A power board to the STM32 NUCLEO-64 401RE board to control two 3-phase BLDC motors?

[Boris_L]

Hello. Could someone please recommend a good power board that can power and control two gimbal 3-phase BLDC 12V motors with encoders AS5048A https://www.sparkfun.com/gimbal-motor-with-encoder-12v-587rpm.html ? I use the STM32 NUCLEO-64 F401RE microcontroller board. Thank you.

Hello @Boris_L,

A modified X-NUCLEO-IHM09M1 is required. For more information, see the referenced post.

Hello GMA,

Based on your last post, I made the configuration consisting of the STM32G474E-EVAL microcontroller board, the two X-NUCLEO-IHM09MMOD connectors, the two X-NUCLEO-IMH11M1 motor-drivers (power boards), and the two gimbal GNM2804H-100T motors. Please see the screenshot attached. However, it shows "No Algorithm is available for this hardware configuration" when I hover a cursor over the red triangle in the left top corner. Moreover, it shows warnings and errors. Could you please advise what to do next? Please notice that I will need to later change the parameters of the motors because I use the two Sparkfun 9V 3-Phase BLDC motors that I mentioned earlier.

Hello @Boris_L,

On your previous post, on mentioned "STM32G474E-EVAL1 microcontroller board, two X-NUCLEO-IHM07M1 motor-driver boards", the modified X-NUCLEO-IHM09M1 board is X-NUCLEO-IHM07M1 oriented.

Hello GMA,

I am sorry. I use the two gimbal Sparkfun 12V 3-Phase BLDC motors with encoders AS5048A. What connector (adapter) would you recommend if I used the two X-NUCLEO-IMH11M1 motor-drivers (power boards) instead of the two X-NUCLEO-IHM07M1 motor-drivers (power boards)? Thank you. 

Note: It seems that the X-NUCLEO-IMH11M1 motor-driver board is better for the 12V motors because the voltage range and the current range are smaller.

Hello @Boris_L,

You can take inspiration from the modified X-NUCLEO-IHM09M1 for the X-NUCLEO-IHM07M1 to adapt an X-NUCLEO-IHM09M1 for the X-NUCLEO-IMH11M1.

Dear GMA,

I am just an electrical engineering sophomore. Though I have some physics and mathematics background, I am not so good about electronics and programming yet. Moreover, adapting the hardware is a half of the story. The other half is writing a file of the adapted hardware for the STM32 Motor Control Software Development Kit (Workbench). 

I could try to make the first half. However, writing a file for the Workbench may be problematic for me. I know Python programming (beginner level). I have just begun to learn C programming. 

I want to use your company hardware, except the electromotors, because I need pancake-shaped electromotors for our project. In my view, if your company sells the products (STM32G474E-EVAL and X-NUCLEO-IMH11M1), then it would be better for your company to also sell appropriate adapters and software. wouldn't be? I like your company products and I would like to continue to use them.
