To make the single phase induction motor self-starting, it is temporarily converted into two-phase motor during starting. For this purpose, the stator of a single phase motor is provided with extra winding known as starting winding in addition to the main winding. This is invariably done with a capacitor in series with the second winding.
- Motors with low starting torque have the capacitor left in circuit all the time
- Motors with higher starting torque might need a bigger capacitor, and that will have a centrifugal switch to disconnect it once the motor is running
Shaded pole motor is used to drive the devices which require low starting torque. It doesn’t have any centrifugal switch.
