摘要： The present invention prevents the degradation of the power generating efficiency of an alternating current generator by preventing the expansion of an air gap formed between pole cores and a stator core, achieves low-noise operation by preventing generation of high-frequency impact magnetic noise, and makes it possible to relieve strains applied on a magnet holder. The present invention utilizes sixteen magnets, each of which fits between two of sixteen claw-like magnetic poles formed on the outer periphery of Lundell-type pole cores, which rotates integrally with a shaft. The magnets are caught and stopped by a magnet holder 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.
摘要翻译：本发明通过防止极芯和定子铁心之间形成的气隙的膨胀来防止交流发电机的发电效率的劣化，通过防止高频冲击磁性噪声的产生而实现低噪声运行，以及使得可以减轻施加在磁体保持器上的应变。本发明使用十六个磁体，每个磁体装配在形成在与轴一体旋转的隆德尔型磁极芯的外周上的十六个爪形磁极中的两个之间。磁体通过由相互之间的锯齿状部分形成并具有整体弹性而形成的磁体保持架而被卡住和停止。这里，永磁体被磁体保持器保持，使得磁体保持器不会从Lundell型磁极芯的外周面向转子侧突出，并且磁体保持器的接触面与永磁体的外表面接触磁铁。爪状磁极配置成与定子相对。
