STM32 MCUs Motor control

Hi, I am using the code below to spin my brushless DC motor. When I used another code where I have a potentiometer to vary the motor speed, the motor spins without problem so I don't think the DC motor and ESC are faulty. Is there something wrong with my code? Am I starting the PWM at wrong time?I have checked the PWM generated by this code. The signal is there.main() function:int main(void) { /* USER CODE BEGIN 1 */ char data[20] = { '\0' }; uint8_t controller_cnt = 0; // default is P controller char controller = 'P'; uint8_t row = 0;   const uint8_t coef_origin[3] = { 11, 2, 10 }; uint8_t coef_loc[3] = { 11, 2, 10 }; /* USER CODE END 1 */   /* MCU Configuration--------------------------------------------------------*/   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init();   /* USER CODE BEGIN Init */   /* USER CODE END Init */   /* Configure the system clock */ SystemClock_Config();   /* USER C

 Is st mc sdk support measure the motor parameter only use the board, not use STMotorProfiler?It is useful to driver different motor when the foc board used as a general driver product.

I mean the eval board foc source code., not the sdk. I searched on the st website, but find none.In the pc directory "STMotorProfiler\resources\assets\fws", I found the firmware, like as NUCLEO-F446RE#STEVAL-IPMNG3Q 3Sh#(5.4.0)#(3A1B794F).hex, but I need the source code. Someone can tell me where to download the source code?

Hi,I have one TMOTOR RI-70 KV95 BLDC motor with HALL sensors and harmonic grive gear 1:120 and payload 10Nm controled by evalkit NUCLEOG431+X-NUCLEO-IHM08M1. I need to control it in torque mode.I generate application in MotorControl 5.4.6, FW 1.1. Without payload all setup works well, but when payload is attached, I have strange for me problem.When value of "placement electrical angle" is set to 60 degree in MotorControl.Starting position is 6 o'clock (arm hang to down).In generated application I execute: MC_ProgramTorqueRampMotor1(2000, 1); MC_StartMotor1();Afer moving arm to 9 o'clock or 3 o'clock arm is blocking. Blocking is minning, that when I change torque value to 3000 or 4000 (in debug mode), motor start ticking by 1 hall position and after few (10-30) seconds of ticking motor start moving smoothly again.When I set "placement electrical angle" is set to 90 degree in MotorControl. This issue doesn't appears in CCW direction, but in CW direction motor is not moving well at all.W

Take the 1st sector as an example,Tim1 is configured in center-aligned mode,in function PWMC_SetPhaseVoltage Ta,Tb,Tc is figured out,then TIM_CCR1~3 are set to Ta,Tb,Tc.But in my opinion,TIM_CCR1~3 should be set as below.What do I get wrong?

Hello! I'm trying to write the "fastest as possible" code for a 3P3Z (3 pole, 3 zero) controller, but even with SIMD32 instructions, the C code+compiler optimizations seems to win this battle.Here's the C code:static __INLINE int16_t q15_cntrl3z3p(q15_3z3pStruct_TypeDef_t *controller){ q63_t acc; /* Accumlator */ q31_t fcurr; /* Variaveis temporarias */ // y(k) = u(k) * g0 + u(k-1) * g1 + u(k-2) * g2 + u(k-3) * g3 //  - y(k-1) * h1 - y(k-2) * h2 - y(k-3) * h3; controller->umem[0] = controller->setpoint - controller->input; acc = (controller->umem[0]*controller->gCoefs[0]<<controller->gShifts[0]); acc += (controller->umem[1]*controller->gCoefs[1]<<controller->gShifts[1]); acc += (controller->umem[2]*controller->gCoefs[2]<<controller->gShifts[2]); acc += (controller->umem[3]*controller->gCoefs[3]<<controller->gShifts[3]); acc -= (controller->ymem[1]*controller->hCoefs[1]<&l

I want to implement sensorless FOC with B-G431B-ESC1 Discovery kit.But i don't want to use motor profiler as it's not profiling my motor properly.Is it possible?

Hardware: NUCLEO-F303RE + X-NUCLEO-IHM07M1Software: MCWB 5.Y.3 + STM32CubeIde 1.7.0Motor combination: 200142 + 166935 + 673026 (12V + 21:1 + 1024CPT) Project requirements: minimum speed: 0.4 RPM max speed: 3000 RPM (motor speeds NOT gearbox output) I have managed to create a project that sort of works. At this stage I would like to achieve the best performance possible, when creating a project I have guessed the values but now I would like to know if these values are even reasonable? Does anyone know how to select the PWM frequency and other parameters? is there any formula to be used? or any documentation? Thanks in advance Kind RegardsManpreet Singh

Hi all,Over the past few months, I have been using the motor control SDK to develop a custom high efficiency motor controller for my university solar car team. After spending a while getting my hardware working and debugged, I am working on custom firmware for implementation in an EV and have compiled several questions regarding braking.My primary background is actually in mechanical design and electrical hardware, so I am still learning the firmware side as I work through this project. As such, it would be great if you could provide "step-by-step" answers for any of the questions below! I have taken a motor theory coarse so I am fairly comfortable with the concepts of FOC.Context: As this is for an EV application, I want to be able to implement regenerative braking for maximum efficiency. For this, the driver has an additional pedal (in addition to a standard mechanical braking system) which will be used for motor braking. My goal is for the pedal position to control the percenta

Going over the application notes, I see that VCC provides many option but with minimum of 8V (default). I need 5V to supply my encoder and the line driver.Should I just use a voltage divider to VCC and get my 5V out of it? Sorry if I am answering my own question, but I want to make sure. Should I also filter the power with capacitors? Any suggestions will be appreciated.

