Non-Linear 3-D Semi-Analytical Model for an Axial-Flux Reluctance Magnetic Coupling

Abstract

This article presents a 3-D semi-analytical model of an axial-flux reluctance coupling. Thanks to the separation of variable s method, Fourier series analysis and the convolution the orem (i.e. Cauchy's product), the salient-pole region is modelled by a spatially variable magnetic permeability. Additionally, an iterative algorithm is implemented to account for the magnetic saturation of the iron teeth. The results of the proposed model are compared with a previously published 2-D se mi-analytical model, 3-D finite-element method and e xperimental results. The proposed method appears to be an appropriate tool for the design process of reluctance couplings in cases where the salient poles are saturated.

A Review of Recent Developments in Permanent Magnet Eddy Current Couplers Technology

“…There are many improved types of devices using the same operating principle, such as those with linear motion [43][44][45], those using electrical excitation [46][47][48][49] and hybrid excitation [50], and high-temperature superconducting materials that make PMs to enhance magnetic fields [51]. On the conductor rotor side, superconducting materials [48,[52][53][54][55], ferromagnetic materials [56,57], and PMs [58][59][60][61][62][63][64][65] on the conductor disk side are used. These structures are out of the scope of this paper.…”
