Abstract

L'invention concerne un moteur électrique pas à pas comportant un rotor et un stator alignés sur un axe commun. L'un des deux éléments constitué par le rotor et le stator porte deux paires de dents polaires intercalées, orientées perpendiculairement à l'axe, espacées axialement l'une de l'autre de manière que les dents polaires intérieures soient espacées radialement et circonférentiellement des dents polaires extérieures. Deux enroulements sont associés aux deux paires de dents afin de les aimanter sous des polarités opposées lorsqu'ils sont excités. Le second élément comporte plusieurs aimants permanents espacés circonférentiellement les uns des autres et disposés axialement entre les deux paires de dents polaires. Domaine d'application : moteurs pas à pas.
