Abstract

Moteur pas à pas, notamment pour une horloge électronique, comprenant un enroulement pour engendrer une force magnétique sous l'action d'un courant fourni par un circuit électronique prédéterminé, un stator pour transmettre ladite force magnétique et un rotor, qui peut tourner sous l'action de ladite force magnétique transmise par ledit stator. Selon l'invention, ce moteur est caractérisé en ce que ledit rotor est composé d'un aimant permanent cylindrique présentant six pôles magnétiques également répartis à la périphérie dudit rotor, ledit stator entourant le rotor comprenant deux paires de parties saillantes et une paire de parties évidées et lesdites parties saillantes et lesdites parties évidées étant respectivement symétriques par rapport à l'arbre dudit moteur. Moteur pas à pas, notamment pour horloge électronique.
