Research on Back Electromotive Force Phase Compensation of High Speed Sensorless Brushless DC Motor Control
摘要
Abstract
The sensorless brushless DC motor has the characteristics of simple structure,perfect performance of speed regulation and high efficiency,which had become the first choice for the horizontal well tractor.According to the actual working conditions,due to the speed of the brushless DC motor used by retractor was higher,so the back EMF zero crossing point would caused a certain phase shift angle,which lead to deviate from the commutation point of the motor from the best commutation phase point.Aiming at this problem,researched on the phase compensation of back EMF,and proposed a dynamic phase compensation method to realize the best commutation of the motor,which ensured the smooth running of the motor.The experimental results showed that the proposed method could achieve the "best commutation logic",which made the motor running smoothly,and the variable speed range became larger.关键词
