STM32 MCUs Motor control

Greetings,The motor I am working on is low inductant ~0.1mH with a max speed of ~2500rpm. I am wrestling with noise on the measured phase current signals, which distorts the control loop and in the end results in bad control or 'Over Current' Fault. Currently I am testing on the IHM08M1 board in sensorless mode, in order to see if I can pin-point the source of the noise. The noise is both present when driving the motor in closed loop and open loop (at high rpm). I have made som measurements of the noise on the open loop rev-up. Internal signals extracted using UART(if I try to plot the control signals as well UART communication crashes, I have plotted them along side and they look like pure harmonic signals, except for when there are large transients on the current input signals)Internal SignalsPhase Current Signals (measured using current clamp):Ch1: I_A, Ch2: I_BPhase Current Measurements (using current clamp) These transients on the internal current reading are a

I want to control the speed of an AC motor with STM32, using pin PA6 on the MCU as an external interrupt, and PA7 as PWM.in the interrupt configuration I selected rising/falling edges and nopull up nopull down.on the code I have looked for various sources that I can learn from but it still doesn't work.here is my code: /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes -------------------

I am essentially experiencing the exact same issue as this poster.  I have a single conversion registered, on ADC1 channel 13. It works great for ages, and then the RCM_execRegularConv function gets "stuck" waiting for end of conversion.   I am running MC workbench 6.1.2 - unlike the poster in the link, I did not declare the handle on the stack, and it does not appear to be getting corrupted - I can stop the program and see that the reference to the ADC is still intact.  I am trying to reproduce again, so I can look at the registers on the ADC that reflect the state of conversion, but this really is a *rare* issue, so it's difficult to reproduce it quickly for testing. -R 

Hi,Im currently tring to program my nucleo-f103rb module. I have succesfully generated Motor control workbench project and CubeMx project. After code generation using cubemx , stm32cubeide1.8.0 opens the project code. Without changing anyting on the code , i pressed debug and 17 errors accured. I will share build console respons below.Build console:17:41:05 **** Incremental Build of configuration Debug for project stm32f103rb_son ****make -j8 all arm-none-eabi-gcc "../MotorControl/App/motorcontrol.c" -mcpu=cortex-m3 -std=gnu11 -g3 -DDEBUG -DUSE_HAL_DRIVER -DSTM32F103xB -c -I../MotorControl/App -I../MotorControl -I../Core/Inc -I../Drivers/STM32F1xx_HAL_Driver/Inc -I../Drivers/STM32F1xx_HAL_Driver/Inc/Legacy -I../MCSDK_v5.4.8-Full/MotorControl/MCSDK/MCLib/Any/Inc -I../MCSDK_v5.4.8-Full/MotorControl/MCSDK/MCLib/F1xx/Inc -I../MCSDK_v5.4.8-Full/MotorControl/MCSDK/UILibrary/Inc -I../MCSDK_v5.4.8-Full/MotorControl/MCSDK/SystemDriveParams -I../Drivers/CMSIS/Device/ST/STM32F1xx/Include -I../Dri

I am trying to identify the motor parameters of a BLDC (with a multipolar magnet rotor) using Motor Profiler. Should I select SM-PMSM or I-PMSM in magnetic built-in?Thank you in advance for your answer. King regards,Cristhian Chavez Thank you in advance for your answer. King regards,Cristhian Chavez 

Good day sir, i want to ask about pwm duty cycle sir. I have a coustem board with input 220vac, after dioda rectifier become 310v, but my motor only aceptable 200v. So how to control duty cycle of the pwm on HIN and LIN input sir? So i want used only 60-70% of duty cycle, so the output avarage i getting around 190-210v sir. Iam not see on the mc worckbench, only see the pwm frequency sir. Thank u somuch:folded_hands:. Or do u have any ide of this?? Or must be use transfomator?? Because i see ac servo drive without transfomator. Only input ac220v with dioda rectifier sir. Thank u:folded_hands:Iam using  board stm32 g341. And i used internal opamp. I will used 3shunt, but i see only 2 opamp are use. Opamp1&2, and also only 2 output are use. So how about 1 more output?? It not using sir?? I see on mcworckbench dokumentation also same, e see schematic of stm b g431 esc1 same also only 2 outpur are use. Three sunt on lowside. Image are present.   

