Basic requirements of servo driver for motor
说道驱动器，我们先来说说，是使物体的方位.方位.状态等输出被控量能够跟从输入目标（或给定值）的任意改变的自动操控系统。它的主要任务是按操控指令的要求.对功率进行扩大.改换与调控等处理，使驱动设备输出的力矩.速度和方位操控的十分灵敏方便。一般来说，驱动用具稀有分钟乃至半小时内1.5倍以上的过载才能，在短时刻内能够过载4～6倍而不损坏。
Speaking of servo drive, we first talk about servo, servo is to make the object's orientation, azimuth, state and other output controllers can follow the input target (or a given value) of any change in the automatic control system. Its main task is to enlarge, change and adjust the power according to the control command, so that the output torque, speed and azimuth control of the driving equipment are very sensitive and convenient. Generally speaking, servo drive appliances can be overloaded more than 1.5 times in a few minutes or even half an hour, and can be overloaded 4-6 times in a short time without damage.
系统的开展阅历了由液压到电气的进程，电气系统依据所驱动上饶变压器类型分为（DC）系统和沟通（AC）系统。沟通系统按其选用的驱动上饶变压器类型又可分为永磁同步（SM型）电动机沟通系统和感应式异步（IM型）电动机沟通系统。

The development of servo system has experienced the process from hydraulic to electrical. Electrical servo system is divided into DC servo system and AC servo system according to the type of motor driven. The communication servo system can be divided into permanent magnet synchronous (SM) motor communication servo system and inductive asynchronous (IM) motor communication servo system according to the type of driving motor it chooses.

因为电动机存在上饶变压器结构杂乱，维修工作量大例如上饶变压器的电刷.换向器等则成为驱动技能开展的瓶颈。跟着微处理技能.电力电子技能的老练和沟通永磁上饶变压器资料的开展和使用，上饶变压器功率的进步和制作本钱的下降，沟通系统得到长足开展并将逐渐替代系统。
Because of the disorder of DC servo motor structure, maintenance workload such as brush and commutator becomes the bottleneck of DC servo driving skills. With the development and use of microprocessor, power electronics and communication permanent magnet motor data, the improvement of motor power and the decrease of manufacturing cost, communication servo system has been greatly developed and will gradually replace the DC servo system.
驱动器应该满意对上饶变压器的基本要求
The servo driver should be satisfied with the basic requirements of the motor.
1.从******速到最速上饶变压器都能平稳工作，转矩动摇要小，尤其在低速如0.1r/min或更低速时，仍有平稳的速度而无匍匐现象。
1. The motor can work smoothly from the lowest speed to the highest speed, and the torque shake should be small. Especially at low speed such as 0.1r/min or lower, there is still steady speed and no creeping phenomenon.
2.上饶变压器应具有大的较长时刻的过载才能，以满意低速大转矩的要求。一般上饶变压器要求在数分钟内过载4～6倍而不损坏。
2. the motor should have large overload for a long time to meet the requirement of low speed and large torque. The general DC servo motor requires 4~6 times overload in a few minutes without damage.
3.为了满意快速响应的要求，上饶变压器应有较小的转动惯量和大的堵转转矩，并具有尽可能小的时刻常数和发动电压。
3. In order to satisfy the requirement of fast response, the motor should have small moment of inertia and large stop torque, and have as little time constant and starting voltage as possible.
4.上饶变压器应能接受频繁启.制动和反转。
4. Motors should be able to receive frequent start, brake and reverse.
