STM32 MCUs Motor control

System Details:MCSDK Version: 6.4Tool: MC Workbench 6.4.0Control Board: B-G431B-ESC1Motor: GL40 KV210Encoder: AS5047P with quadrature outputHello,I'm new to BLDC and FOC motor control and am currently trying to implement speed control using a quadrature encoder with my B-G431B-ESC1 board and GL40 KV210 motor. I've reviewed the manual and various forum posts regarding similar issues, but haven't found a solution.My primary problem is that while the setup functions correctly in sensorless mode, open-loop voltage, and open-loop current modes, encoder-based speed control is not working. Interestingly, the speed and direction calculated by the encoder align with the estimates from the sensorless approach.I suspect the issue lies with the encoder alignment process. I've observed the `stopll_el_angle` and `enc_el_angle` plots before and after alignment (as shown in the attached picture). During the alignment process, I plotted `I_q_

I want to enable the UART communication in MCSDK software which is very time critical task, i enabled UART with DMA, the problem is it cannot transmit more than 2 bytes even if i give 3 or more for transmission HAL_UART_Transmit_DMA(&huart3, buffer, 3); I get the call back  void HAL_UART_TxCpltCallback(UART_HandleTypeDef *huart) { uartransmissioncomplete = true; } after every 2 bytes.  I tested the same program only with UART it works fine transferring more bytes. So, can i just go ahead with transmitting 2 bytes for every call back function, or will i really be able to transfer more bytes in the complete project, since i don't want to disturb the main functionality, i want UART data for data logging. 

Hello, when I was running the code generated by SDK6.4.0 on STM32G431CBT6, I found that my motor was not working properly. So I grabbed the PWM output generated by Timer 1 and I want to know what caused this

Hello,I am working with a BLDC motor in sensorless mode using ST Motor Control Workbench and Motor Pilot.When I press the Start button in Motor Pilot, the motor status changes to Running based on the target speed I set, but the motor shaft/wings do not actually rotate.Additional observations:The motor is not in a locked condition (not drawing stall current).If I try to manually rotate the motor during startup, it still does not continue spinning.On Motor Pilot, the motor state shows Running, but physically it is stationary.My Questions:Why does the motor state show Running while the rotor is not moving?How can I debug this issue further to ensure proper startup in sensorless mode?Any guidance or suggestions will be greatly appreciated. Thank youBest R

您好，我已经在STM32G431上成功配置了 6.4.0 SDK 包。 但是，当我按下按钮并开始预充电过程时，报告了硬件故障。 如果我在预充电过程中将上侧 PWM 波的刻度值从 0% 更改为 90%，程序将在 RUN 后进入 STOP 状态，然后进入故障状态。故障代码为 40，定义为 #define MC_BREAK_IN （（uint16_t）0x0040） /**< @brief 错误：紧急输入（过流）。 */ Post edited by ST moderator to follow the community rule which is using English language. So in next time please use English as it's an international community and to let others to understand your post. Thank you for your understanding. Translation: Hello, I have successfully configured the 6.4.0 SDK package on my STM32G431. However, when I press the button to initiate the pre-charge process, a hardware fault is reported. If I change the duty cycle of the upper PWM waveform from 0% to 90% during the pre-charge process, the program enters a STOP state after running, and then enters a fault state. The fault code is 40, which is defined as #define

Hello,I am working with the STM32F303E-EVAL control board and the STEVAL-IPMNM2S power board, using IAR Embedded Workbench 9.40.I have struggled to get the motor running. I initially tried both MCSDK versions 9.3.2 and 9.4.0 separately, but in most cases, the motor either does not rotate or runs with excessive noise — overall, it fails to operate with error.However, on one occasion, I accidentally recreated a project using MCSDK 9.3.2 and then rebuilt it using 9.4.0. Surprisingly, that build worked — the motor rotated smoothly, and I was able to Motor Pilot control speed and torque successfully.Since then, I have tried many times (over 100 attempts) to reproduce the same working setup using both versions, separately and in combination, but without success. The motor fails to start or runs poorly.Could someone please help me understand what might have gone right in that one successful attempt and how I can reliably replicate it?Thank you in a

Hello,I had the motor profiling experience to get motor mechanical and electrical parameters using EVSPIN32G4 boardsas following:Now I'm trying to start the project for controlling a new high power motor with EVLSERVO1 board. But, I couldn't find the ST provided firmware for EVLSERVO1 board as listed this.  

