摘　　要：针对传统电机测试系统中,无法直接实现对电机瞬态参数的测试以及电机加载时动态任意负载加载的要求或者实现成本较高的问题,以STM32+FPGA为核心构成电机测试系统的主控单元,结合ARM处理器的优越控制性能和FPGA的高速数据处理优势,并采用FSMC总线通信和数据乒乓处理算法对双核心进行控制和数据流不间断传输。最后,设计了一种嵌入式电机测试系统中的控制系统核心,可嵌入现有传统测功机系统中提升测功机瞬态参数测试和动态电机负载加载性能。实验结果表明,该系统能基本满足电机瞬态测试和动态加载的要求,可以实现测量被测电机转速转矩最快1 ms的数据刷新率,以及100M采样频率内的任意波形加载,加载误差在0.8%以内,较好的满足了电机瞬态测试和动态加载需求。In the traditional motor test system, it is impossible to directly test the transient parameters of the motor and the requirements of dynamic arbitrary load loading when the motor is loaded or the problem of high implementation cost. This research uses STM32+FPGA as the core to form the main control of the motor test system Unit, combines with the superior control performance of the ARM processor and the high-speed data processing advantages of FPGA. The FPGA and STM32 are controlled by the FSMC bus communication and data ping-pong algorithm. Through above method, there is a small-size control core board manufactured in the motor test system. It can be embedded in the existing traditional dynamometer system to improve the dynamometer transient parameter test and dynamic motor loading performance. Experimental results show that the system can basically meet the requirements of motor transient test and dynamic loading, and can achieve the fastest data refresh rate of 1 ms for measuring the measured motor’s speed and torque, and arbitrary waveform loading within 100 M sampling frequency, with a loading error of 0.8%. It satisfies the motor transient test and dynamic loading requirements.
