STM32 MCUs Motor control

MCU : NUCLEO-F103 (STM32F103RB)POWER : NUCLEO-IHM07M1 3HI want to use a POTENTIOMETER to control the speed.How to? <MDK 6.2.1>MCU : NUCLEO-G431POWER : NUCLEO-IHM16M1 I used to a POTENTIOMETER to control the speed. 

I'm using ST workbench 6.2.0 and motor Pilot V1.2.4. NUCLEO+ IHM08M1, three shunt sensor and brushless motor with encoder. When the motor is blocked, using TORQUE control-->Torque Ramp in Motor Pilot, the actual drive current I_Q_MEAS is almost zero, although the Torque_Reference and I_Q_REF is shown to reach the expected value.Once the motor is unblocked, everything seems to be fine.It seems to me that since the actual Iq is almost zero, the drive isn't capable of delivering maximum starting torque.What am I missing here?

Hello everybody, i am new in ST. I am designing my own ESC.It is a control of a high power motor (950V, 400A Peak) to a BLDC / PMSM motor. I am designing my own power part and I need advice about the logic part, which NUCLEO is the best???Parameters: Vmax: 1200V, Amax: 400A, Speed: Max 20,000rpm.....There are quite a lot of them on MC WORKENCH, I guess the frequency is the better ???? Or is it something else? These are there to choose from, just tell me which is the best:- NUCLEO-C031C6 48 MHz- NUCLEO-F030R8 48 MHz- NUCLEO-F072RB 48 MHz- NUCLEO-F302R8 72 MHz- NUCLEO-F303RE 72 MHz- NUCLEO-F401RE 84 MHz- NUCLEO-F446RE 180 MHz- NUCLEO-F746ZG 216 MHz- NUCLEO-G071RB 64 MHz- NUCLEO-G431RB 170 MHz- NUCLEO-G474RE 170 MHz- NUCLEO-H503RB 250 MHz- NUCLEO-H563ZI 250 MHz- NUCLEO-H745ZI 480 MHzI assume that the best is the H745ZI (480MHz).Thanks: D

If I get the Ke from motor profiler,how do I calculate the torque constant (Kt)? How do I calculate how much current should I use for my output motor torque？  

HelloI understand the Nucleo 401 board was developed with the l6470 stepper motor driverI have been trying to interfacel6470 it with the nucleo 446re arm, with very little joy,... actually no joy due to the very poor C code support from ST and the L6470 / nucleo, the available code is very poorly written from ST, with 100s of lines of non meaning or important code, for just simply trying to set up a single board solution of the L6470 and sending some SPI instructions to the chip the ST C code / dspin code out there for the L6470 is so over the top complicated !! as it supports multiple nucleo boards and multiple l6470 stepper boards, and various configuration jumper settings, it is an absolute nightmare trying to hack and extract the code for a single board STM32F44RE solution with the L6470Is there any simply code to work the L6470 in basic building blocks that can port in to my nucleo 446RE / SPI bus? or better any video tutorial on how to configure the L6470 icthis is a simple SPI i

Hi AllI hope someone of ST Micro's engineer show this.I'm working on for sensorless BLDC motor control using six step method. I use STM32G474 Nucleo board for test.To realize the six step control, I use TIM1 and TIM2 synchronization for commutation. The modulation I use is high side sync rectification PWM modulation. Approximately, six step control works. However, there are some problems that timing at the time of commutation is not match as below figure.. I will upload the waveform of the PWM signal recorded by Saleae Logic. In my application, not use Hall sensor. The target output is that the PWM switches correctly during commutation as shown in the figure below. In the figure is writen that "write CCxE, CCxNE, and OCxM for next step" after a COM event for the next step.I wrote the code according to this, but it cannot be improved by any combination of settings.So, I want to ask to ST Micro engineer, if possible please show me a simple sample code.My code for set

I m using STM32L552ZE as SPI Master and slave device is L6470 stepper driver. Write operation everything is fine. While i tried to read the data from STATUS Register (0x19) or GETSTATUS register(0xD0). I received only floating values not a constant one. So i had doubt about read sequence.This is my code.uint32_t SPI_GetStatus(uint8_t command){static uint8_t TramsmitData[4];TramsmitData[0] = command;TramsmitData[1] = 0x00;TramsmitData[2] = 0x00;TramsmitData[3] = 0x00;static uint8_t receivedData[4] = {0};for (int index = 0; index < 3; index++){HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_RESET);HAL_SPI_Transmit(&hspi1,&TramsmitData[index], sizeof(TramsmitData[index]), HAL_MAX_DELAY);HAL_SPI_Receive(&hspi1, &receivedData[index],sizeof(receivedData[index]), HAL_MAX_DELAY);HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET);}DebugLog("receivedData[0] %d \r\n",receivedData[0]);DebugLog("receivedData[1] %d \r\n",receivedData[1]);DebugLog("receivedData[2] %d \r\n",receivedDa

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

Please review your selections. How to change json file?

