STM32 MCUs Motor control

Hello,We are using STM32 Motor Profiler to identify the parameters of an IPMSM motor, but the profiling process always stops at approximately 7% and reports a “Driver Protection” fault.Hardware configuration: - MCU board: NUCLEO-F446RE - Motor-control expansion board: X-NUCLEO-IHM09M2 - Power board: STEVAL-IPMM15B -Motor type: IPMSM  Thank you. 

In position control mode, when the commanded angleand motion time are not properly matched, the motor speed sometimes exceeds the maximum speed limit. For example, if the motor’s maximum speed is 3000 RPM, after executing the command the motor speed may reach 4000 RPM. Its not generating error that this motion cannot be executed.

I’m starting FOC code generation for H5 using MCSDKBlocks I am configuring in MC Workbench include , STMH563ZI (Nucleo Bd) and IHM07M1 (Power module), and motor.  I noticed the PWM configuration is not for general purpose, it is specifically configured for L6230 in IMH07M1.But I’d like to configure PWM for general purpose,  such as for the STEVAL-LVLP01 board I have evaluated already, is this possible? Please let me know and thank you for your consideration.

Hello ST Community,I am working on a BLDC motor control project and would like to use STM32 Motor Control SDK (MCSDK) Workbench to generate firmware.My Hardware ConfigurationMotor Type: BLDCMotor Voltage: 48VMCU: STM32F405RGT6IssueWhen creating a new project in MCSDK Workbench, I cannot find my exact board/MCU configuration in the board selection list. Since the STM32F405RGT6 board is not available in the predefined options, I am unable to proceed with the standard project generation workflow.QuestionsIs STM32F405RGT6 officially supported by MCSDK Workbench?If yes, how can I create a project for this MCU when it is not listed in the board selection menu?Is there a way to add a custom board definition?Where can I obtain the required board configuration/JSON file (if available)?Can an existing board configuration be modified to support STM32F405RGT6?If MCSDK does support this MCU, what is the recommended procedure for configuring:PWM generationCurrent sensingHall sensors / Sensorless con

I reviewed the code and found anti-windup is not implemented in the loop, is that correct?  Let me know if there is a version with anti-windup implemented, thank you.

I am Having a 2.2 Kwatt PMSM motor i have created a custom power Board, I am using STM32F303Re nucleo board .I am using 2hall sensors for current feed back . my motor starts but does not reach the final full rpm. my power board schematic is attached herewith the powerboard is working correctly, why does the motor not attain the maximum speed. my motor parameters are correct, also i am not able to vary the speed of the motor while running application .from the oscilloscope waveforms it looks like the when the speed tries to increase the feedback drops and motor goes out of sync momentarily. the oscilloscope waveform frequency drops and the FOC again tries to catch the rotor , this keeps on happening and then after some time the motor goes into speed feedback. i am not using Motorpilot, i am running openloop in MCSDK and calling the start motor function from my code after speed ramp function .

Hi everyone,I'm working with the STM32F446RE and exploring the 6-step BLDC motor control example provided by the STM32 Motor Control SDK. In the CubeMX configuration of the firmware:3 GPIOs are configured as analog inputs:M1_BEMF_U → PC3 → ADC1_IN13M1_BEMF_V → PA7 → ADC1_IN7M1_BEMF_W → PB0 → ADC1_IN8However, in the ADC Injected Conversion Mode, only Channel 13 (PC3) is selected and used (1 injected conversion configured).See image below for reference:My question is:Why are all 3 BEMF pins configured in CubeMX if only Channel 13 is used in the ADC injected group?I expected that all 3 channels would be used in the injected sequence to sample U, V, and W BEMF voltages.Do they dynamically change the injected channel in code depending on the commutation step? Or is there another reason for this configuration?Thanks in advance for any clarification!

We are using the EVSPIN32F06Q1S1 board and have configured TIM1 PWM outputs as CH1/CH1N → PA8/PA7, CH2/CH2N → PA9/PB0, and CH3/CH3N → PA10/PB1. While probing the board, we observed PWM waveforms at test points TP1, TP2, and TP3, which according to the documentation are connected to RES1, RES2, and RES3 rather than to PA8, PA9, and PA10. The complementary outputs are also present and behaving as expected at their respective MCU pins. Could you please clarify how the TIM1 PWM signals are being routed to TP1–TP3 and whether RES1–RES3 are internally connected to the TIM1 outputs on this board?

hello guys i hope you’re doing good,I have a problem while using a Nucleo board STM32F446 with the IHM08M1 driver and a BLDC motor.The issue is that I'm trying to use MATLAB to configure it, and it didn't work. I don't know if the gate driver is necessary to make it work, or maybe the logic (the logic to configure or run the BLDC motor) is not correct. Please, do you have any idea to help us? Can someone tell us how to make it work? i'm really stuck

I am new to this evaluation boad can someone please help me to configure this board. is there any separate ide for this other than cube ide?

