新能源汽车电驱和电机测试台架系统设计与应用

Design and Application of Test Bench System for Drive and Motor of New Energy Vehicle

针对新能源汽车车用驱动器及动力电机系统测试的要求,首先对车用永磁同步电机动态特性进行分析,并根据电机驱动器、电机的特点和测试要求进行台架测试系统设计,最后搭建一套完整的台架测试系统进行驱动器和电机的测试与完善。试验结果表明,所设计开发的台架测试系统平台能够稳定可靠运行,满足驱动器厂和电机厂的性能、可靠性和极限的测试需求,具有很强的实用性,对车用动力系统开发具有一定的参考价值。

According to the new energy vehicle drive and power motor system testing requirements,the dynamic characteristics of permanent magnet synchronous motor for vehicle were analyzed firstly,and a bench test system based on the motor driver and motor characteristics and testing requirements was designed.Finally,a complete bench test system was built to test and improve the driver and motor.The test results show that the test platform designed and developed can run stably and reliably,and can meet the driving test requirements of performance,reliability and limit of driver plant and electric machine plant.It has a strong practicability and a certain reference value for the development of vehicle power system.
