MCSDK 6.3.2 is out !

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...

Motor power reading issue over 3000 watt.

We devlope our own board based on evspin32f0602 and modified it for 40 amp. We have problem to read motor power beyond 3000 watt.

HW + SW solutions for Brushless FOC command motors

Hello, we want to develop a testbench for 48V up to 60V brushless motors using STM32 FOC SDK.According to ST solutions we hesitate between 2 HW solutions :1. STSPIN32G4 : eval board with driver/power and mcu2. STEVAL-CTM009V (Power/Drivers) + NUCLEO-...

Resolved! How to switch from torque mode to speed mode while motor is running?

We're using STM32 MCSDK to control a high torque BLDC motor. The motor is equiped with hall sensors. Due to high torque at startup, we start the motor in torque mode. When running, we would need the speed control mode.But if we change the control mod...

Resolved! Hello. How can I change the direction of rotation with b-g431b-esc1 or a STEVAL-PTOOL1V1 boards? I can't find info on this. Thanks in advance for the answer. Béla

Resolved! How to use or program STM32F103CB MCU on EVSPIN32G4?

Hi there,on the EVSPIN32G4 are the STM32G431 MCU and the STM32F103CB MCU. Currently I only have the STM code generation programmed forSTM32G431 MCU. Is it possible to program the STM32F103CB MCU with the STM Workbench too, so that I can e.g. control ...

Resolved! Hello, i am using the evalboard EVSPIN32G4 and my question is: Can you use an external pin as an input for a fault signal? For example if this external signal switches HIGH or LOW the Gate Signals will turn low and all MOSFETs will open? Thanks!

I want to control the MPS motor driver and magnetic sensor board together By STM32F103 series. Is there any possible Stm32mxcube or Motor Control Bench connection with Mps EVAL boards? We tried to connect custom boards. Stm32 GUI will be more useful.

MPU6050, doesn't work fine

Hi, i've made a project called "propeller arm". This project is composed of a dc motor(controlled by a mosfet) and an IMU(MPU6050). I've used a complementary filter to measure the tilt angle and this works fine. For the throttle control i've used a l...

STM32G4 + STDRIVE101 + STL7DN6LF3. Sensored and FOC Control. Never goes below a certain RPM; is it possible to go at slow speed or superslow speed using FOC? At startup the motor goes smooth if without load, instead, with load goes jerky.

If you manage to block the motor the torque will rise and rise, when it unblocks goes very fast, trying to regain the missed spins.
