An eddy current braking system
1993 (25th) Southeastern Symposium on System Theory, 2002Details 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.

Analysis of an Eddy-Current Brake
IEEE Transactions on Power Apparatus and Systems, 1965The retarding torque of an eddy-current brake is calculated as function of the angular velocity of the rotor and of the stator dc magnetizing current. The electromagnetic field components are found in the rotor medium by solving the field equations. Integration of the power flow vector E X H over the rotor surface yields the total retarding power of ...

Optimal robust control of a contactless brake system using an eddy current
Mechatronics, 1999 As vehicle speed increases, a more powerful brake system is required to ensure vehicle safety and its reliability. A contactless eddy current brake (ECB) is developed to take the superior advantages of fast anti-lock braking to the conventional hydraulic

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

THE DESIGN OF EDDY-CURRENT MAGNET BRAKES
Transactions of the Canadian Society for Mechanical Engineering, 2011The eddy-current is created by the relative motion between a magnet and a metal (or alloy) conductor. The current induces the reverse magnetic field and results in the deceleration of motion. The proposed mechanism implements this phenomenon in developing a braking system.

Eddy Currents Electromagnetic Brake Device
IEEE Latin America Transactions, 2016Brakes 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 ...

A laboratory activity on the eddy current brake
European Journal of Physics, 2012The aim of this paper is to introduce a simple and low-cost experimental setup that can be used to study the eddy current brake, which considers the motion of a sliding magnet on an inclined conducting plane in terms of basic physical principles. We present a set of quantitative experiments performed to study the influence of the geometrical and ...

An Antilock-Braking Algorithm for an Eddy-Current-Based Brake-By-Wire System
IEEE Transactions on Vehicular Technology, 2007This paper presents a nonlinear sliding-mode-type controller for slip regulation in a braking event for an electromagnetic brake-by-wire (BBW)-system-equipped automobile. The electromagnetic BBW system under consideration consists of a set of eddy current brakes (ECBs) attached to the automobile wheels.
