摘要： PROBLEM TO BE SOLVED: To provide a highly reliable AC generator for a vehicle, which can achieve high output while suppressing the occurrence of eddy voltage.
SOLUTION: The magnetic clearance δ between a rotor 5 and a stator 6 is set to 0.55-0.65 mm, using a permanent magnet 17, 1.0 (T) or over in residual magnetic flux density. Consequently, even if the rotor 5 is rotated at high speed in case that the magnitude of stationary electric load connected is small, voltage more excessive than objective regulation voltage is not generated by the magnetic flux leaked from the permanent magnet 17, so excessive voltage more than specified is never applied to electric load or a battery mounted on the vehicle.

摘要翻译：要解决的问题：提供一种用于车辆的高度可靠的交流发电机，其可以在抑制涡流电压的发生的同时实现高输出。解决方案：使用永磁体17,1.0（T）或更高的剩余磁通密度，将转子5和定子6之间的磁隙δ设定为0.55-0.65mm。因此，即使转子5在连接的静止电负载的大小小的情况下高速旋转，则从永磁体17泄漏的磁通不会产生比目标调节电压过大的电压，所以过多的电压超过规定的范围不应用于电气负载或安装在车辆上的电池。版权所有（C）2004，JPO

摘要： PURPOSE:To improve the productivity and reduce the cost by a method wherein a bearing bush is formed of an annular sheet member placed through windows on the periphery thereof and is fixed to the central part of an end bracket by casting. CONSTITUTION:An iron bar member or an iron wire member is rolled into a flat sheet having the optimum thickness, and thereafter, through windows 2a are formed in the flat sheet by punching or machining whereby a bearing bush 2, provided with stoppers, is formed. Then, the bearing bush 2 is cast into a bearing box 3 for an end bracket 1 made of aluminum. Accordingly, a friction coefficient between the bearing bush 2, whose hardness is unified, and a bearing is small whereby the elongation of the life of the bush can be promoted while casting material is received in the through windows 2a upon casting the bearing bush 2 into the bracket 1 whereby the mutual connection between the bearing bush 2 and the bracket 1 can be retained rigidly. According to this method, productivity is improved and cost can be reduced.
