Title (EN) MOTOR
(FR) MOTEUR
(JA) モータ
Abstract:
(EN) A motor that includes a stator having windings and a rotor that is subjected to a rotating magnetic field generated by supplying driving current to the windings. The windings include serially connected first windings and second windings, and the first windings and second windings are excited simultaneously by the driving current. The rotor includes a multiple rotor parts arranged side by side in the axial direction. Each of the multiple rotor parts includes magnetic poles having permanent magnets, and magnetic flux permitting parts. In a rotational position of the rotor in which the magnetic poles oppose the first windings, the magnetic flux permitting parts oppose the second windings, and permit the generation of an interlinkage magnetic flux due to a weak field current in the second windings. The multiple rotor parts have the same number of magnetic poles, and the positions of the magnetic poles of the multiple rotor parts are offset with respect to each other in the circumferential direction.
(FR) La présente invention concerne un moteur qui comprend un stator portant des enroulements et un rotor qui est soumis à un champ magnétique tournant généré par fourniture d'un courant d'excitation aux enroulements. Les enroulements comprennent des premiers enroulements et des seconds enroulements connectés en série, et les premiers enroulements et les seconds enroulements sont excités simultanément par le courant d'excitation. Le rotor comprend de multiples parties de rotor disposées côte à côte dans la direction axiale. Chacune des multiples parties de rotor comprend des pôles magnétiques à aimants permanents, et des parties permettant un flux magnétique. Dans une position de rotation du rotor dans laquelle les pôles magnétiques sont en regard des premiers enroulements, les parties permettant un flux magnétique sont en regard des seconds enroulements et permettent la génération d'un flux magnétique d'interconnexion en résultat d'un faible courant d'excitation dans les seconds enroulements. Les multiples parties de rotor ont le même nombre de pôles magnétiques, et les positions des pôles magnétiques des multiples parties de rotor sont décalées les unes par rapport aux autres dans la direction circonférentielle.
(JA) モータは、巻線を有するステータと、巻線に駆動電流が供給されることで生じる回転磁界を受けて回転するロータと、を含む。巻線は、直列接続された第1の巻線と第2の巻線とを含み、第1の巻線及び第2の巻線は駆動電流によって互いに同一のタイミングで励磁される。ロータは、軸方向に並設された複数のロータ部を含む。複数のロータ部の各々は、永久磁石を有する磁石磁極と、磁束許容部と、を含む。磁束許容部は、磁石磁極が第1の巻線と対向するロータの回転位置で第2の巻線と対向し、第2の巻線での弱め界磁電流による鎖交磁束の発生を許容する。複数のロータ部の磁石磁極の数は互いに同数であって、複数のロータ部の磁石磁極の位置が周方向に互いにずれている。
