Board Manager documentation is out !

The documentation of the Board descriptions format is now available on Motor Control Boards Description Wiki page, this documentation is compatible with MCSDK versions from 6.1.2. Board Descriptions are used by the ST motor-control workbench to enabl...

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...

Change frequency of TIMER for acceleration deacceleration of motor

I'm driving 3 stepper motor using STM32F030C8T6TR MCU 3 different TIMERS I want to acceleration deacceleration motor so for that I want to change TIMER frequency and count pulses output at chanel how can I do it?Example :Motor travel distance 10000 ...

I am using STM32g431CB for running a BLDC motor with TIM1 for PWM generation and TIM4 for hall sensor output with hall sensor mode. My motor is running now.I want to measure the rpm of the motor.How can i measure the rpm of motor using hall sensor?

Issues with Motor Control SDK

I have a BLDC 24v 2.7 v/kprm 1.5 ohm 2.1mH device with a 200 CPR 2 channel single ended incremental encoder. I am using a NUCLEO-L476RG and X-NUCLEO-IHM08M1. I seem to have an issue with some of the terminology used. First the motor control SDK ment...

Resolved! (Bug Report) Dual drive code appears in R3_2_TIMx_UP_IRQHandler() / r3_2_f4xx_pwm_curr_fdbk.c when using single drive configuration

(Environment)MC_SDK 5.Y.3 + STM32CubeMX 6.3.0 with HAL + IAR EWARM 8.5(Hardware)custom board based on F446RE + custom power board + Low Voltage BLDC motor with Encoder(Control Mode)Speed Control(What I found)I configured a single drive, where TIM1(P...

Resolved! Is it possible to start the motor under heavy load in FOC mode?

I use Hall sensors as speed feedback, is it possible to correctly start the motor when it is under 100% load.Or need to apply special methods for initial increase in speed like 6-step control?I have attached several oscillograms that I found about th...

Hello, I want to run a stepper motor using STM32F412 discovery board at its rated max speed. I am wondering if there are any compatible stepper libraries for that.

Large current surges when the Hall sensors move to a new sector.

I use B-G431B-ESC1, MC 5.Y.3 and Hall sensors as main feedback. I am getting large Id and Iq current peaks when the Hall sensors are switched. This apparently leads to the operation of the current protection, as well as a weak torque.The graphs are d...

Dissipative Brake option

I have checked the dissipative brake option after generated codes, I couldn't find any different with without option checked ? What's this option for ? thanks,Danny
