Open full text 2 citations

Abstract

Brushless DC motor applications are very extensive. This article is about the sensorless brushless DC motor using back EMF zero crossing detection of rotor position detection method. Proposed two kinds of terminal voltage and phase voltage back EMF zero crossing detection method to detect the rotor position, thus completing the motor control.
