摘  要:永磁有刷直流电机被广泛应用于汽车领域,“碳汇计划”要求汽车能源消耗进一步降低,因此电机效率优化问题也日益突出。文中以车载冷却风扇用的永磁有刷直流电动机为研究对象,针对电机效率低下问题,采用Maxwell有限元分析软件,通过仿真参数化分析转子叠片长度、叠片槽形、绕组线径、绕组节距以及绕线匝数对电机性能的影响,结合仿真结果以及实际生产情况,确定可行的电机效率优化方案。依据优化方案制作样件进行实测,测试数据显示电机效率提升约4.8%,电机效率优化效果明显。Permanent magnet brush DC motor is widely used in the automotive field."Carbon sink Plan"requires the further reduction of automotive energy consumption,so the optimization problem of motor efficiency is becoming increasingly prominent.Based on vehicle cooling fan with permanent magnet brush DC motor as the research object,in view of the motor inefficiencies,using the finite element analysis software Maxwell,through simulation and parametric analysis of the rotor lamination length,laminated slots,winding wire diameter,winding pitch,winding circle number influences the performance of motor,combined with the simulation results and actual production conditions,determine the feasible motor efficiency optimization scheme.According to the optimization scheme,the sample is made and measured.The test data show that the motor efficiency is improved by 4.8%,and the optimization effect of motor efficiency is obvious.
