Abstract

L'invention se rapporte à un petit moteur électrique synchrone, à rotor à aimant permanent, qui est conçu pour être utilisé par exemple dans des appareils électroménagers tels qu'un réfrigérateur/congélateur, afin d'entraîner une ailette de ventilateur. Le rotor du moteur est pourvu de deux paires de pôles magnétiques désaxées, placées chacune dans un entrefer à l'intérieur d'un circuit magnétique simple. Un embrayage est également prévu pour que l'ailette du ventilateur puisse par exemple être montée sur le rotor et pour que le moteur puisse effectuer un démarrage fiable, dans la bonne direction, et accélérer à une cadence relativement lente jusqu'à atteindre la vitesse synchrone. Dans d'autres modes de réalisation, ledit moteur comprend des stators ayant deux ou trois paires de pôles magnétiques. Le procédé de construction du circuit magnétique desdits stators assure une utilisation efficace du matériau des stators.
