Abstract
(EN)
The present invention relates to a magnetic gear type electric rotating machine. Specifically, the purpose is to provide a magnetic gear type electric rotating machine with which the intensity of a permanent magnetic field can be improved without increasing material and manufacturing costs, and deterioration of torque transmission characteristics can be prevented. To this end, in the present invention, concave and convex sections are provided on a surface of at least one of cores (12, 22) for a first permanent magnetic field (1) and a second permanent magnetic field (2). The convex sections (13) are arranged along the circumferential direction at the center sections of permanent magnetic poles (11a, 11b), and the concave sections (14) are arranged along the circumferential direction at the edge sections of the permanent magnetic poles (11a, 11b).

La présente invention concerne une machine tournante électrique du type à engrenage magnétique. Plus précisément, elle concerne une machine tournante électrique du type à engrenage magnétique au moyen de laquelle l'intensité d'un champ magnétique permanent peut être améliorée sans augmenter les coûts de matières et de fabrication, et la détérioration des caractéristiques de transmission de couple peut être empêchée. A cette fin, dans la présente invention, des sections concaves et convexes sont aménagées sur une surface d'au moins un des noyaux (12, 22) pour un premier champ magnétique permanent (1) et un deuxième champ magnétique permanent (2). Les sections convexes (13) sont disposées suivant la direction circonférentielle au niveau des sections centrales de pôles magnétiques permanents (11a, 11b), et les sections concaves (14) sont disposées suivant la direction circonférentielle au niveau des sections périphériques des pôles magnétiques permanents (11a, 11b).
