STM32 MCUs Motor control

I am using  STM32H7A3 for speed control of BLDC hub motor, I also need to take the feedback speed from the driver using stm32 timer input capture mode or external clock source, I have doubt for choosing, Please any help to figure out this.....

Hi,I have a clean, freshly generated project using the MC Workbench. Normally I can compile the code and flash both cores, and it works fine after I power cycle the board (with other nucleo-64 boards I don't need to reset the board). But when I tried to debug it stuck on LL_ADC_IsCalibrationOnGoing. I've switched ADC mux from PLL2P to PLL3R without success but then I tried to switch to PER_CK and it goes through ADC calibration. I found that PLL clocks are initialized by CM7 core but whole logic runs at CM4 core. I've tried multiple debug configs but might be issue there since I'm not an expert :D Default Access port 3 - Cortex-M4 doesn't work and I've need to switch to 0 - Cortex-M7. When using 3 - Cortex-M4 it catches SIGTRAPSince App runs normally, I can use ST Motor Pilot and spin motors I assume there is something wrong with my debug configurationSetup belowHW:Power Board NUCLEO-

Hello,I am using the STEAVL-PTOOL4A to drive a BLDC motor using the FOC with hall sensors. The motor is running ok but I noticed that during the start of the motor, the speed does not reach its final value at the same time. I mean there is a noticed difference. Sometimes it is slow, sometimes it is fast. I increase the bootstrap Capacitor time from 10ms to 1000ms I still have some differences but lower when I had 10ms.  Here are some plots when the speed reaches its target fast And here when it is slow:

Hi, [PN]: B-G431B-ESC1[VERSION]: MCSDK 6.3.0[TOOL]: STM32CubeIDE 1.16.1, MotorControl Workbench 6.3.0[DETAILS]:I am designing a custom motor controller based on the B-G431B-ESC1 board. I have modified the power stage and current sensing hardware to support higher current and voltage ratings (targeting 100A and 100V). I am using MCSDK-generated firmware with FOC (Field-Oriented Control). However, I am having difficulty identifying which sections of the firmware or configuration files handle the over-current and over-voltage protection thresholds.[EXPECTED BEHAVIOUR]:Update the firmware so that the current, voltage, and protection ratings match my modified hardware specifications (100A

Reason: No device found on target.  I  dont understand the problem can someone help me , i used jumpers on J7 and J8  and still the problem presists how can i fix it ! , this is my first time using such a board and it is still  new 

Hi all ,I’m currently using the EVSPIN32G development board to run six-step trapezoidal commutation.I’m using Motor Pilot version V1.2.12 with the MC_6STEP GUI.In the ST Motor Control tutorial under '6-step - Optimization and troubleshooting of sensor-less firmware parameters,' I saw several phase voltage (BEMF U/V/W) waveforms. However, in Motor Pilot I can only find 'bus voltage' and 'bemf_ADC_conf'—I don’t see any options related to viewing BEMF U/V/W voltages directly. Could you please advise how I can access these waveforms, or if there’s an additional setting or tool needed to display them?

I developed a board for 3 ph motor control with a quadrature encoder that seems to work fine. Now my client would like to modify it to use separate supplies for control/logic and motor as is standard practice in the PLC/automation world.There are a couple of ways of doing this (in order of preference):1) Power the STM32G431 die from the logic supply and the drive die and motor from the motor supply2) Power the STSPIN32G4 from the logic supply and the motor from the motor supply.3) Treat everything associated with the STSPIN32G4 and motor as a 'motor power domain' (not preferred)Thinking about approach #1:Figure 1 on page 3 of the data sheet is not super helpful.It shows VDD on both dies without a strong indication of how it gets from one to the other.Perhaps they are separate, one coming in on the VDD/VDDA pin of the left hand die and another one coming in on REG3V3/VDD of the right hand die because they are actually diffe

Hello,I am trying to get started with the EVSPIN32G4-DUAL but where can I find the Firmware or an example project for the Motor Control Workbench?Thank you!Quirin

I am working on a project to drive a door using a PMSM motor in position control mode. I am trying to add an emergency brake function. In an emergency, when the operator pushes a button, motor should brake and then return to its starting position without harming anyone.I know there is PWMC_TurnOnLowSides() function (https://community.st.com/t5/stm32-mcus-motor-control/how-can-i-stop-the-motor-urgently/m-p/597309#M8287 ). But it is just stopping the motor, not braking. I have tried this function.As far as I know, there is no such API in position control mode.If I am wrong, is there an API to brake the motor in an emergency? Can anyone help me? Do you have any advice for me?Any information you provide will be welcomed.   Project:ST MCW Ver    &n

Hi, I am trying to run a 400W Servo Moto

I am developing a PMSM motor controller using STM32F103C8T6. I want to check the variables on live expression while I am running the motor. But as soon as I increase the current draw of motor, the values on the live expression starts to show random values or blank fields. and in the console, it prints "Target is not responding, retrying...". Why might this be happening?I am having this issue on a custom PCB that I have built. I have made a similar PCB with bigger form factor and this issue is slightly lower in that PCB. What could be the causes of this issue? and what precautions should be taken to prevent this?

