Document Type and Number:
WIPO Patent Application WO/2013/001557
Kind Code:
A1
Abstract:
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).
