Performance Evaluation of an Axial Flux Machine with a Hybrid Excitation Design

Variable speed, permanent magnet synchronous machines with hybrid excitation have attracted much attention due to their flux-control potential. In this paper, a design of axial flux iron poles in the rotor and an additional electrically controlled source fixed on stator is presented. This paper shows results pertaining air-gap control, electromagnetic losses, torque, back emf efficiency maps obtained through field-strengthening weakening operations investigated by 3D finite element analysis. Moreover, temperature distribution machine was analyzed according fluid–thermal coupling method. The presented prototyped experimentally tested validate effectiveness numerical models achieved results.
