STM32 MCUs Motor control

Hello all,I'm trying to learn how to control multiple servo motors with STM32.I need to run my servos at 333Hz - and I don't know how to change the frequency from the default frequency?Could anyone help me please - any example code / guide will be much apricated.Gal 

I am running a 28 pole 20A nominal motor using x-Nucleo IHM08M1 and a nucleo -G431RB. I have been doing a number of tests verifying locked rotor current/torque and checking the effect of different settings of proportional gain. I am using Stm32CubeMonitor to monitor all the variables.I am using 6 step control. and Hall devices for sensingMy understanding seems to be progressing. answers to the following two questions would assist me greatly.1/        When I use the following code to monitor the speed  MC_ProgramSpeedRampMotor1(1,0);MC_StartMotor1();for (int i = 1; i <= 200; i++){Faults =MC_GetOccurredFaultsMotor1();speed = MC_GetAverageMecSpeedMotor1_F();HAL_Delay(50);}MC_StopMotor1();I get integer values for speed and in multiples of 6. eg the speed value jumps from 0 to 6 to 12 etc whereas I am expecting a float as an answer. The final speed is 36 rpm whereas I expect it to be 6 rpm.What am I doing wrong? 2/      At 28 po

Hi everyone,I try to get my motor control setup working:Hardware: Nucleo  L476RG with ihm16m1 expansion board, motor Gart ML5008 330KV, 24V power supplyI am trying to get my BLDC motor to spin by using motor control FOC library.I generated example project with Motor control workbench and managed to run it but the motor does not spin.My questions:Is this hardware even compatible? Are there any good tutorials or example projects to begin with?Thanks in advance.

Hi, st team,mcsdk: 6.2.1control board: nucleo-g474reBridge: XNUCLEO-IHM09M2Power Board: STEVAL-CTM009V1We're going to buy around 10k-25k uc per year.1. STEVAL-CTM008V1 schematic diagram defines that it is possible to use 3 ICS. 2. X-NUCLEO-IHM09M2 circuit schematic Fig.1 defines that PhC current can be obtained via MC19(PC0) I've assembled STEVAL-CTM008V1 with 3-rd magnetic current sensor.Could you please advise how can it be achieved?1. Can I configure 3-ICS reading via workbench?2. If I clone STEVAL board, is it possible to configure the current sensing to read the 3-rd sensor? 3. Should I modify firmware sources, generated by workbench? Appreciate in advance,Taras.

Hi, ST community.I'm trying to drive a motor using Nucleo-H503RB. At that time, I am trying to change the USART pin of STLINK and connect it to Motor pilot, but it does not connect.＜Detail＞I want to use PB14 and PB15 for the STLINK USART pins instead of the default PA3 and PA4 (because I use PA4 as DAC).I changed the Nucleo-H503RB json file for Motor Workbench and solder bridge (SB2&SB3→SB18&SB22, SB19&SB33→SB20&23) to change the USART pin. In Motor Workbench, the USART pin has been changed from USART3 to USART1. However, it does not connect to Motor pilot.（Defalut setting (PA3 and PA4) were worked correctly. ）The software I use to generate F/W is Motor Workbench 6.2.1,  EWARM V8(but debug in V9), CubeMX6.10.0, STM32Cube_FW_H5_V1.1.1.I will send you the Workbench file, json file I was change, and EWARM F/W file that I used.  

Hi everyone, I want to simply use the B-G431GB-ESC1 evaluation board for making a model of my 3-phase brushless DC motor:https://dk.rs-online.com/web/p/dc-motorer-jaevnstromsmotorer/2163791?gb=sAs for now I just want to flash the evaluation board with "Motor Profiling" firmware as described in the Motor Profiler documentation. I have followed all the steps in this startup-guide:https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:STM32_MC_Motor_Profiler_-_Start-up_guideI'm using MotorControl Workbench 6.2.1 and am opening the Motor Profiler from there.However, whether I'm using MotorProfiler or MotorPilot, I get the "over current" error, but no current except for the quiscent current is drawn from my PSU:By reading the chapter "Firmware errors" here, I have no idea if this is applicable for me. All the parameters in the MotorControl Workbench are made from the choice of inverter board, so I can't see how this can go wrong? Also, in the startup guide it is described that one can pic

I have the X-Nucleo-IHM07M1 siting on top of NUCLEO-F302R8 as shown attached. Trying to connect as follow? It is possible to connect 24V onto this board to drive 24V 3 phase motor?  