Hi,I would like to ask whether support for the STM32C5 family is planned in the STM32 Motor Control SDK (MC-SDK).If so, could you please provide an indication of the expected release timeframe or roadmap for its integration?We are currently evaluating STM32 devices for a motor control application and would like to understand whether STM32C5 family will be officially supported by the MC-SDK in the near future.Thank you in advance for your support.Best Regards

Hi everyone,I am new to the MCSDK environment and currently working on a porting project from MCSDK 5.4.8 to 6.4.1. I have been stuck on this for weeks and I am honestly getting desperate as I cannot find a way forward.I need a functional routine to handle encoder alignment that is compatible with the 6.4.1 framework. The alignment must be performed solely upon user request, and it is critical that the motor does not start running after the alignment sequence. I am looking for a direct replacement for the legacy MCAlignEncoderMotor1() API.I have already attempted the implementation suggested in this thread: MCSDK 6.3 - Correct way to restart / retrigger encoder alignmentUnfortunately, this solution does not work for my setup. Could you please provide guidance on how to trigger this alignment in isolation within the 6.4.1 architecture?Best regards,bolla_bo

Hi ST community,We are evaluating motor-control architecture for a 3-phase BLDC/PMSM ESC project based on STM32G431 / STSPIN32G4.Currently we understand that STM32 MCSDK supports both:- FOC control projects- 6-step / trapezoidal control projectsHowever, we would like to clarify whether MCSDK officially supports runtime switch-over from 6-step control to FOC control in the same firmware project.Our target concept is:1. Start the motor with 6-step control or open-loop 6-step startup.2. After the motor reaches a sufficient speed / stable rotor position estimation, switch to FOC control.3. Continue running with FOC current loop and SVPWM.Questions:1. Does MCSDK officially support runtime switch-over from 6-step control to FOC control in one generated project?2. If not officially supported, is there any ST reference implementation, application note, or recommended method for implementing this handover?3. Can MCSDK-generated 6-step and FOC control modules coexist in one runtime while sharing

I started with the MC workbench and installed X-Cube-MCSDK Version 6.4.2. After installation the MC Workbench is opened, but the dialog is complete empty (except the caption). The behaviour is the same if i start the workbench via the desktop icon or as administrator.

After creating the project from Workbench, I discovered that pins PA14 and PA13 in CubeMX were not working. I checked the Workbench settings again but couldn't find any parameters related to this issue. Without these pins, the motor cannot communicate. I also tried manually configuring them and the motor worked, but I think the Workbench setup would be better.Schematic of B-G431B-ESC1 discovery kitCube MX  

I have been developing an application based on the STEVAL-PTOOL1V1_6S_HL. I have managed to successfully get the motor up and running to the expected RPM using the speed potentiometer functionality. I am now developing my own custom hardware using the STSPIN32F0B and I will not be using the speed potentiometer to control the speed of the motor. Instead my intention is to use the commands such as:MC_ProgramSpeedRampMotor1(2000, 1000);MC_StartMotor1();To set the motor speed and start the motor.I am unsure of how to go about removing the speed potentiometer functionality from the generated code In MC Workbench (V6.4.2) after loading in the STEVAL-PTOOL1V1_6S_HL.ioc the Potentiometer option visible can’t be changed 

I have written a code to control two Hall sensor based geared BLDC Motors. I am using DRV-8353rs motor driver for this. We have designed a custom pcb as our motor control board. I have attached a pdf showing the circuit connection which we are following. I am also attaching the relevant code files needed to analyse this as well as a couple of tests I have run till now. I am generating pwm for motor 1 via Tim 1 and motor 2 via Tim 8 ( using complimentary pwm generation from 3 channels i,e CH1 CH1n CH2 CH2N CH3 CH3N). There are mainly two concerns which I am unable to resolve right now. 1. The motor running on tim 8 is always faster than the motor on tim1. The difference is smaller at lower duty cycles and increases along with it. 2. When running in reverse, the current consumption is approximately 1.5 that of what it draws when running in the clockwise. I am an amateur in this domain, and most of my work has been heavily dependent on chatGPT and Claude.
