摘要:
在满足轨道交通使用的原有异步电机的外特性和结构约束的条件下，基于一种新型永磁同步牵引电机的转子磁路的拓扑结构，设计了一款新型少磁化永磁同步电机。通过对电机转子结构、转矩特性、损耗和线路能耗进行比较和综合评价表明,通过合理设计电机的磁路，可以充分利用永磁转矩和磁阻转矩实现更宽的工作区，同时对比现轨道交通运行的电机耗能。该新型少磁化永磁同步牵引电机节能效果显著。
Abstracts:
In accordance with satisfying the external characteristics and structural constraints of original induction motor in rail transit, a novel less magnetized permanent magnet synchronous motor is designed based on the topology structure of the rotor magnetic circuit of a new type permanent magnet synchronous traction motor. By comparing and comprehensively evaluating the rotor structure, torque characteristics, loss and line energy consumption of the motor, the results show that by designing the magnetic circuit of motor reasonably, the permanent magnet torque and reluctance torque can be fully utilized to realize a wider working area. At the same time, compared with the energy consumption of the current motor operated in rail transit, the energy saving effect of the novel less magnetized permanent magnet synchronous traction motor is evidently more remarkable.
