STM32 MCUs Motor control

The EVSPIN32G4 is not an option when you 'select hardware' in the latest version of the Motor Profiler (5.Y.4). Will it be supported in an upcoming release? Also, is there any plan to support higher RPM profiling? The limit is 16kRPM right now.

used sdk : 5.4.7mcu : stm32f446redual motorIn function R3_2_CurrentReadingCalibration has below code: pHandle->PhaseAOffset >>= 3; pHandle->PhaseBOffset >>= 3; pHandle->PhaseCOffset >>= 3;But NB_CONVERSIONS is defined 16u, So is it true the right code should be  pHandle->PhaseAOffset >>= 4; pHandle->PhaseBOffset >>= 4; pHandle->PhaseCOffset >>= 4;I checked the example code used stm32g431 as below: pHandle->PhaseAOffset /= NB_CONVERSIONS; pHandle->PhaseBOffset /= NB_CONVERSIONS; pHandle->PhaseCOffset /= NB_CONVERSIONS;

Hello, I need help with stspin32g4 I'm programming it with nucleo-64 SWDI wrote a program with blinking led, then trying to start debbugging, i got "Break at address "0x1fff4b14" with no debug information available, or outside of program code."despite this downloading goes on,but led doesn't blinking, it starts when i turn off and turn on power supply of stspin32g4, so it looks like it is on breakpoint 

I succeeded in attaching steval-esc002v1 to the px4 system.However, there is a problem that the motor is not smoothly controlled through the controller. If you look at the video, it looks like it's moving by step. Can you tell me what parameters I need to see?https://youtu.be/d4GWsD45kWAAt px4, the control pwm output is 400hz, and it has 36% IDLE duty and 43% ARMING duty. So STEVAL-ESC002V1.h is changed as follows#define BSP_BOARD_IF_TIMx_MIN2MAX_BITS (11)#define BSP_BOARD_IF_TIMx_MIN_SPEED_TON_US (1070)In addition, since it is a no-load motor for quadcopter, MC_SixStep_param_7PP_3S_propeller.h was changed as follows#define TARGET_SPEED 50000Other parameters are the default provided in STSW-ESC002V1.

Hello everybodyI'm using ST Motor Control 5.4.1 to drive a BLDC motor. It works fine, and I'm able to drive in SPEED MODE my motor, changing speed and with the system that can react to load changes.I would like to realize a software limit, so I can limit current to a certain max value during RUN, and after some time remove the limit and return to normal operation.I've tried to change SpeednTorqCtrl_Handle_t parameterms but it doesn't work.I've tried to change current Iq reference via API but the same as before: the behaviour is not as I would like to obtain.I think it can be simple to do but I'm not able to set maximum current for short period of time.Does anybody know how to set this values?ThanksRoberto

Finally was possible run the motor on my CNC machine and do a position control, I want to share the graph that I received from Current_Position register.There is some overshoot in my position control and I would like to tune it as much as possible.So, What would help me to have a nice plot?Playing with Position Ki,Kd? Working more with Iq and Id? add more cap into my driver system? I also try to config the max current limit on Workbench but seem there is no parameter to adjust that! My motor normal Current is 5.2A at pick of 15A but workbench set into 30A limit.I used IMH08 with 431 controller board 3sh sensor.

I use 16KHz PWM to run motor, once the motor over 24000RPM, the motor current will become very high and unstable. it is seems over than FOC execute rate cause this problem.I'm not sure I think is right or not ?   is there any suggestion please tell me.when I use G431B MCU with 30KHz PWM to run same motor, it looks run very well with no problem (can over 40000RPM) P.S 1. motor parameters: Vm: 12v / Rs: 0.3 ohm / Ls: 20uH      

For calculating apriori PID parameters when running ST FOC SDK, you obviously need to consider the sampling time of the regulator for the integral term. According to UM1052, current sensing is synchronous to the PWM. Is the sampling period of the current sensing ADC the same as the sampling period of the current PI controllers ?Again, referencing UM1052, page 38/178, formula for Ki; is T equal to 1 / pwm_freq ?@cedric H

I am currently trying to compile an image for a qualcomm ESC board (STM32F0xx based brushless DC controller). I manage to build the firmware up to the last step, where the firmware is encrypted using a key. To do this, the make file calls a utility, stm32-encoder. I can't find this utility anywhere, online or in the stm32 toolchain. Can anyone point me in the right direction?

I have the F767ZI board. It would take a long time to create something from scratch. I've tried searching, but most outside C++ programs draw from a bunch of external libraries.(Additionally, I'm using the IHM02A1 dual motor driver.)

Hello,We cannot move a BLDC motor (using the x-cube-spn8 demo software with IAR) with STM32F302 and IHM08M1 driver.It attempts to move but is stuck and bound up. Once in a while immediately on starting app it would move a few revolutions before binding up. The demo ramps the velocity in cycles, which I can hear when it is driving. Both the motor driver and HALL pins are connected to the IHM08M1 driver board.We are using the latest version of the IAR compiler v 8.32 and this is where I downloaded the demo software:https://my.st.com/content/my_st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-spn8.license=1545308016142.product=X-CUBE-SPN8.version=1.0.1.htmlWhen I opened the project file it converted the x-cube-spn8 project to be able to be used with the latest compiler. Is this OK or do you recommend a specific compiler version?Are there any parameters that we should know that can cause the motor commutations to not fi

