Using STM32 motor control workbench with STSPIN32F0
Introduction
The STSPIN32F0 and STSPIN32F0A are systems-in-package providing an integrated
solution suitable for driving 3-phase BLDC motors using different driving modes. The
integrated MCU (STM32F031x6) allows the performance of field-oriented control.
This document explains how to drive the STSPIN32F0 or STSPIN32F0A with FOC
algorithms, using the STM32 motor control workbench software to generate all the
parameter header files, to configure the STM32 PMSM FOC library according to application
needs.
To drive a motor with FOC algorithms using the STSPIN32F0 or STSPIN32F0A device,
follow this simple workflow:
1.
Set up the hardware.
2.
Use STM32 motor control workbench to configure the library and generate the code.
3.
Create the library and download the firmware.
4.
Control the motor.
