STM32 MCUs Motor control

[VERSION]: 6.3.1[TOOL]: Board Designer, Motor Pilot, MCSDK[DETAILS]: Created custom board based on IHM16M dev kit, using STM32G431RB + DRV8323. Motor Pilot cannot spin motor, but encoder signals look accurate, Vbus signal is accurate, and current sense signals look correct (albeit very low).[EXPECTED BEHAVIOR]: All pins of custom board match IHM16M dev kit. I am trying to spin the motor with Motor Pilot but the motor does not spin.  I can see pwm on the motor phases but no motor movementI double checked my pinout vs IHM16M dev kit:My custom board: IHM16M pinout with default project:             The motor driver circuit I'm using with the DRV8323 I've been using for over a year now so that circuit must work minimally as expected.  As I mention above the encoder seems to be working well.  And PWM seems to be happening but the motor is not spinning at all.I've tried changing gains to be much more aggressive but that doesn't seem

Dear all,Background: I am in a student project trying to build a robot for RoboCUP - SSL. We have elected to go with DF45L035048-A from Nanotec. I have not received the motors but I saw that it is possible to import a new motor with a .json file. I know the specifics of the motor (from the datasheet) but I do not know the format of the file.Question: Is there a template for the .json file that I can use which MC Workbench6 will accept so that I can started even though I do not have the motor?Kind regards

I have an A2212 13T motor with B-G431B-ESC1 with  6-step trapezoidal algorithm.It is tracking the speed reference input.But the problem is that it takes time to reach the desired speed.Suppose currently my motor speed is at 5000 rpm, but if I change the speed to 8000 rpm, it takes time to reach that speed.How to overcome that problem? 

Hi there.Im using ST motor control work bench version 6.2.1 using STEVAL-SPIN3201. sometimes when i start motor  MCI_State_t doesnt show correct status, Motor is not spinning but MCI_State_t  shows motor is spinning (MCI_State_t =6). this also happens in motor pilot, my motor is in stall condition and motor pilot shows no fault. even shows target rpm is acheived.

Hi, I recently tried SDK 6.3.0, 6.3.1, and 6.3.2. The Board Designer tool is the best for me. It's pretty cool and nice. With this tool, I can easily design the board for motor control. However, I would like to know the reason for adding the feature of PFC to this tool. All the MCUs are showing as "PFC is not supported". Does that mean the "PFC" feature is not available to use or am I missing out something on it? If this "PFC" feature is not available to use in SDK6.3.X, what is the reason for adding this feature in the Board Designer? I also tried to find it in the released note but I saw nothing regarding PFC.  Thanks and regards,Agga Min Khant

I'm trying to make a custom board project with Board Designer and found the documentation lacking for entering the correct parameters. The Bus Voltage Divider needs to be equal to 1/(voltage divider ratio). Also, the resistors on the Board Designer are not labelled so I had to guess and reference the wiki. So for me using a 51k and 4.99k voltage divider I needed a Bus Voltage Divider value of 11.223344V.  This number doesn't make sense to me as an engineering value. There's also no direct documentation for calculating this value either.  From the wikihttps://wiki.st.com/stm32mcu/wiki/STM32MotorControl:Motor_Control_Boards_Description#Bus_voltage_measurement   After calculating this value the bus voltage readings are accurate for me.

I am planning to purchase a BLDC motor drive from ST. I have shortlisted EVALSTDRIVE 101 and Nucleo F446RE. There is a lack of clarity on how this two boards are connected together. Should I purchase X-Nucleo-IHM09M2 or something else

