Discuss STM32 solutions for motor control, including PID tuning, sensorless operation, ADC noise, custom algorithms, and more.
Dear MCSDK users, The full MCSDK documentation is embedded in the Motor Control Workbench tool. Refer to Workbench tool > About > Documentations > Documentation.This document provides: Introduction: Includes startup guide links for MCSDK, HSO featu...
Dear MCSDK users, MCSDK version 6.4.0 is now available: Download It here. This version of the new Motor Control SDK 6 series (X-CUBE-MCDSK) provides mainly FOC and 6Step improvements, here are the main changes for this version: Motor Control Features...
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...
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...
Dear All,I am currently working on a 10 kW motor drive for controlling a PMSM in an automotive traction application, utilizing a Field-Oriented Control (FOC) algorithm. I am facing a challenge with position extraction from the motor’s Hall sensors.Th...
I have a custom board (G491) with a 1-shunt driver and Hall sensors I have been using with MCSDK 6.3.2 with no issue.When I saw the Release Notes of 6.4.0 I decided to give it a try, I wanted to try out the current monitoring.The workspace project wa...
Hi there;I'm trying to muddle my way through my first design with a motor driver that includes current sensing. This is for a battery-powered device, operating with an stm32f4 at 3.3v. My motor is a small gimbal-style motor, which I intend to run at ...
I was testing a BLDC motor with Hall-effect sensors at very low speed. This worked ok with v6.3.2, but with v6.4.1, if the speed reference is low, the motor don't even start.If I manually move the motor, sometimes it starts and sometimes it throws an...
I have a custom board with a STM32G491 with a single-shunt driver for 6-step with hall effect sensors.One of the motors I have has a hall sensor placement close to 120°. I followed the process described in documentation (section 3. "Setting up the sy...
[VERSION]: MCSDK 6.4.1[TOOL]:6-Step FirmwareControl by MC Pilot[DETAILS]:In open loop mode, the same duty causes a big speed difference between CW and CCW.It doesn’t make sense.[EXPECTED BEHAVIOR]:In open loop control, CW and CCW should not have a bi...
[PN]: STM32G431CBU6[VERSION]: 6.4.1[TOOL]: Motor Control Workbench[DETAILS]:The automatic calculation for the speed observer gains in the Speed Sensing Config and the speed regulator gains (Kp & Ki) in the Drive Settings fails. This occurs after impo...
Hi Sir, The peak current of the B-G431B-ESC1 is 40A. Is it possible to modify the board to achieve a higher peak current? If yes, what modifications would be required? If not, could you explain the limitations?Thank you.
Hello everyone,I'm facing an issue with my BLDC motor control system configured via MC Workbench and operated using ST Motor Pilot.Here is my setup:STM32F303FOC with Hall sensorsCurrent sensing with 3 shuntsPWM at 20kHzMotor current limit: 20A, nomin...
I have a strange problem with the ADC/TIM interrupts for a simple FOC motor application on STM32G431 on the B-B431B-ESC eval board. The build uses FreeRTOS.There appears to be some strange behavior with R3_2_TIMx_UP_IRQHandler() and ADC1_2_IRQHandler...
