Title (EN) ROTOR FOR ELECTRIC MACHINE
(FR) ROTOR POUR MACHINE ÉLECTRIQUE
Abstract: front page image
(EN)A rotor (10) for a rotary electric machine has a plurality of magnetic poles (24) provided at intervals, in a circumferential direction, at the outer periphery of a rotor core, (12). Each of the magnetic poles (24) has a first permanent, magnet (26) buried in the center of the magnetic pole, and a pair of second permanent magnets (28) that are buried on both sides of the first permanent magnet (26) in the circumferential direction, and that are disposed such that a mutual spacing between the pair of the second permanent magnets (28) becomes narrower inward in the radial direction. A narrowest spacing between the pair of second permanent magnets (28) is set to be wider than a longitudinal-direction width of the first permanent magnet (26) in a magnetic path region (30) that is defined by the first permanent magnet (26) and the pair of second permanent magnets (28).
(FR)L'invention porte sur un rotor (10) pour une machine électrique tournante, lequel rotor (10) comprend une pluralité de pôles magnétiques (24) disposés à intervalles dans une direction circonférentielle, à la périphérie extérieure du noyau (12) du rotor. Chacun des pôles magnétiques (24) comprend un premier aimant permanent (26) noyé dans le centre du pôle magnétique, et une paire de seconds aimants permanents (28) qui sont noyés des deux côtés du premier aimant permanent (26) dans la direction circonférentielle et qui sont disposés de sorte qu'un espacement mutuel entre les deux seconds aimants permanents (28) se rétrécisse vers l'intérieur dans la direction radiale. L'espacement le plus étroit entre les deux seconds aimants permanents (28) est défini pour être plus large que la largeur du premier aimant permanent (26), dans la direction longitudinale, dans une région de flux magnétique (30) qui est définie par le premier aimant permanent (26) et par les deux seconds aimants permanents (28).
