摘　　要：分析了交流同步发电机电磁转矩特性,将同步发电机转子和电动机转子1∶1同轴连接,通过控制交流同步发电机的电磁转矩,可以对电动机施加不同程度的负载,达到加载的目的.经过理论与实验结果对比分析,证明了本方法的有效性,而且还可以针对不同的加载需求模拟实际工作中不同的负载变化情况.As motor is the main power source of life and production,it is particularly important to detectits feature when it is connected to loads. This study analyzes the AC synchronous generatorelectromagnetic torque characteristics, and makes the synchronous generator rotor and the motor rotor1 ： 1 coaxial connection. Synchronous generator is the load device of the motor. Through controllingthe AC synchronous generator,load in different degrees are applied to the motor. By comparing thetheoretical results with the experimental ones, this method proves to be feasible and effective. Themethod can also simulate different load varying situation for actual requirements.
