STM32 MCUs Motor control

Hello, I’m working with an EVSPIN32G4 demo board and trying to get it running with a Bodine BLDC motor in a sensorless (hall-less) configuration. I’ve got firmware that appears to work initially, but after pressing RESET or cycling the 48 VDC power, I immediately get an “Over Current” fault in Motor Pilot. When I click “Acknowledge Faults” and then press “Start”, the Over Current error comes back right away. I’m still new to this platform, so I’m not sure what’s causing the issue. I’ve attached my Motor Workbench project and the motor datasheet — if someone could take a look and provide some guidance, I’d really appreciate it. Thanks in advance!

 picture tells all. the resolver says these two functions have conflicting IP settings but the settings themselves apparently not.

I am currently seeking to implement motor rotation control to any desired angle using the P-NUCLEO-IHM001 motor kit. Is this feasible? If so, how should I proceed? Are there any relevant tutorials or documentation available? Thank you. *This post has been translated from Chinese to comply with the ST Community guidelines.

I've gotten myself into an odd bug or something. I had been using the Motor Profiler successfully from the Workbench for a month or so and I had to stop for a while and work on other items. I may have played around the graphing/plotting stuff in Motor Profiler the last thing I did. Not totally sure. When I went through the normal connection process to run Motor Profiler today I got a weird pop up that only stays on for 2 seconds and then disappears. I'm not sure if I've ever seen this screen before. It could be a GUI. It could be settings for a plot, but it is not the Motor Profiler GUI that I expected. I captured the 2-second pop up from a video in the attached image. Does anyone know if this is a bug or corrupted files or settings. How do I reset Workbench to get it to just open the profiler GUI again? Thanks for any assistance you can provide.  

Hi. I used steval-ipm15b and nucleo-g431 to run a pmsm motor. when I see the current waves in the motor pilot or osciloscope, they are not sinus-shaped waves. can anyone help me what is the problem and what should I do?

Hi everybody!I started programming ARM microcontrollers after watching Mr. Patrick Hood-Daniels' tutorials on YouTube. I am using a Nucleo F334R8 development board to control a Puppet animatronic I am making for my niece. You can see it here:https://youtube.com/shorts/40tsBrCdnOg?si=NuuiD9RuRrL3VxnXI want to share the code I used with everyone, hope you find It useful // PUPPET head servos many positions#include "main.h"void SystemClock_Config(void);int main(void){int headServo;int neckServo;int handServo;int armServo;int pulsecounter;HAL_Init();SystemClock_Config();RCC->AHBENR |= RCC_AHBENR_GPIOCEN;RCC->AHBENR |= RCC_AHBENR_GPIODEN;GPIOD->MODER |=GPIO_MODER_MODER2_0;GPIOD->MODER &= ~(GPIO_MODER_MODER2_1);GPIOD->OTYPER &= ~(GPIO_OTYPER_OT_2);GPIOD->OSPEEDR |= GPIO_OSPEEDER_OSPEEDR2;GPIOD->PUPDR &= ~(GPIO_PUPDR_PUPDR2);GPIOC->MODER |= GPIO_MODER_MODER4_0;GPIOC->MODER &= ~(GPIO_MODER_MODER4_1);GPIOC->OTYPER &= ~(GPIO_OTYPER_OT_4

Hai All,   Got a STM32F446 & IHM08M1.   Planning to do the six step commutation using High/Low Method (without PWM), Hall Effect Sensor & Timer.   What are the precautions to be considered?    Any links..

Hi,I am working STSPIN32F0 and I have STVAL-SPIN3201 evaluation bord and install Motor Control WorkBench 6.4.1.When I try to generate project, it is given "STM32CubeMX not found - ver. "6.0.0" or higher is required" error but CubeIde 1.19.0 was install in my computer nevertheless I install cubemx 6.15.0 but problem to continue.How can solve this problem?

