STM32 MCUs Motor control

I used MotorControl Workbench_6.4.1 and used the Board designer to generate the simplest design for the sixStep inverter design.I choose STM32030K as the MCU and assigned back emf as the speed and position control and also configured the Phase voltage generation and M1 specification and every thing gets a green check mark. then I tried to build a project with the created inverter board file and when I select to generate the project, the MotorControl Workbench Just shows a blank screen and nothing happens. what's going on wrong?I have attached the inverted json file to the post.

Hello ST Community,I am designing a FOC motor controller using STM32G4 and want to use 3 separate ADCs (ADC1, ADC2, ADC3) in injected mode for simultaneous 3-phase current sampling.I know that some microcontrollers have triple-mode ADCs, which allow all three ADCs to start and finish simultaneously. My question is:1. When TIM1_TRGO is triggered, do all three ADCs start converting simultaneously, or is there a sequential order (ADC1→ADC2→ADC3)?2. What is the safest way to read an ADC for FOC algorithm?I am very new to this field, so please excuse me.Best regards

Dear member of ST community, I would ask you about the thermal characteristics of B-G431-ESC1 Motor Control evaluation board.I purchased it few weeks ago and started to play with six step for beginning and later FOC algorithms. I observed on my board that if power supply V+ 18-20V is active and PWM outputs are switching, of course deadtime is set to ~500ns, board running at 170MHz the PCB temperature reaches  ~50 °C or even more. The temperature is quite uniform. The DC/DC itself produces heat by switching and the power stage too, but for me seems to be a little to much. Is it normal or something is failed on the board? I removed the DC/DC converter and provided the 10V from external supply, the situation is similar.

Can X-NUCLEO-IHM09M2 (adapter board) connect with NUCLEO-H755ZI-Q (controller board) using male and female connector(without flying wire)? 

I am working on a project to drive a door using a PMSM motor in position control mode.When I change the shunt resistor value in the Current Detection step of MCW, the overcurrent protection threshold remains fixed (7A) and does not update accordingly.When the shunt resistance value is modified, isn’t the overcurrent protection threshold expected to update too?Screenshots are attached.Thanks in advance for your help. Details:ST MCW Ver            : 6.4.0STM32CubeIDE Ver : 1.19.0Driving algorithm       : FOCControl board            : Nucleo-G474REPower board              : STEVAL-IHM023V3Bridge                        : X-NUCLEO-IHM09M2

I am a new user looking to configure the STEVAL-IPM30B evaluation board to drive a three phase dc motor.  I am uncertain which of the many STM32 boards I require.  Also, what type of cable is needed to connect the two boards?  My application requirements are basic on and off control of the motor at different speeds with open loop operation (I am using a three phase stepping motor).  

Hello everyone,I want to understand to clear my mind about regenerative brake MC library. I dont have ossiloscope.Assume P-NUCLEO IHM03. I am using it with different motor with HALL sensors with load. in speed control -> MC_ProgramSpeedRampMotor1_F(targetspeed, rampduration);   TO MC_ProgramSpeedRampMotor1_F(0, rampduration);Now we get energy from Motor to Battery, right?But because of no control of this energy, if Voltage is too high then can gives damage the battery.1-let me know. Can MC library observe the Voltage and if it is too high direct it to Motor coils to consume like low side pwm turn on( as much as I know in this case entire energy consumed in motor), or we gonna do it manual, if it manual how we gonna do that(function name?)  2- assume we have high power resistor parallel to VBus(as much as I know this resistor connect like that ?), In this case ,how we gonna direct the current

Hello,I am controlling my motor with the Hall effect sensor first. I am not using any auxiliary sensor. I am able to control my motor correctly, and I can visualize the angle from the Hall sensor. I need to evaluate the number of turns the motor makes and be able to reset this counter to zero at the start. Thank you.

I'm learning BLDC control using the EVSPIN32G06Q1S1 and MCSDK 6.4. The inner current loop is implemented in hardware. The current feedback goes to an op-amp PI controller (I think?),then is compared with a reference voltage.The reference voltage level depends on the TIM17 PWM duty cycle.The comparison result goes to TIM1 ETR. There is no documentation for this. I need a manual or design guide for selecting the capacitor and resistor values in the PI controller.  I found

Hi,While I'm creating custom inverter board for 3 Phase BLDC motor Rail application. I had configured all motor related parameter, while Current sensing section, I have chosen Three Shunt Raw Currents Differential External Gain.I'm getting this error.Pin connection Details:

Hi,i have a new EVLSERVO1 and a STLINK-V3SET ant try to program my MSDK 6.4.0 generated firmware but i am not able to connect to the bord.  I use the latest STMCubeProgrammer 2 20.0 and the latest stsw-link009 USB Driver.I updated the Firmware on the V3 to the latest version. And i tried both variants of the firmware.   The Software recognizes the V3 Hardware and reads the 3.3 Volt from the ELSERVO1 board.i tried to use a Win10 and a win 11 machine.  But I am not able to connect or to flash the Board.The 14 pin cable to the board seams to be ok. I am able to connect and flash other STM Boards with this setup like the STM32H745I-DISCO. Is there anything I have to set to achieve a connection?I also tried the UART1 connection with Tera Term without success.Do I have to send the Bootloader activation patterns 15? &n

hi,I have set ICL configurations in the MC workbench, but the generated project doesn't include "inrush_current_limiter.h" , "inrush_current_limiter.c" and any related calls, just some ICL parameters macro.

