STM32 MCUs Motor control

ich verwende MCSDK 6.2.0 ich versuche seit einigen Tagen ein Maxon-Motor mit B-G431B-ESC1 zu drehen. aber es gelingt bisher nicht. Könnte jemand mir bitte sagen , was ist falsch eingestellt habe? ich habe mit Workbench alle Parameter von meinem Motor eingegeben . ich will die mit 14 V betreiben. und dann die Projekt generiert . mit Hilfe von STM32CubeIDE 1.13.2 die generierte Code in dem B-G431B-ESC1 geflasht und bisher keine Fehlermeldungen gesehen. alles scheint gut zu funktionieren. Ich erwarte dass, der Motor sich mit ST Motor Pilot V1.2.4 dreht . aber das ist nicht der Fallt. Der Motor macht nur so komische Geräusche aber dreht sich nicht. Es wäre so nett, wenn Jemand die Zeit nimmt, um mich eine Rückmeldung zu geben.  im Anhang den Datenblatt meinem Motor und .stwb6 Projekt. Mit freundlichen Grüßen 

I have imported the motor details from motor pilot and workbench, but now the main challenge is to set the speed in the code is there any direct api to change the speed in rpm in the code?used the below api for starting the motor, it ran smoothly. I want to change the speed next how can i do itMC_StartMotor1();

I got error mentioned below. How to resolve it. I am using x-nucleo-ihm08m1 with STM32f303re control board for six-step 

Hi All ,I need to change  phase 120 degree to 90 degree in MotorControl Workbench 6.2.0 Can change in file mc_math.c?For use single phase motor 3 wire  Please help me for advice. BR,METHEE

Hi everyone!I am trying to run the B-G431B-ESC1 board for the first time (also it is the first time I am using STm software tools) and ran into this issue. I tried compiling for other boards and even other exemples and none of them generated the mcp.h file in the includes folder. Am I missing something? Did anyone ever had this issue before?Thanks in advance!MC Workbench v6.2.0CubeIDE v1.14.0 

Howdy. Sorry to have an issue on my first post. I just purchased and programmed a Nucleo 401re to drive a SimpleFOC shield for open loop bldc motor control. I originally used a 2015 Arduino Uno with excellent results, 0.1% speed variant on the vinyl turntable it drives. With the 401re I get 1.4% variation which renders it useless and wow and flutter are equally poor.Does the 401re require different parameters. The SimpleFOC info does not indicates any changes as the porting is identical and the motor does work, just poorly.Many thanks.

Dear STer        I use MCSDK 6.2 ，I want  use  UNCLEO-G431RB + X-NUCLEO-IHM07M1   profiler motor model ，but open “motor profiler” ，Control Board and Power Board is blank。

Hello,I have a 48V motor and would like to evaluate this design using the STEVAL-SPIN3201 which is only rated to 45V.The schematic sort of suggests that if you remove the JP2 jumper you can independently supply VM and VBUS, and VBUS can go to 60 volts due to FET's limit and VM can go to 45V.I removed this jumper and connected 48V to J2 for VBUS, and 24V to J1 for VM.Changed the FW so I don't get overvoltage error and the SPIN32F0 programmed fine. But as soon as I commanded the motor to run the board burned out, appears to have burned at the VM input of the SPIN32F0.Has anyone successfully provided separate VM and VBUS with this EVAL board?Because I am just barely over the rated voltage, and the absolute maximum rating of the SPIN32F0 is actually 48V, I doubt the board burned up because the higher voltage, I suspect the 2 supplies are fighting each other somehow and I did not make all the changes to the board I needed to.I had previously run this motor with this board at 42V fine, so I

Hi CommunityI hope someone can help me. I am about half way to getting my spin3201 to work but it does not run consistantly. Using motor pilot I can get it to start rotating and it ramps up but then goes into faultmode and drops out with speed feedback fault. I can configure the speed to hall effect and my motor is hall effect type, but whether i configure it or not, it still bombs out with this fault.So starting at the beginning, when i load the STEVAL_SPIN.ioc ver 6 in the cubemx, i notice that i have the following conflicts, from the start are flagged1) RCC, Reset and Clock ControllerstatusPartly disabled conflict with :TIM1; Channel 1 PWM Generation CH1 CH1N or/and PF0-OSC_IN mapped with GPIO_EXTI0Partly disabled conflict with tmr1; Cannel 1 PWM generation CH1 CH1N or/and PF0-OSCWhen i examine this problem it seems deeply ingrained in the actual program where i cant change one thing without it affecting something else. I know i am missing something , I am sure the software can

Hello, I put all values of pole pair speed current etc as show in below screenshotbut while during i start the profile speed feedback error i getplease let  me know what is the problem

Hi, Im very beginner for MotorWorkBecn tool.I faced with error in the generarion step, like attched photos.Generation step- Completed with errors."......MCPackNotFound......" I'm trying to drive with EVSPIN32F0602S1.MotorControl Workbench V5.4.8 How Can I solve this error. Kinds Regards,Bryan Shin

How to find the value of Rs, Ls and B-emf constant and sensor displacement , placement electrical angle please let me know as soon as possible

Hello,I'd to drive two 3-phase BLDC with FOC & Hall on EVSPIN32G4-dual board, generated the code from MCSDK6.2 (support dual motor control).First, I control the M1 motor only, it's well, then stop the M1 and control the M2, it's also well.But when I control the M1 first and then wait for seconds to control the M2, the M1 and M2 both are unstable & vibrating. Measure the PWM signal from gate driver STDRIVE101, found the PWM signal is anomaly.I cannot figure out the reason, is it caused by concurrent FOC or some else? Can someone give some advice, thanks. 

