于无刷直流电机的驱动的基本原理，很多教材和文档都已经讲得很清楚了，特别是坛上网友提供的：《无刷直流（BLDC）电机基础》（MicroChip公司，编号AN885）、《Brushless DC Motors Made Easy》（Freescale公司，编号PZ104）和Atmel公司的编号为：AVR194、AVR491、AV R 4 9 2的几篇文档，都写得很不错，深 ...
本应用笔记介绍一种采用dsPIC数字信号控制器（Digital Signal Controller，DSC）或PIC24单片机来实现无刷直流（Brushless Direct Current，BLDC）电机无传感器控制的算法。该算法利用对反电动势（Back-Electromotive Force，BEMF）进行数字滤波的择多函数来实现。通过对电机的每一相进行滤波来确定电机驱动电压换相的时刻。 ...
