An eddy current braking system

1993 (25th) Southeastern Symposium on System Theory, 2002
Details of a computer model of an eddy-current brake for application in an exercise device are described. In particular, the design of a computer analysis package (EBRAKE) which calculates disk torque as a function of disk speed, for a given system geometry and coil current is reported.

Eddy Currents Electromagnetic Brake Device

IEEE Latin America Transactions, 2016
Brakes are devices most used in industry and transport to control speed. Devices using the electromagnetic field generated by a source to exert torque, reducing speed on mobile devices are called electromagnetic brakes. This paper presents the design stages, development and testing of an electromagnetic brake by the action of currents induced aiming ...

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.

Modeling and Control of Eddy Current Brake

IFAC Proceedings Volumes, 1995
A great deal of attention has been given to numerical algorithms for identification and control of nonlinear systems. The purpose of this paper is the application of some existing techniques for the modeling and regulation of an eddy current brake process.

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.

Physical Mechanism of Eddy Current Demagnetizing Effect for Eddy Current Brake

Journal 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 ...

Linear eddy current brake for railway vehicles using dynamic braking

2008 18th International Conference on Electrical Machines, 2008
One type of braking system for railway vehicles is the eddy current brake. Because this type of brake has the problem of rail heating, it has not been put to practical use in Japan. Therefore we proposed using a linear induction motor (LIM) for dynamic braking in eddy current brake systems.

Experiments with eddy currents: the eddy current brake

European Journal of Physics, 2004
A 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
