Abstract
A stator in a synchronous fan includes first and second main windings, and an auxiliary winding. Illustratively, the first and second main windings are wound in a bifilar arrangement. In addition, the stator has a switch to switch the stator between a plurality of configurations. One of those configurations is an induction configuration that permits the first main winding to induce a voltage in the auxiliary winding when a current (e.g., a time-varying current) is transmitted through the first main winding. Moreover, the first main winding is electrically isolated from the auxiliary winding when in the induction configuration.
