Magnetic Equivalent Circuit Modeling of an Axial-Field Magnetic Gear

Abstract

This paper presents a two-dimensional (2D) magnetic equivalent circuit (MEC) model to investigate the magnetic field distribution in the air-gap of an axial-field magnetic gear (AFMG). The MEC model is configured as a meshed reluctance network (RN) with permanent magnet magnetomotive-force sources. The MEC model based on RN is considered as a good compromise between accuracy and computational effort. This is a new model that will allow a faster analysis and design for the AFMG. Flux density in the air-gap is calculated with the proposed model and verified by finite element simulations.
