Hybrid Excitation Synchronous Machine modeling using magnetic equivalent circuits

Abstract

This paper presents a 3D Magnetic Equivalent Circuit modeling of a homopolar Hybrid Excitation Synchronous Machine with distributed windings and interiors permanent magnets. The MEC model is based in a 3D reluctance element. Movement and saturation effect are taken into account. The average torque is estimated by two methods: Flux-FMM and Maxwell Stress Tensor methods. Results from the MEC model are compared to corresponding FEA computations.