Dear STM Community,I am currently developing an elevator door control application using the EVSPIN32F0251S1 board with a PMSM/BLDC motor, and I am looking to implement an automatic calibration routine to adapt to varying door sizes at different installation sites.Since elevator doors can differ in width, the number of motor rotations required to fully open or close the door will not be consistent across all installations. Currently, this calibration is done manually by counting motor rotations, which is not scalable or efficient. I would like to ask if there is a recommended method or best practice for implementing auto-calibration of door travel using the Motor Control SDK or STM32 ecosystem. Ideally, the system should automatically detect the open and close limits during installation, store that data in non-volatile memory, and use it for normal operation.Do

Hi, I'm developing a FOC board based on STM32G431RBT6 and I wanted to test the board in open loop before attempting to FOC.While testing for current sensing, I'm getting a lot of noise which messes up the measurement.I tried disconnecting the motor to be sure that the source of the noise is not the SMPS on the board, there is little to no noise on the ADCs without the motor.It looks like this when running the motor in open loop with very low RPM. With increased RPM, the noise becomes more prominent since the motor is not under any load and drawing less current at the same power, and it becomes impossible even to

Hello everyone,I am working on a BLDC motor and have implemented Field-Oriented Control (FOC) on an STM32f103c86  microcontroller.

Hi.I am currently working on a custom board using the stspin32g4. This was derived from the evspin32g4 development board alone with the stm32 motor workbench. Uploading the motor workbench code to the evspin32g4, works and can tune the motor parameters through serial.Moving away from the development evspin32g4 to a custom board has become a tad tricky. I am able to possible flash the custom board's stspin32g4 microcontroller using the ST-link/V2 programmer/ debug tool. However, I couldn't get the serial uart port working. I can confirm the source code is exactly the same (Being uploaded) to the evspin32g4 (So I don't think it's a programming issue).At first, I tried confirming the UART is working correctly. I used the SFR in the stm32 IDE debug tab and modified the registers (When it is in debug mode) (Register USART1 --> RDR (Checking byte sent from the computer serial port application matches the hex value present) and (Register USART1 --> TDR (Writing a

Hello. I am doing stepper motor step control. I am using the "HAL_TIM_PWM_PulseFinishedCallback" function for this operation. Is there a more functional usage method than this? I can't get the max torque of the motor. Can you help me? Motor Driver "TB6600" / Step Motor "Nema17"

Hello,I am currently working with a custom board using an STGIB15CH60TS-LZ driver and an STM32H503RBT6 microcontroller.The motor is a 48V, 500W, 300 RPM brushless motor with three Hall effect sensors (120° mechanical angle, 300° electrical angle). It is used in an electric bike.I am using the FOC algorithm with:Single shunt resistor16k PWM generationHall sensors as the main sensorEverything works correctly, but I sometimes have an issue at startup and under load. Once the motor is running, the issue does not occur.The image shows the three Hall effect sensors during a failed startup. In this case, the issue comes from the C2 signal.I believe the problem is caused by small movements in the opposite direction of the expected motor rotation for the FOC algorithm. The motor controller returns a "speed feedback" error.I am looking for a solution to prevent this error in the FOC algorithm since the revers

Hello, I'm working with the ST EVAL3201 motor controller board. I'd like to use an STM32 Discovery board to send commands to start and stop the motor. Is this feasible? If so, could you provide guidance on the necessary connections and communication protocols?

hi, I have been trying to run PMSM motors with B-G431B-ESC1, I follow the steps given in the user manual, 1. I profile the motor and save the parameters 2. use the motor control workbench to generate a project, and generate source code, 3. run it in Cube IDE to flash it on the development board. However, I am unable to run my motor with that source code. The motor doesn't even start. I also face inconsistency when running the motor with the same source code on different occasions. What could be the issue, and what should I do to resolve this issue? since the profiler is working, where can I get a profiler code based on which the profiling .hex file is created to debug the issue? Thank you, Madhav

Hello everyone,We constantly receive orders from our customers that they got some motors which their nominal speed, nominal voltage, and etc. are approximately similar to each other, but their Rs, Ls, Ke, and pole pairs may differ.They want us to design an inverter board in such a way that it can get these motors running, providing the capability to see if their motors are damaged or not, just by using a single board without the need to customize the firmware or the hardware for each motor. So, we need to somehow get pole pairs of the motor from the user, change it in the firmware and run the profiling process.For such purposes,What can we do by using ST motor control workbench?What are the related APIs to achieve this goal?Is this even possible?Thank you!
