Description

一种汽车用的稀土永磁发电机，适于汽车点火系统，蓄电池充电和用电设备作为电源。
目前汽车发电机普遍采用由电刷、滑环和转子励磁绕组构成的交流发电机。其故障率高，需要蓄电池励磁电源，由于电刷与滑环的摩擦损耗，汽车快速运行时转子励磁绕组易飞出而造成事故。
本实用新型的目的是将稀土永磁发电机作为汽车点火系统，蓄电池充电及其用电设备的电源，通过永磁发电机和电励磁电机组合，由电励磁发电机的励磁电流调节达到自动调压，减少行车事故，提高运行效率。
本实用新型由爪极式电励磁电机作辅助磁极与稀土永磁发电机并联构成汽车用的稀土永磁发电机。其中发电机的稀土永磁体转子6与电励磁辅助磁极的空爪磁极3之间相夹隔磁材料5，同时紧拼在转轴7的同一轴线上与定子4匹配，控制绕组2没在控制绕组支架3上。
本实用新型所提供的汽车稀土永磁发电机不需励磁电源就可以发电，转子无励磁绕组，无电刷、无滑环，励磁损耗和电刷与滑环的摩擦损耗均可避免，而且宽幅自动调压，低速行驶时也能满足照明电、电器用电及蓄电池充电的需要，其结构简单、行驶效率高，故障率低、维护方便等。经小客车、解放牌汽车行驶试用，从未因蓄电池无电而发生停车事故。
附图：永磁体转子6与电励磁电机空爪磁极3组合结构图。
实施本实用新型参照附图，在稀土永磁体6与一副电励磁空爪磁极3之间放置隔磁材料，然后紧拼在转轴7的同一轴线上，与定子4匹配，电励磁辅助磁极3及调压线圈位于稀土永磁体转子6的驱动端（带轮端），或空爪及调压线圈位于稀土永磁体转子6的硅整流输出端；当控制绕组2通入直流电后，产生的磁通φ∧与永磁体产生的磁通φm共同向空气隙提供气隙磁密。
