STM32 BLDC driver advanced configuration

[Vatech]

TL;DR Summary

I had to get into driving a BLDC motor due to a project. I have no previous experience on driving an BLDC motor and i have only one board available to test ( X-NUCLEO-IHM08M1 ) due to the fact that currently is hard to find globally .

Hello Community,

i have a X-NUCLEO-IHM08M1 BLDC driver which will be controlled by a HMI (generic industrial product) combined with Nucleo nucleo-f401re.

I developed the HMI part and currently i work on communication between the HMI and the Nucleo.
I would appreciate any help to configure the BLDC driver board (X-NUCLEO-IHM08M1 ).

I know they may need to be replaced surface mounted capacitors, remove resistors, but i would not like to risk to try many cases on same board.
My BLDC motor is a 3 Phase, 4 Pole 36V 4000RPM 0.44Nm 184W 7.3A , 21A_Peak_Current
My Power source is a 36V 15A SMPS

I need to limit the current under the 15A and be able to configure an software controlled acceleration
I do not know if it should be drived by trapezoidal mode , FOC or other, i do not have oscilloscope to rotate the motor and see the signal produced.
Thank you in advance

The best way to configure the X-NUCLEO-IHM08M1 BLDC driver is to check the datasheet of your motor and see what type of control it needs. Depending on the motor, you may need to use trapezoidal mode, FOC, or some other type of control. You can then use the datasheet to adjust the current limit and acceleration settings accordingly. Additionally, you can use an oscilloscope to rotate the motor and measure the signal produced, which will help you confirm that the settings are correct.
