FOC库很复杂,我很难理解如何使用它。即使在阅读UM1052,UM1053之后。
在最高级别,我们可以启动/停止电机 if(MCI_GetSTMState(oMCI [M1])== IDLE){MCI_StartMotor(oMCI [M1]); } else {MCI_StopMotor(oMCI [M1]); } 但是如何设置速度和电流? 另一个问题 - 我也必须驱动直流电机。我应该为此目的设置什么? 有更广泛的例子吗? 以上来自于谷歌翻译 以下为原文 The FOC library is complicated and I have some difficulties to understand how to work with it. Even after reading UM1052, UM1053. On the highest level we can start/stop a motor if (MCI_GetSTMState(oMCI[M1]) == IDLE) { MCI_StartMotor(oMCI[M1]); } else { MCI_StopMotor(oMCI[M1]); } But how to set velocity and current? Another question - I have to drive DC motors as well. What should I set for this purpose? Is there more extensive examples? |

对于第二个问题,您的意思是有刷或无刷直流电机
PMSM FOC库用于驱动无刷库。 以上来自于谷歌翻译 以下为原文 For the second question, did you mean brushed or brushless DC motors PMSM FOC library is for driving the brushless ones. |

我需要驱动直流电机和BLDC。所以我认为有一种方法可以将固件设置为全桥驱动程序。
以上来自于谷歌翻译 以下为原文 I need to drive DC motors as well as BLDC. So I thought there is a way to set the firmware to behave like a full bridge driver. |

我不认为FOC SDK适用于驱动有刷直流电机。有刷电机的电极与无刷电机相比机械换向,我们需要复杂的算法来整流电机绕组。
如果您确实需要一个综合解决方案,请查看此文档: http://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/selection_guide/group0/52/61/48/55/a5/92/44/a4/sgstspin/files/sgstspin.pdf/jcr:内容/翻译/ en.sgstspin.pdf 以上来自于谷歌翻译 以下为原文 I don't think FOC SDK is applicable for driving Brushed DC motors. The poles in Brushed motors are mechanically commutated vs the Brushless ones where we need complex algorithms to commutate motor windings. If you do need an intergated solution, take a look at this document: http://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/selection_guide/group0/52/61/48/55/a5/92/44/a4/sgstspin/files/sgstspin.pdf/jcr:content/translations/en.sgstspin.pdf |

L6235或L6229将是完美的。但我需要10-15安培电流。
以上来自于谷歌翻译 以下为原文 L6235 or L6229 would be perfect. But I need current 10-15 ampere. |

嗨,
我确认无法修改FOC库以使其作为全桥驱动程序工作。 此外,与驱动有刷直流电动机的任务相比,这种驱动技术非常复杂。 我建议你从像这样的简单固件开始 http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-spn4.html 对于您需要的电流额定值,ST可以为您提供一整套栅极驱动器和mosfet。 恩里科 以上来自于谷歌翻译 以下为原文 Hi, I confirm the FOC library cannot be modified to make it work as a full-bridge driver. Moreover this driving technique is extremely complex compared to the task of driving a brushed DC motor. I suggest you to start from an easier firmware like the http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-spn4.html For the current ratings you need, ST can provide you a complete set of gate drivers and mosfets.
