A high-frequency signal injection based sensorless drive method for brushless DC motor

Abstract

Inductance saliency-based position sensing method is a common complement to the ineffectiveness of the traditional back-emf-based methods in low-speed applications, which effect originates from zigzag saturation on core teeth. In this paper, an impedance-tracking based self-sensing method is proposed, which is capable of quickly estimating rotor position by… (More)
