STM32 MCUs Motor control

Hello,I created a new project by using the STM32 Motor Control Software Development Kit (version 6.4.1). The project code was generated. I need a CAD of the project circuit to connect all the hardware parts. Could you please specify how to generate a CAD of the circuit? Thank you. 

Hi everyone,I’d like to learn more about FOC algorithms and eventually design my own motor driver. For this purpose, I’m planning to use the STEVAL-CTM009V1 to drive a pump or traction motor similar to those used in forklifts.In general, forklifts with around 2-ton lifting capacity are based on a 48V architecture, and I already have access to such a system for testing.My main question is:Can I drive an ACIM (induction motor) with the STEVAL-CTM009V1? I’m not fully sure about its capabilities in this regard. If it is possible, are there any reference projects or examples that I can follow?Also, when using Motor Control Workbench, which control board would you recommend pairing with the STEVAL-CTM009V1?I should also mention that I’m already familiar with FOC concepts and have experience designing forklifts and telehandlers, but this will be my first time designing a motor driver from scratch, so I’d really appreciate any guidance or best practices.Thanks in advance for your help!

I'm using an STM32G431 and MCSDK 6.4.1. It's a 340 VDC BLDC motor with two pairs of magnets, running in FOC mode with HAL sensors. The motor works well most of the time, but it often starts in the wrong direction and then returns to the correct direction after a few revolutions. This happens when trying to move forward or backward. Sometimes the motor goes into "hard commutation"—the current is higher at about half the normal current, and a sound indicates that the rotation isn't as smooth as usual. I tried adjusting the HALL_PHASE_SHIFT setting in 15-degree increments and settled on the smoothest rotation in both directions. Debugging the HAL sensors showed stable sector readings in both directions and no interference in these signals.What else can I try to make rotations reliable? Would an oscilloscope help?

Hi everyone! I am developing a custom inverter+control board and need to use motor pilot. Would someone please tell that apart from enabling UART TX and RX through Motor Control Workbench and wiring them, what additional hardware do I need for isolated connection to a PC?Thanks and Regards

Hi all,I noticed that when using the encoder, the motor undergoes an alignment phase during which it completes a rotation until it reaches the position where the Index Z signal is triggered.I was wondering if it's possible to skip this alignment phase by adding the Hall sensors (like with the B-G473E combined with the STEVAL-LVLP01 board), and if so, what should I specify in the Workbench or in the Code?Regards,Jules

Hello. Could someone please recommend a good power board that can power and control two gimbal 3-phase BLDC 12V motors with encoders AS5048A https://www.sparkfun.com/gimbal-motor-with-encoder-12v-587rpm.html ? I use the STM32 NUCLEO-64 F401RE microcontroller board. Thank you.

I am currently working with MC Workbench and the ST Motor Pilot tool for motor control development. While setting up and attempting to establish a connection using the latest version of ST Motor Pilot, I am encountering a connection issue that appears to be caused by a bug in the current release.As suggested in the community forums, I also tried using an older version of ST Motor Pilot. However, this introduces dependency conflicts, as other required components and tools in the workflow depend on the latest versions and are not fully compatible with the older Motor Pilot version.Board- STEVAL-ESC001V1  

Hi everyone,I'm using an STM32H723 for a project with Hall sensor encoders on two BLDC motors.**Hardware:**- Left motor: PE7, PE8, PE9 (U,V,W)- Right motor: PD3, PD4, PD2 (U,V,W)**Problem:**Right motor encoder works perfectly. Left motor has issues:1. Tick count is much lower than right motor (82 vs 236 ticks for same movement)**Debug Output:*ENC:0,1|DIR:STOP,CW ← Left STOP, Right movingENC:6,11|DIR:CW,CW ← Both OK brieflyENC:8,21|DIR:STOP,CW ← Left STOP againENC:82,236|DIR:CW,CW ← Huge tick difference**What I've Tried:**- Added debouncing- Removed direction reset on invalid transitions- Verified signals on oscilloscope (clean)- External pull-ups (4.7kΩ)**Key Difference:**- Right motor: Dedicated EXTI2, EXTI3, EXTI4 handlers → WORKS- Left motor: Shared EXTI9_5_IRQHandler for all 3 pins → PROBLEMS**Questions:**1. Can shared EXTI9_5_IRQHandler cause missed transitions when two pins change simultaneously?2. Should I move left motor to pins with dedicated EXTI lines (0-4)?3. Is there any w

