摘要
为解决传统电涡流缓速器持续使用汽车电器用电的问题和节约能源,提出一种新型自励式电涡流缓速器结构,运用有限元法对外转子发电机部分的电磁场进行分析,通过台架试验对发电机特性进行测试。结果表明,仿真结果与实测数据吻合较好,电磁转矩可达36~95N·m,供电电流在转速300r/min以上能够持续达到55A,满足车辆需求。
In order to solve the problem that the traditional eddy current retarder continues to use the electric power of the automobile and save the energy, a new type of self- excited eddy-current retarder structure is proposed. The finite element method is used to analyze the electromagnetic field of the outer-rotor generator. The characteristics of the generator are tested by bench test. The results show that the simulation results are in good agreement with the measured data where the electromagnetic torque can reach 36~95N·m, and the supply current can reach 55A at the speed of 300r / min to meet the vehicle demand.
