设计基于stm32电机控制的解决方案入门

你好，
您是否已经拥有一些硬件或者您正在设计定制板？
如果您还没有硬件，我建议您查看ST控制板和电源板。
基本上，对于FOC我们不需要Bemf采样（我们需要6步）。我们读到了需要放大的电流。我们支持1个分流器或3个分流器或ICS拓扑结构。如果您使用STM32F303，则可以在外部或内部进行放大，对于用于过流保护的比较器也是如此。
我们的工具配置ST Motorcontrol Workbench允许您配置它。当然，如果从ST报价开始，将会更容易，因为工具已经知道了参数。
一个很好的起点可能是在这里下载我们的5.1.1库：

 它包含配置工具ST Motorcontrol工作台。
问候

Hello,
Do you already have some hardware or are you in the process of designing a custom board ?
If you do not have HW yet, I would suggest you to have a look in ST control boards and power boards.
Basically, for FOC we do not need Bemf sampling (we need it for 6 steps). We read current that need to be amplified. We support 1 shunt or 3 shunts or ICS topology. Amplification can be done externally or internally if you use a STM32F303 for instance, the same for comparators used for over current protection.
Our tool configuration ST Motorcontrol Workbench will allow you to configure this. Of course it will be much easier if you start from ST offer, as parameters are already known from the tool.
A good starting point could be the download of our 5.1.1 library here :

it contains the configuration tool ST Motorcontrol workbench.

我有一些硬件，它包括：
 
- 栅极驱动器 - 6个MOSFET设置
- PSOC4 - 基于霍尔传感器的控制
我正试图转向无传感器控制，我将为此制作一块新板。
这是我从你的评论中得出的结论：
- 当我以6步骤运行电机时，BEMF需要采样 - 无传感器模式（我不打算）
- 对于FOC，我将使用1/3分流型或绝缘电流传感器。
问：当我去设置分流器时，我得到了这个，我应该坚持默认值 - 确保它覆盖我当前的范围或者我是否需要调整增益设置或其他？我错过了配置它的目标。

I have some hardware, it includes:

- Gate drivers- 6 MOSFET setup
- PSOC4 - hall sensor based control
I am trying to move to sensorless control for which I shall make a new board.
This is what I have concluded from your comment:
- BEMF is sampling is needed when I run the motor in 6 step - sensor less mode (which I am not planning to)
- For FOC I will have to go with a 1/3 shunt profile or insulated current sensors.
Q:When I go to setup the shunt, I get this, should I stick to default values - making sure it covers my current range or do I need to adjust the gain settings or something else ? I am missing the objective of configuring this.

你好，
我真的建议你看看我们的电源板解决方案。我们所有的原理图都是免费提供的。
我不知道你的VBUS是什么，但也许你可以从这个参考开始：

 原理图如下：
http://www.st.com/resource/en/schematic_pack/x-nucleo-ihm08m1_schematic.pdf
 该板可以同时执行两个操作，3个分流器1分流FOC或六个步骤。保持对你有意义的部分。
当您选择赛普拉斯PSOC4控制器时，我们的工作台工具对您来说毫无用处......
问候

Hello,
I really advise you to look at our power boards solution. All our schematics are available for free.  
I do not know what is your VBUS, but perhaps you can start with this reference :

http://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-move-actuate-hw/x-nucleo-ihm08m1.html
the schematic is here :
http://www.st.com/resource/en/schematic_pack/x-nucleo-ihm08m1_schematic.pdf
This board can do both, 3 Shunts 1 shunt FOC , or Six steps. keep the parts that make sense for you .
As you choose a Cypress PSOC4 controller, our workbench tool will be useless for you ...
