STM32 MCUs Motor control

I am getting the fault of MC_DURATION after running for few seconds in my customized board but software is same as B-G431B-ESC1. I am not sure why this error is happening, any advise? I have changed the REGULATION_EXECUTION_RATE to 2 from 1 assuming the FOC execution rate is fast so that the FOC is executed after 2 PWM cycles.

Hi all,I am working on BLDC motor control using Hall sensors. At the moment, the motor seems to be running fine, however, I have noticed something strange in one of the sequences (this can be seen in the attached image taken from an oscilloscope). When switching from PWM stage to floating, I do not see these spikes and waveforms that can be seen in the switching from GND to floating. Thus, I am a bit concerned as this floating stage is used for sensorless rotor position estimation through BEMF zero crossing. Could it be that one of the switching sequences is not working as expected? Looking at other BLDC phase signals from internet, it seems that those oscillations during the floating stage occur in both cases. Does anybody know how to infer the correct sequence for a BLDC motor? (I am using BLDC RS Pro 24V and it does not contain any information on how to program the sequence. Looking at ST and other manuals about BLDC do not match the sequence I am applying to rotate it.)Thank you in

I can easily create 3 PWM signals with 120 degrees of phase shift by creating a Master/Slave Trigger configuration. However, for the FOC algorithm, I need to shift all the signals together during operation. How can I achieve this?Both STM32CubeIDE and Simulink Embedded Coder answers are welcome.

I am using the software of b-g431b-esc1 and the driver used in the board as per schematics is in my board the micro is RB series but the problem is with the Mosfet driver which has an active low signal, IR2108What changes do i need to make in the software to make it work? Will it be huge or minor changes? Please advise.

I'm trying to use the Motor Profiler software through my Motor Controller SDSK 6.1.1. When I launch the profiler, I Select my boards - Nucleo-F302R8 and X-Nucleo-IHM07M1 3Sh. Then I set the motor parameters to match my motor Bull Running BR2804. When I then hit Connect I get a warning to update the board firmware. I select Accept and then the process gets stuck forever on the "Checking ST-Link connection" step. What might be the issue here?

Devkit: (B-G431B-ESC1)Motor: (Pole pair = 3, (6 total magnets))Hall Sensor: Honeywell SS41F, 40 mechanical degree placement and 120 electrical (odd mechanical placement due to 3 pole pair)Software: MC SDK V6.I am trying to use 6-step sensored control. I have a 3-pole pair (6 permanent magnets) motor. The hall sensors are placed 40 degrees apart mechanically so that I get 120-degree electrical spacing. The V5 and V6 MC SDK only support 120 and 60 mechanical degrees for hall sensor placement. I am wondering if this is contributing to my problem below. The problem is that when I try to spin the motor up, I get speed feedback error in the MC SDK motor pilot tool.I am able to spin the motor using L6235 no problem, instilling confidence in my motor and hall sensors.I have tried all 6 combinations of phase wiring.MC SDK 6 config attachedAny thoughts or ideas welcome.Thanks,-Sam HansenThank you,

Hi all,I am new to motor control, and I am currently working with the BLDC motor driver board STEVAL-SPIN3201 (based on the STSPIN32F0). I am trying to generate the corresponding PWM signals to drive a BLDC motor. Although the low side of the bridge is working, whenever I try to drive the high-side MOSFETs I get a voltage of around 40 mV in the midpoint between the high and low side of the bridge (e.g., OUTU). When looking at the signal through a oscilloscope I get the attached outcome. Does anybody know what the issue could be? Am I missing something in the control logic driver to enable the OPAMPS?Also, when I disable both output compare signals (OC1E, OC1NE), I get a voltage in OUTU of around 11 V (supply is 24 Vdc). Is this correct?Hope that everything is clear. 

According to AN4144, page 14/28, the coefficient 'ke' is measured by turning the stepper and measure the phase voltage with a oscilloscope. For the coefficient 'ke' in V/Hz, which voltage normation should be used:Peak-to Peak, Peak or RMS?.

I'm building a project around the B-G431B-ESC1 board, that claims to support hall sensored 6-step control, but in motor bench there are no example files for this (only sensorless electric speed control files). I know you are supposed to generate files in motor bench and then set six step control method in CubeMX. But when I do that, I get bunch of errors in CubeIDE that I'm missing many necessary library files. When I link them in project options for compiler files from different project (that is FOC and does have them), I get the same errors. When I go back to Motor Control and update the same project (which theoretically should add those needed libraries) it rewrites the code and sets the control method to FOC (like it would ignore anything you'd set inside CubeMX). So my question is how to set up six step control?I've spent enormous amount of time trying to resolve this, but to no avail.

