Title:
VEHICULAR ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/067962
Kind Code:
A1
Abstract:
Provided is a high-output vehicular rotating electric machine which has a simple manufacturing process and can suppress the increase in magnetic sound that accompanies increase in output by reducing distortion in gap magnetic flux density. A permanent magnet (13) is arranged between claw-shaped magnetic poles (11A, 11B) which are adjacent to each other in the circumferential direction. A surface of the permanent magnet (13) faces the claw-shaped magnetic poles, and the area of said surface at the front side in the rotational direction is smaller than the area at the rear side in the rotational direction. It is therefore possible to increase output from a low-speed rotation area, reduce distortion in gap magnetic flux density, and suppress the increase in magnetic sound that accompanies increase in output.
