Answer:
A single speed permanent split capacitor AC induction motor has two separate pairs of series wound stator windings arranged at right angles to each other around the central rotor. The main run winding is connected directly to the AC power source while the secondary start winding is connected to the same source with a capacitor in series with it. The capacitor causes an electrical phase shift to the power in the start winding relative to the run winding, to produce a rotating magnetic field around the rotor which can start it turning. Since the capacitor remains in the circuit while the motor is running it's called a permanent split capacitor design.
