Modeling of Axial Flux Permanent-Magnet Machines

IEEE Transactions on Industry Applications, 2004
In modeling axial field machines, three-dimensional (3-D) finite-element method (FEM) models are required in accurate computations. However, 3-D FEM analysis is generally too time consuming in industrial use. In order to evaluate the performance of the axial flux machine rapidly, an analytical design program that uses quasi-3-D computation is developed.

A Simple Nonlinear Magnetic Analysis for Axial-Flux Permanent-Magnet Machines

IEEE Transactions on Industrial Electronics, 2010
This paper presents a simple nonlinear magnetic analysis for axial-flux permanent-magnet machines as an assistant design tool of 3-D finite-element analysis (3D-FEA). The proposed analysis consists of an equivalent magnetic circuit and an analytical model of air-gap permeances, including saturable permeances in the core.

Influence of magnetic wedges on the no-load performance of axial flux permanent magnet machines

2010 IEEE International Symposium on Industrial Electronics, 2010
Aim of the paper is to evaluate a particular aspect of the design of axial flux permanent magnet (AFPM) machines, i.e. the use of SMC wedges to close stator slots. This contribution is the continuation of a previous investigation dedicated to the analysis of the no-load performance variation introduced by the magnetic wedges. Here, attention is focused

FEM evaluation of performance of axial flux slotted permanent magnet machines

Conference Record of 1998 IEEE Industry Applications Conference. Thirty-Third IAS Annual Meeting (Cat. No.98CH36242), 2002
Axial-flux permanent magnet machines with slotted windings exhibit a significant cogging torque due to the magnetic anisotropy of the stator. The same produces a harmonic content in machine back EMF. The paper introduces and discusses a simple and powerful FEM algorithm that gives a numerical evaluation of both cogging torque and back EMF.

Analysis of Axial-Flux Halbach Permanent-Magnet Machine

IEEE Transactions on Magnetics, 2015
This paper presents a 3-D analytical magnetic field analysis of an air-cored axial-flux Halbach permanent-magnet machine (AFPMM with Halbach). The 3-D analytical magnetic distribution is established using the magnetic scalar potential and modified BESSEL functions in the cylindrical coordinate system. The analytical magnetic field distributions and the

Electromagnetic design of axial-flux permanent magnet machines

IEE Proceedings - Electric Power Applications, 2004
A general, analytic approach to the calculation of magnet fields in a slottless, axial-flux, permanent magnet generator is presented. The basic 'building block' is the vector potential produced by a current sheet situated between two, infinitely permeable, iron surfaces.

Thermal modelling of an axial flux permanent magnet machine

Applied Thermal Engineering, 2004
Abstract The imperative for conserving energy highlights the need for considering the more widespread implementation of higher efficiency electric machines such as the axial flux permanent magnet (AFPM) machine. Because of their compact geometry and high power densities, the cooling of these machines is important.
