STM32 MCUs Motor control

I'm using the BLDC motor dev kit (F302R8 + IHM07M1 + BR2804 motor).  When I run the Motor Pilot with the SimpleAppMCPV2 to tell the motor to go to a commanded speed, I keep getting a speed feedback fault.  Similar thing happens with the MC_FOC UI.  The motor starts turning, and runs up to 0.6 amps, then the fault happens and the motor stops turning.  I see the feedback speed is in the thousands of RPM instead of the 150RPM I commanded. I've read that the speed feedback fault might be due to needing to lower the cutoff frequency, so I lowered it from 6000 to 2000 rad/s.  But I still get the speed feedback fault.I'm not sure if there's something wrong with my current feedback config or speed feedback config?  This dev kit should be running in sensorless mode (no hall sensors for speed feedback), with FOC.Here's some of my settings.  I'm still new to this, so I don't have a good hunch on what I should be showing.  I'm guessing something is the

I'm using the Nucleo-F302R8 and the X-Nucleo-IHM07M1 with the small kit motor it comes with.  I'm having trouble getting the motor profiler to connect to the board.The F302R8 seems to have the demo motion program running, since I can hit the blue button to start the motor turning.  But if I want to run the profiler windows application and try to connect to the board, I get this error:"Port Open and try to configure the board"I've tried updating STLink, and it's on the latest (v2.j37.m26).  I've updated my USB driver.  I can connect to the board using ST-Link Utility.  But the motor profiler can't connect.What might be preventing motor profiler from connecting? 

Hello ST Community,I am currently using the EVSPIN32F0251S1 inverter board to control a BLDC motor in an elevator door control application.When I run my BLDC motor in torque mode and set torque with this api  MC_ProgramTorqueRampMotor1_F() so my motor is rapidly rotating and after 1 second it will give me startup failure error.Thank you in advance for your support. Best regards,Vedant Kachhadiya

For PID tuning, from documentation, I understood how to calculate gains for current loop. But how to calculate them for speed loop? How Motor control workbench is auto calculating the gains for speed regulator? Please provide documentation or formulas related to it. 

Hi Expert, I wan to use STM32303E-EVAL + STEVAL-IPM15B 3Sh to run the motor profiler 5.4.8.But the error message is shown below.I connect the control board to PC via USB, the LD8 is red. The device manager of PC cannot see com port. I think the STM32303E-EVAL not provide a virtual com port, right?How could I solve this problem?Thanks. 

I saw in a post here that someone blew up their B-G431B-ESC1 with just 5As using the motor profiler. The spec says the mosfets will output up to 120A. I am looking to run motors up to 30A. I'd like to see if there is a prescribed way of adding heat sink & fan to controller board. 

Hello,We are currently in the testing phase with the EVSPIN32G4 board using the various available software suites.After upgrading to the following latest versions:MC Workbench 6.3.2 → 6.4.0STM32CubeMX 6.??.? → 6.15.0STM32CubeG4 Firmware Package V1.6.0 → V1.6.1I created a project in MC Workbench for the EVSPIN32G4 board and generated the project for CubeMX.To my surprise, the microcontroller is no longer the correct one in CubeMX, even though it worked fine with the previous version.The evaluation board uses a 64-pin package, but the automatic configurator now selects a 100-pin package instead.I tried rolling back the software versions, but nothing seems to work: the package remains stuck on 100 pins.Do you have any idea what could be causing this issue?Thank you in advance.

I'm trying to program the EVSPIN32G06Q1S3 to run a PMSM, but I attempted to use STM32CubeMX to help with the pinouts and code. The problem is that I can't find the EVSPIN32G06Q1S3 in the board selector. Is there a way to download then import the board information to STM32CubeMX? If there's not, could I get documentation to help implement the board through the MCU selector? Thank you!

Hi, I'm working on a project in MC Workbench 6.3.2 and trying to configure a motor with a maximum speed of 150 RPM. When I set the "Max. Application Speed" parameter to 150 RPM (as shown in the first picture), I encounter an error related to the "Speed Sensing Configuration". I've attempted various parameter combinations for the Hall Sensor settings (as shown in the second picture), but haven't resolved the issue. Could you please advise on how to fix this problem? Thank you for your help.

I dump a STEVAL-SPIN3204 board in STMC Board Designer and want to add "Electronic Speed Control" Feature.In Board Designer I had add this feature without error. But in Motor Control WorkBench as attached 1.JPG .We can see ESC feature. But in project config stage, we can't find this feature as 2.JPG. Can anyone help on this question ?

