STM32 MCUs Motor control

Hello Can you point me to some documentation regarding the tuning of the PI control loops in motor control workbench, I found this video https://www.youtube.com/watch?v=Tmq2PL8bf3g&list=WL&index=40, this outlines the procedure using the rev-up table current clamp and oscilloscope in sensorless FOC, however this method does not appear to work when using sensored mode(hall sensors) as the rev-up table in motor pilot appears to do nothing. I am using ST MCSDK 5.Y.3 Full version and STEVAL-SPIN3201RegardsIan

Also there is one pin that is connected to potentiometer.but there is no any options in st workbench to varry the speed using potentiometer. I look forward to hearing from you as soon as possible.thank you

hello everyone,ı am trying BLDC motor driver with stm32f302R8 but ı having a problem with comp4 and comp6 interrupt. when ı input COMP4_6_IRQHandler, ı try to distinguish comp4 and comp6 interrupt. but both comp4 with comp6 be activating. ı can't find solutions. please help me.

Hi, I am using board B-G431B-ESC1 and Motor Control 5.Y.3.When controlling the motor through the Motor Pilot and increasing the current, I get a recurring Bad CRC Header error.There is a neighboring forum thread where this is discussedhttps://community.st.com/s/question/0D53W00001FlPJ2/why-am-i-getting-the-faultover-fault-when-using-the-st-motor-pilot-And there was a proposal to reduce the speed of USART, but this did not lead to anything for me, I tried it at speeds of 115200 and 1843200.If the motor is standing or moving without load, everything is fine, but as soon as the current increases and reaches, for example, 5000 units of s16A, then this error begins to appear.

Hello. I have a simple project, but I have a hard time doing my project in STM. The difficulty of the project is that all processes have to work at certain sampling times. As you can see in the picture, I have a robot that is controlled by 2 channel biological signal (EOG). Robot movements are measured with two potentiometers. So what do I want? 1- I want to transfer 2 channels of EOG data controlling the robot and 2 pot data that allows us to measure the movement of the robot to the SD card or PC via serial port (1KHZ sampling, the transfer does not have to be real time).2- According to the EOG data read, there is a linear function that provides the movement of the robot's joint (m*x+n). The PWM value (min. 10 KHz PWM) produced with this function will be transferred to the robot actuator via the driver.In the first attempt, while recording the data to the SD card with DMA at 1KHz sampling time, I could not generate PWM signals from that data. Therefore, I performed the recording

Hello,The first torque ramp command that I start always has a strong overshoot/an unwanted motion. The same command applied right after, with or without having stopped and restarted the motor, behaves as expected.All the next speed ramps are executed without this overshoot. I expect the motor to not moves when I set and start a torque ramp to 0 s16A in 0.05s and that the motor is already not moving, and without resistive torque applied.What could be the cause of this phenomenon ?Setup: I use a Nucleo G474RE with MCSDK 6.0.0. I send commands to the Nucleo using ASPEP and MCP protocol over UART. I control a BLDC motor in FOC mode, 3 shunt configurationI have a 1204 pulse quadrature encoder used as main sensor

Hello,I would like to drive a simple DC motor with a STM32F446RE.I use the VNH5019 as motor driver.Everything works so far. My only question now would be, is there a ready-to-use library or perhaps a way to embed the component into the software via STM32CubeMX?Thank you very much

HiI am running on a STM32G071 board, with my own custom HW (standard 3 phase halfbridge). The control is FOC sensorless with 1 shuntI am having problems tuning the motor, but for starters I would like to run the motor at low speed in open loopI can find a parameter in the IOC file name Open_Loop_FOC which I can set to "true"But how do I set the operating conditions and how do I start the motor in Open loop mode?(I am running MCWB 5.4.1.19309 (I have tried 5.4.4, but it seems to be unstable. STM32CubeIDE 1.4.2 and STM32CubeMX 6.0.1)RegardsKlaus

I have an issue where I keep getting a startup fault. But the motor gets up to the speed its commanded to. I don't have this issue with the demo (IMH07M1) board, but I do with my custom power stage. The only way this would fail is if the pointer to the next phase is null, but it should exit this before it gets to the end of the phase Linked list... I'm starting my observer at stange 2, theres 5 phases... I'm very confused also why this would fail using one hardware and not another when both spin the motor and get up to speed. Thanks!

