STEVAL-ESC001V1 - Workbench example doesn't work

[Slee.3]

Hi! I am trying to control sensorless BLDC motor using STEVAL-ESC001V1.

I finished profiling my motor and working on the example on Workbench

(STEVAL-ESC001V1 electronic speed control 5.4.0).

I opened the example on the workbench and set the motor parameters (I didn't change the name of the project)

and fed PWM through other STM32 kit.

Here are my external inputs and PWM signals I am generating (PWM is 490Hz).

I can hear the beep sound continuously without PWM signal and the motor barely moves like 1 degree changes per deep.

When I feed PWM signal, the beep sound is gone and the motor didn't move at all. Literally doing nothing.

(I was changing the PWM width from 1060us to 1700us, Still nothing)

What can be wrong here?

I am just guessing this can be happened due to the gain of OPAMP because I am using the big motor not like small ones for drones. It is 300W 3000RPM 12V 10A(Nominal).

Dear @Slee.3​ 

In the meantime, we published a patch to fix this code example (see https://community.st.com/s/question/0D53W00000HwV8RSAV).

Did you try it?

As you do not answer, I guess you don't have to solve this problem anymore, therefore I consider this thread closed.

If not, feel free to reopen it by posting a new answer.

The question has been set only to the "STM32 Motor Control" topic (the question is only about the STM32 MC SDK).
