STM32 MCUs Motor control

Dear All,How to purchase a 34-pin cable assembly and radiator (especially heatsink) for the STEVAL IPM30B, what are their specifications, and are there existing products available? 

I am trying to create a project in STM32 Motor control workbench using STM32G030C8T6 microcontroller. I want to use a custom board for this project. I am trying to set all this by creating new power board and controller board and I also tried the inverter board option, but I am not able to generate a program with FOC algorithm for STM32G030C8T6.I am able to create a custom inverter board, but when trying to use the inverter board in a project, then this is the error that I am getting. When I am creating a project using "Modular" hardware mode, and selecting power board and control board that I created, I am getting this error. Why am I getting this issue? and how can I solve this?

We are currently using a DCX32L motor rated at 12V and 160W, and ourmain objective is to achieve constant torque. Specifically,we need a solution that integrates current sensing with an interface that permits real-time control via software. Is this possible any drivers are there ???

Hello,I have two IHM02A1 development boards stacked on top of an STM32F401. My goal is to control 3 stepper motors asynchronously in a daisy chain configuration. Currently I can control the two stepper motors connected to the bottom IHM02A1, but the third motor motion mirrors the first, and cannot be controlled asynchronously. I suspect this is due to the SDI/SDO daisy chain configuration. I believe, since I am using a daisy chain, the same CS pin can be used for both IHM02A1's. Is this correct? Also, according to UM1964, SB10, SB26, SB11 and SB32 are used to configure the SDI/SDO connections. But it is not clear which solder bridges need to be closed/open for stacking two IHM02A1. The default configuration on both stacked boards is SB10-open, SB26-closed, SB11-open, SB32-closed. Can someone direct me as to the proper solder bridge configuration for stacking two IHM02A1's with correct CS and SDI/SDO connections?Thanks,-CodeBlue

Hello,​I am trying to drive a three-phase motor with the STEVAL-IPM15b, but it is not working properly. I applied 15V to Vcc and 125V or 150V to Vdc and tried testing, but the motor did not run. I checked TP5, TP12, TP6, and TP7 with an oscilloscope, and it seems that the gate signals are being generated. I have attached the waveform from the oscilloscope in the diagram.The yellow line shows the signals in the following order: HU (high side U phase), LU (low side U phase), HV, and HW. Additionally, I have set the dead time to 4μs. On the J2 connector, pin 2 is GND, pins 3, 5, 7, 9, 11 and 13 have the respective phase PWM signals, and pin 25 is receiving 5V.If my usage is incorrect, I would appreciate it if you could let me know.​Thank you for your time and assistance.Best regards,Jiro Tyubu.​  I solved it.(2025/3/16) 

HelloIs it possible to connect an external memory IC to the stspin via qspi or spi interface and map the addresses into the addressable space of the cpu?

Hi all,  I have profiled the motor using the motor profiler V5.4.8 where the motor was able to achieve 4500RPM, and then created a position control project CMWB V6.2.1. the motor is using 4096CPT incremental encoders as a primary feedback source. With this project I am only able to achieve maximum speeds of 700RPM and nothing more. Can anyone explain why that would be? I am aware that motor pilot can be used to plot graphs and I have been using that to display the current motor position however I'd like to know if it is possible to plot the target position as well?   /** ****************************************************************************** * @file drive_parameters.h * @author Motor Control SDK Team, ST Microelectronics * @brief This file contains the parameters needed for the Motor Control SDK * in order to configure a motor drive. * ****************************************************************************** * @attention * * <h2><

I have a custom board, which is based on the STEVAL-SPIN3201, it is used to control a low inductance BLDC motor with hall-sensors (100µH). The motor controller is running and is able to control the motor. Unfortunately the phase currents tell that there is something that needs more care. There are two problems. The first is that the phase currents are not as neat and harmonic as I might wish, the second (and main problem) is that once in a while every 10 seconds or so I see this iregularity:The three phase currents:I am uncertain of how I shall debug this, I suspect it has something to do with the current sensing. I would like to dump the raw current measurements from the ADC, but I do not think the chip is fast enough to do so. I have tried to filter the current sensing circuit, but without any luck and without a way of quantifying the noise it is hard to compare. How would you go about debugging this?Informations:Motor: BLDC with Hall sensorsMotor C

