Title:
PERMANENT-MAGNET ROTATING ELECTRICAL MACHINE
Document Type and Number:
Japanese Patent JP2012016189
Kind Code:
A
Abstract:

To provide a permanent-magnet rotating electrical machine capable of decreasing a maximum value of a line voltage without decreasing a torque constant.

A protrusion part 31 protruding over a prescribed section in a circumferential direction is formed at magnetic poles 23A and 23B in an outer peripheral part of a rotor 20. Assuming that θ1 is a rotor magnetic pole open angle and θ2 is a protrusion part open angle centering around a magnetic pole center P, the protrusion part 31 is formed so as to satisfy (4/9)θ1<θ2<(2/3)θ1 in electrical degrees.
