STM32 MCUs Motor control

When creating a new project I can not find EVAL-SPIN3201 in the inverter list. Are boards downloadable or what am I missing?

The customer was looking for a lock function from its BLDC motor driver. They were advised to use the “dynamic braking�? function of their motor driver, it seems - from what I understand. The Dynamic braking function does not offer a true locking functionality, unfortunately. Dynamic braking will allow the motor to drift from a stopped position, if the load can overcome the mechanical frictions and backdrive the motor and its transmission. Think of it as adding a lot of viscosity into a mechanism; that’s what the Dynamic Braking functionality of a BLDC motor driver chip provides. In the customer’s situation, closing the loop on position (simple Proportional closed-loop is probably sufficient in this case) would keep motor in its stopped position, even if the load tries to backdrive the motor. Application: Tourniquet. After reaching proper pressure, the tourniquet must stay in position not to allow the release of pressure. Dynamic Braking will allow a slow release of the press

I've implemented an FOC motor control algorithm from scratch (e.g. not using any libraries) and it works well. I'm generating sine waves to drive the MOSFETs via a lookup table.All this works and the motor turns in an anti-clockwise direction. How do I change the algorithm to get the motor to turn in the clockwise direction?Note: I know that reversing the wires for two of the phases will change the motor rotation direction, but I don't want to change the wiring--I want to be able to change motor rotation direction programmatically.

Hi, I have a STEVAL-PTOOL1V1 board.I flashed the board with a STLINK-V3SET with the example project "6S_STEVAL-PTOOL_HS_VM " which was generated using "MotorControl Workbench 5.Y.3".Now, I should be able to use "Motor Pilot 5.Y.3" to control the motor plugged to the board.Following the instructions on the document "um2916-mcsdk--6step-firmware-examples-insights-of-the-firmware-and-how-to-customize-it-stmicroelectronics", I am using a speed of 115200.When I try to connect to the board I get an error message saying "try to configure the board".I have two COM port available COM12 and COM13, same error with both.I previously was using a STEVAL-SPIN3204, after flashing the example project "6S_STEVAL3204_HS_VM", I was directly able to connect to the board using "Motor Pilot 5.Y.3"The only difference I can see is the stlink which is not integrated on the STEVAL-PTOOL1V1. I connected my STLINK-V3SET to the board using the SWD interface. I did not find any instructions about others connection t

The board is a STEVAL-PTOOL1V1. The setup was tried on different boards.The programmer board used is a STLINK-V3SET.I followed the instructions on the `Getting started` document of the STEVAL-PTOOL1V1.I power the board through J1 and J2 with a power supply supplying 12V. I connected J8 with a jumper.I connected the SWD pins to the STLINKS.Here is the setup and the documentation for the SWD connector of the PTOOL1V1. In order to communicate with the board, I tried:- Uploading the example project of the STEVAL-PTOOL1V1 by clicking on the debbuger icon of the CubeIDE- Clicking "Connect" in STM32CubeProgrammer- Clicking "Connect to the target" in STM32 ST-LINK Utility- Using the Open source version of the STMicroelectronics STLINK Tools : stlinkHere are the errors messages for the first three:```STMicroelectronics ST-LINK GDB server.

Hello, I want to to know how to control the Acceleration and deceleration of stepping motor using stm32mp157, I think It needs config the TIM2(for example) to one pulse mode and update the new period and enable when interrupt occurs (MOTOR_PUL_IRQHandler), but I can not find the interrupt callback function in  Kernel PWM API. is it possible to do the accurate control in core A7? or the part should be done in Core-M? if in Core-M, how to get the motor position counter in A7? that is may be another topic about the communication between core A and core M? thanks in advance.

Hi!How to make a project with a motor in the "speed control" mode without using Hall sensors, but using an incremental encoder. With a simple replacement in the "MotorControl Workbench", the properties of the motor and the properties of the speed sensor do not lead to success. In this case, there is only the initial push of the motor, then its stop and subsequent heating of the motor. Thank you in advance!

Using an input capture ch2 of TIM1 ,i want to generate interrupts at every rising edge of input signal(square wave) and call a call back function to do something.The output is is an output compare ch1 of the same timer1. Can you help me?

Anyone know the transfer function of the current sense path (shunt resisters->opamp->ADC) on the X-NUCLEO-IHM07M1? It's not worked out in the user manual and if someone has it it would save me some time.Thanks!

