D-q axis inductance characteristics of the consequent-pole motor

This paper analyzes the d-q axis inductance about the consequent-pole motor (CPM) under different current excitations. Based on the relationship of the inductance and the current between the three-phase and the d-q axis, the inductance of the d-q axis are analyzed by finite element method (FEM) in the static magnetic field. The inductance is obtained under three different conditions of loading only the d-axis current, the q-axis current and loading the d-q axis current simultaneously.
