Abstract

L'invention a trait à un moteur pas à pas monophasé. Elle a pour objet de réduire la consommation d'énergie et d'améliorer le rendement et l'encombrement d'un tel moteur en réalisant les pâles principaux et auxiliaires associés à une partie de stator sous la forme d'un ensemble unitaire en tôle avec cette partie de stator. Application : notamment aux montres électriques.