Hi, I designed a custom inverter, based on G473VE, external amplifier and compare, use TIM8 to generate PWM wave, use IR2101S to drive MOSFET. When I try to profile the motor(based on HSO), I get the error: ERROR_DC_AC. I have upload the screenshot(90e0d582f6e2fb5d5043ff325aab241.png), stwb6 file(MCV1_HSO_PROFILE.rar) and schematic files(MC_V1.pdf). Could you help me please? Thanks a lot!I have tried frequency from 20hz to 100hz, and power from 2w to 5w. but no use...

Hello,I've useX-CUBE-MCSDK v6.4.1B-G473E-ZEST1S + STEVAL-LVLP01 + B-MOTOR-PMSMA1with the HSO.I can make it run with the GUI. But can't start the motor with API.In the legacy, I use MC_ProgramSpeedRampMotor1(100, 1000); for 600 rpm within 1000 ms.For HSO, I can't find the same API, but found that may need to use these:MC_SetAccelerationMotor1()MC_SetSpeedReferenceMotor1()The question is how to calculate the value passing to these API, I found it different from the legacy. Thank you.

I am working with the EVSPIN32G06Q1S3 and the STLINK-V3SET, I have the two programmer/debugger boards mounted on top of each other. Then I have the UART connector connected to the EVSPIN32G06Q1S3 (J5) and the programmer/debugger boards (CN7). I have 230 VAC going into the EVSPIN board. The lights on both the STLINK and the EVSPIN turned on. Device manager recognizes the LINK, but I can't detect the EVSPIN in Motor Pilot or STM32CubeIDE. I've tried the "Discover Board" option in Motor pilot and manually changing the baud rate to each option with no results. I think it might be a firmware issue, but I'm not entirely sure. 

Hi,I have downloaded the firmware into the board and when I hit the start button on Motor Pilot, the motor starts up and runs perfectly with the correct slope, but it seems the motor goes past my set speed and then errors with a Over Current status.Any ideas would be appreciated.regards,Charles

I have manually migrated from MCSDK 6.2.0 to 6.4.0 for my micro STM32G431RBT6 from the example project as i have seen several changes in the source code and HAL drivers and i want to keep the project upto date for any future changes and can adapt easily, i have finished porting but I am confused with Regular conversion manager component, i am getting the ADC values only in the High frequency Task when PWM is ON, using the functions  RCM_ReadOngoingConv(); RCM_ExecNextConv(); But i want the values when PWM is OFF or motor is n

[PN]: STSPIN32G4[VERSION]: 6.4.0[TOOL]: Motor Control Workbench[DETAILS]:In this design, the second motor does not work as the interrupts that invoke the FOC_HighFrequencyTask by setting the motor ID into the array FOC_array[] are not enabled (TSK_DualDriveFIFOUpdate() is never called). Motor 1 happens to work as it's ID is 0 and the array is 0 initialised. Also the task TSK_HighFrequencyTask is only invoked at the PWM rate, not twice the PWM rate as it should be called once per motor, ie twice the PWM rate..[EXPECTED BEHAVIOR]: The motor 2 current should be modulated but stays at 0 as the FOC_HighFrequencyTask(M2) is never called.[

 Why are the motor parameters of the compressor analyzed by Motor Pilot_6.4.0 so different from those described in the compressor specification?The attachments are a screenshot of the analysis results from Pilot and the compressor specification.If I have any misunderstandings, please help me to correct them. for example,Polot get:Ls 7.21mH, Inertia 108.8spec. of compressor:15.6mH , 230 

[PN]: EVLSERVO1[VERSION]: 6.4.0[TOOL]: MC Workbench[DETAILS]:Issue 1After enabling Flux Weakening, I can achieve higher motor speeds; however, under a constant load the speed sometimes swings dramatically. My observation suggests that the control firmware is repeatedly switching between flux-weakening and base-speed modes, creating abrupt transitions.Issue 2With both Flux Weakening and Over-Modulation enabled, attempting to increase the motor speed causes the controller to keep raising the Iq reference instead of decreasing the Id reference. This prevents further acceleration and result

Hello Everybody,I have a high-power BLDC motor with a rated power of 200W and a nominal voltage of 24V, resulting in a current draw of approximately 10A. I intend to use Motor Profiler to detect detailed motor parameters (e.g., B-EMF constant). Could you advise on which ST control board is suitable? I know there are many control boards like NUCLEO-G431RB. Given the high current, is the control board with the Three-Shunt current sensing inappropriate? If so, what alternative control board should I select? Thank you!

Hello ST Community,I am currently working on a motor control project using an STM32 microcontroller and STM32CubeIDE. I have noticed that the code size (firmware image size) is larger than expected, and I would like to reduce it as much as possible to fit within memory constraints and improve performance.Are there recommended methods or best practices to optimize the firmware code and reduce its size? At present, the firmware size is: 

hello,I am a student, and for my university project, we are using this stepper motor controller X-NUCLEO-IHM05A1, and I have the STM32NucleoF401RE Microcontroller board to send the command to the motor control. I see there is one middleware package for this motor controller called X-CUBE-SPN5. So, I try to search for this middleware package on STM32CubeIDE, but there is no option regarding it. Now I go to the ST website and I am looking for the .zip file, but there is nothing. I also try to find the proper use case, how can I install, and how can I use but is there any documentation available for that? So can you please provide me this package so I can control the motor easily for my university project, and if possible, so guidance on how i install this middleware package into STM32CubeIDE and how to use this middleware package function for controling the motor. I am waiting for your reply.
