STM32 MCUs Motor control

Hello Team,     We want to run BLDC motor using  STEVAL-SPIN3204, As per user guide initially we started with motor control work bench 6.3 version.  while creating new project  selecting driving algorithm as FOC and selecting the motor type but in inverter section STEVAL-SPIN3204 this board is not available , it is available when we select driving algorithm as 6 step. As per product specification on STM website it says it support both FOC and six step.for reference refer below snapshot. kindly confirm can this board be used as in FOC and six step mode. Is that motor control work bench is not supported FOC for this board.     

Hi,I want to evluate STM32G473 based MCU for driving BLDC motor. Can you suggest a development kit which has:- STM32G47 MCU- High Voltage motor driver circuit upto 600 V (like in EVSPIN32F0251S1) 

Hello Team,   we try to run the motor using motor control work bench, STM mx and STM cube IDE. motor run for 3 to 5 sec and stop.Is there any tutorial or any document or example we can follow step by step and understand each parameter related to STEVAL-SPIN3204?

Hi Community,does anybody know how to restart the encoder alignment process after the first initial alignent during motor startup ? EAC_SetRestartState(&EncAlignCtrlM1, true);EAC_StartAlignment(&EncAlignCtrlM1);while(MC_GetSTMStateMotor1() == ALIGNMENT){} seems not to do the trick.

Hi, I'm currently using Motor Workbench 6.2.1 and I'm trying to create a new project with a custom power board. To that end, I want to create the JSON descriptor file of the board.I have read the "Motor Control Boards description format" manual from ST Wiki, where it describes the version 3 of the format; however looking at some JSON files from other existing boards I've notice that the current version on them is version 4.For example, for the board STEVAL-LVLP01{"type": "power","name": "STEVAL-LVLP01","descVersion": 4,"contentVersion": "1.0","PN": "STEVAL-LVLP01","longDescription": "Three-phase brushless DC motor driver expansion board based on STSPIN830 for STM32 Nucleo","shortDescription": "PMSM & BLDC power board based on STSPIN830 for STM32 Nucleo","link": "https://www.st.com/en/ecosystems/x-nucleo-ihm16m1.html",......{"name": "PhaseVoltageSensing","type": "PhaseVoltageSensing","hwVariants": [{"type": "ThreePhaseVoltageDividersFiltered","help": "How to enable this variant

Hi,I am prototyping a custom PCB with integrated ESC for a BLDC Motor (Datasheet attached). For this purpose, I plan of using STSPIN32F0 due to versatile options following this article. The article's design is based on 45A max consumption and looking at BLDC's datasheet this seems appropriate. In addition to this, I would like to add following capabilities i.e. Control/ Info through BLE along with BLE DFU.Please recommend/ suggest, any ST's SiP supporting BLE or war around to accomplish the sample. Regards

Hello,I'm trying to do position control using EVSPIN32G4 board and pmsm motor with incremental encoder. I followed the steps given in AN5464. The motor did not move and the rotor is locked. I'm attaching the code here. **********************************************************************************************************/* USER CODE BEGIN 2 */MC_StartMotor1();/* USER CODE END 2 *//* Infinite loop *//* USER CODE BEGIN WHILE */while(MC_GetAlignmentStatusMotor1()!=TC_ALIGNMENT_COMPLETED){}while (1){/* USER CODE END WHILE *//* USER CODE BEGIN 3 */MC_ProgramPositionCommandMotor1(3.14/2,0.1);HAL_Delay(2000);MC_ProgramPositionCommandMotor1(-3.14/2,0.1);HAL_Delay(2000);}/* USER CODE END 3 */***********************************************************************************************************While debugging the code stops at "while(MC_GetAlignmentStatusMotor1()!=TC_ALIGNMENT_COMPLETED){}".

I'm building a motor for position control with a command rate ~10 Hz.  I'm using MCSDK 6.2.1 with a 6-step algorithm and Hall sensors.  The motor has a gear drive ratio ~400:1.  The output shaft has a rotary encoder for position.  I use the standard STM libraries for motor speed control and then manually implement position control based on encoder data.  The problem is that the motor has to start/stop with almost every position command, and startup is unreliable.  On other projects using FOC I've found using a motor hold at 0 rpm helps - while the hold is not strong it makes the startup cleaner.  However the 6-step libraries do not support the hold at 0 rpm function.  Is there way to access this hold function in the 6-step libraries?  Or some other method for improved startup function?  Thanks in advance.

