摘　　要：基于转筒式电涡流缓速器与永磁发电机功能相结合的思想,提出了一种自励式电涡流缓速器的方案,并设计和制造了制动转矩为500N.m的自励式缓速器样机。最后在台架上进行了自励式缓速器的制动转矩、转筒温度和1500r/min拖磨试验,揭示了自励式缓速器的某些特性。Based on an idea of combining the functions of rotor-type eddy current retarder and permanent magnet generator,a scheme of self-excited retarder is proposed,and a self-excited retarder prototype with a braking torque of 500N·m is designed and produced.Finally a series tests including tests on braking torque and rotor temperature and 1 500r/min motoring test are conducted on test bench with some characteristics of self-excited retarder revealed.
