Title
(EN) A SELF-STARTING BRUSHLESS ELECTRIC MOTOR
(FR) MOTEUR ELECTRIQUE SANS BALAIS A DEMARRAGE AUTOMATIQUE
Abstract
(EN)
A self-starting brushless electric motor having a first motor part (stator) (11) with poles arranged in a row, said poles constituting ferromagnetic poles (13S) or permament-magnet poles (14A), a second motor part (rotor) (12) with poles arranged in a row, said poles consisting of ferromagnetic poles (16A) or permanent-magnet poles and being arranged opposite the row of poles on the first motor part (11), wherein the motor part with salient ferromagnetic poles or, if both motor parts have salient ferromagnetic poles, at least one of the motor parts has a permanent-magnet pole, and also a magnetizing winding on the first motor part. The system of poles formed by the pole rows is magnetically asymmetrical in the direction in which the motor parts (11, 12) are movable in relation to each other.
(FR)
Moteur électrique sans balais à démarrage automatique possédant une première partie (stator) (11) comportant des pôles disposés en rangée, lesdits pôles constituant des pôles ferromagnétiques (13S) ou des pôles à aimant permanent (14A) et une deuxième partie (rotor) (12) comportant des pôles disposés en rangée, lesdits pôles consistant en des pôles ferromagnétiques (16A) ou en des pôles à aimant permanent et étant situées en face de la rangée de pôles de la première partie du moteur (11). La partie du moteur qui possède des pôles ferromagnétiques saillants, ou, si les deux parties du moteur possèdent des pôles ferromagnétiques saillants, au moins une desdites parties, possède également un pôle à aimant permanent, ainsi qu'un enroulement d'aimantation se trouvant sur la première partie du moteur. Le système de pôles constitué par les rangées de pôles est magnétiquement asymétrique dans le sens de déplacement des parties du moteur (11, 12) l'une par rapport à l'autre.