Hello,I am reading the documentation of the STEVAL-PTOOL4A, I have noticed that it is equipped with a TRIG_X  to enable/disable the DC/DC booster. I don't know if I understood well its functionality, but It will mainly turn on/off all the board including the MCU. So each time, we trigger, the MCU will execute from the reset_handler right? But maybe I want to keep the MCU on always, and I want to scan an input and when it is On, it will turn on or off the motor depending on its status. How it could be done by TRIG_X? Or I should use in this case another GPIO and I configure it manually? For example could I use the one of the potentiometer instead? Thank you

Hi Sir, I have steval spin3202 evaluation board for an application of bldc motor application. I have generated code using Motor Control Workbench, initally for testing i tested it out using Motor Pilot it was working as expected using Start and stop command using the interface, but i want little modification such that i dont want to control it using motor pilot interface for that, I turn off the UART button in the selection and again flash the code to run the motor but for the running of the motor i need to press the reset button after that i can control the motor usign potentiometer, i also dont want to use user button.Following thing i need to do in the code,1) When i power the board it  should start the motor, i.e i don't want to press the reset button manually for the starting of the motor as for my application i also don't want user button to start the motor.2) In my application if the Source current is greater than 7A it should turn off the motor but in the code i have selec

I have used STEVAL-SPIN3202 evaluation board for Pump application after finalizing the code i have tried to make my custom board from the existing schematic but faced with many issues as listed below1) From the existing schematic i have removed the programmer part and kept the pins open for connecting it through external stlink programmer to upload.2) out the 4 board that was designed and assembled issues like one board was working fine but the debugging through uart pin was not possible, even though i have connected logic analyzer to check if data is transmitted by the mcu or not.3) In some board the PWR LED was not turned on, but as the was assembled same as the working one with same components values.Waiting for STEVAL-SPIN3202 ST team response for detailed explaination of the issue

Hi, i'm using NUCLEO-F401RE product with EVSPIN958 expantion board connected to, for motor control.I've connected this with STSPIN Studio 2.0, it's running correctly with EVSPIN958-SingleMotor firmware (i'm using DC brushed motor).i'm just searching EVSPIN958-SingleMotor firmware code to use it as exemple.I don't have found it on your site. Can you give me link to this information.thanks.

Using Version: 6.3.2I have a custom motor and a custom inverter board, importing these works fine in my project but when I try to generate the project I get the following:2025-03-17 17:54:58,571 ERROR [LineInfo_to_exitCode.manage_IocGenerationError] Unable to generate ioc file due to: Template inclusion failed (for parameter value "STM32F769NI/STM32F769NI - 216 MHz - int.ftl"):...I tried changing the MCU on my inverter to see if this was specific to a board and I keep getting the same bug. Please help :) 

Hi I am trying to configure a custom board to start development for a new motor driver.During this setup I encountered a very weird issue I don't understand. I want to use internal opamps for phase current sensing. These will be single ended opamps with internal PGA. In the board designer software this is shown as using one pin as can be seen in the image below. Yet when I configure this all and generate the IOC using the workbench I see that there are 2 more pins used for "OPAMPx_OUT". Why is that the case and how can I disable it? Please let me know if there is any more information you need. 

Hi,I am learning motor control by using ST Motorcontrol workbench. I'm using P-NUCLEO-IHM002 pack which contains NUCLEO-F302R8, X-NUCLEO-IHM07M1 and power supply.While I trying to use this board, in the user manual they said some changes in the jumper configurations.In the schematics of IHM07M1 power board, I observed that there is no provision for 5V generations. So, I assumed that I gets 5V from controller board, and I also observed that by closing the jumper J9 in the power board causes direct flow of 12V to the control board, so I opened that jumper and given 5V separately to the board and for running the motor alone, I have used 12V only.While running the motor profiler, the motor starts and runs for few seconds and return an error.Help me to resolve this.And I also have a doubt that, In the Youtube tutorial videos they are using only one 12V supply, but how the controller board (NUCLEO-F302R8) withstands 12V? Thanks in advance.

