Abstract

Moteur pas à pas pour une pendule électronique. Selon l'invention, ce moteur est caractérisé en ce que le rotor est formé par un aimant permanent cylindrique présentant six pôles magnétiques également répartis autour dudit cylindre, le stator ayant une paire de parties en creux et une paire de parties saillantes dont la largeur est deux fois plus grande que celle d'une autre paire de portions saillantes, lesdites portions saillantes et lesdites portions en creux étant deux à deux symétriques par rapport à l'arbre du rotor. Pendule électronique.
