STM32 MCUs Motor control

Hello everyone,I’m currently working on a motor control project using a custom board with STSPIN32G4 and STDRIVE101, which is similar to the EVSPIN32G4. I’m trying to control two motors, and I have implemented a single shunt resistor for current sensing.Issues faced:Spinning Direction: When the command is to spin in the positive direction, the motors end up spinning in the negative direction.Speed Control: The motor speed is not tracking the reference speed and remains constant.Some suggest using Motor Profiler to ensure the motor parameters are correct, but clearly, I’m unable to use Motor Profiler because it does not support a single shunt resistor configuration.For the speed tracking issue, maybe I can try using Motor Pilot? However, when attempting to use Motor Pilot and loading MC_FOC_SDK.qml, I encounter the error “ASPEP PACKET UNKNOWN”.Questions:Is there a way to use Motor Pilot to tune the PID parameters with my setup and how to solve the “ASPEP PACKET UNKNOWN” error?If Motor P

Hi all;I use the Steval-spn3202 control driver and x-cube-mcsdkh 5.6.0. I use the parameter of bldc motor is 12W, 12000rpm, 0.2A(Nominal current), 24V, 8ohm, 0.488H, 1.95 V/krpm.I want to control speed control or torque control with foc so that firstly, I selected speed control and senserless(observer-pll) on the st motor control workbench.I dont use neither encoder nor hal sensor. JP9, JP10 and JP11 closed on the Steval-spn3202. JP5, JP6 and JP7 open the Steval-spn3202. I made all configration for FOC (required short circuits and change resisitor).first case, I think that require measuring voltage level of the back emf on the pins (A0, A1, A2) of the microcontroller for position, But the software (st motor control bench) has never chosen these pins for sensorless and at the sametime, I checked from stm32cubemx software that has never chosen these pinsI dont understand how is bldc motor driven with feedbackless for sensorlessSecand Case, configuration of st mot

Hello guys I'm trying to do a profiler for Hall sensors.But when I measured my Hall power pins they only provide 3.3V instead of 5.0V and my Hall sensor needs at least 4.5V, I tried to check my control board manual and found that my SW is in the right direction but it only provides 3.3V, I tried to turn it off with CUBE MX (Save power of non-active UCPD - deactive Dead Battery pull-up). deactive Dead Battery pull-up) but it doesn't turn it off. Please provide me some suggestions. My control board with the power supply version isG474RE+IPM20B    

If, when generating a project, "attr not supported : Dmpu" Error message is reported, please ignore it for now. Issue is under investigation, and it does not prevent the project to be fully generated.

Hi, Good Morning            I want to control the motor through an analog input (PA4) (ADC2_IN17). However, I am unable to read the ADC value. The generated code lacks the initial configuration for ADC2 channel 17 in the MX_ADC2_Init() function.Please advise on how to call and read the value.I have attached the code, which works fine with the STM32H573 eval board.ThanksMathan

hello,  now i am trying to use MC workbench 6.3.0 to generate a simple design, but there are errors. the log is like below: what is worry with MC workbench?  please help.  thanks.

I am planning to drive the motor with FOC using the EVSPIN32G4 board.MC_WorkBench 6.3.0ST Motor Pilot V1.2.0 - profilerI checked the motor parameters with the ST Motor Pilot V1.2.0 - profiler program.And I created a project with the EVSPIN32G4 board and motor in the mc_workbench program.Speed Sensing Mode : Hall sensorCntrol mode : Speed ControlPotenionmeter : OnI uploaded the program after compiling it in the STM32CUBEIDE program.When you press the User1 button, power is supplied to the motor and the sound of electricity is produced.Even if you turn the variable volume, the motor does not run.When you turn it by hand, the motor starts to spin.I want the motor to start running as soon as I turn the variable volume.What should I do?   

Dear MCSDK,Thnak you for your nice work with this project. I am trying to use the McSDK with ST eval board B-g431-sec to control the speed of a small brushless PMSM motor with sensorless FOC.This motor with its load can rotate at approximately ~10k rpms (tested on another hardware using FOC with an encoder).With the eval board and MCSDK, things are quite Ok at low speed but I am unable to go higher than ~7000 rpms. At this speed my phases duty cycles are close to 100% and my PI speed (iqref) isn’t saturated.Configuration :Motors :R = 170mOHms (phase to phase)L = 20uH (phase to phase)pair poles = 7elec max frequency : 10000*7/60 -> 1160Hz !!kv = 0.67V(phase to phase) / krpm MCSDK (6.3.0) :PWM frequency : 64khzFOC frequency : 32khzsensorless : CORDIC with observer gains tunedfollowing Mcsdk documentationAny idea ?    

I need this webinar for understanding the bldc motor tunning.https://www.st.com/content/st_com/en/about/events/events.html/bldc-motor-tuning-using-stspin32f0.html 

When I try to start my motor by programming a torque ramp and starting the motor, if the motor fails to start, the motor state moves to FAULT_NOW with a startup error. The real issue is that I don’t know how to clear the fault. The state never changes to FAULT_OVER so I can never acknowledge the fault. I wish I could try to restart the motor without having to totally power cycle the system to clear the fault. How do I get a startup fault to transition from FAULT_NOW to FAULT_OVER?

