摘要
本文介绍了基于单片机PIC16F877的直流无刷电动机控制系统。主要分析了反电动势感应方法,并阐述了虚拟中点法和三段式起动技术。
This paper present a sensorless and BLDC motor control system based on PIC16F877. The technique of back EMF induction in BLDC motor is analyzed, the “virtual neutral point” method and the technique of “3 -step” start are introduced.
