电力传动系统中，对电机控制装置的测试一般采用由电机及机械负栽等构成的测试平台。文中提出利用电子电子变换器模拟电机工作特性从而取代上述测试平台的方案，用于电机控制装置的考核测试。构造了基于精确电机模型的在线电机仿真器．用于实时计算电枢电流、转速及电磁转矩等电机状态量。将背靠背型双PWM变换器应用于直流电机模拟器．分析了其模拟直流电机四象限运行的工作机理。仿真结果验证了电机仿真器的在线计算值与电机实际运行时的状态量基本一致，然后验证了电机模拟器的实际模拟效果，从而证明了电机模拟器的有效性和可行性。

In the power drag system, the test of driving device needs a complex load system consisting of rotating motor and mechanical load, A system of simulating DC motor and its load with power electronic converter is proposed, which can be used in the acceptance test of motor driving system. The systematic principle is defined and a DC motor simulator is built to calculate the armature current, the motor speed and the electromagnetic torque. On the basis of Boost convertor, a novel method using the dual PWM converter is put forward. A simulating platform is established to test the simulator, and the simulation results verify the feasibility of motor simulator.