Hello,I am considering transitioning to the ST MCU family for my inverter projects. The primary type of motor I use is ACIM. From what I have read, the latest version of the MCSDK/MotorControl Workbench only supports ACIM through two examples, and it is not possible to load my own type of motor and use it with a custom board. Is this correct?Additionally, I noticed in another post that there are plans to “add full support for the ACIM algorithm in September 2024.” @cedric H  Is this timeline still accurate? Is there any additional information or alternative solutions available?Thank you.  

Hi,We are working with B-G431B-ESC1 motor control board and have performed the motor profiling in ST MC Workbench 6.1.2 and it finished successfully, reaching 100% completeness. The problem:When trying to run the motor in motor pilot, the power supply (6S-battery) is connected and no drive commands are given, the motor keeps "ticking" in a consistent manner. About every 0.5 seconds or so.We have not figured out why this could be, and the plan is to monitor the MCU and the motor driver I/O to see what is giving the "drive pulses". We are supposed to drive the motor with a PWM signal.We installed STM32CubeMonitor software, and are trying to follow the instructions given in this post:Solved: Setting up variables - STMicroelectronics Community The plan is to monitor all of the GPIO ports in the Pull-up/ Pull-down Register (PUPDR) of the MCU, to get a clear picture of what is actually happening at that level. Our understanding is that we need to create variables in CubeMonito

Hello Team,   we try to run the motor using motor control work bench, STM mx and STM cube IDE. motor run for 3 to 5 sec and stop.Is there any tutorial or any document or example we can follow step by step and understand each parameter related to STEVAL-SPIN3202 and STEVAL-SPIN3204

Hello, We are trying to run 4 installations of these B-G431B-ESC1 motor control boards, and have faced some technical challenges.This is a very bare-bones test-setup to get the installation and programming workflow worked out. In a nutshell:A new board fresh out of the package, works when connected via STLINK-V2 and opened in STM32CubeProgrammer.We can install the Firmware file (B-G431B-ESC1#B-G431B-ESC1 3Sh#(6.1.2).hex)We can open the MotorControl Workbench and configure a project, then Generate the Project, open the project in STM32CubeIDE and finally run and debug the configuration. Seems to work as intended. The problems start when we solder the peripherals onto the board.. How delicate is the board to heat transfer while soldering? We have "practiced" 2 boards, so they fell victim to erroneus handling and incorrect soldering technique. Third board we have installed peripherals to, we checked the following:The board was found via STLINK-V2 in STM32 STLINK U

Hello everyone! I use a BLDC with hall sensors drivered by ST's B-G431B-ESC1 inverter board, and demo code generated by MC Workbench. Use ST Motor pilot V1.2.5 - MC_FOC_SDK have a test, BLDC is runing and everything is ok. In the demo code, TIM4 use OC2REF trgo, and TIM1 is set in Trigger Mode and Trigger Source is ITR1. I have checked STM32G4 series User Reference Manual which named RM0440 from v.7 to v.8, it is show that TIM1's trigger source ITR1 is internal connected to tim2_trgo. Wow, I'm confused! Once i modified the demo code from <TIM1.InputTrigger = TIM_TS_ITR1 > to <TIM1.InputTrigger = TIM_TS_ITR3 > as RM0440 described, PC software ST Motor pilot V1.2.5 - MC_FOC_SDK can not connect inverter board, so that BLDC can not run. I really need your help.Thank you so much! photos down are demo code configuration.        

hello sirI am using motor control workbench 5.4.6 and EVSPIN32F0602S3 kit. Is there any function to get individual phase ( R,Y,B) current and total average power of motor ?

