STM32 MCUs Motor control

I want to configure dead time between different channels but I get the output as in the picture.Below is the PWM function I created for the BLDC motor and algorithm for each phase of BLDC motor. What could be the problem?  void BLDC_SetPhase(uint8_t phase) { switch (phase) { case 0: // AH = 1, AL = 0, BH = 0, BL = 1, CH = KAPALI, CL = KAPALI HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1); __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1, 50); HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_1); HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_2); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANNEL_2); __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_2, 50); HAL_TIM_PWM_Stop(&htim1, TIM_CHANNEL_3); HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_3); break; case 1: // AH = 1, AL = 0, BH = KAPALI, BL = KAPALI, CH = 0, CL = 1 HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1); __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1, 50); HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_1);

Hi,R3_2_TurnOnLowSides is shorted motor 3 phases to ground, so when my ebike is downhill will motor power will transfer to DC BUS so call regenerative braking ?Danny

Currently, I am using FOC control in MCSDK for position control, and the speed graph appears as shown in the attached figure when the motor moves to its target position. However, I want to achieve control where the motor maintains its maximum speed for as long as possible. No matter how much I adjust the PID coefficients for position control in MCSDK, the result seems limited to the attached graph.Is there any way to achieve this?The speed graph I want looks like this. Thank you.

Hello,i am beginner in ST motor control domain.I have installed the following software versions :MC workbench v6.3.2CUBE IDE v1.16.1CUBE MX v 6.12.1I have a problem when trying to connect my board using profiler. In log, i can see the last two messages :UART worker: Succesfully opn port COM8 @ 921600Try to configure the board And the process stop here.Precisions :The STM32 has been full erased previously with Cube programmerProfiler is the only tool connected to my board when i am trying to make the connection with profilerWith Cube IDE as well.Can you help me ? I have spent several hours looking for solutions but i'm still stuck.Best regards

Hello,We have a 5 pole pair magnet rotor and we have been using STEVAL-CTM009V1 development kit along with NUCLEO-G474RE development board.First, we did a preliminary testing with a sensorless control (observer+PLL) and after understanding the aspects of the Start-up Profile under Sensorless Startup Parameters in Workbench we got the motor to spin smoothly although the start was a little jerky and the direction of rotation wasn't consistent but took of quite well after 50rpm all the way upto the defined speed.Second, we now tried to spin the motor with Hall sensor as Speed Sensing Mode and clicked "Start" button under the Control from Motor Pilot. While there was about 0.14A of current drawn from the power supply when we started the control, absolutely no action in the Motor. Waited for a while, before stopping or resetting the operation, and rotated the rotor manually by hand and now Speed Feedback Error showed up. Obvious to note, the motor still didn't spin. Just so you know, we got

I am trying to control BLDC motor with Steval IPM30 B and Nucleo L476RG as controller. In sensor less mode it is working fine but when I am using Hall Sensor it is not rotating at all and its showing speed feedback error at the starting only. How to solve it.Also what will be the switch configuration in Hall Sensor circuit in IPM30B.Which switches should be ON .Looking forward to your response.

My goal is to connect 2 internal PGAs to 1 ADC (especially ADC2). I configured in CubeMX and generated source code.   However, when I checked the ADC channel initialization code in IDE project, I could see that only one channel is activated in ADC2. /** * @brief ADC2 Initialization Function * @PAram None * @retval None */ static void MX_ADC2_Init(void) { /* USER CODE BEGIN ADC2_Init 0 */ /* USER CODE END ADC2_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC2_Init 1 */ /* USER CODE END ADC2_Init 1 */ /** Common config */ hadc2.Instance = ADC2; hadc2.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc2.Init.Resolution = ADC_RESOLUTION_12B; hadc2.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc2.Init.GainCompensation = 0; hadc2.Init.ScanConvMode = ADC_SCAN_DISABLE; hadc2.Init.EOCSelection = ADC_EOC_SINGLE_CONV; hadc2.Init.LowPowerAutoWait = DISABLE; hadc2.Init.ContinuousConvMode = DISABLE; hadc2.Init.NbrOfConversion = 1; hadc2.Ini

i have B-G431B-ESC1 board and motor. I can not profile this motor. X-CUBE-MCSDK-6 have issue that when i wrote max speed for example 30 000, my motor is go up to 3 000 which is 10% of max. In order to solve this issue i am using X-CUBE-MCSDK (version 5). I can wrote there 300 000 (cant in X-CUBE-MCSDK-6), so my motor can go up to 30 000. But when i do that, my profile wont finishing. It gives error like it take too time...I need advice