I want to add my own board, but there is no documentation how to add.

I have a driver board with 2 inline current sensors (ICS).But I cannot find a way to configure the current sensing with ICS option in MCSDK 6.1.1.Please support on how to configure this or provide a JSON file for the driver board with ICS option.Many thanks!

Hi, I'm setting up a custom board with STM32G431CBT6 to control a 6-step bldc motor. I want to use comparators to protect against overcurrent.My problem I configured the bkin input and comparators. the bkin input works, the comparator also works separately (puts out an external signal). But the PWM does not stop when the comparator is working. I can see the active output of the comparator, but it has no effect on the pwm.I created a simple program to test this, no motor control, just complementary PWM.I want it to work at the hardware level. Can someone tell me what I'm doing wrong?I add screenshots and code.MX_GPIO_Init(); MX_TIM1_Init(); MX_COMP1_Init(); MX_DAC1_Init(); /* USER CODE BEGIN 2 */   HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1); HAL_TIMEx_PWMN_Start( &htim1, TIM_CHANNEL_1 );   HAL_COMP_Start(&hcomp1);   HAL_DAC_SetValue(&hdac1, DAC_CHANNEL_2, DAC_ALIGN_12B_R, 4000); HAL_DAC_Start(&hdac1, DAC1_CHANNEL_2);   HAL_DAC_SetValue(&am

The firmware file doesn't seem to exist here (https://www.st.com/en/evaluation-tools/b-g431b-esc1.html).Are there any hex or bin binary firmware files built for b-g431b-esc1?If the firmware file exists, it would be appreciated if you could tell me where it is.

Hello I am using a custom design with the STSPIN32G4. Running open loop space vektor commutation works, but after a random amount of time the motor simply stops.Surprising is that if SPI is active the error seems to occure sooner than normal. Everything else seems to work fine (Control loop interrupt, main loop, i2c communication, SPI communication even the timer1 interrupt).No protection fault is being generated by the Driver. A reset and clear of the driver does not help.A software MCU reset seems to solve the Problem for a moment.Without a load it seems the problem does not ocure. So my thought is that it is an EMC problem. But why does it only effect the driver or the timer?Is there a recommended layout or a layout guide for the STSPIN32G4?I think since a MCU software reset solves the problem temporaly and I would assume that the reset does not affect the Driver. The problem is within the Timer1.Does anyone know how I could investigate it further? Should I reduce the FET driver cur

I have a X-NUCLEO-IHM16M1/NUCLEO-G431RB eval board I am trying to connect to a motor with hall sensors. The motor has leads labeled Hu, Hv, and Hw, but J1 on the driver board is labeled A+/H1, B+/H2, Z+/H3. What is the correlation between these two nomenclatures?Thanks,Dan

Large number of mistakes observed in the MCSDK documentation UM1052. This is the park transform and the same thing is repeating. Is he trying to say Ia, Ib or Ialpha or IBeta. I think very little effort in creating the document. There is a mention of Theta but not captured in the figures. Very confused to refer or not this document.

We are working on a board with, among other things, TPS56637 and TPS62913RPUR voltage regulators, a couple of DRV8912-Q1 motor drivers, two ALM2402-Q1 op amps, and an analog subsystem measured by an STM32G474 MCU. What type of separation of ground planes between the different components is necessary with such a setup? We are not sure if and how we should isolate the various ground planes of these separate components from one another, as the datasheets for each component each illustrate the corresponding component operating in isolation. One possibility (among many) would be to have the following ground planes used over the board: **Power_GND** — A separate ground for power components, including the input power protection, the switching regulators mentioned above, and the DRVs. **Analog_GND** — Individual ground for each analog component directly underneath the component and on one additional layer. **Signal_GND** — A “general ground�? for all other grounds connecting to all ICs not lis

Hello St Community,I am a user of the product EVSPIN32G4. I use this board with a 4 pole pairs brushless motor equipped with hall sensors. The motor spins a large fan blade.I manage to make everything work but the start is jerky.Since version MC workbench 6.1.1 a new option has appeared for the parameters of the hall sensors: disable electrical angle interpolation. When I use this my engine starts more smoothly.I would like to know what exactly is happening, and why my startup is not good without this option. Thanks.

Hellow all,I used NUCLEO-F303RE and IHM08M1 to control my bldc motor. And used MC workbench to create my code. Motor control with Torque mode.At first It's normal but when I increase force more, motor can't keep output power. Speed and current will drop until motor can't rotate(motor will shake).​How can I keep the low speed still output same power?​Thanks