Hi, @Peter BENSCH . I am working on a project. In which i need to control Stepper motor using X-Nucleo-IHM01A1 Sheild. Currently i'm using STM32G431RB Nucleo-64 board for this and in future will use STM32F103. I've download X Cube SPN1 for basic working. But i think it does not support boards like (STM32G4 and STM32F103). How can i change X Cube SPN1 Library to make workable or any Solution for making L6474 to work with STM32F103 ?Moreover, I successfully run Stepper motor with STM32G431RB in Arduino IDE same version of this library.  Link of library is attached. https://github.com/stm32duino/X-NUCLEO-IHM01A1.  Thanks

Hi,When the start command is issued on the STEVAL SPIN3202, while in FOC mode, the board immediately falls into overcurrent protection mode. The voltage on the current sense resistor is captured in the attached oscilloscope image. The board is configured as follows: Header JP8: Pin 2-3 closed, FOC mode. Header J11 closed, Header J12 open.When overcurrent protection is turned off in the MotorControl Workbench, there is no PWM output.The motor is driven in sensorless mode, 30V DC, 10A max. When start is pressed, a short audible "click" can be heard from the motor, until overcurrent protection kicks in.I can provide more details when requested.Thanks, MaPi 

Greetings,I am very new to ST MCU development, but not new to embedded development. I've developed professionally on Microchip, Qorvo,,and Renesys for the last 20 years.  I am working on bringing up the kit in title. I was successful in generating compiled code for the ElectronicSpeedControl_ESC-G4 project in ST Motor Workbench 6.4. I am working with the latest tools from your website. I did use the stand alone Motor Profiler tool (v5.4) to run a profile on a drone motor successfully, but I quickly realized that it generated XML files for profiles. I figured out that the new version of MP was embedded in WB and produced JSON files. So I proceeded down that path. I could connect the kit to the newest version of MP, but it said I need a "Profiler" version of FW on my kit. I had downloaded the compiled non-Profiler version. This is where it went off the rails. When created a brand new project with the kit and a 24V motor selected from the default group of motors and I check

I'm currently encountering an issue with the P-NUCLEO-IHM001 motor. I'm using STM32Cube version 6.10 and X-CUBE-MCSDK version 5.4.8. During file generation, the problem shown in the image has arisen. How should I resolve this? *This post has been translated from Chinese to comply with the ST Community guidelines.

I want to use mcsdk v6 to run ac induction motor in open loop mode (V/F). how should I do it?

Hello ST community.Based on the content of this page, there should be ACIM example files for V/F and FOC motor drives, but after downloading both MCSDK 5.4.7 and 5.4.8, i found no ACIM example file for this topic in MC Workbecnch. Where shoud i get these files?Thank you for your time and support.

Hello ST Community,I am designing a residential pump driver product that requires a Variable Frequency Drive (VFD) to control a three-phase AC induction motor. I am using the STM32 Motor Control SDK as a reference, specifically the AC induction motor page.https://wiki.stmicroelectronics.cn/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motorMy goal is to find the most cost-effective STM32 MCU that can reliably implement this control. Is there a cheaper alternative to STM32G431RB? For example, can i use STM32F0 or G0 series?Also is there any other reliable solutions except for MCSDK which may lead to this goal, meaning a lower BOM cost?Is there any plan to add ACIM driver support in MCSDK V6.X in future?Thank you for your time and expertise.

[PN]: STM32G473CBUX[VERSION]: 6.4.1[TOOL]: Motor Control Workbench[DETAILS]:In this design, which I tried to setup exactly as my previous working projects, the ASPEP comms code seem to have setup interrupts to occur on UART Rx and not Tx and Rx DMA is not setting flags to allow comms in check in systick handler, line 227 in "stm32_mc_common_it.c".[EXPECTED BEHAVIOR]: On other projects setup (with eg STM32G431VBTX) in similar fashion, Tx interrupts occur in UART IRQ handler, DMA_TC flag is set for UART Rx.[HOW TO REPRODUCE]: Compile from MCW6.4.1 to Stm32CubeMx to STMCubeIDE and run on custom hardware, but maybe you can check some other way why Tx and Rx DMA and interrupts have gotten swapped in this code compared to previous projects.

