摘　　要：伺服电动机又称执行电动机,在自动控制系统中,用作执行元件,把所收到的电信号转换成电动机轴上的角位移或角速度输出。交流伺服电动机要克服自转现象,可通过把转子电阻设计足够大,其目的就是使转子在转动时产生制动转矩,在控制绕组不加电压时,能及时制动,消除自转现象。Servo motors, also known as execution, the automatic control system that is used for the implementation of components, the received electrical signal into the motor shaft angular displacement or angular velocity output. AC servo motor to overcome the phenomenon of rotation, the rotor resistance can be designed large enough, its purpose is to make the rotor in the rotation torque generated when braking, without the control winding voltage, brake in time, to eliminate the phenomenon of rotation.

关 键 词：伺服电动机 自转 转子电阻