Hello I am currently doing a project that require to control a BLDC motor with an STM32 MCU card.I will first state the list of all the materials that i have, the goal of the project and then talk about my problem.For this project i have : - Nucleo-F411RE- Driver mosfet LF2388B- Three phase full bridge MTI85W100GC- BLDC motor ECI-63-60-K1and i'm using STM32cubeIDE software. The goal of this project is to control the BLDC motor with the nucleo card. First I detect the position of the motor, then I determine wich phase the motor is and then rotate to the next phase, and regulate the speed with the current sensor. My first approach was to generate six PWMI'm using the pin like that :   PB9, PB8, PB6 == position sensor for the motorPA1, PA4, PB0 == current sensorPA8 for A, PA10 for A',PA0 for B, PB10 for B', PA6 for C, PA7 for C'I need them to work by pair like this : Here is the code that I used to control the phase : #############begin_code###

I want to drive the DJI2312 motor through the profiler and connect it to the STM32 B-G431B-ESC1 inverter.Using MC Workbench to initialize the project (and Motor Pilot) the sensorless case works correctly, but when I use a quadrature encoder (fixed with screws behind the motor) the rotor does not rotate ... you can hear a noise as if it is trying to align but it does not move. There are no faults in the Motor Pilot.I don't have the datasheet of the encoder because I got it a while ago, but I tried changing "Pulses for mechanical revolution" by setting 1, then 2,3 and 4 but it still doesn't work.Should I set something here?

I'm driving a BLDC motor (14 poles) through the profiler and connect it to the STM32 B-G431B-ESC1 inverter. I am using a sensorless control (PLL + Observer) with an auxiliary encoder mounted on top.Motor Pilot allows me to set the mechanical speed at which the motor runs, i.e., 2142 RPM:I plotted (again with Motor Pilot) the speed of the endoer and that calculated by the sensorless PLL. They are about the same, i.e.160:1) However, I don't understand what scale the "y" in the graph is2) Shouldn't the speeds in this second image be 2142 RPM ?? (as set with the Pilot).. maybe I am confusing electrical and mechanical speeds? and/or maybe there is an internal normalization in the code?From this formula: Electrical Freq. (Hz) = 250 Hz      

[VERSION]: 6.3.1[TOOL]: Firmware[DETAILS]:The implementation of MCM_Modulus defined in mc_math.h calls the CORDIC peripheral like this: LL_CORDIC_WriteData(CORDIC, (((uint32_t)beta << 16U) | (uint32_t)alpha)); This works fine as long as alpha is positive. However, when converting a negative alpha from int16_t to uint32_t the upper 16 bits will all be '1', hence beta is overwritten. [PROPOSED SOLUTION]:Mask the upper bits of alpha before combining with beta.LL_CORDIC_WriteData(CORDIC, (((uint32_t)beta << 16U) | ((uint32_t)alpha & 0xFFFF))); Note: Images are attached that show calculated phase current using the wrong and the correct conversions respectively. 

Dear MCSDK users, MCSDK version 6.3.2 is now available: Download It here. This is a bug fix release and here are the main changes for this version: Motor Control Features: FOC Fixed CORDIC Modulus computation in case of negative alpha value  Fixed issue concerning STSPIN32F0 and STSPIN32G0 configurations: polarity of the driver's master enable pin is now correctly set. This issue was integrated in MCSDK 6.3.1 and prior versions are not impacted Fixed HSO temperature averaging when execution rate is greater than 1 Fixed potential FOC duration error with STSPING4 when initialization procedure and MC_APP_BootHook are called after the timer has started Fixed a potential race condition with STM32G0 ADC conversion occurring during very fast START/STOP sequence Introduced boards: Support of EVLSPIN32G0A1/A2/B1/B2 evaluation boards Support of VLSERVO1 inverter board  

The provided example firmware of  STEVAL-ESC001V1 in MCSDK workbench, there is no code in main function while loop. As a beginner, I want to ask; How do we can actually give input and monitor motor performance? Like speed, current etc? Is it possible to provide external throttle signal and then use MCI_ExecSpeedRamp() function?

