预告
I was attracted by motor during myundergraduate period. I just know it will be run if we connect it to the electric sources in the outset. with the deeping of learing.I study more control knowledge，such as speed control，location control，and Torque control（current control），even though I can not understand it completely.I want to learn it more and more.So I decided to start a open sources project by myself.of course，welcome you to join my team.
一直对电机驱动这 方面很感兴趣，从浅显的知道它通电就能转动，到后面的速度控制，位置控制，以及暂时还没搞明白的转矩控制（俗称电流环）。越发觉得自己被这个小东西深深的吸引了。开源项目很多，别人做的也比我好，但是，那终究是别人的，我只相信“此事要躬行”。
Today is July 13, 2020，I launch the project officely.My topic is make a DC motor driver with close-loop control.it includes speed,location and current control.Why i choice brushless DC motor? one reason is because it`s low prices.in the another one,it has less parameter,we can easily start it.Finally,DC motor is widely uesd.
现在是2020年7月13日，我打算开始电机驱动的第一个开源项目：带有位置速度电流环的有刷驱动。为什么选择有刷驱动呢？一方面是因为成本低，模型参数少，第二方面是这玩意用的比较多，作比赛，做小车，用有刷方便。
In the fact，I already finished the first version of PCB，As you can see in the figure below.All parameter list in the table.But I haven't had time to write the program.I am not satisfied with it.but I will continue to improve it.It`s too far for me that this project can help you,but I still this project can attractive you.I believe that the development of technoligy is endless
接下来是驱动驱动的一些参数，第一版的硬件我已经做出来了，虽然不满意，但是从原理上没问题。我不奢望我开源的项目能够帮助到多少人，但希望能吸引到一些志同道合的伙伴，共同成长。毕竟技术的道路是永无止境的。下面两张图是已经焊好的驱动，参数在表格里列出。
 
| 参数（parameter） | 值（value） | 备注（description） | | 供电电压（Supply Voltage） | 12V~36V | | | 最大电流（Max Current） | 10A | 保守值 | | 静态电流（Quiescent current） | 10mA | | | 主控芯片（ Control chip） | STM32F040K6T6 | ST | | 电流采集芯片（Current acquisition chip） | AD8418 | 亚德诺 | | MOSFET驱动芯片（MOS-gate drive IC） | EG3112 | 屹晶微 | | MOSFET | SED10070GG | NMOS |
The first step is always the most difficult.I will release my project in Github,but I should study it firstly.And the text description will posted in my series of blogs ---Open Sources Motor Driver.If you want to push the pacem please contact me by email1095490791@qq.com or lijiangtao_work@outlook.com.Nothing is impossible if you put your heart into it.
万事开头难，我会去研究一下github，源码等文件发布在github，文字说明发表在我的分栏【开源电机驱动】 ，催更邮箱：1095490791@qq.com。无论遇到什么困难，都不要怕，消除恐惧的最好办法就是面对恐惧，加油！奥里给。
