A Novel 12/10 Electrical Excitation Flux-Switching Machine

Abstract:

A three phase, electrical excitation flux-switching (EEFS) brushless ac machine is proposed, its electromagnetic performance, viz., the phase flux-linkage and back-EMF waveforms, the torque density, the electromagnetic torque, and the torque-current characteristic, are evaluated based on finite element analysis. An EEFS machine exhibits sinusoidal flux-linkage and back-EMF waveforms. Compared with a hybrid excitation flux-switching (HEFS) machine, when de-excitation at fault is needed, the torque density of EEFS machine is ~20% larger than that of a HEFS machine with the same armature and field current copper loss.