I have enabled the Discontinuous pwm and ran the motor but it started rotating in reverse direction compared to when none is enable. With no Discontinuous mode all features are validated, now i want to test all of them with Discontinuous mode enabled. Do i need to make any other changes?  

Hi,It's already really frustrating & time consuming to get help from ST.They ask you to create support tickets.They say we can't help you if you are not specific.To be more specific, I tried adding comments to the already created ticket and I keep getting this error : FeedComment_trigger: execution of AfterInsert caused by: System.DmlException: Update failed. First exception on row 0 with id 500Ty000003bZ0NIAU; first error: FIELD_FILTER_VALIDATION_EXCEPTION, Value does not exist or does not match filter criteria(MKT_RPN).: [Mkt_RPN__c] Class.FeedUtility.SendCommentFeedByMail: line 1146, column 1 Class.FeedUtility.HandleNewCommentCaseFeed: line 203, column 1 Trigger.FeedComment_trigger: line 54, column 1Has anyone seen this?Or should I make a new ticket with the additional details? 

Hi, I am new to ST evaluation board. I am trying to connect STEVAL-SPIN3204 board to a windows 10, and it is not working.In more details: The board is working with stsw-link007 (ST-LinkUpgrade) and loads the recent driver version (V2J43M28). The USB connects to Windows as Drive D with details.txt file.I loaded en.stsw-link009 drivers (64 bits) and updated the com port (STMicroelectronics STLink Virtual COM Port (COM3)) driver to version 2.2.0.0 dated 4/1/2021. The COM port hardware Ids are USB\VID_0483PID_374B&REV_000&MI_02 and USB\VID_0483PID_374B&MI_02.The COM port is configured for 115200 baud, 8 bits, not parity, 1 stop bit.However, when it is connected to the ST Motor Pilot V.1.2.5 that came with Motor Pilot 6.2.1 - it is not working and the board remains disconnected. Discover Board fails with the following message:[INFO] - : Application is starting : MotorPilot version:1.2.5[INFO] - : ini file path=C:/Users/Ran/AppData/Roaming/ST Microelectronics/

Can anyone explain to me how to calculate the "gain" property for a "NTCThermistor" hardware variant?The NTCs we use (NTCS0805E3103FMT) are not linear, so a "Thermistor gain in mV/°C" as mentioned in the wiki doesn't apply.As a side note: The wiki says the property should be named "ntcThermistorGain" but inside the board configuration json this name is invalid and it is simply named "gain" instead.

Hi! I am developing a project with a BLDC motor. It is possible to use Motor Profiler with a BLDC motor. The options only allow me to use Motor Profiler with PMSM. Thank you in advance!

To whom it may concern, I am developing a controller for BLDC, I managed to initialize the board with cubeIDE and flash code (so far only turning on the LED). However, I need to use a BLDC motor for my project and I have searched everywhere on how to initialize and do a motor profiler, etc. But there is no information about how it works, just that it doesn't. Could you please provide information on how to set up the 6-step controller with b-g431b-esc1 and which software should be used, since so far none of your released software works.  This is the BLDC motor I am using: https://maytech.cn/products/mto5065-170-ha-c Any help would be appreciated. Sincerely,Mykolas

Hello.Our goal is to create a medical motor control program used to cut bones.For this purpose, I am using the EVSPIN32G4 example from MCSDK 6.2.1.(This is a custom board that uses a Hall sensor, and the circuit is the same as the EVSPIN32G4 board.) case1.It was confirmed that the motor operates on the FOC algorithm, but the torque is very weak at low speeds.I'm trying several methods, but I can't get the results I want. case2.I wanted to test a different algorithm, so I changed the algorithm from FOC to 6Step, but the Current Sensing item is not activated in MC Workbench.The board is the same, but I don't know why it can't be activated.When testing in this state, the motor does not operate. I would really appreciate any ideas or help on these issues.Regards

Dear all,I am using the STM32 Nucleo pack with a F302R8 card, the IHM07M1 and the associated motor.The library for motor control (6Step_Lib.c) of  X-CUBE-SPN7 only provides a few functions, for ex MC_StartMotor, MC_StopMotor() and MC_Set_Speed().I would thus be interested to know how to control the motor given a specific angle as input : it seems that only using theses 3 functions won't be precise enough : for example if we use MC_Set_Speed() to set the speed at w degree per second, and if we want a rotation of theta degree, rotate the motor (at speed w) for theta/w second won't enable to target a precise angle.Thanks for your help & time ! :)

Hello, Please I need a help, I'm using the MC workbench and after saving the project and reach to generate the project it's giving this error that the MX is not found or I need to install a verison more the 6.0. bytheway I already installed the latest version but the problem is not solved.Please if it's possible to provide me with any feedback how it's possible to solve this issue.

