Electronic speed controller for BLDC and PMSM three phase
brushless motor
Introduction
The STEVAL-ESC001V1 evaluation board is based on the STM32F303 microcontroller, L6398 driver
and STL160NS3LLH7 power MOSFETs. It is an electronic speed controller (ESC) designed to drive a
single three phase brushless motor (BLDC/PMSM), performing a sensorless FOC algorithm with speed
regulation and active braking function. This unit can accept commands from an external unit for driving
and monitoring a flight control board, for instance. For this purpose, several communication bus
interfaces (UART, CAN, I²C) are available.
The board includes a BEC 5 V circuit and embeds an overcurrent/overvoltage and thermal protection
circuit. Its form factor renders it suitable for small and light R/C vehicles and its motor current capability
meets the power requirements of larger vehicles like professional drones.
