Getting started with the STEVAL-SPIN3202 evaluation board, advanced BLDC
controller with embedded STM32 MCU
Introduction
The
STEVAL-SPIN3202
three-phase brushless DC motor driver board is based on the
STSPIN32F0A
3-phase controller with
integrated STM32 MCU and
STD140N6F7
MOSFETs.
It implements a single shunt resistor current reading topology and provides an easy-to-use solution for the implementation of
home appliances, fans, drones, power tools, and low voltage motor driving applications.
The board is designed for sensored or sensorless vector control FOC and six-step algorithms with single shunt sensing.