Hi all,I’m currently using the EVSPIN32G4 development board for a drone project. I’m controlling motor forward and reverse using ST Motor Pilot.I’ve noticed that when switching from forward to reverse, there’s a short pause before the motor starts spinning in the opposite direction.Is there a way to implement a seamless transition between forward and reverse motion so that the motor can switch direction without this stop?Thanks in advance for your guidance!

In the STSPIN32G0601 device, the stm32g031 controller core has internal connections to complementary gate drivers. The outputs from the stm32g031 that can be configured with alternate function complementary signals (PA7, 8, 9, 10, PB0 and 1) are not used though.  Internal connections in the STSPIN32G0601 are PA8, 9, 10, PB13, 14, and 15.  I need to program a 3-wire, 2-phase signal that has a pulse frequency of 3,840Hz.  I can do this with 3 separate output compare interrupts with each interrupt service routine writing to 2 pins.  This is cumbersome compared to using the timer peripheral's PWM capabilities which are not available due to internal signal wiring.  I have found nothing in the MCSDK development software that addresses this; so, I am coding in STM32CubeIDE.  MY QUESTION IS:  am I overlooking a simpler way to approach this?

Hello,I am running a BLDC motor in sensorless mode using Nucleo-F101RE with the X-Nucleo-IHM16M1 board. The motor starts successfully when I press the Start button from the Motor Pilot GUI.However, I am facing the following issues:When I suddenly increase the speed to high RPM, I get a speed feedback fault.When I suddenly decrease the speed, I also get a speed feedback fault.Sometimes I also encounter an overvoltage fault during these speed changes.Any guidance on how to resolve or tune the parameters properly would be very helpful.Thank youBest RegardsRahul

Hello,I’m testing a motor with integrated Hall sensors for which I don’t have the datasheet and that I can’t disassemble. From the tests I’ve done, it appears to be a 4-pole motor with Hall sensors spaced 120 mechanical degrees apart.I first tested the motor in voltage mode without using the Hall sensors: it runs smoothly, doesn’t overheat, and spins correctly, so the pole count seems right. Then, I moved jumpers 5, 6, and 7 to connect the Hall signals to the microcontroller, powered them at 5 V with jumper 3, and checked the H1, H2, H3 sequence with an oscilloscope. The signals are present and in sequence.However, when I try to start the motor, it needs a manual push to get going and then it immediately ramps up to maximum speed. Also, I don’t see any speed feedback on the Motor Pilot, and I can’t change the target speed. If I try enabling polling of HALL_SPEED or HALL_EL_ANGLE from the registers, I get the following log error:[WARNING] - MotorCon

Hi everyone,I'm working with the STM32F446RE and exploring the 6-step BLDC motor control example provided by the STM32 Motor Control SDK.

Hello，I am using MCSDK6.4.0 on STM32G431CBT6 for motor drive development.The generated code runs without any modifications. When using the Motor Pilot tool to start the motor,the chip crash, and there is no change in the motor. Debugging reveals that the program randomly enters NMI_Handler,HardFault_Handler, and FMAC_IRQHandler when starting the motor (after entering FMAC_IRQHandler several times during the first programming run,it does not enter again). I am using STMCubeMX 6.3.0. The chip's power supply is measured to be normal, and no reset has occurred.Below is a screenshot of the interrupt entry. What is the cause of this issue, and how can it be resolved.

Hey STM community,I have a G431RB & IHM16M1 however whenever i try to run the motor pilot, i cant seem to connect to the board. I  have made sure all the necessary link drivers are installed, i have made the baudrate  115200, 8bit all to match up with the software but i consistently get no connection. My cube ide, motor workbench and motor pilot are all up to date and i have the associated packages( the G4 library v1.61) installed in cube-mx.Thanks
