摘要

针对目前电动汽车驱动电机试验台多是用于电机性能测试的现状,设计了用于电动汽车驱动电机典型工况模拟和故障信号采集的试验台;通过NI cRIO控制器、可编程控制器和比例-积分-微分(PID)控制实现被测电机的典型工况模拟,利用NI 9220和NI 9234采集模块完成了被测电机电流、温度、转速、转矩和振动多路故障信号的高速同步采集;基于实验室虚拟仪器集成环境(LabVIEW)平台开发了一套可以实现实时电机控制与信号显示的上位机软件;对被测电机进行负载实验。结果表明,电机控制效果良好,信号采集频率与精度可以满足要求,能够为电动汽车驱动电机的故障诊断和性能优化提供数据基础。
        In view of the current situation that most of the electric vehicle drive motor test bench were used for motor performance test, a test bench was designed for the typical working condition simulation and fault signal collection of the electric vehicle drive motor. The typical working condition of the measured motor was simulated by the NI cRIO controller, programmable logic controller and proportion-integral-differential(PID) control algorithm. The multi-channel signals such as current, torque, speed and vibration of the measured motor were collected in a high-speed and synchronous way by NI 9234 and NI 9220 acquisition card. A host computer software for real-time motor control and signal display was developed based on the laboratory virtual instrument engineering workbench(LabVIEW). Load test for the measured motor was carried out. The results show that the motor control effect is good, the signal acquisition frequency and precision can meet the requirements. The test bench can provide data basis for fault diagnosis and performance optimization of electric vehicle drive motor.
