torque at zero speed. once started it will run just fine. So the starting winding (the split phase) is normally switched off. (using a centrifugal switch)