Hello,   Is there any resource or reference available like tutorial video or presentations to set up a minimal working configuration for the IPM30B? I have experience on a low power setup with X-NUCLEO-IHM16M1  but I am new to hardware assemblying with ST and I am trying to understand how to correctly configure a basic setup to make the motor start. My goal is to have a minimal working system, including: - IPM30B power stage - G431RB or G474RE development board, with the suitable motor control connector and with flat cable - Two separate low voltage DC supplies (one for auxilliary 15V port and the other one for Vdc bus)  - Low power PMSM with 24V nominal voltage  - Basic configuration using Motor Control Workbench / MCSDK for PMSM sensorless basic operation   At the moment, I am not sure about the correct jumper connections required to match the configuration settings in ST Motor Control Workbench, the proper wiring details between the IPM30

Hi there,Im trying to get my STEVAL-PTOOL1V1 up and running with my motor, a Sofasco sDBS7025 with the following specs:3-phase BLDC7-12V DC operating voltage1.5A rated current11100 max RPM 4 pole 8 pins:PinFunction1V2W3U4HW5HU6HV75V08COMI have managed to get it operating by using the STEVAL-PTOOL1V1_6S_HL example project in the ST Motor Control SDK V 6.4.1 however I seem to have little control over the speed.I haven't been using the potentiometer feature of the STEVAL-PTOOL1V1 and instead been using the following functions:MC_ProgramSpeedRampMotor1(2000, 1000);MC_StartMotor1();and when wanting to change the speed, changing the 2000 for a different speed and rebuilding the project and programming to the board.However when I input a different speed e.g. 10000 there is no difference to the speed, observed by the current draw of the bench power supply remaining the same. I suspect I have setup the motor parameters incorrectly in the MC Workbench 6-step wizard but am not

Hi,I’m experiencing a consistent issue with the STM32 Motor Control SDK:The first motor start attempt always fails with a MC_SPEED_FDBK faultAfter acknowledging the fault, the second (or further) start attempts work perfectly Observations:During the first start, there is no audible motor movementCurrent signals (I_q_ref / I_q_meas) look misaligned or not properly regulatedAfter the first failed attempt, signals stabilize and the motor starts normallyThe MC state is initially IDLEFault reported: 0x0020 (MC_SPEED_FDBK)Observations:During the first start, there is no audible motor movementCurrent signals (I_q_ref / I_q_meas) look misaligned or not properly regulatedAfter the first failed attempt, signals stabilize and the motor starts normallyThe MC state is initially IDLEFault reported: 0x0020 (MC_SPEED_FDBK)It seems like something is not fully initialized/calibrated on the first start, possibly:Current sensing / ADC offset calibration My Setup:SW in Release ModeTarget: Custom

Hi,We are working for a project on Railway application, where we have selected STM32G4A1VET6 controller for Motor control application.we are developing custom board for Motor control application, Selected motor is BG65x50 dCore by Dunker motor,above selected controller is not available in MC workbench software. Could you please provide solution on this one and also the motor control library package is not available in STM32CUBE IDE middleware section.

Hello, I want to test my FOC algorithm on my hardware, so I designed my own PCB based on the evaluation board of STSPIN32G4, and create an empty project in STM32CubeIDE. I use a voltage regulator to output 12V to my PCB. And I When I was testing the internal driver of STSPIN32G4, I found a problem that whatever I do the voltage of GHS was 5.8v and the voltage of GLS is 0v. I have already tried to let PE8 high level or gnd or a PWM, but the voltage of GHS1 never change. And even I do nothing, just downlowd an empty program to STSPIN32G4, the voltage of three GHS are 5.8v. If I run the empty program, the nFAULT will be high, and if I use the combined output with timer 1 turned on, the nFAULT will be low.I think the waveform of GHS should be consistent with INH, the waveform of GLS should be consistent with INL. So the voltage of GHS and GLS won't be a fixed value. Is my idea correct? How do I know if the internal driver of STSPIN32G4 is working properly

Dear community,I'm developing the STSPIN32G4. My setup is as follows:12V for the V_MExternal 3.3V for VDD / VDDA / VREF+ / VBAT / VREGINPB8 (BOOT0) with 10K pull-downnRESET with RC-delay circuit: 10K pull-up to 3.3V + 10uF capacitorPower sequence: 12V is applied first to the STSPIN32G4 and L6982N33DR, then L6982N33DR supplies 3.3V to VDDThe problem I'm facing right now is:The MCU starts working (sending UART and running the peripheral devices), but the gate control parts (GHSx & GLSx) remain idle and don’t drive current.I have to manually pull nRESET low again to start the gate control.How can I solve this? I want the chip to automatically start the gate driver at power-up.I also noticed that the EVSPIN32G4 evaluation board shows the same behavior.

