Magnet holder for a claw pole rotor
暂无分享,去创建一个
A rotor embodiment has sixteen magnets (11), each of which fits between two of sixteen claw-like magnetic poles (15, 16) formed on the outer periphery of Lundell-type pole cores (7) which rotate integrally with a shaft (6). The magnets are held in position by a magnet holder (12) which has been formed by interconnecting zig-zagging segments and has elasticity as a whole. Here, the permanent magnets are held by the magnet holder so that the magnet holder does not protrude towards the rotor side from the outer peripheral face of the Lundell-type pole cores and the contacting faces of the magnet holder contact the outer faces of the permanent magnets. The claw-like magnetic poles are disposed so as to face the stator (2).