Hello,I’m working on a motor control application using STM32 and configuring the project with MC Workbench.After generating the project, I manually customize the CubeMX (.ioc) file to adapt it to my hardware (e.g., adding peripherals, changing pin assignments, etc.).However, every time I regenerate the project from MC Workbench, my CubeMX modifications are overwritten, and I have to redo them manually.:backhand_index_pointing_right: My question:Is there a recommended way to:preserve custom CubeMX changes after regenerating from MC Workbench?or integrate these adjustments directly into MC Workbench so they are included during generation?Thanks in advance for your help!

Hello. I am trying to develop a BLDC motor driver. With Workbench, I can easily change the motor parameter. But whenever I change the motor, I should reconfigure and re-compile. So I would like to make a FW can change motor parameter dynamically. Is it possible with MCSDK? Thank you in advance. 

Hello Everybody,Here are the software and boards in this case:1. MC workbench 6.4.12. STM32 FW V1.28.2I’m using the generated code from ST MCSDK and noticed an issue on the microcontroller’s U-phase and V-phase channels (see pins Ch. U and Ch. V in picture 1; the same happens on W-phase, but I didn’t capture that waveform).The blue waveform never completes its falling edge where it should go low, so the whole period looks like a constant high (see picture 2).Is this behavior normal? If not, how can I fix it? Could it be related to the duty-cycle settings of PWM?My gate-driver chip already provides hardware dead-time, so I set the software dead-time to 0; the motor still spins.Thank you!

I am working on a 3ph motor control with EVSPIN32G4. I want to know how to measure motor speed through GPIO (To match with the measured quantities in motor pilot). Where can i find the details of that? 

I have multiple issues while driving the vehicle with the MCSDK software running. It is custom hardware MCSDK6.4.0Hall sensor based.1. Every time i start the vehicle at the beginning it jerks and then picks up, the behavior is not predictable, but jerking is always there some times more, less and hall fault etc. Now i have tested again on the bench and captured the waveform of the phase currentsThe first few steps before the sinusoidal phase currents is problematic, so if i count i get 3 jerks before the motor started running. Can i eliminate this? It always happens when i start. Does it have anything to do with hall placement angle. I have not run the Motor pilot as i don't have the setup for that. I can perform multiple iterations of trial and error for the placement angle if the above angle is a problem at present it is 30. And my forward movement and reverse does not have the same placement angle may be due to the motor design.Next major problem is intermittent speed feedback fault

Hello Everybody,Here are the software and boards in this case:1. MC workbench 6.4.12. STM32 FW V1.28.2I designed a project for my board, but the generated code has an error as illustrated in the picture, I didn't make any modification on the code and complie it directly after the generateion,How can I fix the problem??Thank you! 

We are currently working on a custom motor control project based on the STM32G431CBU6 microcontroller. Our goal is to implement 6-step BLDC motor control for an A2212/6T three-phase BLDC motor.We have already referred to the online documentation and tried the available firmware examples from GitHub. However, the firmware did not perform as expected — the motor only vibrates briefly instead of running properly. We also sent a query earlier and were advised to use the community forum, but we have not received any valuable technical guidance or working firmware support so far.To help your team understand our setup better, we have attached our schematics for both the microcontroller and GANFET boards.We kindly request your technical assistance or reference firmware for 6-step motor control using the STM32G431CBU6. Any internal documentation, configuration guidance, or tested example code would be extremely helpful for progressing with our project.Thank you for your time and support. We tru

Hi, Why is DAC_OVP_Threshold = 23830 ?  @GMA  Thx :) 

Hello,I’m working with the EVLSERVO1 board (STSPIN32G431) and using ST-LINK V3 + STM32CubeProgrammer.Connection: SWD (ST-LINK V3 to J1 header)CubeProgrammer connects and uploads HEX file successfullyBOOT0 = GNDNRST is wired correctlyAfter reset, MCU does not appear to execute my code (tested with simple LED blink and with motor-control firmware).I also tried “connect under reset” → programming OK, but still no execution.Questions:Is there a specific jumper or power setup required on EVLSERVO1 to run user code?Which GPIO pin controls the user LED (for a blink test)?Does ST provide a ready-to-use motor test firmware for EVLSERVO1 that I can flash to confirm hardware is OK?Could the problem be due to missing motor supply voltage (VM) even when only testing LED blink?