This is the first time I have to implement a PMDC motor control system.There are 3-phase sine currents need to be converted into d-q components using Clark and Park.I don't have the motor to test yet, so with the DAC I created three 120° phase-shifted sine waves that I need to convert into d-q components. This is an example of the code I wrote:My questions are:1) Is this code sufficient for conversion?2) Is there an implementable library that performs these calculations? I found only this, but it is not clear to me what it can doCan anyone, in general, give me some more information on how to proceed?

I have the P-Nucleo-IHM03, I'm trying to use Motor Pilot V1.1.5 and it will not connect. The STLink works just fine when using CubeProgrammer

Hello Everyone,I would like to use STM32F373xx series. However I noticed  in the datasheet, they don't specify  PWM generation with "edge or center-aligned modes" with full modulation capability (0-100%)?Is this MCU  can generate PWM with center-aligned mode and can I use It for motor control application ?Need your help!Regards,

[VERSION]: 6.2.1[TOOL]: MC WB, Board Manager[DETAILS]: I'm working with a custom board using an STSPIN32G4. Can the LPUART on the STSPIN32G4 be used for the MCP (Motion Control Protocol)? When I try assigning the pins for the LPUART (PB10 and PC1) to UART_RX  and UART_TX in the Board Manager, and then create a project in the MC Workbench, I get an error, "Sorry, the selected hardware doesn't support this feature." If I use one of the USARTs then I don't get this error. I'd like to know if it's possible to use the LPUART for this purpose in the firmware.Board Manager:MC WB:  

Hi GuysI'm just a newbie who got into stm32 architecture and i want to develop a BLDC controller for a Flycat 5010 360kv BLDC motor the power supply is 24v and the max current rating i want is 60A can anyone recommend me a schematic a application note to hook up the MCU and Recommend a mosfet to handle the above mentioned spec any help would be appreciated.Thank youKavin kumar

Good morningI am in the process of building another CNC milling machine. For the two largest stepper motors , I would like to use X-Nucleo-IHM03A1 drivers connected to the Stm32 board. I initially looked at the capabilities of IHM03A1 and batch files for Stm32CubeIDE.I have a question:Can IHM03A1 be controlled via Stm32 board from an external motion controller , for example by providing an external PULSE signal to the STCK pin ?Thank you in advance

Hello, I do have a problem running STM32 Motor Control Workbench 6.2.1 . The UI doesn't load at all. even running with admin rights and installed using admin rights as well   I have downloaded Microsoft Visual C++ Redistributable Version 14.38.33135.0Also updated the to .NET Framework 3.5 and NVidia Graphics card as well still doesn't work I am using Windows 10 Education NVersion 10.0.19045 Build 19045I feel that I am missing something here. But, I don't know what 

Hi allI have some problem using the Break interrupts (BK1 and BK2). When activated it keeps firing the break interrupt handler: TIM1_BRK_IRQHandlerWe have measured the BK1 and BK2 signals and the states are as they scould be when activayted/deactivated and there are no noise on the lines.The BK1 and BK2 is setup in the Timer1 with correct polarity etc.The PWM's are stopped when activated, but the interrupts handler keeps getting called!Did I miss something in the handler?   void TIM1_BRK_IRQHandler(void) { // Reset Master Output Enable on motor timer - aka Coast htim1.Instance->BDTR &= ~(TIM_BDTR_MOE); htim1.Instance->SR &= ~(TIM_SR_BIF); Beef::Pal::Stm32h7xx::MotorIsr::ExecuteBreakInterruptHandler(); HAL_TIM_IRQHandler(&htim1); }   It is a STM32H730Any idea what causijng this or is it just the way Break inputs are working?I could disable interrupts in the handler and reactivate it when starting the PWM again`? Thomasa
