STM32 MCUs Motor control

1.I want to control a BLDC motor. Why can't I choose BLDC type in MC workbench? There are two PMSMs motor types available to pick.2.Does anyone know if the set (X-NUCLEO-IHM07M1 and NUCLEO-L476RG) would be enough to control this motor?(https://uav-en.tmotor.com/html/2018/GB_0402/34.html) We want to use quadrature encoder and torque control by FOC method. Any help would be great

Hi I updated to cube mx 6.3 and now code generation in ST Motor Control Workbench (5.4.6 and 5.Y.0) does not workerror wrong java jre 11

Hi i have been using stspin32f0602 controller​ for a while now I want to switch a motor which has motor voltage of 450 v and my supply voltage is around 650 v dc can I use this controller please help me out

HelloI'm using a NUCLEO-STM32F446RE and a X-NUCLEO-IHM08M1. And the used Motor Profiler version is ver 1.3.2 (MC SDK 5.4.5).I changed the IHM08M1 according to UM1996 page 6 (Removed Capacitors C3, C5 and C7, Set Jumpers JP1 and JP2 closed and J5 &J6 on 3-Sh side).Additionally are on the IHM08M1 J9 open and JP3 closed.The motor is attached to IHM08M1 with U on Out1, V on Out2 and W cable on Out3.The NUCLEO-STM32F446RE Jumpers are configured as mentioned in UM1996 to JP1 open, JP6 closed and JP5 on E5V side.The settings in the Motor Profiler are as in the Datasheet of the motor on    3 Pole Pairs,    4500 RPM Max Speed (motor's datasheet has this value as speed - no load)   16 Apk max Current (that's the Peak Current in the motor's datasheet)   48 V VBUS (the rated Voltage of the motor)   SM-PMSM Magnetic (assumed, as no Ld/Lq-ration is mentioned in the datasheet)Running the Motor Profiler with this configurat

Hi All,I am using Nucleo-F302R8 with IHM08M1 power board, 3 shunt mode with hall sensor and FOC SDK V4.3 algorithm. I am able to run my 1KW BLDC motor in Speed control mode. I set the target speed is 3000 RPM. Motor starts and goes upto 3500 RPM and trying to slow down speed, during this time Overvoltage fault stop the motor. My ultimate aim is to drive motor at 6000 RPM in 30 seconds. Kindly guide me to tune the parameters.

I have a design which uses STM32G431C6T6 (LQFP48). In the MCSDK, it is possible to select only between STM32G431RB (LQFP64) or STM32G431CB (UFQFPN48).Is it somehow possible to configure/hack the MCSDK use some different MCU? This LQFP48 version of the STM32G431 is very close to the UFQFPN model anyway..

Sorry this is my first time to use MCSDK, I am not sure what can I do.I follow Motor Profiler to set my board, and I check my pin map with my motor.When I want to contorl my motor with MCSDK, it always warning over current.I am not sure I have to set or edit what.My motor Max current 10 Apk. ​And I have another question, I can connect MCSDK ,but I try connect Motor Profiler warning.It say control board communication is still missing. Do it effect my control speed accuracy?​I use MotorControl Workbench 5.4.5 to control my BLDC.Control board: NUCLEO-F746ZGMotor drive: X-NUCLEO-IHM08M1Compilation tools: IAR EW for Arm 8.40.1My motor:In the MCSDK I set value:Hope you can help,regards

Hi,I have STEVAL-IPMNG8Q-3h and I want to drive PMSM motor.In the code generated by the ST WORKBENCH, I get this error!!"Description Resource Path Location Typeunknown type name 'RTC_HandleTypeDef'; did you mean 'I2C_HandleTypeDef'? stm32f3xx_hal_timebase_rtc_alarm_template.c /28.07/Drivers/STM32F3xx_HAL_Driver/Src line 98 C/C++ Problem"How can I solve?

Hi everyone!I try use SDK with sensor AS5600(12-Bit Programmable ContactlessPotentiometer) and 1/2-H Bridge Driver DRV8313Motor is 24N28PMCU: STM32F072C8T6One shunt resistor with LM2904I choose hall sensors in Workbench:Sensors displacenent: 120Placement electrical angle: 0Input capture filter duration: 5.33usec and I convert values AS5600 in HALL-values: 5,1,3,2,6,4 depends on angle. In my case every change of angle 4.25 degree - change hallstate in struct HALL_Handle_tI do it in while() and if hallstate is changed I call void * HALL_TIMx_CC_IRQHandler( void * pHandleVoid ). Here and in static void HALL_Init_Electrical_Angle( HALL_Handle_t * pHandle ) I comment next code ih these functions:  /* pHandle->HallState =(uint8_t) ((LL_GPIO_IsInputPinSet( pHandle->H3Port, pHandle->H3Pin ) << 2) | (LL_GPIO_IsInputPinSet( pHandle->H2Port, pHandle->H2Pin ) << 1) | LL_GPIO_IsInputPinSet( pHandle->H1Port, pHandle->H1Pin ) ); */and instead of bPrevHallStat

Hi, I am studying for ultra-high speed PMSM (about 100krpm, 700~1000W).​The motor is 2pole/3slots/3-phases sensorless motor.I think STSPIN32G4 is a suitable driver for my motor in the electrical specification.​Just I want to check that I can freely control the motor using the driver with X-CUBE-MCSDK (I mean torque and speed controls).Thank you.

