Hi, I need to apply HFI for controlling a sensorless BLDC motor in low speed. However, the speed sensor option of 'HFI+Observer' in the STM32 SDK 5.3.1 workbench is not supported. How to address this problem? Thanks!

It seems that the feature is available in older version of SDK such as 4.3. However, I could not find any old version installation package online now. Any idea?

The HFI feature is not supported for the moment because we are not able to find a motor matching HFI requirement in order to test it.

If you do have such kind of motor that is able to do HFI with 4.3 release please let us know.

Regards

Cedric

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