I am doing the project to control linear motor, For that I am using UART to send start and stop command to start and stop motor, as like this i sending different rpm value from 100 to 3000 randomly to change the ramp of the motor. The problem that i am facing is for 3 digit number RPM i am getting output, but when is comes to 4 digit value i am not getting proper putput, For example: For 1000 RPM, I am getting 100 RPM as out put Baud Rate: 115200 bps Data Bits: 8 Parity: None Stop Bits: 1   void HAL_UART_RxCpltCallback(UART_HandleTypeDef* huart) { int cmd_ok = 0; rxbuffer[strlen(rxbuffer)] = '\0'; if (strncmp((const char*)rxbuffer, "start", 6) == 0) { rxbuffer[strlen(rxbuffer)] = '\0'; flag = 1; cmd_ok = 1; // MC_StartMotor1(); } else if (strncmp((const char*)rxbuffer, "stop", 5) == 0) { rxbuffer[strlen(rxbuffer)] = '\0'; flag = 0; cmd_ok = 1; // MC_StopMotor1(); } else { rxbuffer[strlen(rxbuffer)] = '\0'; char* endptr; uint16_t rpmValue = strtol((cha

1.Using the STSPIN4G chip, after enabling the timer output, an error message will be reported stating a short circuit and the motor will not run.2.The upper arm of the entire bridge MOS is conductive, while the lower cliff is disconnected. Want to know the reason for the short circuit? As shown in the figure. The input voltage of my SCREF pin is 3.2V, which is simulated using DAC output; There is a 1K resistor connected between the SCREF and DAC pins, and I don't know what the impact is? I have set the voltage to 3.2V, and the VDS protection should have been disabled.3.Secondly, I burned the same code into EVSPING4 and the board did not report any errors.   

I need to purchase a motor development kit, does ST provide it? Including control board, drive, etc. Thank you

I am having issues selecting 2 motors when creating a new project using 6.1.2.  the dropdown box only displays "1".  this functionality seems to work in workbench 5.4.8.  All of the documentation say to just select the number of motors.  I am new to this ecosystem and this is my first time using these products. thanks

Hello,I'm evaluating the STEVAL-ETH001V1 and wanted to create a project in MC Workbench for that board. Unfortunately this is not listed as an option and I also can't find a Workbench project or profile file or an STM32CubeIDE project.Is there anything that can help me configure this board in MC Workbench

Hello,I have STSPIN32F0 Based Board for PMSM motor Drive. This Motor Works for Water Pump Application. we have Created 5 step in start up sequence using  MC workbench. Motor Rotate as per Profile upto start up sequence Complete. But as soon as Motor Switch to Close Loop it start to rotate on Full Speed Suddenly and that create problem in actual application for us(some time motor stall hear OR we receive Speed Feed Back error sometime). we need to set some acceleration time. after switching to close loop it will take some time to get high RPM. Also same thing we need when we send a STOP Command, Motor deaccelerate slowly and then Stop.We can't find any solution we are trying from many days, Please let me know that how can i implement above function of acceleration and deacceleration in MC workbench Generated Code.we are using sensor less FOC drive with single shunt measurement. I am using keil IDE for Coding.. Thanks

Hi,I use a stm32f446ze to run two BLDC motors. I used the STMCWB monitor with UART port to see the bus voltage sensing there is an error of 1V and it always start with an undervoltage fault. I verified the output of the voltage divider and it's the good value. I tried to decrease the minimum voltage to avoid this fault but it didn't work. Does anybody know what's going on ?

Hi, st team,mcsdk: 6.2.1control board: nucleo-g474reBridge: XNUCLEO-IHM09M2Power Board: STEVAL-CTM009V1Motor: Motenergy ME1304Could you please advise how can I turn the current measurement from 2xICS to 3-SHunts?Thank you.

 Dear Sir/Ma’am,I am interested in the Sensor-less drive for PMSM announced by ST Micro. The technology is called ”STM32 ZeST”.I contacted ST Micro's engineering trading company, but they said they didn't know the details. Is there detailed documentation on this technology? We are considering whether it can be applied to drive PMSM, which is being considered for industrial applications.Best regards, Jun  

I have made a custom 24V drive using the STSPIN32F0 chip. For the first take on this board, I have followed the STEVAL-SPIN3201 design. I have changed the gain values for the op-amps, the MOSFETS, and a few signal inputs to the MCU. I have the custom board working and able to drive the 3 Phase 24V BLDC motor I am working with, everything is normal when using the firmware generated for STEVAL-SPIN3201 (MC Workbench 6.2.1 + CubeMX 6.8.0 + STM32 FW V1.11.4). When the feedback signals for current sensing on the reference board are: PA3  - Phase W FeedbackPA4 - Phase V FeedbackPA5 - Phase U FeedbackI swapped PA5 and PA3 on my board for layout reasons. When I generate firmware without accounting for the swapped pins the firmware runs "correctly" and the motor spins like normal. However, if I update the pins to be what is actually on the board (PA3 Phase U and PA5 Phase W) the motor essentially shorts and hits an undervoltage error due to overdrawing the supply. The generated firmwa

