Abstract

L'invention concerne les moteurs pour les montres électroniques à affichage analogique. Un moteur électrique de montre comprend essentiellement un rotor 1, aimanté de façon permanente, qui est en couplage magnétique avec un stator 2, 3. Le stator est en couplage magnétique avec une bobine 5. On améliore le rendement du moteur en utilisant pour le stator une matière qui présente un BH max élevé, et en réduisant le rapport entre le rayon du rotor et celui du stator. Application à l'horlogerie.
