Abstract

Le moteur électrique comporte un stator présentant une pluralité de pôles dont les faces polaires sont espacées les unes des autres dans la direction de déplacement d'une armature mobile en matériau magnétique Au moins un bobinage est enroulé sur le stator et est agencé pour que, lorsqu'il est excité par un courant alternatif, les faces polaires aient même polarité et pour que la densité de flux des faces polaires varie de façon alternative, sans changement de polarité, de part et d'autre d'une valeur moyenne, afin d'induire le déplacement de l'armature par rapport au stator. Application à la construction de moteurs électriques à auto-démarrage à rendement élevé.
