摘要
本文介绍了几种无位置传感器无刷直流电动机的转子位置检测方法,并对它们的基本原理,优缺点作了简单的说明,详细地阐述了基于一种新磁链函数之上的与速度无关的位置函数控制方法,利用这种方法从零转速到高转速的宽速度范围内能检测到转子位置。
This paper presents several control methods for BLDC motor, and describes their fundamental principles ,advantages and disadvantages in brief. The method of speed-independent function,based on a new flux linkage function,is explained in detail. This method makes it possible to detect the rotor position over a wide speed range from near zero to high speed.
