摘　　要：微型直流电机是微型精密仪器的重要部件,提出一种基于光耦原理的微型直流电机测试系统,该系统由红外发光管、红外接收管和透光率均匀变化的光密度片组成,通过微控制器控制可测定电机的转速、转角精度、寿命等参数。系统成本低,精度较高,操作简单,具有实用价值。The DC micro-motor plays a key role in the precise instruments. The DC micro-motor test system based on the principle of optocoupler was presented, which was composed of infrared light-emitting diode, infrared light-receiving triode and optical density disk whose transmittance features linearity. The parameters including velocity of motor, precision of angle and life span could be measured with the microcontroller. It has the advantages of low cost, high precision, and easy handling over other motor test systems with practical value.