Hello,I am trying to run a BLDC motor using the MC control SDK. The BLDC motor is the following: BLDC 40P30F16P2.063D by MinebeaMitsumi. First, I entered its parameters in MC Workbench + made the profiling for its mechanical parameters, however this step didn't went as expected since I cannot run the motor in full speed, the MC Pilot gives me speed feedback error.Anyway, I was able also to get the electrical angle offset using the oscilloscope (you can find the picture attached) (which is 120 degree). In addition, I tried to run the motor in Voltage and Current open loop as per the manual. I was able to run it without major problem.However, when I want to run it in closed loop using the hall sensors, the motor won't turn smoothly. It starts to do a back and forth movement. I tried to tune the PI of the speed control however nothing is changing. + I monitored the hall effect sensor through oscilloscope when I command the motor to run, there are is no noise affecting the hall effect

i generated the code using the workbench for stm32h755ziq and the motor driver ihm07m1 with a 12v bldc motor...and i have called the api's for motor start as well in the main code ...but after downloading it into nucleo..i cant see any pwm signals on the respective pins of nucleo ...?(assume me i'm completely new to this thing)

Hi, I managed to create a custom inverter board using STMC Board Designer which is basically 1 Nucleo-H755ZI-Q inverter and 2 times a IHM08M1 power board(see Other post about creating bridge ) . One of the 2 power boards is therefore connected to other pins of the Nucleo-H755ZI-Q in order for me to drive 2 motors independently. (included board below)That all worked and I'm able to create a STMC Workbench project (included below) and configure the encoder, stages, etc. All goes well until I want to generate the code, from what I understand is that there are some bindings missing in the foc_assign.ftl templates. There's no support for M2_ADC listed which causes several files to be incomplete (mc_tasks.c and stm32h7xx_mc_it.c as far as I can tell). I've added the files with fault codes aswell.  Could you guys help me create the correct .ftl files in order for me to generate the project for 2 motors for a STM32H755 MCU using the workbench? 

I have 5kW QS138 BLDC motor within my e-bike project with my own motor controller electronics. I have measured inductance and series resistance from the motor with a precision LCR meter: Lq [mH]Rs [ohm]Ld [mH]Rs [ohm] Ld/Lq       120 Hz0.0310.0030.0210.003 0.671 kHz0.0300.1110.0210.067 0.6910 kHz0.0270.2100.0190.148 0.7220 kHz0.0250.5750.0180.390 0.72At MCSDK one inserts the motor parameters and other drive settings. My PWM frequency is 15 kHz with equal FOC update rate. Now should the motor parameters be inserted to the program as measured with this PWM frequency? Or are they assumed to be "static DC values"?By using "15 kHz" values, I get following parameters: Rs = 0.2 ohm, Ld = 0.019 and Ld/Lq = 0.72Going to the "DC end": Rs = 0.003 ohm, Ld = 0.021 and Ld/Lq = 0.67Any suggestion which is the correct end to start iterating? 

Hi there,I am trying to enable the current measurement feature on my BLDC motor setup, but MC Workbench prevents me from enabling it. I think it is due to mode selection - 6step, instead of FOC, but still, current measurement through shunt resistor + ADC should be allows in 6-step mode as well, right?My setup is the following:- Bench 12VDC power supply (5A limited current)- Nucleo-F401RE MCU board- X-NUCLEO-IHM16M1 drive board (including 3/1 shunt resistor for current sense)My version of MC Workbench is 6.3.2My version of STM32CubeIDE is 1.18.0Thank you for your help!

Hello,We are using a custom motor controller board closely based on EVSPIN32G4 dev board for our e-mobility product. It runs a PMSM motor using FOC and HSO for speed sensing. The version of the MCSDK we use is v6.3.2. Basic board parameters are: max current = 45A (mosfets can handle > 100A), and max voltage = 75V.The issue I observe is as follows:When I call MC_StartMotor1(), motor starts and accelerates to its target speed correctly (around 3000 RPM). Then, I start increasing mechanical load on the motor gradually and I see an increase in current draw from power supply. However, when the current draw from power supply reaches about 20A (give or take), the motor experiences a sudden shutdown. When I check motor faults, I see nothing set. Meaning that MCSDK does not see this as a problem. If I call MC_StopMotor1() and then MC_StartMotor1(), the motor restarts correctly again.Another strange thing is that if I set motor target speed to a higher speed
