STM32 MCUs Motor control

I am trying to do code porting of the MC-SDK software B-G431-ESC1 evaluation board from CB series to RB series. I have done it but the code does not execute, it goes to error handler. My understanding is we can do the code porting. Am i correct? Please advise.

Any FAE from India (Bangalore office) please guide for resolving it.

I have, after overcoming many hurdles, finally succeeded in getting the motor to spin up and be profiled. I didn't really need the profiling information as I already had the motor characteristics, however it helps as a double check. The thing is, neither then motor pilot nor the firmware produced by the motor control SDK can spin up the motor. The pilot tool appears to use the same settings as the firmware, for motor startup procedure, by default.I have tried re-generating the firmware, and different settings in the motor pilot, with every even slightly promising combination.The hardware must work on some level because the firmware used by the motor pilot was able to get things rolling. It did have a little difficulty starting up, but after several tries succeeded.The power supply indicates that 70mA are being drawn, regardless of whether the motor is trying to start or not, thus indicating that almost no current is being sent through the motor during the open loop acceleration phase.

The motor pilot connects ok. It tries to start the motor but fails. I think maybe the parameters that are used by the configurator are not what is indicated, for example the resistance could be phase to phase or lead to lead. Same with inductance etc. Thus, I was hoping that running the profiler would help solve the other problems I am experiencing.The terminal tab of the profiler indicates it is in fact capable of communicating with the board, things are ok there. It's sending ASPEP commands and says things are ok.When I try to connect, it adds the following entry to the log tab:[INFO] - UART worker: Successfully open port COM8 @ 1843200[INFO] - : try to configure the board[INFO] - : Connected to board[INFO] - : Disconnected from boardAny ideas?

Hello, I have done the configuration of the B-G431B-ESC1 step by step with MC Workbench. In the end I was able to control the motor with Motor Pilot. In the next step, I wanted to control the speed with an external PWM as described in the data sheet of the B-G431B-ESC1, but it wouldn't work. I checked the pin configuration and found that the PWM pin is not defined. Could you help me to control the motor via the PWM input on J3. Many thanks and kind regardsLorenz  

I'm trying to get a working motor controller out of this toolchain. I apologize that I know very little about C and embedded development, although I have used arduino, I usually use Micropython. I'm sure the answer to this is painfully obvious to some people here.I have tried many, many different driver options including SimpleFOC and some others, and I'm turning to this option out of sheer desparation, I need to drive a gimbal motor quietly at a max of about 3000 rpm. It's for an ultra quiet high pressure fan that reverses direction periodically, the openerv project. I've tried two different chips that are supposed to be no-code options, and they are unable to drive gimbal motors.Ok, so I downloaded the three tools, stm32cubeIDE, the motor control workbench, stm32cubeMX. I can configure my motor etc, I know my motor characteristics, so no need to run the parameter extraction tools. Overcame some serious errors with the process of generating the code. It appears to generate code now, b

Dear sir.I am analyzing the FOC algorithm using motor control workbench 6.10.During the analysis of the FOC algorithm, I do not understand the MCM_Clarke function part.In the case of Clarke transformation I know, it is an algorithm that converts three axes into two axes. However, at mcm, it seems to convert two axes into two axes as shown below. alpha = a beta = -(2*b+a)/sqrt(3)Maybe I can get some help?

Hello everybody,I am playing arround with the Motor Cotrol Workbench 6.1.0 with STEVAL-SPIN3204 Board.The motor is running well in the Six Step configuration with Sensorless ADC Speed Sensor Mode. If I change the Speed Sensor Mode to Hall Sensor, the Motor does not run and the Motor Pilot throws the error "Over Current". The eensor displacment is set to 120° and the electrical angle is 0°.If I turn the motor and obseve the ENCODER_SPEED variable the value is plausible. The Encoder signals measured with the oscilloscope are ok.The JP8, JP9, JP10 and JP5, JP6, JP7 are set as described in the UM2572.Is there anything else to change at the hardware to get the motor with the hall sensor working?Kind regardsMicha

Hi, I would like to launch a function automatically when my program stops after a breakpoint.I work on motor control application and it is recommanded to disable PWM channel before a breakpoint.How I do configure cubeide ? thanks for your help

I need to know about the AC current measurement for the BLDC motor. I tried to measure phase current for only one phase for two commutation states. I use the STM32F103C8 controller for controlling the BLDC motor. I need some clarification on measuring phase currents for the BLDC motor. I use Timmer 1 to generate PWM and Timmer 4 for changes that occur in the commutation state (ie Step change occurs using XOR operation) and I am using the MOSFET Rdson method to measure the phase current (AC current) and ADC2 injected method for measuring the voltage drop on Rdson.I tried to measure the phase current for only one phase (phase - B) for two commutation states(state1,state3). since the value, I get from ADC2 is varying So I tried to make an average of that ADC2 reading. I used TIM1 interrupt for PWM generation (15KHz) and for some calculations that include summing up the ADC2 reading, and the average part is done in TIM4. But it does isn't work again there is a variation in the reading. So

