摘要
介绍了节能空调用无刷直流电机的原理及数学模型,提出了基于符号检测的反电动势过零点检测方法,设计了基于dsPIC的无位置传感器控制系统,并给出了节能空调用无刷直流电机控制系统软、硬件结构及实现方法。
This paper introduced the working principle and the mathematical model of BLDC motor used in an energy-efficient air-conditioner,presented a new rotor position detecting method and designed a sensorless control system based on dsPIC.The software and hardware architecture and implementation of the control system are provided as well.
