你好， 我想将最新的FOC库用于小型PMSM电机。我正在使用STM32F303VCT6 MCU，我想使用内部PGA。但是马达根本没有运转。启动序列开始，但具有非常高的电流消耗（我在WB中设置的更高）。我最终认为AD转换器可能没有给出正确的值。我主要看Vbus电压测量。测量值不正确。它应该是~325V，但从MCU读取给我一个~189V的值，并在几秒钟后下降到~21V。板载电压是正确的，MCU ADC工作正常 - 我的意思是板上没有任何损坏。我在StdLib中为STM32F3修改了示例项目，并从Vbus引脚转换了值。所以在我看来，在库中设置AD转换器有问题。 ADC不能测量Vbus的正确值，也可能测量相电流，这就是为什么电机在启动时会产生大电流并且不能运行的原因。 我在WB中附加我的设置。 也许我应该提一下，我使用KEIL MDK来编译库。 任何帮助/提示都会有所帮助。 谢谢。丹尼尔＃foc-adc #mcu＃foc-adc #foc＃foc-adc以上来自于谷歌翻译以下为原文 Hello, I would like to use the latest FOC library for small PMSM motor. I'm using STM32F303VCT6 MCU and I would like to use internal PGA. But motor doesn't run at all. Start sequence starts, but with very high current consuption (higher that I set in WB). I finaly fount that probably AD converter doesn't give a correct value. I see it mainly on Vbus voltage measurement. Measured value is not correct. It shoul be ~325V but reading from MCU give me a value ~189V and it fall down to ~21V after few seconds. Voltage on board is corrent, also MCU ADC works correct - I mean nothing is damaged on the board. I've check it with modified example project in StdLib for STM32F3 and it converts value from Vbus pin. So it seems to me, that something is wrong with setting of AD converter in library. ADC does not measure correct values of Vbus and probably also phase currents and that's why motor has during start so big current consuption and doesn't run. I'm attaching my settings in WB. Maybe I sould mention, that I use KEIL MDK to compile library. Any help/tips would be helpfull. Thanks. Daniel#foc-adc #mcu #foc-adc #foc #foc-adc
