Abstract

L'invention concerne un moteur monophasé pas à pas. Dans ce moteur chaque face polaire rotorique a une structure asymétrique, de manière que, lorsque le rotor est au repos, la partie principale d'un pôle rotorique se trouve au voisinage d'un pôle statorique et une partie marginale au voisinage du pôle statorique suivant. Application en particulier à la fabrication de montres, par exemple de montres ou horloges à quartz.
