Error Analysis of Position Detection for Sensorless Permanent Brushless DC Motor Position Detection
摘要
Abstract
In sensorless permanent brushless DC motor control systems based on back-EMF zero-crossing detection,non-conducting phase voltage was distorted and back-EMF zero crossing phase was shifted due to low pass filter and diode freewheeling.This problem was proved by math model,simulation and experiment,then a method of using AD module to detect back-EMF zero crossing was presented and finally the method was proved by experiment results.关键词