I am operating a low inertia BLDC Motor with the STM32 FOC Motor control library. I have modified the code to add an outermost loop that provides phase lock control to an external reference.The one limitation I have is that I think the inner speed loop has a speed resolution that is too coarse to achieve the phase accuracy I need.As example, for an RPM of 1800 the revolution is 30Hz. In the STM32 code using speed unit _001HZ, the 30Hz speed reference is 3000. I believe I need a resolution 3-4 times greater such that 30Hz is commanded with speed command 10000 for example.Are there any suggestions on how I might achieve this? Somehow I need to change the calculation of the speed to have a greater resolution. My maximum speed is not more than 2400rpm so I would not be limited by the 16-bit limit of speed magnitude variable.With the 5.Y.4 code release I can now at least look at all source code and see how things work. I would greatly appreciate all pointers or suggestions.Thanks,Brian

I want to develop a portable device, which including a PD type C power supply up to 15V/3A, and also has LCD display, BLCD motor control, and also work as an USB device(when connected type C to a PC. ).I want to develop the software based on the demo software (USB-PD_Consumer_1port ), which provided by ST. It's developed under FreeRTOS. Right now, the DC power part (PD Type C SINK)of the PCBA works well.My problem is that when I add other new tasks via stm32CubeMX(MDK ARM KEIL5) in to the project, the PD function will be abnormal, not work.Does somebody has the same solution as mine? How to add more task into the demo routine(USB-PD_Consumer_1port ), what's my mistake? Is it possible to do like this succeed?Could someone give me some suggestions? Thank you very much,Best Regards,Matt

Hi, I am working on STM32f413zh and I am referring https://www.mikrocontroller.net/articles/STM32_BLDC_Control_with_HALL_SensorIn my code shows TIM_SelectOutputTrigger() not defined. There is no definition for some timer related functions.Please give me the guidance.Thankyou

Running the ST-FOC SDK 4.3 for our PMAC motor with an outer speed loop and running at constant speed, we see that there is a trade-off between having good torque and good flux regulation. E.g. increasing the P term for the torque controller will decrease the noise in torque, but increase the noise in flux. I know there is a cross-coupling term that can be influenced by feedforward control, but we have not yet implemented this feature because we expect to see only minor positive effects from it. Please correct me if we really should be able to independently decrease the noise to a high degree, with or without the feedforward control. Otherwise, what are the pros and cons of having really small torque errors but large flux errors and visa versa ?

My motor can spin with profiler and MCWB, it's sensored so I don't need to setup the startup parameters, then generate the source code and import into CUBEIDE, copy the MCWB generated PID Gains values, build and debug, suppose if I press the little SW1 button, it will spin, but unfortunately NOT ! I can use on-board's potential meter ADC as hFinalSpeed value for MC_ProgramSpeedRampMotor1() command.I can make small I-PMSM single pole pair motor spin, however when replace with bigger motor e.g. 6 inch 6 pole pair SM-PMSM motor, I couldn't make it spin and strange thing was when I increase hFinalSpeed value, motor not start or spin  can anyone help to point out which parameters I should focus to ?  Hardware : G431-ESC-1 boardMCSDK : 5.4.8 (version 6 could not connect with G431-ESC with UART)Motor : Pole Pairs : 6Max.

Hello,I'm doing a project where I control a DC/Stepper motor with an stm32 MCU. I'm using an I2C Motor Driver to connect between the controller and the motor.The Motor Driver isn't compatible with stm32, therefore I need to write a software library for it.If you know any literature that can help me write a software library to control a motor that would be very helpfulThank you

STMCWB v.6.0, Motor Control WorkBench, project name - 6 step kit: Can I to change from NUCLEO-G431RB to NUCLEO-G491RE as control board? What should I do in order to use NUCLEO-G491RE ?

I'm using an STM32 to control a DC motor with a dual hall encoder feedback.To monitor motor position I want to use a General Purpose Timer (16bits) in Encoder Mode.As my input is noisy, I want to filter the signal using the Input Capture filter.My problem: I don't find any information about the ICTimer.Here's what I found in the AN4013 - STM32 cross-series timer overview Application note> "Program the filter by writing the IC1F[3:0] bits in the CCMRx register, and the prescaler by writing the IC1PSC[1:0] if needed"What kind of filter is this?How do I choose the value for IC1F?What is the cutoff frequency?Your help is appreciated.

Hi!There is such a document: "AN5464-Positional control of a three‑phase motor with permanent magnets using X-CUBE‑MCSDK or X‑CUBE‑MCSDK-FULL"It describes the method of setting the PID controller. It is necessary to reset all coefficients and gradually increase the P-component in order to achieve its fluctuations. Question: Before that, do you need to set the motor to the zero position or to another angle? or how was CubeMX created and compiled?Thank you in advance for your help!P.S. I can't configure the PID controller. The best thing that happened was the shaking in the set positions, and the engine is very warm!Tell me what to do?
