首先介绍了电动汽车用永磁同步电机(PMSM)运行特性和控制器输出特点。然后根据GB/T 18488—2015《电动汽车用驱动电机系统》标准规定的技术条件和试验方法,结合电动汽车用PMSM生产工艺规划,设计了电动汽车用PMSM在线检测工艺流程。在此基础上,设计了电动汽车用PMSM在线性能检测的测试系统,系统应用了先进的变频测量技术和计算机控制测量技术,能够按照相关的标准规定很好地完成电机在线性能检测。最后进行试验验证,结果表明:该系统测量精确、运行稳定、操作简便、自动化程度较高,具有较高的设计参考价值。

The running characteristics and controller output characteristics of permanent magnet synchronous motor (PMSM) for electric vehicle were introduced. According to the technical conditions and test methods specified in GB/T 18488-2015 “drive motor system for electric vehicle”, the online inspection process for electric vehicle PMSM was designed in combination with the production process planning of PMSM for electric vehicle. On this basis, the online performance inspection system for electric vehicle PMSM was designed, and the advanced frequency conversion measurement technology and computer control measurement technology were applied in the system. Experimental results showed that the system was accurate, stable, easy to operate and highly automatic, and had high design reference value.