Hello, I use the EVSPIN32G4 to test some brushless motors. On ST motor workbench there is an option called: Quasi-synchronous rectification in PWM generation.There is nothing on the board documentation about it. I'am quite familiar with both synchronous and asynchronous rectification for brushless half bridges but i found nothing on the "Quasi-synchronous rectification".Can you help me?Best regardsFlavien

Hello,Is there a way to get schematic reviewed without sharing it publicly? My company doesn't allow public posts, so wondering if there is any possibility private reviews. Thank you!

I am trying to implement a Phase Locked Loop in a microcontroller STM32. I have a reference signal and feedback signal which has $\phi$ difference wrt reference signal. For the moment, I am not using a real time feedback signal, rather simulating it inside the microcontroller itself, but later extend this to Real time.  1. I have a timer interrupt to generate a reference signal where sampling rate = 100KHz, and the target frequency = 1KHz.  2. I used a DDS inside this timer which has a phase accumulator and a LUT for both reference and shifted sine.  3. In the beginning when no control loop is running, the ref and feedback would be generated.  4. now I implement a PLL, for that I have a multiplier phase detector and i use averaging integrator to remove the higher frequency components to get error.  5. Here, I also implement a PI control loop which runs at a slower clock rate compared to the timer interrupt. so I take for example, 50*1 sine period steps. I send

Hello everyone, I'm working on a motor control project using an STM32 microcontroller (TIM1 and TIM8 timers), and I need to implement a soft Break to safely stop the PWM signals with proper transitions (respecting Dead Time and setting the outputs to 0V in low-impedance mode). However, the methods I've tried so far don't seem to work as expected. Here's what I want to achieve: When stopping the motor, ensure all PWM outputs go to 0V in low-impedance mode. Respect the configured Dead Time during the transition to avoid cross-conduction. Optionally, use a software-triggered Break (TIM_BDTR_BKE) to achieve this cleanly. My Current Setup Initialization Code (PWM Start):           HAL_StatusTypeDef motor_pwm_init(uint8_t motor_i) { HAL_StatusTypeDef status = HAL_OK; TIM1->CCR2 = VALUE_MAX_TIMER_PWM; TIM1->CCR1 = VALUE_MAX_TIMER_PWM; TIM8->CCR2 = VALUE_MAX_TIMER_PWM; TIM8->CCR1 = VALUE_MAX_TIMER_PWM; if (motor_i == MOTOR_1) { status |= HAL_

Hi all,I have adapted the B-G431B-ESC1 board into a custom design and I am using a STLINK-V3MINIE for programming. I can program the controller and I can communicate via the serial interface.But ST Motor Pilot V1.2.12 does not detect the UART interface. The 'Board Connection' area is greyed out. I tried older versions of the MotorPilot but it did not work too. Can ST Motor Pilot not work with STLINKs or do I need a different one than the STLINK-V3MINIE? Kind Regards Thundernail

HelloI'm trying to figure out how to detect a phase loss on the motor side. I'm looking for a distinction between "loss of one motor phase" and "loss of all motor phases". This can be recognized quite well from the currents measured using the ADC. However, it turns out that if you only sample two currents, it looks as if all three are missing for a certain motor phase. Now I'm looking for a way to differentiate here. If one of the other two motor phases is missing, the measurement is clear. Is there an approach on the part of ST? Can the ADC be reconfigured so that it doesn't just sample 2 phases? Best regards  

hi everyone,I cant see usage of MCI_SetCalibratedOffsetsMotor or MC_SetPolarizationOffsetsMotor1 in example project, but code comment says use at least one time in product life. Has this been used before? or  "MCI_StartOffsetMeasurments". does anyone have  code example from scratch for  commissioning a motor. 

Hi I am using this board ''2500 W motor control power board based on STGIB30M60TS-L SLIMM™ 2ndserie IPM'', to control the induction motor. However, I face some challanges especially with shunt resistors. These resistors get burnt out easily if there are any spikes or noise in the system. Also, when the SD pin triggers due to the noise, it is impossible to turn PWM for IPM, although the SD pin is deactivated after awhile. In the manual of this board, the RC filter is mentioned as being placed to prevent short circuits due to noise on the shunt resistor. These RC filters are R23, R18, R21, R24, and C19; however, R18, R21, and R24 are not used on this board. So, I am planning to use external current sensors instead of these shunt resistors. My question here is, ''Is it possible to remove/bypass these shunt resistors and use external sensors instead?'' 

