Abstract

La présente invention concerne un module multipolaire monophasé et un moteur à réluctance commutée combiné ayant un module multipolaire monophasé, appartenant au domaine des moteurs à réluctance commutée. Le moteur comprend un noyau de fer de rotor (20), un carter de moteur (30) et un arbre de moteur (40), et comprend en outre plusieurs modules multipolaires monophasés (10). À mesure que le moteur à réluctance est formé par combinaison de modules multipolaires monophasés (10) selon la présente invention, des phases n'ont pas de pôles saillants décalés entre eux ni ne partagent un circuit magnétique de culasse, et chaque phase n'utilise que le circuit magnétique de pôle saillant de ladite phase elle-même dans le processus de travail, ce qui permet de réduire l'inductance mutuelle entre les phases ; en même temps, par comparaison avec un noyau de fer intégré, l'utilisation d'un module multipolaire monophasé peut réduire de manière significative le coût d'un moule, en résolvant les problèmes d'induction mutuelle entre les phases et de coût du moule.
