How to write a Motor control post to get a response quickly

In order to have a quick response to your forum posts, the best way to ask the question is:- Give the version of the MCSDK used. - Say if the problem concerns a tool (MC Workbench, Motor Pilot, Motor Profiler, etc...) - Provide picture of tools inter...

Resolved! Another undefined reference issues with MC SDK and C++

I've been trying to develop a C++ application which uses the C based MC SDK (would really be nice if STM would provide a supported wrapper). I'm getting:arm-none-eabi-g++ -o "nucleo_demo_y4.elf" @"objects.list" -mcpu=cortex-m4 -T"C:\Users\dustin\re...

(Bug Report) When using encoder, the generated code has a few defects - speed calculation is not reliable, no speed reliability check, and no scheme to clear speed feedback fault

Bug report :Max speed with Hall sensors

Dear MCSDK team,We met a difficulty using Hall sensors as our primary speed and position sensor.When setting a mechanical speed higher than UINT16_MAX / nb_pair_poles / 2 the value of hMaxReliableElSpeedUnit is overflowing in the Hall_Init function. ...

Hello, I want to control a low voltage BLDC sensorless motor so I bought a nucleo-ihm11m1 card as I have an Arduino board and I saw in the datasheet that it is Compatible with Arduino UNO R3 connector. But for programming the arduino I'm stucked.

Resolved! Hello, I am using the STEVAL-ESC001v1 board with a BLDC motor. I would like to use the Hall sensor mode but I cannot access the pin selection for the Hall sensors in the MC Workbench Does anyone have an idea on how to solve this issue ? Thank you.

Hi, I am working on an ACIM motor 4 pole, I discovered that there is a software example based on STEVAL-IHM023V3. As the motor is a 48 volt 10 Amps I'd like to drive it with B-G431B-ESC1, is there some firmware porting available or a guide to do this?

STSPIN32F0: Why does BLDC Motor stop with a Speed Feedback Fault on Loading it?

Hello All,I am using STSPIN32F0 controller to run a BLDC motor at 1400 RPM. I am using ST Motor Control Workbench and IAR IDE for my project.Motor Design Specs:Rated Voltage: 36VRated Current: 10AmpRated RPM: 1400 RPMMy Motor Starts without any issue...

How can I increase the current rating in evspin32f0602 based custom boad

On what does the value of resistor r41 and r55 depend I tried increasing shunt resistance but the measured current value when I start the motor is very high.I am not getting the current value accurately.The motor spins in open loop and when it shi...
