Mirror-Phase Characteristics of Synchronous Reluctance Motor and Salient-Pole Orientation Methods for Sensorless Vector Controls

Abstract

In this paper, first of all a mathematical model of synchronous reluctance motor in a new form is established, secondly a new analysis of stator linkage flux of the motor is given, which characterizes the motor and plays the essential role for developing new rotor salient-pole orientation methods for sensorless vector controls. Finally in a unified manner based on the inherent characteristics of the flux, six new potential salient-pole orientation methods are developed and proposed.
