This paper presents a comparative study of three types of doubly salient machines (DSMs), i.e. wound field variable flux machines (VFMs), hybrid-excited stator slot permanent magnet machines (HSSPMs), and stator slot permanent magnet machines (SSPMs). Two dimensional finite element (FE) modelling is carried out to investigate the electromagnetic performance of the VFM and the SSPM based on a global...
This paper investigates the armature reaction field and inductance feature of the hybrid excitation synchronous machine (HESM) with magnetic shunting rotor and brushless field excitation. It is shown that introduction of excitation winding has a significant effect on armature reaction of the HESM. Inductance feature is determined by the saturation of both axial and radial flux path which vary with...