I am using Nucleo-F401RE as controller and motor expansion board IHM02A1for powering 2 stepper motors. Additionally I added ADXL_345 sensor( accelerometer ) to control motors orientation and speed. Normally IHM02A1 requires 2 SPI's for communication, I had used third SPI for ADXL_345 and run the code, no errors found but motors were not working, no data was received from the sensor. I am sharing the file link over here  https://drive.google.com/drive/folders/1JAG42UiNA7D1bFZ8id9Gq7AeD2lQlGes?usp=sharing . Any advice you could share would be greatly appreciated.

Hi,I can't manage to get my motor to work with the EVLDRIVE101-HPD board. I have generated the FOC firmware and uploaded it to the board through STM32CubeIDE. See attached for main.cIs there something else I need to do? I have followed everything in the user manual for the board, but it is quite minimal in it's instructions.I have done all of these steps."To start your project with the board:1. Connect the brushless motor phases to J1, J2, and J32. Supply the board through J5 (positive) and J6 (ground)3. Download the compiled code through the SWD interface connecting the STLINK programmer to J7(STDC14 connector)"After these steps, the board is powered up but there is no PWM signal on the phases. It is a constant 0V. Any help will be appreciated, Thanks! 

#define OVM_VREF_MODE1_START ((int32_t)29717) #define OVM_VREF_MODE2_START ((int32_t)31186)The ratio between these two value is not sqrt(3)/2. What is the voltage unit used in these calculation? Or when a have a Valpha equal to 32767, what is the truth voltage in real world? Thanks.

Good Afternoon,Hope you are doing well. Looking for advise on how to resolve this issue.We designed a motor controller using the STL220N6F7 (MOSFET) and L6387ED gate driver. We know the MOSFETs are rated for 60V. However, when we ran 42V the MOSFETs started to smoke up. Can you please review the attached schematic and advise if you notice anything wrong. The motor controller works great at 24-29V. Only at higher voltages we see it heating up a lot. I included one of the three Gate-MOSFETs pair for reference. Let me know if you need anything else.Would it because of R33 and C44 by chance? I have tried referencing some of ST's motor controllers and except for the B-G431-ESC1, none of them uses these resisters on the output. Interestingly, the B-G431-ESC1 is also rated for 24 V. Unfortunately, I'm not sure what is the purpose of R33 and C44 in the first place.Any help is appreciated.

Hi!I have an I-PMSM motor and interfaces an incremental encoder with A B ,without Z.Sometimes after doing encoder alignment，the motor runs reverse to the max speed,and it will never recover until i do encoder alignment again。I set the speed 30RPM,but when start ,the motor goes to -200+RPM.Most time the motor runs well but sometimes the problem will happen.（STM32 F303VCT6 ；PWM16000KHZ ；Main Sensor ：Incremental Encoder2048 no Z-index）I hope someone could help me figure out the problem.Best wishes.

Hello Team,   we are using  STEVAL-SPIN3204 board to run our BLDC motor. As per guidance given STM32 motor control software we are getting error while generating code , below is snapshot for same. we have install all latest version of STM cube IDE,motor control work bench and STM cube MX. please guide us how to solve below problem.due to below error the code is not generated. 

I have crated a start project for the B-G431B-ESC1 using MC Workbench 6.3.0I used the following settings:Motor 'Bull Running BR2804-1700kV' and Inverter 'B-G431B-ESC1' the project User Interface show ON for 'Over USART A' at 115200 baud.I can build code and debug using onboard STLINK but cannot connect to start the motor using Motor Pilot. The COM port is detected and Motor Pilot tries various speeds but no connection.How can I fix this?

I just started testing the Motor Control API ,such as the ones below for initializing the motor control MC_ProgramSpeedRampMotor1(0, 0); MC_StartMotor1();Followed by this command which gets executed every 10 seconds. if (speed>0){ // sets a given speed to the motor MC_ProgramSpeedRampMotor1_F(speed*20, 0); HAL_Delay(100); } else{ // stops the motor MC_ProgramSpeedRampMotor1_F(0, 100); HAL_Delay(100); }While the commands work and are able to control the motor. I'm noticing a lag of several seconds between when the target speed is set and when the motor actually starts moving. Please see the video below for reference. You can see how the "Speed Reference" moves first followed by several seconds of delay before the motor starts moving.Any idea as to what maybe causing it and how I can get rid of that delay?
