STM32 MCUs Motor control

Hi,i'm using the a STEVAL-IHM034V2 board for evaluation (PFC + FOC PMSM).i am using three phase induction motorwell I am using the Motor Control Workbench 5.4.7, for generating code , Keil uVision5 for burring the code in Controller ,  the code is burned through STLink, its burned but the motor is not started, even not getting the voltage at the output,PWM is not working , and Inverter part also not working motor workbench is connect through serial communication , and opened the monitor window and connected, but still not workingneed your support and help to operate this board Thanks a lot in advance Thanks and Regards Mudassar

I'm trying to use this board to develop the serial I/O "user interface" for my application but I don't have my custom board yet.

I have Nucleo-F302R8T6 and STEVAL-IPM15B. But I don't know how to connect the pins. I tried to connect it by looking at the pins from the Motor control workbench program, but some pins were exposed, RX, TX pins were exposed. Can you help me how to connect Steval-IPM15B?

The generated codes are same when check or not check the button 'Encoder Alignment'.

Hi all,​I am using f303rb with ihm08-1sh to control a motor, motor control is MCSDK 5.3.2Using HSI which has 64MHz clock speed.I set the PWM frequency to 15K, and FOC execution rate = 2.In most time, it works okay.In a very low probability, it will OC when motor starts, and controller (MOS/driver IC) damaged.Look at the waveform, the PWM duty looks very weired. It's not the same as normal situation.The PWM duty looks full for couple of cycles and motor will rotate wildly.I don't know if it's related to 1-shunt or any other else.Does anyone have similar problems?PS.We can reproduce the problem with a run-4sec/stop-1sec without loading test in an hour.Thanks,Jungchu

Hello everyone!I'm developing an application with a little Fanuc Beta Series motor with a custom encoder. I was using a NUCLEO-F446RE, but it burns some tests ago :( Now I'm using a Chinese board with an F103C8T6, but not working properly.I attached a video and upload the same video on YouTube if you prefer. The first part of the video shows the problem. I start the motor on the software and the motor locks at the initial position. I already tried a lot of things, including invert the encoder direction.Despite that we can see the current control working properly.The second part of the video shows a test with the encoder detached of the motor and rotating the encoder with my hand. In my mind, this test shows that there is no problem with drive circuit, no problem with encoder and no problem with the motor, because the movement is smooth, with no jump of phases or something like that.The third part of the video shows the same test with the encoder inverted.Can someone help me?Link o

Hi,I am trying to control a SPMSM using EVSPIN32G4.I can't find any example for X-CUBE-MCSDK with EVSPIN32G4.So, please link for the examples or materials for studying.Thank you.

In the powerSTEP01 datasheet, it is mentioned that VSREG must be always less than VBOOT (and VCCREG must be always less than VCC) in order to avoid related ESD protection diode turn on. The device can be protected from this event by adding an external low drop diode between the VSREG and VS pins (VCCREG and VCC pins).However, further explanations on the ESD protection diode is not found in the datasheet, and the diode is also not in the block diagram. So my questions are:Where is the location of ESD protection diode? What are the consequences if ESD protection diode is turned on? And is it a must to add an external low drop diode between the VSREG and VS pins?

I have SVSPIN32F0251S1 board and a BLDC motor without sensors that i am trying to get to spin but the example for this board inculded in the motor control workbench does not work(and gives a lots of error even before it can be compiled). And if i try to make a custom project based on the board in the motor control workbench i can connect to the motor pilot software and get some data and get the motor to click but the software always gives errors and it seems to be something wrong with the current reading(if protection is enabled it gives over current fault and if not the power meter shows 65000W). Has anyone got this board to work with the example software?

Hey there, I'm trying to generate code with the Motor Control Workbench V5.Y.3 for the Nucelo H745ZI. I selected the sample project in "Projects\NUCLEO-H745ZI\..." saved it somewhere else and tried to generate code. In the project generation dialogue all three buttons (Update, Run STM32CubeMX, Generate) are greyed out. (I'm still on CubeMX V6.3.0)Does anyone know how to fix this? Or how to use an H7 processor outside of this example project? The log file just shows this: 2021-12-11 00:15:35,379 DEBUG [Main.lambda$run$0] Arguments: [-ioc, C:\Users\Soeren\STM32CubeIDE\workspace_1.5.1\testmot123\NUCLEO-H745ZI_IHM07_3S\NUCLEO-H745ZI_IHM07_3S.ioc, -xdm, C:\Users\Soeren\STM32CubeIDE\workspace_1.5.1\testmot123\NUCLEO-H745ZI_IHM07_3S\NUCLEO-H745ZI_IHM07_3S.wb_def] 2021-12-11 00:15:35,386 DEBUG [ArgsValue.readPropertiesFile] [AppConfig] pack.source = "C:\Program Files (x86)\STMicroelectronics\MC_SDK_5.Y.3\Middlewares\ST\MotorControl" 2021-12-11 00:15:35,386 DEBUG [ArgsValue.readPropertiesFile]

I use custom board on STM32G474CEU6 for position control. I use topology with 1 shunt resistor and spi-encoder AS5048 with custom driver. At the start motor soft work fine, but after command set position more than 2.1 radian motor stay at position 2.0 radian and current consumption increases to 0.8 amp (is nominal current) and rotor stay in this position after any command.

