Modeling and control of an eddy current brake

open access: yesControl Engineering Practice, 1996
The purpose of this paper is the application of some existing techniques for the modelling and regulation of an eddy current brake process. An approximate theoretical model is derived for the behavior of an eddy current disc brake in the low-speed zone.

Physical Mechanism of Eddy Current Demagnetizing Effect for Eddy Current Brake

open access: yesJournal of Computational and Theoretical Nanoscience, 2016
This 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 ...

Characteristics of Eddy Current Braking

open access: yesASME 2010 Rail Transportation Division Fall Technical Conference, 2010
Eddy current braking has long held the promise of frictionless braking of railroad trains. The advantages of eliminating friction brake equipment are particularly valuable to high speed rail passenger service. Tests over the last decade have identified a number of controllable challenges to implementing eddy current brakes involving the vehicle, track,

An Alternative Approach for Calculation of Braking Force of an Eddy-Current Brake

IEEE Transactions on Magnetics, 2009
We have analyzed an eddy-current brake (ECB), using calculations based on the Fourier transform method. Here, we compare our results with test results and numerical results of the finite-element code ANSYS 11.0. We use our model to study the influence of certain design parameters on the torque-speed characteristics.

Characteristic of eddy current on the secondary of eddy current brake

1997 IEEE International Electric Machines and Drives Conference Record, 2002
An 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.

Eddy current brakes

Journal of Scientific Instruments, 1935
A study of the properties of eddy current brakes suggests some lag effect in the action of eddy currents which increases with frequency. Using this conception, a theory is given to account for the results obtained and to evolve a convenient mode of presenting them graphically.