Dear Community,using the ST Motor Control Workbench 5.Y.1 I got an BLDC motor up and running pretty easily with the "Singel drive and CCMRAM with NUCLEO-G431RB [..]" (CCMRAM) example.I also wanted to try the Six-Step Hall Sensor and Voltage Mode on a NUCLEO-G431RB (6S_IHM16_HS_VM) example in order to test the 6-step control algorithm.But as far as I understand the code, there is no difference regarding the current control algorithm.The code of both projects was generated by the ST Motor Control Workbench, which actually doesnt support to select the 6-step control option explicitly.Is it even possible to get an example of the 6-step control via the MC Workbench?If not, are there any example projects for the STM32G431?Thank you so much!

In my sensorless application driving a BLDC I need the best resolution possible. I set the SPEED_UNIT to _001Hz but the feedback from the SPD_GetAvrgMecSpeedUnit procedure still seems to be in units rounded to 6. For example I can read 3059 and 3064 but nothing in between. I'm running a 6 pole-pair motor at nominally 30.5Hz and my requirement for speed variation is <2us p-p jitter. I'm finding it quite challenging ;)I'm using a STM32G431 48-pin device with a STSPIN233 using 5V on a custom board. My start current peak is about 700mA and my run current is typically 35mA peak.For my speed feedback in procedure STC_CalcTorqueReference is SPD_GetAvrgMecSpeedUnit the correct procedure to use to get measured speed?Also, I can not find the source code that SPD_GetAvrgMecSpeedUnit uses to calculate the average, I think it is procedure STO_PLL_CalcAvrgMecSpeedUnit. Is that available?Thank you for consideration of my problem. All suggestions welcomed.

In the FOC motor code the average mechanical motor speed is returned by procedure SPD_GetAvrgMecSpeedUnit which simply returns a value pointed at. I'd like to know the details of how the average is done and over what period of time and what sample rate. I believe it may be using a define STO_FIFO_DEPTH_UNIT from drive_parameters.h but am not sure of this.Any documentation or discussion of this would be helpful to my project.Thanks,Brian

Hi all,​I am using MC Workbench to generate motor projects.​As I upgrade my STM32CubeMX to 6.3.0, it doesn't work anymore.​I can directly use STM32CubeMX, but cannot generate source via MCWorkbench.​I tried MC Workbench 5.4.4, 5.4.6, 5.Y.1, and all of them failed to generate.​​I noticed that when using CubeMX 6.3.0, it will popup an error screen showed I need java version > 11.0.10.​When using Workbench 5.4.4, if I installed a higher jdk/jre version than 1.8, it will guide me to install java 1.8. If I installed jdk/jre 1.8, it will pop up it needs 11.0.10.When using workbench 5.4.6 or 5.Y.1, since it bundled jre, it will always pop up it needs 11.0.10. I checked the bundle java version, it's 1.8 .................Currently, I can just use CubeMX 6.2.1 + MCWorkbench to generate source tree.Please help to fix this issue or guide me how to use this.Thanks,Jungchu​

I customized a version of the EVSPIN32G4 eval board to spin my 2 pole pair BLDC 24V 2A motor in sensorless FOC mode. My schematic is similar to the eval schematic. When the motor is spinning the STSPIN32G4 on my board is getting to 65 degrees C which isn't terribly hot, but I do wonder what my options are for reducing the consumption. I'm more interested in reducing the consumption than reducing the temperature. I see there are options for VCC for the buck converter, maybe running at a lower voltage could help? Are there other ways to control the power consumed?

helloI have been purchased one of STEVAL-PTOOL1V1 evaluation board.I am going to develop sample code which provided by company, but some errors occurred in building new file process by IAR & Keil IDE.errors of following:no definition for "MC_Core_Start"......no definition for "MC_Core_Stop"......no definition for "MC_Core_Brake".....it seems the sample code which provided by your company is not complete & same functions are just declared & no defined.it would be appreciated if you provided a revision to mentioned sample code.thanks & best regards.

My computer crashed & I needed to reinstall all my tools on another system. Both are Windows 10 64x. I can't get the Motor Profiler 5.4.3 to connect on the new system. When I try to connect I get a message it can't find the MFC100.dll. I installed the Visual C++ 2010 redistributable and got the same results after rebooting. I uninstalled the 2010 redistributable and repeated with the 2013 version. Same results. The system connects fine with the Motor Control Workbench 5.4.3.What's the secret sauce ??

I am designing a motor controller PCB that uses an STM32G4 MCU (since the CORDIC accelerator and FPU will be useful in my application). One of the required features for this project is cycle-by-cycle current limiting for a BLDC motor. I have two phase current sensors for phases A and B which I am reading through inputs that have an ADC and comparator. In the documentation I read how the comparators can be used to implement cycle-by-cycle current limiting. However, I need to be able to apply current limiting to positive and negative currents (i.e. the current magnitudes) of each phase. It looks like comparator window mode is meant to solve this exact problem. However, it appears that the STM32G4 series comparators do not have window mode. Is there a recommended alternative to window mode that would allow me to cycle-by-cycle current limit on both positive and negative current peaks?

I try to drive (FOC) BLDC motor with STM32G474RE MCU. I use a custom board. I use INA240A1 for inline current sense. Can I use 3 shunt inline current sense method for ST mcsdk ? In STs evaluation boards typically low side shunt resistors are used for current sensing. But I use inline current sense method. What changes should I do in software?

Have Nucleo-64 STM32L476RG and STEVAL-IPM15B , i plan to test VFD and FOC drive for pump with ACIM motors , but the workbench motor control is for pemanent magnetic motor !!are there any additional library or sdk to handle ACIM motor ?

STEVAL-PTOOL1V1 , is it support 500 rpm to 12000rpm in three wire BLDC Mode. My motor operate 12v or 24V. i Want to Run this BLDC Motor from 500 rpm to 12000rpm at a PWM or Analog Speed Control.i want to also Direction change and Break. this Board has the features?
