摘要
针对一款100k W新能源汽车驱动用永磁同步电机低速大扭矩和高速恒功率区弱磁调速范围宽的要求,采用"V"型转子磁路结构。考虑电机实际控制策略在转折转速以内为最大转矩电流比(MTPA)控制,转折转速以上为弱磁控制,结合ANSYS Maxwell对电机主要性能进行了电磁场仿真分析,确定永磁同步电机各主要参数。并对样机进行了空载试验、负载试验。将样机试验测试结果与电磁场仿真计算结果进行对比分析。
For the requirements of wide flux-weakening speed regulation range at hightorque low-speed and constant-power high-speed zones of a 100 k W permanent-magnet synchronous motor（ PMSM） for new-energy vehicle,the magnetic circuit structure of V-shaped rotor is adopted. Considering that the actual control strategy of the motor is the maximum torque per ampere（ MTPA） control within the turning speed and the flux-weakening control above the turning speed,the electromagnetic field simulation analysis on main performance of PMSM is carried out by ANSYS Maxwell,and the main parameters of PMSM is determined. The no-load test and on-load test of sample motor is carried out,and comparative analysis is carried out between the test data of sample motor and the simulation calculation results of electromagnetic field.
