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.
L'invention concerne un stator situé dans un ventilateur synchronisé comprenant un premier enroulement principal et un second enroulement principal, ainsi qu'un enroulement auxiliaire. Le premier enroulement principal et le second enroulement principal sont enroulés dans un dispositif bifilaire. En outre, le stator comporte un commutateur permettant de commuter le stator entre une pluralité de configurations. Une de ces configurations est une configuration d'induction permettant au premier enroulement principal d'induire une tension dans l'enroulement auxiliaire lorsqu'un courant (par exemple, un courant variant dans le temps) est transmis à travers le premier enroulement principal. En outre, le premier enroulement principal est électriquement isolé de l'enroulement auxiliaire lorsqu'il est dans la configuration d'induction.