I have a NUCLEO-F302R8 that I am trying to configure via the Workbench, but there are only 5 control boards shown in the new project setup screen:NUCLEO-G071RBNUCLEO-G431RBNUCLEO-G474RESTM32G081B-EVALSTM32G474E-EVALThats not a lot of options, so what am I missing to get support for all the other micros?

I have several .stmcx files to generate projects for. I don't have the time to open, generate, and wait for each one to generate. Is there a way to automate this process, preferably through Windows command line or Linux Terminal, though writing a C, C++, Python, Java, etc. is also workable.All I need to do is generate. I do not need to change any parameters or configure anything, just click the generate button and wait the ~2 minutes for it to generate.Thanks.

I am trying to find / create a program to run an IPM module that will run an a/c compressor(PMSM). Like a MC3PHAC 6 pwm generator.Never written a program before except change some values to make the led blink faster.Have a NUCLEO-F401REIPM module: PS21245-ENeed help writing/finding program

I am using the motor control code in the cube IDE generated by the motor workbench . How can I send back the speed of the motor to the console? Can I use HAL_Uart? Right now I am not getting any response

Using IHM001 kit with F302R8 and IHM07M1 boards and bullseye motor. Have found motor info using the motor profiler. From the MC workbench, generated code and then in the main.c file done simple start stop sequence (as shown in the step by step guide wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_Motor_Control). Motor starts/stops around 3 times, then MC workbench shows speed feedback fault error and won't restart. I have looked in the motor control FAQ and tried some changes suggested but no luck. As this is part of a motor kit, I was wondering if there are any specific extra settings I need to change, eg. in start up ramp?

I would like to control a low voltage three phase BLDC motor using field oriented control with an STM32 microcontroller and appropriate motor drive hardware.is there a solution available from ST to start to this development like a motor drive expansion board with an available SDK for field oriented control that supports the STM32F746. RegardsIan

I found the following document: STM32F PMSM single/dual FOC SDK v4.3.This has a section (14) which has some explanation to how serial comms with a motor control device can work. There is even a list provided of "relevant motor control registers", however, I do not see or can I find the actual description for the content (bits/bytes) of these registers.Secondly, to save me some development time, I was wondering if there are already libraries that would be helpful for use with a master device to command and query an STM motor control device? If so, where can I find these and are there any necessary modifications that need to be made to any of the files, so that I can make use of them in my project (stm32cubeIDE)? Note: My current setup is a B-G431B-ESC1 (motor controller) with a stm32f405 (master device).Your help is much appreciated.

We are using the B-G431B-ESC1 board. To generate the project, we use the X-CUBE-MCSDK-6 SDK. The description of the board says that the board can work with BLDC motors. But the SDK description says that the SDK is for PMSM only. Can you tell me if the software generated with the SDK will work with BLDC motors?

Hello, Did anyone attempt to use the motor profiler toolkit with these boards : STM32 IHM07M1 & STM32F401RE? I configured mine following the "motor control mode" from ST website and the program starts but then nothing happens and the following error message appears : "The measurement is taking too time".On the other hand if I use the motor pilot tool with some approximate motor parameters, everything woks fine, so I think the problem comes from the indications on how to configure the board in the beginning for the profiler.Any help would be largely appreciated! Thanks a lot in advanceFlorian

I saw multiple resources on different conversions between chips, such as AN5094 (between F3 and G4), but I can't find anything for G4 to F7.Is there a step by step process to follow that has a program do most of the work, something similar to MCSDK, but with an already generated project?

When Motor profiler is used to test the motor for its parameters, it keeps on checking with the possible current (18A, 14A, 9A, 6A, etc..). After sometime a message popup "Speed measurement takes too long time". I don't know the reason behind this. If same motor is used with 24V power supply, motor profiler works and able to run the motor using motor control workbench.

Hello, do you have any application on the use of variables:execution rateCut-off frequency
