Abstract

L'invention porte sur un moteur de machine à laver, et sur une machine à laver possédant ce moteur. Ledit moteur comprend: un stator qui crée un champ magnétique rotatif; un pilote qui commande le stator, et un rotor en cage d'écureuil et un rotor magnétique mis en rotation par le champ magnétique rotatif créé par le stator. La machine à laver ne nécessite pas de stator à deux enroulements pour entraîner le moteur de lavage et le moteur de séchage, deux pilotes entraînant individuellement le moteur de lavage et le moteur de séchage, ce qui permet de réduire le coûts de production. De plus, l'utilisation d'un moteur à induction à la place d'un moteur BLDC coûteux permet également de réduire les coûts de production.