I have designed a custom board based on STSPIN32G4 schematic but with an automotive mosfet (iaua200n04s5n010auma1).Everything works except that the controller enters an overcurrent fault every time i start the motor pilot GUIDoes this have to do with the internal Mosfet gate driver?Thanks, and best regards,Aminu

Hello all,I have a 20 pole pair, 100v, 120Amp, 15mOhm. 34uH,  sensorless, BLDC outrunner motor.I have had this running on the B-G431B-ESC1 dev board with 25v at 800 RPM drawing 1.5 Amps. The power supply being lab bench supply capably of 30vDC and 5Amps.I have followed the same basic circuit layout and created a custom PCB. The main differences being a 0.2mOhm shunt, and associated voltage divider/bias resistor values and opamp gain. The buss voltage sensing I have left at 25v for now. And the MOSFET output stage is made with higher power devices, eventually with 5 sets in parallel. I am also using a STM32G431CBT6  LQFP48 for simpler prototyping. A few small differences in the pin-out are not a problem, and as far as I can see it should be compatible.The firstly, is the STM32G431CBT6 truly compatible in this application, or have I missed something? For the rest of the changes I have Cloned a copy of the B-G431B-ESC1 .json file, and modified the sections for cur

I'm using ST Motor Pilot V1.1.5 with eval board B-G431B-ESC1.Motor: IBL-100SW-1 http://www.itomotor.com/product/detail/67.htmlMotor Profiler Configuration:Pole Pairs: 3Max Speed: 2000 RPMMax peak current: 5 AMagnetic: I-PMSMld/Lq: 1After starting the profiler, the motor tries to start. But then, after a few seconds the profiler stops and shows the fault message "Over Voltage". This happens even if supply voltage is only 12 V. The oscilloscope shows that PWM peak voltage starts with 12 V and then rises up until more than 30 V between GND and motor phases.

I was able to run the ST MC Workbench toolfor motor and parameter configuration successfully and the motor ran fine. I then uploaded the generated code through STM32CubeIDE however once uploaded when I try to start the motor there is an audible click from the ESC and MC workbench an over current fault is shown. The motor ran fine in the motor profiler and did not show a fault. In the MC workbench overcurrent is turned off in the power stage. In the control stage I increased the current threshold and it was unsuccessful also.If you need any other info please say thanks

I am trying to work with the STEVAL Ptool2v1 BLDC controller, but have had no success in getting it to work. I have downloaded the STSW-PTOOL2V1 software and unbundled it to a hierarchal dir system, which leads to a project dir, where there is a project  File "EVALSTSPIN32F0H25-HallSensors". I dont understand this sudden change of hardware especially since the circuit diagram of the PTOOL2V1 is very different from the ST MX diagram of the yP of the project directory. This doesnt seem right, this PTOOL board is so badly documented. 

Dear STMicroelectrinics,I encountered with some problem with product p-nucleo-ihm002. The problem is about speed and torque control but not with position control.The hardware is the following:- p-nucleo-ihm002 (nucleo-f302r8, X-Nucleo_IHM07M1 , bull running br2804)- ISC3806-003G-1000BZ3-5-24F encoder with 1000 ppr (A,B,Z signals)Software:- MC_SDK_5.Y.4- Firmware Package Version STM32 FW V1.11.3- STM32CubeMX 6.5.0- STM32CubeIDE What works:When p-nucleo-ihm002 is used in sensorless mode with FOC 3-sh control in speed control, the motor behaves as expected: it follows the referenced speed commands (for speeds higher than some lower bound).What partially works:When p-nucleo-ihm002 is used in sensored mode (with Encoder) with FOC 3-sh control in position control, the motor follows the given reference command for angle positioning, but in some cases it speeds up to high rpm for no reasons.What doesn't work:1. When in sensored&n

I'm trying to get the basic firmware running, but I think I'm doing something wrong because the ESC doesn't seem to function. I've generated an IDE project for the B-G431B-ESC1 using the ST Motor Control Workbench, which I then opened in STM32CubeIDE and clicked "Build 'debug' for project" followed by "Run". Everything seems to complete without issues, but when I power the ESC with a 24V supply and give it a PWM signal from a XP3-SSi RC controller the motor doesn't run.I attached the project's log file, as well as the output from the build and run commands.

I don't know where to report it. In the file MotorControl/MCSDK/MCLib/Any/Inc/hall_speed_pos_fdbk.hIn Line 232 is missing:...#ifdef __cplusplus}#endif /* __cpluplus */....#endif /*__HALL_SPEEDNPOSFDBK_H*/

Hi all,       I'm Siva, and i need a BLDC motor driver to run a 5kW motor. please suggest me in buying out the right driver board. the voltage needed for the motor is 48 volt and the current needed will be 180A.   

I'm trying to make run a motor via Motor Pilot but it does not work correctly. I'm using the following motor: 1 stücke Mitoot 5008 335KV/400KV Bürstenlosen Motor Für 1555 1755 Propeller Quad kit RC Multicopter Hexacopter Tarot T960 t810|Teile & Zubehör| - AliExpress. That unfortunately does not have specifications to work with.Board used:NUCLEO-F446REX-NUCLEO-IHM16M1 3ShHere are the values I have set for the motor:Pole pairs: 7Maximum speed: 10000 RPMMaximum current: 0.4However, I'm uncertain whether these values are correct, and I suspect they might not be. When I start the profiler, it gets stuck at 14%, and I I get the following window:I'm wondering if anyone has prior experience working with this particular motor. Could you provide guidance on how to determine the correct values for the motor settings in order to make it run properly?