Hi team.I want to drive BLDC motor in 6-step method like below figure.Is there any sample code for this method? Slide Link 

Hello,I am having difficulty getting my motor to start reliably and smoothly.  Sometimes it starts as expected, but sometimes, it just wiggles around it's start position.  If I spin it by hand in the direction it's supposed to go, it starts spinning on its own as expected.  Also, if it's already spinning in the correct direction when I enter speed control mode, it also spins on its own as expected.I have attempted following the steps in HSO_Startup_Guide, but can't seem to get the results listed.My setup:Motor Control Board: B-G473E-ZEST1SPower Board: LVLP01Motor: MOONS R57BLB50L2 (recommended for zest eval kit)Results of motor profiler:RsDC: 0.359 OhmRsAC: 0.371 OhmLs: 0.000690 HenryFlux: 0.0130 WbIsc_A: 18.8Akt_Nm_A: 0.0389 Nm/APol Pulse ParametersPulse duration: 8 periodspulse current goal: 4.4Adecay time 11 periodsResult PulseDuty: 0.97To get oscilliscope traces:Current: I soldered leads onto TP9, TP11, TP13 (power board op-amp outputs).  I read one of these at

Trying to evaluate a Maxon 323217 Motor with the STEVAL-SPIN3201 and not having any luck.  Using MCSDK6.2 with Motor Control Workbench 6.2.1 and Motor Pilot 1.2.5.  The motor is configured for position control using a 512 count ABI encoder.  I've tried sensorless w/ Torque and Speed Control / Hall w/ Speed Control / Encoder Position Control / Encoder without Index Speed Control.  None of the configuration's work at all.  The system is unstable in almost all configurations.  Tried PWM Frequencies 10kHz / 16kHz / 20kHz with the later two with the current loop running at half the PWM rate.  Tried using the automatic calculations using Auto Calculate Torque/Flux Kp & Ki and tried custom values based on another system which correctly works for this motor.  Set electrical alignment to index pulse = 0 as per the Maxon datasheets.  Also tried measuring the BEMF on A-B and setting the offset angle to the index pulse that way (

 Hi,We've been evaluating our BLDC motor with the X-NUCLEO-IHM11M1 board, and I wanted to share some observations and seek clarification on certain aspects.We noticed that the motor rotates smoothly only when the six PWM inputs are connected to the oscilloscope. When the PWM inputs are not connected to oscilloscope, the motor encounters difficulties in running. To address this, we implemented pull-up and pull-down resistors to the PWM inputs, and the motor now works smoothly.Could you please provide insights into why this behavior occurs?Additionally, Please provide an explanation on the effects of adding pull-up and pull-down resistors. We observed that the motor rotates in one direction when pulled up and in the opposite direction when pulled down. 

I am able to do a 12v motor profile with the old mcsdk 5.4.8 successfully with running motor current at around 0.2A no load, settings are 4 poles pairs, 1A max, 4000rpm max, 12v, sm-pmsmPower supply at 12v, current limit 6AProblem:Using mcsdk 6.2.1 with b-g431-esc board with the same 12v motor and settings, it error up over current.I use the default example and just tick the motor profiler at the application config section and untick the electronic speed control at stage config, no other settings touched and then generate it for iar/cubeide with firmware package version 1.5.1Build and flash without errorwhen run motor pilot 1.2.5 profiler it showswith a 1ohm and start profileold mcsdk 5.4.8 FOUND the solution to it, in case anyone experience over current every time like me, just increase the filter duration   

Hi, I have following Harware configuration: - X-NUCLEO-IHM16M1 (STSPIN830)-  NUCLEO-L476RG BLDC Motor with three analog hall sensors I'd like to be able to configure your Motor workbench to do the job. Questions:-   Are the boards X-NUCLEO-IHM16M1 + NUCLEO-L476RG compatible ? I suppose yes-   How  would you configure position control for analog Hall sensor with your motorworkbench ? Do you have any api or docs which might help ?Many thanksYounes

While going through the MCWB SDK documentation for MCSDK6 (MC_SDK_6.2.1), I found that there are documents linked that refer to either outdated or unavailable sources.I will put them into this post as I find them.  "STM32 motor control SDK overview" section 2 "Motor control application workflow" refers to document AN5166 "for more details on the interactions between STM32CubeMx and STM32 motor control workbench".This document seems to be for an older version of the MCSDK and is not available. A link to it found in the ST wiki is 404.

I am currently facing an issue with my motor control setup, and I was hoping to seek your expertise in resolving it.I am using the STEVAL-IPM10B and NUCLEO-F302R8 with Motor Control Workbench, and I am encountering a challenge in achieving low RPM. Specifically, I can run the motor at 500 RPM and above successfully, but I am unable to decrease the RPM below this threshold.I would greatly appreciate it if you could provide guidance or assistance in troubleshooting and resolving this issue. Any insights, recommendations, or steps to adjust the settings in Motor Control Workbench for achieving lower RPM would be extremely helpful.

Currently I am using FOC control on a PMSM.How do I apply a holding torque to a motor so that I can lock the rotor.   Thanks

Hi,I am working on a project with an STSPIN32G4 motor controller and using MCSDK 6.2.1. The motor I am working with has a quadrature encoder with 1024 cycles per rotation. It's not clear to me in MC Workbench whether I should enter in this value, or multiply by 2 or 4, to get "pulses per mechanical revolution."Thanks,Aaron

I set up a BLDC position control with NUCLEO-F446ZE and X-NUCLEO-IHM07M1. The BLDC motor has integrated rotary encoder, which is connected to X-NUCLEO-IHM07M1. To verify the accuracy of the integrated encoder, I set up an extra optical encoder, which is connected to NUCLEO-F446Ze Timer 4. Timer 4 is configured as encoder mode, see below, with GPIO PD12 (A), PD13(B) and PD14(Z).Weird thing is that if I start the motor by command "MC_StartMotor1()", even if the motor is not moving, the reading value of TIM4->CNT keeps changing (cycles from 0 to 65535). If I stop the motor, the reading value of TIM4->CNT remains unchanged. Under this condition (motor state Idle), if I manually change the position, the reading value of TIM4->CNT changes accordingly and seems normal. Anyone knows what happens there?