Hello Everyone,I have been trying to run a PMSM motor of 5 KW which is Hall Sensor based. When I try running the motor, it slightly spins after which it is not rotating. I'm using the MCSDK 6 version, also the communication between the pc and the Nucleo is continuously disconnecting. Please help me to resolve this issue...  Thanks and Regards,Sivapriya 

I'm having issues with the "busVoltageDivider" property in the "VBusSensing" feature.The Wiki says that the "VBusSensing" feature doesn't define any global propery, however the Board Manager is complaining that the property is missing when I don't add it.Furthermore, how is this and the "busVoltageDivider" property inside the "VBusSensing" hardware type (I'm assuming they're identical) calculated?The other properties "busVoltageDividerR1" and "busVoltageDividerR2" are obvious.

I am currently doing a test on the STEVAL-ETH001V1 servo drive evaluation board, where I am having problems turning on the motor. Here is the setup1- Motor (brand : dunkermotoren, PartNo : BG 42x30)-3phase EC motor, 8 pole , 24vdc, 3.3amp-with encoder2-STEVAL-ETH001V1 servo drive evaluation board3- STSW-ETHDRV01V1 firmware packageI'm using the VS GDB for debugging, however whenever I'm trying to start the motor by executing the MC_StartMotor1();, the motor tries to move, maybe trying to homing/realign the encoder. after a few seconds of doing that (with buzzing sounds), the exception thrownaccording to the explanation given, there are several commands that need to be executed before calling the MC_StartMotor1()but none of the commands mentioned in the description has been executed in the provided firmware, so do I need to do the command execution myself? if so where should I do it?

I am trying to drive a 250W BLDC motor. I started profiling the motor, which looked promesing. I based a project on the motor characteristics, but haven't been able to drive the motor as well as the motor profiler did. I have used same drive frequency:Here is the phase current when driving the motor at 2800rpm using the profiler: Motor Profiler 2800rpm (Play mode)Here is the phase currents when driving the motor at 2800rpm using my setup (notice the noise): Manual setup 2800rpm (zoom)Manual setup 2800rpm Is it possible to export the FOC Control Parameters from the Motor Profiler?  The goal is to drive the motor on a STEVAL-SPIN3201 board using Hall-sensors, but I figured I would start on the IHM08M1 board and port when I have a good control setup. I have attached the MC WB project.Informations:Motor: BLDC with Hall sensors (250W)Motor Control WorkBench: Version: 6.2.1Control Board: NUCLEO-F446REInverter Board: IHM08M1Algorithm: FOC Sensorless (Observer + P

I bought a STEVAL-ESC002V1 board and I don't know how to customize its firmware. I downloaded STM32CUDE IDE and Motor Control Workbench but none of than have a board option for STEVAL-ESC002V1 nor STSPIN32F0A. So, I downloaded the STSW-ESC002V1 which is a zip file and I don't know how to use it. It doesn't have stm32 project files or .ioc file. So, is there any tutorial I missed for that particular case? I also read the user manual and It didn't mention how to upload the firmware.  

Hi, I have one 6 pair magnet Motor can spin under profiler and workbench, however with generate code on IDE it's unable start, MOTOR STATE keep on RUN state motorState = MC_GetSTMStateMotor1();if (motorState == FAULT_OVER){ MC_AcknowledgeFaultMotor1();}if ((motorState == IDLE)||(motorState == RUN)){ MC_ProgramSpeedRampMotor1(800, 1); MC_StartMotor1();}thanks, DannyHardware : F303RE board + IHM083S

I have a BLDC motor equipped with Hall sensors. When attempting to run the motor in FOC (Field-Oriented Control) mode, I encountered difficulties achieving the required low RPM. Consequently, I configured the Hall sensors to run the motor, but encountered challenges in doing so.Ideally, I aim for the motor to operate using Hall sensors at lower RPM. After reaching a specific RPM threshold, I want the motor to seamlessly transition to sensorless control using Flux PLL.

Hello,I have an EVSPIN32G4-Dual, I am Trying to Run 2 HooverBoard Motors (36V/15A/510RPM/HALL).I generated the firmware using Mc Workbench 6.2.1 and desabled the overcurrent protection for stage 2. Then tried to command the motors using motor pilot, turning each motor separately work fine,But trying to turn one after the other, the 2 motors start shaking (didn't even start turning) ending up with one of them turning off or both, with an error of Over current in stage 1 and driver protection in stage 2.Is there anyone used this board and managed to run 2 motors simultaneously. Thank you in advance.