Hello, I'm working on Electronic Speed Controller For Sensorless BLDC Motor.I changed the ESC circuit a bit on this blog (https://simple-circuit.com/arduino-sensorless-brushless-motor-bldc/) by replacing the Arduino with a STM32F103 (I'm using an LQF48 adapter) and the Mosfet (and including the mosfet driver) using the BTN7970.I've tried the circuit that I made without BackEMF as well as testing whether my circuit can rotate 360 ° and the results rotate but the rotation is very slow (approximately 30-40 RPM).Next I tried to use BackEMF detection by using an external comparator (LM339). The result is that the motor only vibrates (the motor only moves slightly to the left and then to the right and then repeats).I don't understand what's wrong.1. Is my interrupt program correct?2.Is the program for starting the motor incorrect?Here's the circuit I made in Eagle and the STM32F103 program. int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); while (1) { startMotor(

Hello, I am trying to learn bare metal programming and servo motor control with my stm32f407g-disc1 card. I cannot move the servo motor with stm. I tried with arduino to check if the problem is in the motor and the motor worked. I thought my PWM signal was wrong and I found codes from the internet but it didn't work again. I am attaching the code and logic analyzer graphs.

Hi. I've got a sensored 14-pole motor that does 3000rpm max, but I can't get it to go past 300rpm in the MotorControl Pilot.I've confirmed its phase resistance and inductance with the ST Profiler, the VESC Tool Profiler, and the manufacturer.I've confirmed its hall sensor output with an oscilloscope. I've attached my waveforms:The motor throws me overcurrent faults when I set its max current to 40A, its correct rated current. The meter tells me I'm getting 13W when it shuts off, which is way too high but 24V/13W<<<40A.I'd really appreciate a tip, I've been fighting with this for days, now.

I have a STEVAL-PTOOL1V1 board and I can't find this board in the Motor Control Workbench v6.1.0.Could you tell me what can i do with this or why ST doesn't support this board?

Greetings Tech Gurus,I have a Nucleo STM32G431 driving an IHM16M1.Code is Generated by MC Workbench 5.4.8I am using serial communication for control from my application.I want to operate in variable speed mode.I also want to be able to adjust current limit.Everything works fine until I send a Set current references frame command.It seems like it switches to torque control mode and accelerates to max rpm.If I send an Execute ramp frame after that, it switches back to speed mode and resumes running at speed set in the Execute ramp frame.Is it supposed to switch to torque mode?Is there any way to prevent it from doing so?Thank you,-Jim

I thought my hall sensors were originally broken because I didn't see them giving a 5V signal. After replacing them, I see that new ones give at most 0.25V when in the presence of even a strong magnet! Turns out some hall sensors come with an integrated amplifier, and it's those hall sensor + amplifier IC's that give 5V. My typical reading is 0.15V high, and less than 0.01V low. Most critically, though, I've seen that there are HUGE fluctuations in the voltage output by the hall sensors depending on how close I am to the motor. I'm using a B-G431B-ESC1. Is it equipped to reliably read a 150mV hall signal? Does it have an LM393 or some other Schmitt Trigger, perhaps built into its SMT32? I've checked its user manual and found no answers. Essentially, I'm wondering if I need to modify my motor's PCB. For my custom application, I need to extend my hall sensor leads/cables by 1 meter, but I don't think my 0.2ohms of cable will make the signal much weaker. Nor do I think the signal will arr

Hi, I have a 14-pole outrunner that's rated for 30A, but I get an overcurrent error every time. That changed when I tried changing its max current from 30A to 5A. I still get two problems: 1) the motor never snaps to set speed, only oscillates about it; 2) when I load the rotor, I get a speed feedback error--I want the motor to increase torque to match the new torque demand when I apply a load to the rotor. This last point is my most important requirement.I'll add that since auto-calculation of Kp and Ki for speed control is turned on, I'm wondering if it's worth trying to tune my motor parameters (Rs and Ls)? Using a motor config wizard from VESC, I obtained different values. I multiply them by 2 because I believe VESC gives phase resistance and inductance while ST Profiler gives line resistance and inductance. This new number gives something convincing.

Electronic Speed Control Debugging? What does this setting do?

Hi, what does this mean?[ERROR] - MotorControlProtocol: ASPEP_RESP ERROR:CMD_NOKUsing MotorControl V6, motor won't start.

Hi, I'm getting some nonsense values in Motor Pilot under "MC Configuration". It says there is no max app current or voltage, and my PWM frequency is something ridiculous. I've tried changing it to 25kHz and 20kHz, and these were the readings. I've never enabled position control, either--I cannot enable position control--yet it is enabled here. If I'm correct, medium frequency shouldn't be 0, either. What's the issue?? Oh, also I get some weird warning about demagnetisation. Can't remember touching that. Included image.

Since ST Motor Control SDK 6.1.0, the Motor Profiler app has been integrated into MotorControl Workbench. Unfortunately I was unable to find how the new version of Motor Profiler can be configured and used. Wondered if anyone has used Motor Profiler 6.1.0 and could provide some recommendations ?

Using the MCSDK 5.0.1, I can startup and when I get to 2000 rpm I get Start-up failure I've tried adjusting several parameters in Workbench's 'Start-up parameters' page (attached) such as On-the-fly startup, Speed ramp duration, minimum start-up speed etc
