The present invention resides in a capacitor-start, single-phase induction motor wherein connections for all coil windings are used during start-up and running of the motor. The induction motor during start-up is connected as a 2 pole motor and is switched to connect as a 4 pole motor when the capacitor drops out of the motor circuit. A cylindrical air gap motor with radial coils in a wound stator makes the pole change easily possible. The use of radial coils provides a design with a minimum of copper wire. This particular induction motor will reduce the use of copper wire in the wound coils by approximately 50%.
