Abstract: front page image
(EN)A plurality of salient poles (19) projecting toward a stator (12) are arranged on a rotor core (16) along the circumferential direction while spaced apart from each other, and rotor windings (18n, 18s) are wound around these salient poles (19). The rotor windings (18n, 18s) are short-circuited through diodes (21n, 21s), respectively; and when currents rectified by the diodes (21n, 21s) flow through the rotor windings (18n, 18s), the salient poles (19) are magnetized to produce a magnet where the magnetic pole is fixed. The width ϑ of each salient pole (19) in the circumferential direction is smaller than a width corresponding to 180° electrical angle of the rotor (14), and the rotor windings (18n, 18s) are wound around each salient pole (19) by short-pitch winding.
(FR)Une pluralité de pôles saillants (19) faisant saillie vers un stator (12) sont disposés sur un noyau de rotor (16) le long de la direction circonférentielle, tout en étant espacés les uns des autres, et des enroulements de rotor (18n, 18s) sont enroulés autour de ces pôles saillants (19). Les enroulements de rotor (18n, 18s) sont court-circuités par l'intermédiaire de diodes (21n, 21s), respectivement, et lorsque les courants redressés par les diodes (21n, 21s) circulent à travers les enroulements de rotor (18n, 18s), les pôles saillants (19) sont magnétisés de manière à créer un aimant, là où le pôle magnétique est fixe. La largeur ϑ de chaque pôle saillant (19) dans la direction circonférentielle est plus petite que la largeur qui correspond à un angle électrique de 180° du rotor (14), et les enroulements de rotor (18n, 18s) sont enroulés autour de chaque pôle saillant (19) avec un enroulement à pas court.
(JA) ロータコア(16)には、ステータ(12)へ向けて突出した複数の突極(19)が周方向に沿って互いに間隔をおいて配列されており、ロータ巻線(18n,18s)がこれらの突極(19)に巻装されている。各ロータ巻線(18n,18s)は各ダイオード(21n,21s)を介して短絡されており、各ダイオード(21n,21s)で整流された電流が各ロータ巻線(18n,18s)に流れることで、各突極(19)が磁化して磁極の固定された磁石が発生する。周方向に関する各突極(19)の幅θはロータ(14)の電気角で180°に相当する幅よりも短く、ロータ巻線(18n,18s)は各突極(19)に短節巻で巻装されている。
