交流伺服电机的工作原理交流伺服电机内部的转子是永磁铁，驱动器控制的U/V/W三相电形成电磁场，转子在此磁场的作用下转动，同时电机自带的编码器反馈信号给驱动器，驱动器根据反馈值与目标值进行比较，调整转子转动的角度。伺服电机的精度决定于编码器的精度（线数)。

交流伺服电机的工作原理和单相感应电动机无本质上的差异。但是，交流伺服电机必须具备一个性能，就是能克服交流伺服电机的所谓“自转”现象，即无控制信号时，它不应转动，特别是

当它已在转动时，如果控制信号消失，它应能立即停止转动。而普通的感应电动机转动起来以后，如控制信号消失，往往仍在继续转动,

The rotor inside the AC servo motor is a permanent magnet, and the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder of the motor comes with a feedback signal to the driver, and the driver compares the feedback value with the target value to adjust the rotor rotation Angle. The accuracy of the servo motor is determined by the accuracy of the encoder (number of lines).

The working principle of AC servo motor is not fundamentally different from that of single-phase induction motor. However, the AC servo motor must have a performance that can overcome the so-called "rotation" phenomenon of the AC servo motor, that is, when there is no control signal, it should not rotate, especially when it is already rotating, if the control signal disappears, it should be able to stop rotating immediately. After the ordinary induction motor rotates, if the control signal disappears, it often continues to rotate.