[PN]: STSPIN32G4[VERSION]: v6.4.1[TOOL]: MC Workbench / Motor Pilot[DETAILS]:I am working with a custom PCB design which was largely follows the EVSPIN32G4 schematic. I defined a custom board in MC Workbench and generated firmware, and can upload the firmware to the STSPIN without issue. Motor Pilot detects the board, and I can command START/STOP and read values/status.When I press START for either Torque or Speed control, the board enters some ALIGNMENT stage (only the first time) followed by RUN. No behavior is observed with the motor. No faults are ever reported by Motor Pilot. I can STOP and START motor control again and still see no change in behavior.With a scope, after START I see a single pulse on the U phase's gate for around 22 microseconds, then it falls to 0V and remains there. I did briefly run the firmware under GDB, and I see that MOE is set during RUN.Using a 48V frameless motor, running from a Li-Ion pack (bus voltage currently 56V), SIR680LDP-T1-RE3 FETs. VCC mea

Hello, i found a bug in the code generated by the Motor Control Workbench usign the 6-step algorithm. Even with Open Loop mode enabled, the code is still using the PID for the initial duty cycle computation (state CHARGE_BOOT_CAP in the TSK_MediumFrequencyTaskM1()). If the PID isn't set up right and starts with a low duty cycle, the motor won't turn. This means the Hall sensors don't trigger, the duty cycle never updating, and the motor just sits there even if you set a high duty cycle value. The Open Loop mode shall bypass the PID controller, otherwise it is useless.  I fixed it by changing row 174 of mc_tasks_sixstep.c as follows: from:  MCI_ExecBufferedCommands(&Mci[M1]); /* Exec the speed ramp after changing of the speed sensor */ to: if (SDC_GetOpenLoopFlag(pOLS[M1])) { SDC_SetControlMode(pSDC[M1], MCM_DUTY_MODE); } else { MCI_ExecBufferedCommands(&Mci[M1]); /* Exec the speed ramp after changing of the speed sensor */ } Leo Edited to apply source code formatti

Hi i am getting this error while opening motor pilot for gui in motor control,pls go throgh below attached file.        

I recently built a motion-control setup using an STM32 MCU to drive a NEMA 23 stepper via a DM542 driver. STM32 timers reliably generate step pulses while DMA reduces CPU load, enabling smooth microstepping and precise speed control. Key tips: match driver current to motor specs, use a 24–48V stiff supply, keep motor and logic wiring separate, and provide cooling for the driver. Implement trapezoidal acceleration to avoid missed steps and add homing/limit switches for safety. For multi-axis systems, synchronize timers or use an RTOS for higher-level planning. Happy to share sample timer code or a parts list on request.

Hi,I am using STM32G0 with STM32 Motor Control SDK. ADC1 is used for motor current sensing (triggered by TIM1 for FOC control).Since STM32G0 has only one ADC and does not support injected channels, I needed to read an additional NTC sensor (ADC channel 8) for motor stator temperature.I implemented this using Regular Conversion Manager (RCM):Registered ADC channel using RCM_RegisterRegConv()Requested conversion periodically (~300 ms)Read the value after conversion completionThe motor is running stable, and I am able to get temperature readings without visible disturbance.My question:Is this a correct and recommended approach for reading an additional analog signal in STM32G0 + MCSDK?Are there any potential risks (timing issues, FOC accuracy impact) when using RCM alongside motor control?Or is there a better recommended method for this use case (e.g., external ADC, different MCU, or MCSDK-specific approach)?Thank you.

when i run my .stmcx file in stmcsdk 5.4.8v i am getting these type of errors ,how can resolve  

I am using the EVLSPIN32G0B1 demo board and the MC Workbench v6.4.1 software, and I would like to use the FOC control algorithm.More specifically, I would like to use the Hall sensors when the motor starts and operates at low speeds, and then switch to sensorless control at higher speeds.I have read that the library does not support automatic switching, so I will need to implement it manually in the code.How should I proceed?Thank you for your support.
