A 4/6 pole PSC motor having main and auxiliary winding configurations. Common windings are energized in both a 4-pole configuration and energized in a 6-pole configuration for both the main and the auxiliary winding configurations. An additional winding is energized in the 4-pole configuration only. As a result, the air-gap flux level of the 4-pole configuration can be varied substantially independent of the air-gap flux level of the 6-pole configuration by varying the configuration of the additional winding.
