STM32 MCUs Motor control

Dear all,I have a NUCLEO-F302R8 and the X-NUCLEO-IHM07M1 motor driver expansion board. I have a three phase BLDC motor with an encoder attached to it. I have profiled the motor and I am able to run the motor in the profiler. When I use the workbench software to implement a speed controller or a torque controller the motor does not spin. Attaching the encoder to an oscilloscope has shown a correct signal. When I use the torque controller, it seems that the motor is trying to keep a constant position. Nothing happens when a speed controller is active. Do you have any ideas on how solve the problem and get the motor to work?

The V5 motor control workbench had an "UPDATE" button to update the ioc without losing user added changes. The current V6.1.0 workbench doesn't have the update button and always generates a new ioc file, losing all of my additions that took an hour to add. How can I update the ioc file in the workbench while still keeping the changes I added in cubeMX?From another post - "Project is initially generated by the MC workbench.IOC is loaded with cubeMXUser add other peripherals, (SPI, additional GPIOs etc...) and save the customized IOCUser wants to update the Motor control parameters inside his customized IOC.If he applies generate, he will loose his IOC.the Update button will modify only the MotorControl IP inside the IOC."This no longer works in workbench V6.1.0Any ideas?Thanks

Dear support,I am designing a ACIM driver. I want to change MCU to 48 pin LQFP package. but example is only has 64pin MCUHow can I change to MCU type?thanks for your helps

x-cube-mcsdk's position sensorless FOC(STO+PLL) startup and position accuracy tuning are very difficult.If you have any tuning methods or Matlab/Simulink models, please share them.

Hello,For our battery-powered smoke extraction fans, we want to develop a brushless motor driver 1.5KW.For this new development we use the reference STSPIN32G4.I use a custom EVSPIN32G4 circuit board with a 4 pole pairs brushless motor equipped with hall sensors.I use MC workbench 6.2.1 for the application.We have a product who work fine with the software configuration in hall sensors.Today we want to migrate this application (fan application) in sensorless mode. in sensorless mode, I am encountering some difficulties:About 1 in 20 starts goes wrong and ends up with a speed fedback error, the other 19 starts happen normally. I would like to have advice on finding the right setting knowing that I have already followed your recommendations in your various supports. I have tested : different value for the regulator settings, different value for Pll ki and G2 value. Here is a description of the malfunction: Each time the speed feedback error appears, the propeller of my fan is st

Hello ST, we are working with B-G431-esc development tool to control motor. When we worked with your board the motor performance is to good and sensing voltage and sensing curront is good.  We designed same esc with our specification we are not getting sensing voltages and sensing current and some time PWM generation is not going and we are facing lot of problems in our board and we have some other issues in that esc can you please help me the B-G431-esc project.

hello everybody:    l'm currently debugging the FOC motor with MC Workbench.the development board model used is NUCLEO-G431RB and X-NUCLEO-IHM16M1.Now l have achieved closed-loop control of the motor through the encoder.Now l need to test the open-loop control motor,l have the following questions to consult:1、l opened the open loop control,but after comparing the project found that there is no open loop control part of the code,l want to ask whether the open loop function is supported.If so,how do l configure it.2、When l set the main sensor to observer+PLL and the auxiliary sensor to none,can l use it as an open loop by setting the sensorless start-up parameters?My target speed is 600rpm.3、Can the main sensor be set to observer+PLL and the auxiliary sensor be set to encoder to do open-loop control before the encoder closes the loop.

i want to create a firmware for the stspin32g4 mcu but the cubeMx let me not select this mcu. in fact no spin mcu. i can not select a mcu with name spincubemx bug or st now not support the mcu with integrated drivers?

Good day all. I want to learn about mc worckbech. I want to coustem with mcu STM32f401 and a part of st driver are suport HIN and LIN for drive the mosfet. I want to use quadature encoder 2000ppr. It is posible create by mc worckbench?? And i want to control the motor by step/dir it posible to add also in the frimeware?? Isee somebody are maked but with B-G431B-ESC1So this is very"expensive on my country. Easy to find for stm32f401. And some mosfet from st and driver also. Or posible to use IGBT+driver??.  

