Dear MCSDK users, MCSDK version 6.3.2 is now available: Download It here. This is a bug fix release and here are the main changes for this version: Motor Control Features: FOC Fixed CORDIC Modulus computation in case of negative alpha value Fixed iss...

Board Manager documentation is out !

The documentation of the Board descriptions format is now available on Motor Control Boards Description Wiki page, this documentation is compatible with MCSDK versions from 6.1.2. Board Descriptions are used by the ST motor-control workbench to enabl...

How to write a Motor control post to get a response quickly

In order to have a quick response to your forum posts, the best way to ask the question is:- Give the version of the MCSDK used. - Say if the problem concerns a tool (MC Workbench, Motor Pilot, Motor Profiler, etc...) - Provide picture of tools inter...

Resolved! I want to confirm that the BLDC motor pole number information for ST MC WB . Is the pole number for rotor or stator? I think that the pole pair number is for rotor(number of magnetic / 2). Thank you

Resolved! Does MC_SDK require the use of coprocessor?

We are developing an application to drive dual PMSM motors with STM32H745 and FOC algorithms and resolver sensor. The inner current loops are executed at 10 kHz, PWM carrier frequency is set to 20 kHz. Is it feasible o run the entire application code...

Resolved! Recommended setup for small motor position control?

I have a small BLDC motor with magnetic encoder (like this one https://www.aliexpress.com/item/33053552345.html) and would like to set up a position control. The NUCLEO-IHM03 comes pretty close https://www.st.com/content/st_com/en/products/evaluatio...

Use MotorControl Workbench for STM32f405 (not supported MCU)

I would like to use MCSDK with STM32F405RG, but my problem is, that in MC Workbench, this MCU is not in the list, I found only the STM32F407IG, which is the closest to F405. I tried to generate for F407 (TrueStudio), and than open the CubeMX file, cr...

Resolved! we use the STM32F302R8T6 to FOC pmsm motor control,and use the hall sensor,use the foc lib by st,now the question is the torque is small and motor will seizing-up in slow speed( 10-100rpm)，how to resolve this problem? thanks !

Resolved! Elegant way to generate 6 variable frequency GPIOs with STM32F446RE.

Hello forum, my goal is to emulate a DC motor family with some electronics and an STM32F446RE.The current setup is, an ECU to control 6 of these motors, 6 coils of the motor family as load, 6 current sensors, running in the STM32, and from there i ne...

Resolved! Trapezoidal control for bldc drives

I am developing bldc drives using stm32f103c8t6 MCU. And by using inverter circuit we drive the bldc motor using stm32. Block diagram of drive is shown belowUsing register language, we coded logically for 6 step commutation. And that works fine.But ...

Resolved! IAR embedded WB from CubeMX to drive IHM003 motor control dev kit error : Error[Li016]: size limit exceeded. The application needs 0x86b6 (34'486) bytes

When I run code in IAR embedded WB from CubeMX to drive IHM003 motor control dev kit initial project (same as in getting started video) , I have got this error Error[Li016]: size limit exceeded. The application needs 0x86b6 (34'486) bytes, which is g...

Resolved! Corrrect way to update frequency (ARR) to generate step pulse for stepper motor using stepper driver drv8711 and stm32 micro controller.

Hello,I am Sai hope you are doing well I am facing some issues with the timers .I am using stm32f4,f7 micro controller to pulse step input of stepper motor driver. I have configured my timer using HAL layer. i want sweep the frequency from 100hz to s...

Resolved! Is it possible to change the rotation direction of the motor in sensorless mode in some way?

Hello everyone,I would like to use my setup (using an stm32g431cb) to rotate 3 circle and than rotate 3 circle in the other direction, with 1500 rpm.Now my motor just doing the rotation in one direction continously. I tried to use the following funct...
