Resolved! Safe Limited Speed with STM32 microcontroller

Hello I am working on a 48V BLDC drive unit and I would like to implement the safety feature "Safe Limitd Speed" according SIL2/3 and PLc/d.In the Motor Control Reference Guide from ST there is "Safety ready: SIL, Class B" as one of the key features ...

Stm32 ADC trigger at certain time

Hello friends, i want to read ADC value for particular time. That is, to read the analog value during the middle time of every pwm signal. Triggering ADC via timer.I had generated pwm signal with 50% duty cycle in center align mode so that we could e...

Resolved! BLDC back emf problem using Motor Work Bench

We're in the process of designing BLDC motor controller for solar pump (1HP and 2HP), we plan to use `STGIB15CH60TS` IPM to drive motor and `STM32F103RC` as controller. We started design using `MotorControl Workbench 5.4.4`, however in this we are no...

Resolved! how to calculate gains like (PID_SPEED_KP_DEFAULT,PID_SPEED_KI_DEFAULT,PID_SPEED_KD_DEFAULT) and speed PID parameter dividers like (SP_KPDIV) in PMSM motor STM32 , in STEVAL-ESC001V1

STM32F303CB Motor control setup can't avoid stalling

Hi,I am using the STEVAL-ESC001V1 development kit board with a BlueRobotics T200 motor. The motor runs well with the provided SDK firmware and the motor profiler values, but we are having a couple of issues when changing speeds:The range of the poten...

Resolved! Is anyone able to drive a BLDC motor at low speeds? anything below 6 RPM?

I am using the X-NUCLEO-IHM08M1 as a power board and NUCLEO-F303RE as a control board. Using an incremental encoder of 1024CPT I was able to drive the motor as slow as 6RPM, even after several attempts I was unable to achieve any lower speeds. When I...

Resolved! ST motor control SDK - FEMA (Failure mode effects analysis) document

We are working on a project that uses ST motor control library. As part of our project requirements we have to do a FEMA for the software. Does anyone know if there is a FEMA document for ST motor control library?

Resolved! I'm trying to build a PID controller for a BLDC motor. Is there any support to input the constants while the processor is in the loop?

Resolved! How can I do to count motor steps with Input Capture Direct Mode with DMA?

I want to count the steps that the motor takes with DMA and when it reaches a certain number of steps, turn off the PWM timer. How do I read the incoming pulses?

Resolved! Encoder feature in STM32F070CB

Hello,I need a help in Motor frequency calculation with more precision. I am using STM32F070CB for my application. My requirements are1) Monitor the Motor frequency based on quadrature pulses.2) If Frequency varies by +/-15%, need to process some saf...
