Dans un stator se composant d'un aimant permanent semblable à une toupie situé dans un logement annulaire composé d'une substance ferromagnétique, l'aimant permanent semblable à une toupie présente une structure telle que les mêmes polarités sont adjacentes les unes aux autres et des caractéristiques de pôle d'excitation telles qu'elles permettent d'améliorer la densité de flux magnétique et d'émettre un flux magnétique vers une armature à l'intérieur. L'armature composée d'une substance magnétique annulaire de l'armature et/ou d'une bobine d'armature est disposée sur la surface intérieure de l'aimant permanent semblable à une toupie et un arbre rotatif pénétrant à travers le centre de l'armature est également installé. L'invention concerne en outre un circuit de commande qui fournit un courant de commande à la bobine d'armature, ce qui amène le courant de commande à circuler dans une direction conforme aux polarités excitées de l'aimant permanent semblable à une toupie.
