Eddy current sensor simulation
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017Purpose This paper aims to present a simulation concept and an experimental verification of a novel sensor design for the shaft position measurement based on the eddy current principle and the phase-shift measurement. The simulation method for the sensor characteristic determination is presented.

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 ...

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.

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 ...

An Analysis Of Eddy Current Testing With Sheet Current
[1993] Digests of International Magnetics Conference, 1993The eddy current problem of recognizing a crack on the edge of a rivet hole is analyzed numerically by using the current vector potential method. The vertical field is induced by the disturbance of the sheet eddy current on a thin plate. The vertical field is evaluated for a visualization technique with magnetooptics.

Physical Mechanism of Eddy Current Demagnetizing Effect for Eddy Current Brake
Journal of Computational and Theoretical Nanoscience, 2016This article researches both the mathematical relation between the braking force of eddy current brake and the speed of the moving conductor and the relationship between the average air-gap flux density and the velocity of the moving conductor respectively which result in the ambiguity of the physical mechanism of eddy current demagnetizing effect ...

The study on the measuring method of the eddy current on the eddy current brake
9th International Conference on Electrical Machines and Drives, 1999It is important to analyse the characteristic of the flux density and eddy current on the inner part of the electric machine in order to raise the efficiency of the machine. In general, characteristics of the machines are investigated using the numerical analysis.

An experiment which shows negligible reaction from eddy currents in iron on their inducing field is described. The observations are shown to agree with the extension of Searle's results for the magnetic field of a long current filament in iron to an aggregation of current filaments such as eddy currents.

Deep Sea Research Part II: Topical Studies in Oceanography, 2005
Abstract Measurements by a variety of sensors provided details of flow in Haida Eddies, which are anticyclonic, mesoscale features that move slowly westward through the eastern Gulf of Alaska. These measurements provided the best comparison and analysis to date of mesoscale eddy currents by various ship- and satellite-based sensors.

Symmetric Coupling for Eddy Current Problems
SIAM Journal on Numerical Analysis, 2002Summary: A novel symmetric finite element method-boundary element method-coupling for the \(\mathbf{E}\)-based eddy current model is derived in a rigorous fashion. To that end, the properties of potentials and boundary integral operators arising from a Stratton-Chu-type representation formula for the electric field in the nonconducting region are ...
