Abstract

Nonlinear and anisotropic magnetic fields in a high density Axially-Laminated Anisotropic (ALA) rotor reluctance machine are computed by the finite element method. Different position angles between stator current vector and rotor d-axis (from 0° to 90°), different pole span lengths (from 2/3 pitch to full pitch) and different applied currents (from 0 to 2 times the rated value) are investigated. Based on numerical results, the parameters and performance of this machine are calculated and discussed. Conclusions show that in order to achieve linear parameters and high performance, the per unit value of the magnetizing current should be less than 0.5 and the pole span length should be optimized
