Abstract

L'invention a trait à un moteur pas à pas monophasé. Chaque pôle auxiliaire du rotor d'un tel moteur se compose d'un prolongement s'étendant dans le sens circonférentiel dans la région marginale du rotor et le circuit magnétique permanent se compose d'au moins un aimant permanent, situé extérieurement à la circonférence du rotor, son axe polaire étant tangent au rotor. Une partie des lignes de champ magnétique se rejoignent dans la zone marginale périphérique d'un pôle principal et d'un pôle auxiliaire rotoriques. Application : miniaturisation de moteurs pour montres électriques.
