STM32 MCUs Motor control

I made customized board based on bg431besc1 board all pin defined are  same as original board except I did not placed back emf register . it working well just like original board in Arduino in both open loop as well as closed loop with very smooth speed. But when I ran it in stm32ide it did not run but it  debugging and show  zero fault zero speed . the code i m using is same code earlier i used for original board  both Arduino and stm32ide codes and motor is also same. so tell me what is problem also motor pilot it connect when i upload ide closed loop code when connect by usb but when i on power 24v it show try to configure with show correct port nd connected board. this is my code   

Hello,I am trying to get my STM32G4B1C3 ESC working for a brushless rc hobbyist motor with unknown motor parameters. I flashed a generic set of parameters to the device and enabled the motor profiler before flashing so that I could estimate them online.  When I connect to the motor pilot app Everything is detected fine with no faults, but then I click begin profiler and it seems to just stall with a high pitch noise and never gets past 7% complete. I have tried swapping the 3 phases in all combinations with no change in behavior: Motor details:Aerosky MC2212-980KV 7 pole pairs with standard surface magnets (outboard) 

Hello,We are currently developing a drone using B-G431B-ESC1 motor control boards, and we have encountered stability issues during flight testing.Components Used.Radiolink Flight ControllerReadytosky 920KV BLDC Motors3S LiPo Battery1045 PropellersWe characterized the motors using Motor Profiler firmware generated with Motor Control SDK v6.3.0. The resulting motor JSON file was used to generate the ESC firmware for testing.After assembling and configuring the drone, we observed that the drone is not stable during flight.To address an issue related to motor ramp-up during startup, we modified the PID integral term initialization in the mc_tasks_foc.c file. Specifically, we replaced:PID_SetIntegralTerm(&PIDSpeedHandle_M1, (((int32_t)FOCVars[M1].Iqdref.q * (int16_t)PID_GetKIDivisor(&PIDSpeedHandle_M1)) / PID_SPEED_INTEGRAL_INIT_DIV));with:PID_SetIntegralTerm(&PIDSpeedHandle_M1, 2); This was done in an attempt to eliminate the motor ramp-up to max RPM in the initi

hello, can anybody tell me as we know bg431besc1 is 48 pin MSU so if i want to customize a board of 64 based on bg431besc1 how we can select edit and all things can be done with stm32cubeMX cuz we know board selection is pre fix in workbench as well as in motor prophiler  bg431besc1 (inverter board) ur help will save my time . 

Hi,I am using a Stepper motor and the motor driver IC used is STSPIN220. I have to measure the torque of the motor to find when it has reached maximum load. What is the best way to do it?

Hello, I use STM32CubeIDE to compile the motor control code. The code runs without problem, when in normal run modes.  To use SWV trace for debug, I do the following:1) complie for debug2) start debug by "Resume"3) stop debug by "Suspend"4) reset the uC by the black button 5) open Motor Pilot and build the connection6) start the motor in speed or torque control mode. And the motor runs as expected. The three phase currents are monitored with current probe. The waves are symetrical and ok.7) keep the Motor Pilot running and the motor running and change to CubeIDE 8) click th red button "Start Trace" in SWV without restart debug by "Resume". Noise is obtained in the measured phase current, even when nothing is tracked, because still not resumed. And the noise disapears clicking on "Start Trace", the red button.Can you understand the noise issue in this case? How to use SWV in parallel to Motor Pilot? Thanks for your support. STM32User

Hi I am currently trying to convert a  project for the STM32 Motor Workbench by creating a custom inverter board. However when trying to create the workbench project by connecting the motor to my custom board I either get a current sensing error or the board doesnt even appear because it is not correctly configured. The project was first realised in PLECS and because of the reduced number of ADC for the phases U and V the ADC4 Channel 1 and 2 are used but for the third phase the second channel of ADC2 is used. I dont know if this could be an issue. I added the error file, an image of the error and the custom board file to this post. The custom board file still has some values that are the correct values for later as I am just trying to get the custom board to work with the workbench software, but I correctly configured the pins. I would be really happy if someone could help me.Kind RegardsElias 

Hi, from the update it looks like current sensing mode can now be enabled on 6 steps, but from the MC workbench it still looks disabled. attached to confirm it's the mc workbench 6.4.0 - see attached imagesi selected EVSPIN32G4NH which has stspin32g4 + evspin32g4

I want to design a robust and safe Back-EMF sensing system that:Can safely interface high voltage (~50V or ~80V in 12S/20S) phase lines to MCU GPIO/ADC.Still al

Dear Support team,I am currently working on a sensorless motor control application using the Observer + PLL algorithm to run a 24V PMSM motor (rated at 3600 RPM, no load) on a custom driver board based on the STM32F030R8. My PWM frequency is 8000kHz and I am using a single shunt resistor for current sensing.The motor appears to operate correctly during the ramp-up phase. However, it stops immediately after transitioning to closed-loop FOC, triggering a startup failure error.I am using STM32 Motor Control Workbench version 5.4.8 for configuration. I have attached the wb file and .stmcx file in .txt format containing the full GUI-based configurations for your reference.I would appreciate your assistance in resolving this issue.

Hello everyone,I'm currently working on driving a 24V, 1.5A BLDC motor using a Nucleo-F070RB board along with the X-NUCLEO-IHM16M1 motor driver shield. For testing purposes, I'm running the motor in open-loop mode.I've configured Timer 1 to generate PWM with complementary signals. However, when I check the outputs with an oscilloscope, I don’t see any PWM signal. Additionally, the status LEDs (D8, D9, D10) on the driver board are not lighting up.I've attached the connection diagram below for reference.Has anyone faced a similar issue or have suggestions on what might be going wrong? Any help would be greatly appreciated!Thanks in advance!  

 I use MCSDK6.3.2 to generate code, when use TIM1 to generate pwm wave, everything is ok. But, when I use TIM8 to generate pwm wave, the code is still TIM1, which is fixed in the code, not according to the pwmc_handle. What is wrong?  Is this a bug?

Hi, I have a project in the MC workbench and I can generate code (for stm32F407) successfully when I use the "Three Shunt Resistors" current reading topology, and the code works well on my board. Now I need to change my board and use the current sensors. So I change the current reading topology in my project to "Two insulated current sensors". However, when I try to generate the code, the error "Neither embedded nor external opamps selected for current sensing for motor M1" appears. But I can't find any configuration on this issue in the project settings, could you please tell me how can I fix the problem? Thanks a lot.

Dear support team,I am currently working on a bldc motor control project using the stm32 workbench. Because I am writing my bachelor thesis I need some background information on how the entire foc model behind the configurator is actually build. I assume that it has the same structure as other FOC projects with parke clarke transformation etc.. However I also need information on the observers that can be configured. Are there any papers that where used to program the observers? I would be really thankful if you could provide me with such information.Additionally is there any option to test the models in simulation  for example in SimulinkKind RegardsEH