We are using MCWB 6.3.2We generated a project that is working fine. However, testing our motor close to its peak current, we have been getting an over current fault.We decided to increase Over current protection (OCP) Digital Filter Duration and Threshold (well within our system limits). We then go to 'Project HW & Info' and Run CubeMx. From there we generate the project.Our main.c file is intact as well as the peripherals and pin configuration. However, we are not sure that the Digital Filter Duration  and threshold have been updated.Would you please, confirm that this is the correct workflow and where in the code I could confirm that our changes made through? We read somewhere that topology changes are not possible at this point, but this is not considered a topology change, correct? For us to generate new project every time would be very laborious giving that we have an extensive use of peripherals.Would it be possible to turn OC protection off and even DP off momentarily f

Hello ST Team and Community,I’m working with the X-NUCLEO-IHM07M1 board for 6-step sensorless BLDC control, and I need some clarification regarding the purpose and correct use of the GPIO_BEMF pin.In this ST Community answer, it is mentioned:"The GPIO_BEMF pin is provided to manage the BEMF sampling during the PWM ON state for 6-Step control only."I understand that this refers to enabling the BEMF voltage divider (e.g., 10k/2.2k) to bring phase voltage into the ADC range during PWM ON time. However, on the X-NUCLEO-IHM07M1, it seems that even during the PWM OFF time, if GPIO_BEMF is not pulled LOW, the voltage divider is disconnected (floating bottom resistor), and the BEMFx signal becomes unreliable or unusable for ADC reading.So my question is:Do we also need to pull GPIO_BEMF LOW when sampling BEMF during the PWM OFF-state (e.g., mid-off-time) in order to enable the voltage divider and get a proper ADC reading?If not, how is the ADC expected to receive a reliable voltage at BEMFx wi

Hello,      I use MCWB 6.4.0 & Motor Pilot 6.4.0, STLINK V3 MINIE.      Motor Pilot can not discover STEVAL-CTM010V1 board.      And  I find that MCU can receive datas at buadrate 1200 to 14400, but failed at 19200  or  more fast .      Does the STEVAL-CTM010V1 support 115200 baudrate ?  Or PC817B doesn't  support this baudrate?       this issue seems like this one, https://community.st.com/t5/stm32-mcus-motor-control/steval-ctm010v1-board-can-not-work/m-p/241708#M4301

I don't understand how to use this file can anyone please guide me with this. i know that i can directly control the motor controller with the pwm, and gpio pin. but i have this so i want to use this and make it simple.

Hello ST Community,I am currently using the EVSPIN32F0251S1 inverter board to control a BLDC motor in an elevator door control application.For this use case, I need to obtain precise motor rotation counts using Hall sensor feedback. While working on this, I found that the ST Motor Control Workbench does not provide a direct method or setting to access Hall sensor counts. To work around this, I manually modified the hall_speed_pos_fdbk.c and hall_speed_pos_fdbk.h files and was able to retrieve counts using HALL_M1.RevolutionCounter. However, whenever I regenerate the project through Motor Control Workbench, all these custom changes are lost. (i get reference from this post: bldc-motor-with-hall-sensor-keep-track-of-number-of-revolutions).Could you please advise on the recommended method to implement and retain Hall sensor count functionality, especially in a way that is compatible with project regeneration f

Hello,  I am using a STEVAL-ESC002V1 board and I am stuggling to make it work. I want to load the bin file given in STSW-ESC002V1 but the STM32Cube Programmer does not find the board. I am using a STlinkV3Minie connected to the SWD connector.The instructions given to use the board are really rudimentary and I am new to ST work environment so I am a bit lost. Is it a better option to use the bootloader? If so how do I do that?I'll gladly take any help.

Hi ST,I am trying to understand sensor less speed measurement using STO-PLL observer I did not get any idea for the parameters F1, F2, gain1 and gain2 parameters from user manual (STM32 motor control SDK user manual) and software code too. could you help me to understand how these parameters are computed by workbench by using motor parameters. this will help me lot. Thanks,Rahul D.

I am trying to plot reference speed and measured speed on graph in Motor Pilot. But in graph why measured speed is coming before reference speed? I tried it at different speeds but response coming is same.

Hi ST,I have generated dual FOC code using micro STM32F415zgtx and MC Workbench 6.4.0. I have to use STM32F767ZI in my application. Is It possible to port this software from STM32F415zgtx to STM32F767ZI and run two BLDC motors with FOC.Thanks,Rahul Deshpande

Hi everyone, I'm currently working on a project where I'm controlling a small DC motor using a PWM signal, based on the temperature read from an LM35DZ temperature sensor. I'm using an STM32 microcontroller, and generating the PWM signal with Timer2, Channel 2 (on pin PB3). The PWM signal is working correctIy, I tested it using an LED, which lights up fully at higher temperatures, confirming that the PWM output is active. The ADC readings and temperature conversion are working fine. I'm printing the raw ADC value, voltage, and calculated temperature via UART, and everything looks correct. The calculated PWM duty cycle is also being set properly using __HAL_TIM_SET_COMPARE(...). The problem is that the motor never spins. I'm using a 2N2222 NPN transistor as a switch, and a 1N4148 diode for flyback protection (cathode connected to +5 V, anode to the transistor’s collector). The motor is powered from a 5 V power bank, and I’ve made sure that the GND of the STM32 and the GND of the power b

Hello,Is there a way to power the control board of the EVLSERVO1 without using the power board? I would like to just play around with the MCU before connecting to 48V for motor control. The ST-LINK V3SET does not provide any power to the board. Br,Lukas