HiI am trying to download the code to STEVAL SPIN3201 form IAR IDE. But i am getting an error (6S_STEVAL3201_SL_VM.out file not found or corrupted) while downloading.Please can you help me to solve this issue. What I am doing wrong ? Please follow the image.

hello, I am using P-NUNCLEO-IHM001 package(nucleo-F302R8, STSPIN L6230 motor driver, BR2804 motor 1700kv-1) to performance FOC algorithm. But i did not find Parameters of the motor, could someone let me know where can i find the datasheet or Details of parameters of the motor. thanks

I am planning to us the STM32F103 MCU for BLDC motor control. No encoder, only the usual three Hall sensors. I am attempting to use the XOR gate in Timer channel 1 that combines the rising and falling edges of all three Halls (Ref. Manual RM0008, page 332). See the enclosed diagram, where the red lines indicate the signal flow used for this feature (Ref. Manual RM0008, p. 382, Fig. 125). Question: how is the Timer's Edge Detector configured to detect both rising and falling edges? I cannot find a reference for timers. (only for external triggers - ETR). Thank you for your feedback!

Hi @Camilo LEMOS​ I had to start a new thread, as you've closed the announcement (which is a strange thing to do in a forum).I went for the whitepaper to find out it requires a rather annoying registration procedure. Why can't we use our my.st.com/community.st.com account for this? When complaining about annoying login procedure we repeatedly receive the answer that you want a single point of registration, so why aren't you consistent in this?Jan Waclawek

I used the example from Motor control work bench(ElectronicspeedControl),configured CAN in CubeMX and imported generated code in STMCubeIDE.Now I don't know what should be next step?

I am trying to run the example from motor control work bench for B-G4314-esc1 Electronic speed control.I generated ElectronicSpeedControl.stmcx and generated code in cubeMx.Now when i try to load the configuration in CubeIDE it is showing me error in motor control in initial build.

Hi, I am using B-G431B-ESC1 board for tests and MC-SDK 5.Y.2. I have a motor with Hall sensors. Are there any possibilities for braking the motor other than setting a downward speed ramp to 0.I mean regenerative braking methods, and I'm also wondering if it is possible to keep the motor in place at zero speed despite attempts to turn it. Without using an encoder and position control, namely with Hall sensors and current measurements.Perhaps this is outside the scope of the MC-SDK, but I would still like to know the possible options.

Hi everyone,I am unable to start a Maxon "EC-max 30" BLDC motor (ref 272766) with "NUCLEO-L476RG" development board & "X-NUCLEO-IHM08M1" expansion board using "MotorControl Workbench 5.Y.2" and its corresponding "Motor Pilot 5.Y.2".First of all, the hardware setup of the expansion board was done for FOC control in 3-shunt current sensing topology according to the user manual "UM1996" as well as the motor profiler configuration guidelines (for both the development and the expansion board).For info, the motor parameters could not be identified using "Motor Profiler 5.Y.2" tool as it tries to draw too much current and the identification process could not be finished, so the motor parameters were taken from the datasheet.As for the MC workbench software:The bus voltage sensing, temperature sensing, current sensing, over-current protection and power stage parameters were taken from table 7 of the user manual "UM1996".The parameters of the motor and its sensor were taken from their respe

HelloI am new to STM32. I want to Use FOC for controlling sensorless motor. Which MPU/MCU can be used for ESC of drone motor. I found STEVAL-ESC001v1 can be used as reference design for entry level commercial drone design. Which software I need to download and only ordering ESC001v1 will be sufficient to start project? or is there necessity to order other board?

Hi All,I am presently measuring the two signals below through a multichannel adc that is triggered by the rising edge of a PWM signal on TIM1 CH4.a. Inverter return line current on channel 3 b. Speed reference value from a potentiometer.I am quite sure, I am reading the right adc channel, but the problem is that the adc value for the current seems to be corrupted and it jitters too much from the correct value. Below is the configuration code for the ADCstatic void MX_ADC_Init(void) {   /* USER CODE BEGIN ADC_Init 0 */   /* USER CODE END ADC_Init 0 */   ADC_ChannelConfTypeDef sConfig = {0};   /* USER CODE BEGIN ADC_Init 1 */   /* USER CODE END ADC_Init 1 */ /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */ hadc.Instance = ADC1; hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc.Init.Resolution = ADC_RESOLUTION_12B; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc.Init.ScanConvMode = ADC_SC

I got the MCSDK example working, but how can i go further?Can i write custom code that controls the motor without Motor Pilot?[STEVAL-SPIN3201 // maxon BLDC motor]

Hi Community, I am using STM32F030C6 MCU for project. In Motor control workbench I couldn't in find the controller in that tool. But STM32F030R8 controller is available. So some help me to procedure for migrate project from STM32030R8 to STM32F030C6 or build motor controller application using MotorControl Workbench toolThanks Kalaimani Arumugam
