Abstract
a. Le moteur, à aimant permanent notamment, comporte un boîtier, des pièces polaires maintenues sur ce boîtier, et un rotor tournant entre ces pièces. b. On prévoit au moins deux coquilles ferromagnétiques de la longueur des pièces polaires, montées dans le boîtier en entourant complètement le rotor, leurs surfaces frontales opposées se trouvant à peu près au milieu des pièces polaires. c. Ces coquilles permettent de fixer les pôles avec une grande facilité ce qui diminue le coût de fabrication.
