BLDC速度调节不起作用

大家好，


我正在尝试使用STM32 MC PMSM FOC SDK v3.4库运行三相BLDC电机。我有最新的ST MC Workbench。我有以下问题：

当我启动电机时，它开始旋转，但我无法调节它的速度。无论我设定什么速度，我都会保持准确的速度。
只有当我将速度设置为低于大约1300 rpm时，电机才会停止，并且我会收到“速度反馈”错误。即使我将目标速度设置为0，电机也在旋转。
电机也消耗太多电流。它没有任何负载，所以最多需要100mA才能旋转。但它消耗1A并且只是因为我的电压源的电流限制为1A。

霍尔传感器，电流读数和电压检测工作正常。

哪里可能有问题？

非常感谢您的回复。

Hello guys,


I'm trying to run a three-phase BLDC motor with STM32 MC PMSM FOC SDK v3.4 library. I have the latest ST MC Workbench. I have a following problem:

When I start the motor, it begins to spin, but I am unable to regulate a speed of it. I keeps an exact speed no matter what speed I set.  
Only when I set the speed lower than approximately 1300 rpm, the motor stops and I get a ''speed feedback'' error. Motor is also spinning even if I set target speed to 0.
The motor also consumes too much current. It doesn't have any load on it so it should take maximum of 100mA to spin. But it consumes 1A and only because I have a current limit of 1A on my voltage source.

Hall sensors, current reading and voltage sensing are working fine.

Where could be a problem?   

Thank you very much for your responses.
