Abstract

This paper highlights the future perspective for novel hybrid radial-axial flux structure magnetic gear, named arcuate double-sided magnetic gear (ADSMG) with the aim of higher torque density transmission. Its performance characteristics are quantitatively analyzed using an improved quasi 3-D analytical method (IQAM) computations of magnetic field (which is an improved and amended of 2-D analytical method). Results are verified by 3-D finite-element method simulations to enhance the reliability and precision of the analysis. This modeling is carried out by an effective dependent modeling for the different components of magnetic field distribution, based on axial and radial flux magnetic gear topologies, and modified to accurately model the proposed ADSMG structure. Utilization of proposed IQAM for optimization of ADSMG in a typical wind power application is investigated. It is shown that the optimized ADSMG has significant and superior advantages in terms of torque density than the traditional MGs.
