Title:
回転電機およびその製造方法
Document Type and Number:
Japanese Patent JP3977319
Kind Code:
B2
Abstract:
In an electric rotating machine, a rotor can be manufactured relatively easily at reasonable cost without high working accuracy for pole cores, and a permanent magnet can be assembled without impairing cooling efficiency of the rotor. A magnet-holding member 7 is separately fixed to a claw-shaped magnetic pole 21 of at least one of a pair of pole cores 2, 3 ; each magnet-holding member 7 is provided with a magnet mounting part 72 on which a permanent magnet 5 is mounted on two sides of the claw-shaped magnetic pole 21 in circumferential direction; and each magnet mounting part 72 is formed so as to be located between the claw-shaped magnetic poles 21, 31 engaged with each other.