Hi.I m new at ST MCSDK and i was reading some documents about mcsdk position control until waiting for my custom board arrive. I have few questions about encoder mounting and alignment operation.According to the documant AN5464; it seems that for fine positining bldc needs encoder alignment procedure before starting application. If Z index preset, motor will turn 360degree until it find out Z index signal. Without Z signal what will happen on the algorithm ? Without Z signal , can it be turn smooth at ultra low speeds or first commutation with fine positining  ?  Can you explain with more details ?In my country its really hard to find low voltage ac servo motor which factory default encoder attached. For this reason i thought that maybe i can attach an encoder to the custom drone motor.There are lot of drone motor types available in my country at very low cost but unfortunaly as you know they have neither encoder nor hall sensor includes. If i buy one of those motors and atta

I am using the B-G431B-ESC1 inverter board to drive my brushless motor (10 pole pairs) using the FOC algorithm. The brushless motor comes equipped with hall sensors used for commutation and an MT6701 quadrature encoder with a 1024 PPR resolution.NOTE: I do not intend to use the hall sensors in this application. Only the encoder. However, if you believe there is a way to use them for commutation in torque control mode, I'd like to kknow more about how to set that up. I am using an ESP32 where my PID controller is coded. My ESP32 receives speed setpoint input from the end-user and speed feedback from the MT6701 encoder on the BLDC motor. The output of my PID controller on the ESP32 will be the PWM signal that is sent to the PWM input of the B-G431B-ESC1 board.I have set the control loop of the inverter board to be the torque loop, since my speed loop (outer loop) is sitting on my ESP32.With all that said, I have a question on how to configure the parameters of this board for such a

In the latest version of the STM32 Motor Control Workbench (6.2.1), I am unable to select hall sensor-based speed control for my STM32 Nucleo F030R8 board with the IHM08M1 driver. Despite selecting hall sensor in the motor specifications, the option does not appear in the configuration. How can I enable hall sensor-based speed control in this setup? the same is possible with older motor control workbench versions like 5.y.4/5.4.8...etc

I can't generate Sixstep with a custom board, it starts spinning immediately with FOC but stops when the motor reach one tour

I am facing issues while running a BLDC motor using the 6-step algorithm on the STEVAL-SPIN3201 board. The only modification I have made is to the Hall effect sensor low-pass filter to address noisy input signals.I am encountering the following problems:Current spike on startup: When starting the motor I apply a soft speed ramp, still I get this current spike on the phase current, which sometimes result in 'Over Current' Fault. What can be done to mitigate this? Speed fluctuations: The motor speed fluctuates around the reference speed, resulting in uneven current draw (see "1500rpm_no_load.png"). I have tried adjusting the speed regulator tuning to be less aggressive, but this has not resolved the issue.Current Spikes: Occasional current spikes in the phase currents trigger "Over Current" faults.Do you have any suggestions on how to address these problems?The .stwb6 project is included in the Info.zip file

I am designing a BLDC motor controller using STM32F103C8T6. I am using "XOR ON / Hall Sensor Mode" for reading the motor's hall sensor. But if the motor is rotated quickly, the hall sensor value does not update. The hall sensor value updates properly if motor is rotated very slowly. I have removed all other parts from the code, The only code in the program is of reading hall sensor pins.  void TIM4_IRQHandler(void) { /* USER CODE BEGIN TIM4_IRQn 0 */ hallPosx = ((HAL_GPIO_ReadPin( HW_GPIO_Port, HW_Pin ) << 2) |(HAL_GPIO_ReadPin( HV_GPIO_Port, HV_Pin ) << 1) | HAL_GPIO_ReadPin( HU_GPIO_Port, HU_Pin ) ); ); if (0U == LL_TIM_IsActiveFlag_UPDATE(TIM4)) { /* Nothing to do */ } else { LL_TIM_ClearFlag_UPDATE(TIM4); } if (LL_TIM_IsActiveFlag_CC1 (TIM4) != 0U) { LL_TIM_ClearFlag_CC1(TIM4); } else { /* Nothing to do */ } /* USER CODE END TIM4_IRQn 0 */ /* USER CODE BEGIN TIM4_IRQn 1 */ /* USER CODE END TIM4_IRQn 1 */ }  This

Hi GuysI have a question about space vector modulation implementation. I'm reading a code for ST MC workbench designed to run SVPWM. there is calculations for sector identification in space vector that I can't get it's idea completely. if someone analyzed these vector calculations please help.thanks alot.

