Abstract
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.
