Split Phase Permanently Connected Capacitor Electric Motor
This too has a squirrel-cage rotor with a main and starting winding. A capacitor is permanently connected in series with the auxiliary winding. A motor of this type starts and runs with a fixed value of capacitance in series with the starting winding.
The motor obtains its starting torgue from a rotating magnetic field produced by the two stator windings physically displaced. The main winding is connected directly across the line, while the auxiliary or starting winding is connected to the line through the capacitor, giving an electrical phase displacement.
This motor is good for direct connected drives requiring low starting torque such as fans, blowers, some pumps, etc.