Hello,I'm planning to design a motor driver using the STSPIN32 IC on the evaluation board EVSPIN32F02Q1S1 and was going through the schematic when I noticed this current sensing circuit:I understand that R34, 36, and 111 are used as single shunt sensing, but I don't get why what the point of having R33 and C22, are they for some form of biasing?I'm also unsure of the function of R38 and R57.Basically, can someone explain what the point of having R33, C22, R38, and R57 as part of current sensing circuit?

In the R3_2_GetPhaseCurrents(), the following line reads the ADC data register.hReg1 = *pHandle->pParams_str->ADCDataReg1[bSector] * 2;The value of the hReg1 will be used to compute the phase current later. Why is the value of the ADC data register multiplied by 2?Thanks in advance.

Posted on March 05, 2016 at 22:10Could you describe how to set ''Placement electrical angle''. The default value in ST Motor Workbench is 300 degrees.I have an 8-pole motor with 120 degree spaced hall sensors. I have this set to 60 degrees based off information I found online and I get the most torque at that setting as well. I'm interpreting it as the angle difference between different hall states.I ask the question because the value of ''Placement electrical angle'' can be from 0 to 359 degrees and I'd like to understand when that changes. From my understanding a value other than 60 degrees shouldn't work properly if using 120 degree spaced hall sensors...but that must not be the case hence the option in ST Motor Workbench.Regards,Sagar

I'm using a STM32F4 and MC SDK 5.4.8 to control a BLDC motor from MAXON, when start the motor without load, the motor can be started everytime, but sometimes it will stucked with a load, the motor control status is still RUN, but the motor will not run, if I push the load, then the motor can start, anyone can share some advice, thanks.

What is speed feedback error fault in motor control workbench?

Hardware : STM32G431RB + X-NUCLEO-IHM07MICurrent feedback : 3 shunt​SDK : MCSDK version 5.4.6Control mode : Position control High frequence : 25KHZMediumn frequence : 1KHZIn below image green circle can see that my motor start to move always jump one degree.I try 3 different motor also have this problem.Can someone help why it happens or how to deal with it.​Thank you!

i got a STEVAL-CTM010V1 board and installed the SDK(5.4.4 full),after that i created a project base on example(STEVAL-CTM010V1 dual drive with PFC,see pic_1),but the example does not enable the PFC feature(see pic_2),so if we want to use the PFC feature on CTM010V1 board ,what should we do ?

I used like reference the document:https://www.st.com/content/ccc/resource/technical/document/user_manual/group1/48/e6/91/f4/66/ea/48/a1/DM00490980/files/DM00490980.pdf/jcr:content/translations/en.DM00490980.pdfI use:STEVAL ESC001V1Motor Control Workbench 5.4.8Motor Profiler 5.4.8STM32CubeIDE 1.8.0STM32CubeMXFirstly, I generated a code in Motor Control Workbech. In this code, I wrote the next code to run my motor but it didn't work. I don't know why because it didn't have any errors. At the same time, I used "MC_GetSTMStateMotor1();" which showed me that I have 2 faults. I need help pls!!Kind regardsMy code: You Currocan see the state motor here: 

Hi,I made some temperature measures on STSPIN32G4 using a thermal camera.I saw that the central part 3x3mm of the STSPIN reaches about 70°C, while the sorrounding part does not go beyond 50°C.My question is the following: if I use the internal temperature sensor I will read the temperature of the central part or the sorrounding part? Thank youFederico

how we can change the speed of motor in STEVAL -SPIN3201 using external Potentionmeter?/or inbuilt Potentionmeter (Variable resistor )?

In my application, I am driving a low voltage, low speed PMSM with a custom power electronics board. Using motor control workbench, I have a configuration where I can reliably start the motor and it spins up to speed.However, the reported speed thorugh the console seems lower than actual speed. For example, the console reported speed is oscillating between 100 - 150 RPM, but the measured frequency of the current waveforms, as well as the observer electrical angle indicate a frequency close to 20 Hz. The motor is a 10 pole motor; therefore I expect 240 RPM at 20 Hz. I am in the process of trying to independantly confirm the speed using an encoder, but this test setup is ready yet.Once question I have is my operating speed too low for the observer? Is there some information on the observer available that defines its ideal operating range?Finally, is there a way to set the motor control to run open loop?