Hello there,I am new to the MC Workbench and must configure the B-G431B-ESC1 to use it with a A2212/6T 2200KV Brushless DC Motor.I created a new project in the MC Workbench 6.3.0 and tried generating the project. Once the generation is completed I recieve the following error message: "Completed with errors."I watched the tutorial on youtube which shows different behavior. In the youtube video several ".c" files are being generated and the generation is completed successfully.What is my problem here?FYI: I created a custom motor profile, which is very similar to the "Bull Running BR2804-1700kv".Do you have any tips how to approach this, maybe use the Motor Pilot?Thanks in advance for any help.Best regardsBatu 

I used the Motor Profiler 5.4.8 program to extract the motor values ​​of the 12v custom motor in picture 1 and created a project in MC_Workbench to operate it. I bought an evspin32g4 board to test the operation of a larger voltage motor.How can I extract the motor value using EVSPIN32G4?There is no such board in the Motor Profiler 5.4.8 program.I can create a project in the MC_Workbench program, but I do not have the corresponding motor, so please tell me how to proceed.

Mạch B G431 ESC1, tôi vô tình xóa mã bên trong stm32f103 nên giờ tôi không thể kết nối với mạch, ai đó có thể giúp tôi với mã tệp hex để tôi có thể tải lại trên stm32f103 không. Cảm ơn

I found the motor value using the Motor Profiler 5.4.8 program (P-NUCLEO-IHM002).(Figure1)The Motor Pilot_6.3.0 program does not connect using UART.(Discover Board / Launch Profiler)(Figure3)Even if I change the UART Speed, the "Port Open and try to configure the board" error only appears.(Figure4)I bought EVSPIN32G4 to run the motor at 60v voltage level.However, I understand that motor measurement is currently not possible with the Motor Profiler 5.4.8 program.In that case, you need to measure it in the Motor Pilot_6.3.0 program.I can't check anything because the connection isn't working.MC_Workbench cannot create a project because there is no motor with similar specifications.Since I cannot receive the motor value from the motor manufacturer, I have to proceed through measurement. Please tell me how I can do this.

I am using P-NUCLEO-IHM03 motor kit which comprises a STM32G431RB series microcontroller, gimbal motor (GBM2804H-100T), X-NUCLEO-IHM16M1 I am interfacing LM35 temperature sensor to control the speed of the BLDC motor so as the temperature increases (eg. by using a soldering gun) the motor speed is also increasing so the motor is varying its speed according to the change in the ambient temperature but I am not able to print the value of the temperature on the console even though i have given the printing condition and in the live expression the value of the variable that is being displayed is not the right one too there is no proper ADC conversion happening nor I can read the temperature value.Please help me solving this issue

I'm currently working on a project using the STM32F303RE microcontroller, X-NUCLEO-IHM08M1 inverter board, and a PMSM NEMA 23 motor. I am attempting to run the motor using the Field-Oriented Control (FOC) algorithm but have encountered an issue where the motor does not run as expected.Hardware Setup:Microcontroller: STM32F303REInverter Board: X-NUCLEO-IHM08M1Motor: PMSM NEMA 23Problem Description:Despite following the setup procedures and configuring the FOC algorithm, the motor does not run. I suspect the issue might be related to timer configurations or other settings in my main file.

Hello,I am using the STSPIN32G4 IOC file from MC Workbench for a motor control example. However, I encounter the following errors during the build process. Since these files are auto-generated, I can't directly fix them by declaring the missing elementsError: C:/MCB Example/MtrCtrlMdlGen/temp/stm32g431rb_ihm16m1/Drivers/STM32G4xx_HAL_Driver/Inc/Legacy/stm32_hal_legacy.h:1007:47: error: 'OPAMP_POWERMODE_NORMALSPEED' undeclared (first use in this function); did you mean 'LL_OPAMP_POWERMODE_NORMALSPEED'? 1007 | #define OPAMP_POWERMODE_NORMAL OPAMP_POWERMODE_NORMALSPEED | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Hello,I have STSPIN32F0 Based Board for PMSM motor Drive. This Motor Works for Water Pump Application. we have Created 5 step in start up sequence using  MC workbench. Motor Rotate as per Profile upto start up sequence Complete. But as soon as Motor Switch to Close Loop it start to rotate on Full Speed Suddenly and that create problem in actual application for us(some time motor stall hear OR we receive Speed Feed Back error sometime). we need to set some acceleration time. after switching to close loop it will take some time to get high RPM. Also same thing we need when we send a STOP Command, Motor deaccelerate slowly and then Stop.We can't find any solution we are trying from many days, Please let me know that how can i implement above function of acceleration and deacceleration in MC workbench Generated Code.we are using sensor less FOC drive with single shunt measurement. I am using keil IDE for Coding.. Thanks