Hi there, I recently purchased the B-G431B-ESC1 and when I connect it to my USB port, immediately a red flashing light appears. There are two other solid green lights. I am also not able to connect my ST-LINK to flash firmware, and this may be related. But for that I am having issues installing the necessary drivers on my Windows10 laptop. I have downloaded the relevant drivers and upon installation I am told that they were installed successfully, yet when I launch Device Manager I am not able to see them anywhere. Furthermore, when I try to launch the ST-link utility software I am told it is unable to launch because of some missing DLL files, namely mfc140.dll, VCRUNTIME140.dll, and MSVCP140.dll. With a little online research on forums I see many suggesting I reinstall Visual C++ Redistributable. So I do that just (I remove what I had and installed Visual C++ Redistributable). But it did not help at all. Any help to get me started with this board would be

I am trying to tune a 28 pole 50V 20 Amp  motor 6 step  with hall sensors. Motor Pilot does not work for me. To get over this I am using STM32CubeMonitor to plot the speed response. I have also tried to change the values through Cube Monitor by writing to PID_SpeedHandle_M1.hdDefkpgain and even though the values change it has no effect on the performance. Changing values (#define PID_SPEED_KP_DEFAULT) in the drive_parameters.h file and recompiling does not work either. I am only able to change the Kp values by going back to workbench and  completely regenerating the project, which is a time-consuming operation. I would appreciate some advice - thanks.

I'm finalizing the design of a BLDC motor controller (up to 48V / 40A) and I'd like it to work well with HSO and (when available) ZeST.From other forum posts I've found the need for phase voltage measuring and to be able to capture these simultaneously. The board already on the face of it the current board config looks compatible:STM32G473 MCUIn-phase shunts (and an external 50x bi-directional OPAMP)ADC (rank) assignment:ADC1: VM / bus voltage; 2 extra (low speed) voltage inputs and several NTCsADC2: Phase A voltage & CurrentADC3: Phase B voltage & CurrentADC4: Phase C voltage & CurrentFiltering (low-pass cut-off frequencies):VM/bus voltage: 1.5kHz (fixed)Phase current & phase voltage: 12 or 150 kHz (all voltage filters switch together, all current filters switch together)Questions:Is the above ADC configuration compatible with ZeST and HSO? If not, what should be changed?What is the optimal low-pass cut-off frequency for the phase currents for HSO and ZeST?Likewise for

Hi please a can not build the sample application of STEVAL-PTOOL2V1.Have any newer version of application? I download this https://www.st.com/en/embedded-software/stsw-ptool2v1.html but not compile?what should I do ? I have to install something in cubeMX or CubeIDE?Why this board not have suppont on MC WorkBench? 

We need to implement a number of additional ADC channels in our custom board, on top of what the motor control application requires.The MCU in question is the G431, the overall inverter design is based on the B-G431B-ESC1 with FOC and three-phase sensing enabled.The MCU provides 2 ADCs, both of which are used by the motor control application.For implementing the additional ADC channels, I added them as single-ended ports via the CubeMX to the motor control project.Now I'm wondering, what are the limitations that I face? Which options in the ADC configurations can or can't I modify (speed, analog watchdog, oversampling)?Can I use DMA?How many custom application ADC channels am I allowed to add? I need at least 5.Could I also use the additional ADC1 options like temperature sensor channel and Vbat channel?How do I work with these custom application ADCs? According to some topics I found for older SDK versions, I need to use the "Regular Conversion Manager" for this.