In motor control workbench 6 there is only HSO (which I don't understand if it's equal to HFI)In motor control workbench 5 there is the option "sensorless + HFI" but it is not settable because it says "not supported in FW for SDK5.x"Is there by any chance a version of motor control workbench that supports HFI + Sensorless ?? Thanks

Ні,I possess the following items:1. Development Board : P-NUCLEO-IHM032. Controller Board : NUCLEO-G431RB3. Inverter Board : X-NUCLEO-IHM16M14. DC power supply 12 V dcI downloaded the STM32 MCSDK 6.3.1 SDK as part of the environment setup, which is included with STM32CubelDE Version 1.16.1 and Motor Pilot_6.3.1 for monitoring purposes. Following the documentation's suggestion, I successfully generated the code for the specified hardware combination. After successfully building the generated code, I was able to flash it onto the controller. Upon powering up the development board, the motor pilot tool displayed the following status. The status is triggered with FAULT_NOW with highlighting the following: Over Voltage, Under Voltage and Driver Protection.Thanks and regards,Prasanth

 hello community, I'm using the IHM17M1 with the NUCLEO-F401RE for a low-power motor control application involving a 6V motor. The setup works well, but under load conditions (such as when the motor is underwater), the speed drops below the reference speed. However, the motor is not drawing its maximum rated current (1A); it's only pulling about 0.2A under load. How can I achieve maximum speed and torque for the motor under these loaded conditions?   @DMeie.2 @MRyan.7 

Hi all,We plan to implement STSPIN32G4 to our custom motor controller solution. For that purpose, we are going to try EVSPIN32G4 board to see if it meet our needs. I have a specific question regarding our implementation. We will use esp32 to communicate with STSPIN32G4 to control the speed of the motor based on the current draw.Our motor is 5 pole 24VDC/18A with hall effect sensor. So, no FOC implementation is planned.What we have in mind is to implement a code to esp32 to set a constant speed via user input and observe the motor current draw for about 1 minute to determine the average current draw during that time and calculate the average current value and set the motor to run at that current value constantly.I played around with a few settings on motor control workbench software and under the Drive Settings Panel there is a option called "Control mode" that can be switched between speed control or torque control. Once torque control is selected, it allows to inpu

I am trying to create a BLDC Controller project based on VESC using the STM32F405RGT6 microcontroller. I have successfully flashed the bootloader and uploaded the firmware using STLink. However, when I connect the IC to my laptop via USB, the IC is detected and can run the firmware only for a few moments (around 2 minutes) before disconnecting. What could be the issue?

Dear,I am trying to profile two different motors using ST Motor Profiler 5.4.8 but it fails on both motors.Setup:Control Board: Nucleo-L476GPower Board: X-Nucleo-IHM08M1 3ShConfiguration:Completed the configuration using this link:Control Board:Removed JP1, plugged JP5 as shown & LD3 turned ON.Plugged in two jumpers on CN2.Soldered bridges SB55 OFF, SB16 & SB50 ON.Power Board:Soldered jumpers J5 & J6 for 3Sh as shown.Removed R181.Plugged JP1 & JP2 as shown.Power Supply:Supplies 12V at max 40A as shown below. Motors:1) BLDC A2212Profile Settings tried so far:No. Poles 14 (Pairs: 7)2) BLDCthere are total of 6 windings. So this makes 3 Pole Pairs? Results:I tried using different max current, poles etc. But, the motor clicks and sometime runs momentarily but profiling always fails. Is there any specific sequence of phases to be used?Please help in completing this profiling step. Thanks

I'm trying out the board designer feature and ran into an issue where after succesfully making a board in Board Designer based on a custom STM32G431 motor controller board, MCWB gives this error about the current sensing not being found:The Board Designer doesn't show any errors: I have a current sensing feature added with 3 shunt resistor readings from a DRV8323 chip: Can anyone give me some advice on what to try next to get this to work?  This is such a cool tool I'd love to get working. 

I'd like to make our application more aggressive so that it can keep its speed constant under different loads.The speed regulator seems to be dialled in pretty good as it follows our setpoint perfectly fine.However, when I load the motor, the current (Torque reference) barely goes up, and I can stall the motor by hand.When checking the high frequency plot, Iq stays well below the configured limits.What can I do to increase the performance in this regard?
