Abstract
Brushless DC (BLDC) motors are one of the electrical drives that are rapidly gaining popularity, due to their high efficiency, good dynamic response and low maintenance. In this paper, the modeling and simulation of the BLDC motor was done using the software package MATLAB/SIMULINK. A speed controller has been designed successfully for closed loop operation of the BLDC motor so that the motor runs very closed to the reference speed. The simulated system has a fast response with small overshoot and zero steady state error.

1．介紹
20世紀80年代末以來的永磁無刷電機新的設計概念已developed.The永磁無刷電機可分為點名的反電動勢波形，它可以在任何無刷交流（雙語）或無刷直流（BLDC操作）模式。通常雙語電機有一個正弦反電動勢波形和直流無刷電機具有梯形反電動勢。在現(xiàn)代工業(yè)生產(chǎn)的電機無刷直流（BLDC）電機正在迅速獲得普及。無刷直流電機應用于行業(yè)，如家用電器
