Stepper motor is an electromechanical component which can convert electric pulse signal into angular displacement or line position,and it has the advantages of easy open-loop control and no cumulative error.However,there are some problems for stepper motor in the applications where high precision is required,such as low-frequency oscillation,high-frequency step-out,etc.,leading to the unstable operation of stepper motor,so the subdivision drive control of stepper motor is proposed.This paper introduces the working principle of four-phase reaction-excited stepper motor,analyzes the advantages and disadvantages of FPGA drive and microcontroller driver,compares the advantages and disadvantages of the principles of PWM subdivision drive circuit and chopper subdivision driver,and proposes using EPGA chip to control the duty cycle of the PWM signal,thereby adjusting the current of each phase of stepper motor.On this basis the forward and reverse rotation,the normal operation and subdivision operation of stepper motor are realized.

失效就是（安全、性能）出问题.

主语：（我校举办的数学、物理、化学三个）短训班
谓语：开设了
宾语：农用数学、农用机电、和农作物栽培等课程
短训班开设了……
看出来没?主语是短训班,不能开设课程.
所以应该是：
我校举办了数学、物理、化学三个短训班,开设了农用数学、农用机电、和农作物栽培等课程,使教学直接为四个现代化服务.
这样就把主语改成了“我校”,后边是两个同类句式.
分析病句最重要的一种方法,就是分析成分,主语、谓语、宾语,是最主要的枝干,一般的语病都是在这三个上出错……

生活是离不开机电用品的,从事机电活动、日常里的都算机电人生.
这个题目是有动员你热爱机电的意思在.
可以用具体例子,来说明你原来不懂,很担心出问题或不能应对,但真去接触后,问题迎刃而解,后来反而热爱机电、离不开机电.
你自己实在没有像样的例子,可以写别人的.譬如堂兄表叔,乘车途中,车坏了司机摆弄好久,也发动不了.一位乘客说,你把某某另件拆开让我看.结果一看,真的是这里出问题.车很快就修好了,他觉的有技术真好,从此爱上技术了,后来成为很好的机电名手,在那一范围很有名声等等.

减速机与减速箱工作原理相同,通常情况下,减速机有固定的减速比,输出转数固定．而减速箱可以通过控制杆改变减速比,从而达到不同的输出转数.
减速箱：其到降低转速功用的一个齿轮箱组合在一个箱体内.此点应该没有争议!
*减速机：字面意思应该就是一台机器了,其存在驱动、转动单元.
日常工作中没有严格的区别!减速机可以称呼为减速箱

Stepper motors as actuators,electromechanical integration is one of the key products,widely used in a variety of automatic control systems.With the development of microelectronics and computer technology,increasing demand for stepper motors,all applications in all areas of the national economy.
Stepper motor is an electrical pulse into the angular displacement of the implementing agencies.When the stepper driver receives a pulse signal,it drives the direction of stepping motor rotation by setting a fixed point (called "step angle"),its angle of rotation is fixed step by step operation.Pulse number can be controlled by controlling the angular displacement,so as to achieve accurate positioning purposes; also can control the pulse frequency to control motor rotation speed and acceleration,so as to achieve speed control purposes.Stepper motor control can be used as a special motor,its no accumulation of error (accuracy of 100%) is widely used in various open-loop control.
Stepper motor driver is not with ordinary subdivision,such as:use of three-phase six-shot,five-phase 10 film and so on,use low speed vibration phenomena occur,resulting in lost step.
The use of a sub driver,in the process of stepping motor driven reduction step angle,increased step resolution,increase smoothness,which can effectively solve the problem step throw.
The speed of winding step power control and power of the frequency shift depending on the order of the stator power rotation.Put up with the switch control of power flow off the switch circuit,a microcontroller port access switch gate control terminal to realize the single chip microcomputer to control the stepping motor.Has the following advantages:
1.Using high-speed chip technology,fast response;
2.Fully digital control,powerful,position / speed / torque control;
3.Miniaturization and high efficiency can go to the direction of development;
4.Output current to meet more applications.