Hello,I'm using F429 to control BLDC motor with 6step_lib on my drive board.But compared to the other ESC board sold on market, my drive has higher current:​I write TIM1 registers such as CCRx and CCER when HALL sensor edges triggering. And uncomplementary PWM for 6step.c.My peak-peak current are about 1 Ampere bigger than other ESC drive board when dragging the same bldc motor at full speed. I attached captures of one phase current, its hall sensor and terminal Voltage of my board and the other ESC board separately. I don't know where consume this 1A current.I suppose that the other drive board may apply some "field weaken" technique because I found the terminal voltage has jump at turning point showed in second capture, however, I'm also confused that THIS voltage does not advance hall sensor . My board has no voltage jump at turning point showed in first capture.​​regards,​my drive board: the other ESC board:​​​

Hello, I'm just getting started with STM32 and got my hand on STEVAL-SPIN3202. I did follow the manual and install X-CUBE-MCSDK, stsw-link009 driver and everything the manual suggested. However, I couldn't get the workbench to regcognize the board and keep getting the error "Connection fail! no response, check the communication cable, the power on the board or the baudrate". I did look around in this forum and realized this is a common occurance. However, even though I making sure setting the workbench baudrate, Digital I/O parameter and Device manager comport baudrate to 9600, the problem still persist. I did re-generate the code everytime I change the parameters so I don't know the cause of the problem anymore.Best Regard.

STM Motor WorkbenchWhen I tested the motor in Motor Profiler, I am adding the settings to MotorControl Workbench, and generated the project in CubeMx, but when I try to compile the program I have 20+ errors like:undefined reference to `STO_PLL_Init'undefined reference to `RUC_Init'in question (https://community.st.com/s/question/0D50X00009XkWF5/motor-control-sdk-510-and-sw4stm32-not-compiling) was the same problem, but the solution didn't work, I think I didn't know how to add a library in STMCUBE_IDE right, maybe it's a problem.Board: Nucleo-F303RE + IHM16M13SSoft: STMCUBE_IDE 1.8.0Motor Workcbench 5.4.8

Hello everyone! It's a pleasure to participate of this forum.I developing a custom hardware with two ICS (Isolated Current Sensor) and i have a question. With this configuration MCSDK receive a sin wave signal, right? Just to clean up the doubt.Thanks.

I tried Motor Profiler by selecting Nucleo-L452RE and X-NUCLEO-IHM08M1. However, the actual MCU board is Nucleo-L452RE-P. The profiler first updated the firmware in L452RE but when it comes to verifying the firmware, it throws the attached error.

I have designed an FOC driving board using the chip STM32F302K6U6,but I can't find the the chip in the latest version of MCSDK.How can I create an FOC project by the chip?

When i changed 22ohm with 100ohm my motor run

I use Schematic diagram of "EVSPIN32F0251S1" in my design with Hall Sensor and I use all its configuration for my board :and I used a below BLDC motor :power:300Wcurrent:10.5Avoltage :36Vspeed:3000 RPM but I do not have any move in my motor and output phase U and V is:I have no Ls and Rs and B_emf about my motor

I check to run motor with sensor-less FOC, and I referred to UM2374.​​I have the boards "Nucleo-F401RE" and "X-Nucleo-IHM08M1 3Sh".​so I need to control the constant torque even in case of motor stop.and I would use the absolute encoder type, it outputs ADC output.​How do I implement?

I have genereted project for inverter EVSPIN32G4 in MC SDK 5.Y.3 (FV 1.4, MX 6.3.0) - project is attached to this thread.I have added in project :int16_t g_goal_torque; int16_t g_current_torque; uint16_t g_mc_current_faults_motor; uint16_t g_mc_occured_faults_motor; State_t g_stm_state_motor;and in loop:g_current_torque = MC_GetPhaseCurrentAmplitudeMotor1(); g_stm_state_motor = MC_GetSTMStateMotor1(); g_mc_current_faults_motor = MC_GetCurrentFaultsMotor1(); g_mc_occured_faults_motor = MC_GetOccurredFaultsMotor1(); MC_ProgramTorqueRampMotor1(g_goal_torque, 0); MC_StartMotor1();When I run the application I have readings of current not near 0, but near 2700 (in pictures).I have second issue (it is very possible, that this issue is connected with first one). When I set torque (variable g_goal_torque) something about 2000, joint sometimes starting with oposite direction or start to sheaking. Could You help me with find solution to fix those issues?

I am using an STM32G431 running the ST motor control library for FOC sensorless control. My motor is running but the start-up performance is not satisfactory. I have about a 10% start failure. I have watched the YouTube video: Motor Control Part5 - 7 FOC with STM32 (STO, PLL, Cordic, MTPA, FW, FF) and they show a plot of Observer Elec Angle and Observer BEMF as shown here: Note the bemf amplitude is very clean and uniform, no modulation.For my motor I think the low inertia could be a problem. The start current is about 500mA but the run current is only about 35mA. My similar profile of Observer Elec Angle and BEMF is shown here:Note the ramp-up BEMF is modulated quite a bit. I think this leads to the high failure rate. I get MC_START_UP failures. I've tried tuning everything I can think of but can't find a good solution yet.Can anyone give me some guidance on this?Thanks,Brian
