Eddy currents: theory and applications
Proceedings of the IEEE, 1992The theory and applications of eddy currents induced in conducting materials by time-varying magnetic fields are reviewed. The mathematical methods employed in solving the relevant problems are presented. Both analytical and numerical methods are described. Applications based on effects arising from eddy currents are discussed in detail.

Characteristic of eddy current on the secondary of eddy current brake
1997 IEEE International Electric Machines and Drives Conference Record, 2002An eddy current brake is a new assistance brake system of a large scale vehicle, and the eddy current plays an important role in the braking force of this brake. This paper presents a new calculating method based on the experiment, while the eddy current problem, generally, is calculated by using FEM.

Computation of 2D and 3D Eddy Currents of Eddy Current Retarders
2010 International Conference on Electrical and Control Engineering, 2010this paper deals with the A-_-A formulation applied to problems where motion is the source of eddy currents. The Lorenz gauge is used to ensure uniqueness of the solution and leads to a two-step computation procedure: A is computed first followed by _ on moving regions only.

Experiments with eddy currents: the eddy current brake
European Journal of Physics, 2004A moderate-cost experimental setup is presented to help students to understand some qualitative and quantitative aspects of eddy currents. The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy by generating eddy currents. A set of simple experiments is proposed to measure eddy current losses

Formulation of the eddy-current problem
IEE Proceedings A (Physical Science, Measurement and Instrumentation, Management and Education), 1990A critical survey on some of the principal approaches to the solution of the general three-dimensional eddy-current problem is presented. The two main families of formulations, those magnetic and those electric, are discussed, with reference to both mathematical and computational aspects.

Eddy Current Loss Calculation for Permanent Magnet Eddy-current Coupler
2020 7th International Conference on Information Science and Control Engineering (ICISCE), 2020This paper presents an analytical method for calculating the eddy current loss of permanent magnet eddy-current coupler (PMEC). A magnetic equivalent circuit (MEC) model considering the eddy current effect and leakage is established. Then, based on Kirchhoff’s law and Ampere’s law of loop, the flux density passing through the conductor rotor and the ...

Magnetic field and eddy current analysis of permanent magnet eddy current coupling
2015 IEEE International Conference on Information and Automation, 2015The magnetic field distribution and eddy current density of the permanent magnet eddy current coupling has a great influence on the performance of the coupling. If the air gap between the inner and outer rotor is far less than the axial size, and negligible side effect, then the coupling of magnetic field can be simplified as a two-dimensional planar ...
