Can I use NUCLEO-G474RE with Motor Control Workbench for a 3-phase AC motor?

[anuragkr]

Hello ST Community,

I am planning to use the NUCLEO-G474RE (STM32G474RE) for controlling a 3-phase AC motor using STM32 Motor Control Workbench (MCSDK).

I would like to know:

1. Is the NUCLEO-G474RE supported for 3-phase AC  induction motor control using Motor Control Workbench?

2. Can Motor Control Workbench generate the required 6 PWM signals for a 3-phase inverter?

3. Does MCSDK support 3-phase induction motor (ACIM) control on STM32G474RE?

4. If yes, which control method is recommended—V/f, sensorless FOC, or encoder-based FOC?

5. Does ST provide a ready-made firmware/example project for this setup?

6. What ST power stage/inverter board would you recommend for testing with the NUCLEO-G474RE?

My expected application is a 3-phase AC motor drive, and I am evaluating the STM32G474RE for production use.

Thank you.

The MCU block diagram Figure 1. STM32G474xB/xC/xE block diagram on the datasheet shows eight PWM outputs and 16 bit timer for each so that’s intended for applications like motor control.

You can check NUCLEO-G474RE schematic and use ST Core MX and IDE to look at pinouts for PWM (and alternate pinouts) and configure for ports that NUCLEO-G474RE makes available.

I can’t answer your questions but I would expect that there is full Motor Control support.

“My expected application is a 3-phase AC motor drive, and I am evaluating the STM32G474RE for production use.” this is the classic application for STM32 with multiple PWM outputs.

The pdf schematic shows six of the PWM pins brought out to headers:-