I have attempted to interface an STSPIN32G0601 using only connections to an ST-LINK (V2).  That is: there are no other connections to the target IC other than SWCLK to PA14 (pin 62), SWDIO to PA13 (pin 61), GND to VSS (pin 8), and 3.3V to VDD (pin 7).  The STM CubeProgrammer application sees the ST-LINK device, but it does not detect the STSPIN32G0601.  I have none of the pins other than the ones I've already mentioned connected - no powers, no grounds, no pull-ups, no pull-downs.  I am trying to decide whether I have a bad device or do not have sufficient connections to allow communications through the ST-LINK.  The ST-LINK has been verified to work with a number of other STM32 boards.  Is my minimal configuration sufficient?

Hi everyone, I am seeing  MC library doesnt support Position/Speed/Torque Mode in same application. Is it true? Or library support but user app functions are produced for spesific mode? 

I created a project using EVSPIN32G4-DUAL to test the two motor drive combination provided by ST. Then, the following error message was output. Generate ProjectWarning! Hardware changes must be applied to the following signals. Please, refer to the board diagram for details.PinSignal nameHelpPA7 CURRENT_SHUNT_P NOTICE: Please disable the overcurrent protection of Stage 2 to avoid resurce assignment conflict on COMP2.

The power stage is already protected by STDRIVE101. M1 and M2 use COMP2 as a comparator for overcurrent protectionM1 and M2 use the same COMP2, but the pins are set differently, so an error occurs.  Does anyone know of a 2 motors combination with one G431?

I want to create a project with the Motor Control library using CubeMX. However, The Motor Control library is not registered as a software package in CubeMX, Now. Refering some application note, it says to use CubeMX's X-CUBE-MCSDK, but this software package is not available in CubeMX. I wonder if the X-CUBE-MCSDK software package will be available again in the future.

I have a project that requires Implementing a PID into controlling an DC motor (H-bridge), but im currently stuck on the code and other implementing stuff that i need help of. The desired Speed can be adjusted using the potentiometer, and the tachometer data sheet reads each volt equals 1000rpm. So im stuck here on whether to count the Tachometer as a timer or as ADC ? and im trying to figure out a good code, which i have written some of it that helps me achieve this, and exactly where to put the code of the PID ? If any of you can help i would be so pleased.    

I am working on ACIM driver.I am using NUCLEO-G431RB and STEVAL-IHM023V3.I am working on VF-OL example. I can not read the current values (Ia, Ib, Ic) on the shunt resistors. How can I read it?

  Hello, I've tried to post a question in the motor control forum section, but probably with this special case, which is basically sine wave generation, I should have posted here. It may sound crazy, but for minimum motor vibration and most smooth pulling around the revolution of the motor, I'm using Analog Devices DDS chips to create 2 or 3 (depending on the motor, 2 with old sync motors, 3 with new 3 phase motors) sinewave in precise controlled phase shift in between the outputs. It is small series and the last version I made at 2011. Now, I want to make a new version. I'm new to STM32, was using mainly 8bit PIC controllers. I read that it is more than possible now with more modern controllers to put the DDS(s) into the uC and use DAC output to put accurate sinewaves out. Would you please where to go forward? What controller should I choose and if there is any library, appnote etc. I can start with? Maybe motor control is not the right place to ask? For sure, normal switching of

I am referring to the B-G431-ESC1 source code and i feel there is an error in the battery voltage measurement source code. A conversion factor is used to convert from the ADC voltage to the battery voltage. It is initialized as followsRDivider_Handle_t BusVoltageSensor_M1 ={ ._Super        = {  .SensorType     = REAL_SENSOR,  .ConversionFactor  = (uint16_t)(ADC_REFERENCE_VOLTAGE / VBUS_PARTITIONING_FACTOR), }, The voltage is read in u16Volt format when reading the ADC register value , I assume the adc driver will only give max value of 12Bit (4096) for 3.3V, but where is this conversion added to convert to Battery voltage. Please advise.
