Motor power at 50W-3000W voltage 12V-110V

1.伺服主要靠脉冲来定位，基本上可以这样理解，伺服电机接收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现位移，因为，伺服电机本身具备发出脉冲的功能，所以伺服电机每旋转一个角度，都会发出对应数量的脉冲，这样，和伺服电机接受的脉冲形成了呼应，或者叫闭环，如此一来，系统就会知道发了多少脉冲给伺服电机，同时又收了多少脉冲回来，这样，就能够很精确的控制电机的转动，从而实现精确的定位，可以达到0.001mm。

Servo depends mainly on the pulse to locate, basically can understand so, servo motor receives a pulse, begins to rotate a pulse corresponds to the angle, thus the displacement, because, servo motor itself has a function of pulse, so servo motor rotates an angle degree will issued corresponding to the number of pulses, accept it, and servo motor pulse echoes, or call closed loop. In this way, system will know how many pulses to the servo motor, also received a number of pulse back, so that we can accurately control the motor rotation, so as to achieve accurate positioning, can reach 0.001mm.

直流伺服电机特指直流有刷伺服电机——电机成本高结构复杂，启动转矩大，调速范围宽，控制容易，需要维护，但维护不方便（换碳刷），会产生电磁干扰，对环境有要求。因此它可以用于对成本敏感的普通工业和民用场合。

DC servo motor, in particular to a DC brushless servo motor motor is high in cost structure complex, starting torque, wide speed range, easy control, need to maintain, but maintenance is not convenient (f brush), electromagnetic interference (EMI), on the environment. So it can be used in cost sensitive general industrial and civil applications.

直流伺服电机不包括直流无刷伺服电机——电机体积小，重量轻，出力大，响应快，速度高，惯量小，转动平滑，力矩稳定，电机功率有局限做不大。容易实现智能化，其电子换相方式灵活，可以方波换相或正弦波换相。电机免维护不存在碳刷损耗的情况，效率很高，运行温度低噪音小，电磁辐射很小，长寿命，可用于各种环境。

DC servo motor does not include DC brushless servo motor -- motor has the advantages of small volume, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque is stable, motor power is limited or not. Easy to realize intelligent, the electronic commutation method is flexible, can square wave commutation or sine wave commutation. Motor maintenance free, there is no carbon brush loss, high efficiency, low operating temperature low noise, electromagnetic radiation is very small, long life, for a variety of environments.
