8LS46伺服电机是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。伺服电机可使控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反应，在自动控制系统中，用作执行元件，且具有机电时间常数小、线性度高等特性，可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。

8LS46伺服电机分为直流和交流伺服电动机两大类。其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。

此外，交流伺服电机的工作原理是：8LS46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）。

8LS46 servo motor refers to the engine that controls the operation of mechanical components in the servo system, which is a supplementary motor indirect transmission device. The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has a small electromechanical time constant, high linearity characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft.

8LS46 servo motor is divided into DC and AC servo motor two categories. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of the torque.

In addition, the working principle of the AC servo motor is: the rotor inside the 8LS46 servo motor is a permanent magnet, the U/V/W three-phase electric field controlled by the driver, the rotor rotates under the action of this magnetic field, while the motor comes with the encoder feedback signal to the driver, the driver according to the feedback value compared with the target value, adjust the rotor rotation Angle. The accuracy of the servo motor is determined by the accuracy of the encoder (number of lines).
