A PSC/PSC motor for 2-pole operation and 4-pole operation. The motor uses an independent 2-pole main winding and an independent 4-pole main winding. An auxiliary winding includes an independent 2-pole auxiliary winding, an independent 4-pole auxiliary winding, and a shared auxiliary winding used in both the 2-pole operation and the 4-pole operation.

2 speed 2/4-pole PSC/PSC motor with independent main windings and shared auxiliary winding

A PSC motor includes a stator core, a rotor arranged in a rotation relationship with respect to the stator core, a first to eighth winding coil sets wound around the stator core and a capacitor. The motor has two kinds of configurations for 4-pole and 6-pole operation modes, respectively. Both configurations comprise a primary winding and a secondary winding which is connected in series with the capacitor, and have two reversible operation directions. The configurations operate different sets of winding coils when operating in different directions.
