Abstract

La présente invention concerne un moteur électrique à bobinage de type à bague de démarrage à rotation horaire et antihoraire, comprenant un moteur électrique à induction à bobinage de type à bague de démarrage à rotation horaire et antihoraire, et un moteur électrique à hystérésis à bobinage de type à bague de démarrage à rotation horaire et antihoraire. La présente invention comprend un stator, un rotor, un composant de support, une coque, un mécanisme de commande et d'autres pièces, et est caractérisée en ce que les enroulements d'induit de chaque phase sont des bobinages qui sont disposés le long d'une culasse en segments. Un courant alternatif monophasé est introduit à l'aide d'un procédé de rotation horaire et antihoraire de bague de démarrage ; les flux magnétiques de culasse adjacents dans la même direction sont connectés les uns aux autres en série, et les flux magnétiques de culasse adjacents dans des directions différentes se rassemblent ; les flux magnétiques de culasse rassemblés forment des flux magnétiques de dent au niveau des dents les plus proches, et les variations des flux magnétiques de dent traversent différentes bagues de démarrage pour former un champ magnétique de stator rotatif qui tourne dans le sens antihoraire et dans le sens horaire à des vitesses multiples, entraînant ainsi le rotor à fonctionner à des vitesses de rotation nominales multiples.
