Electromagnetic brake with controllable torque
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1961MANY LARGE materials handling machines and processing machines require smooth, accurate stopping. In the past, accurate stopping has usually been accomplished by the use of hydraulic brakes. Recently, an electromagnetic brake has been developed to perform the same functions and to overcome some disadvantages of hydraulic brakes, such as the need for ...

Electromagnetic braking of a metallic projectile in flight
IEEE Transactions on Magnetics, 1985A simple model for the electromagnetic deceleration of a moving metallic projectile is described. It incorporates the influence of magnetic field parameters, time-dependent field diffusion, and device geometry on braking action, albeit in an approximate fashion. The model predicts that a viable experimental braking device can be designed.

Diagnostics of Electromagnetic Friction Brakes and Clutches
2019 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2019This paper proposes and theorizes upon a new method for diagnosing movable-armature electromagnetic mechanisms (EM), which is based on an additional high-frequency electric-field effect on the EM magnetic core; the field excites corresponding high-frequency electrodynamic processes that are not related to the EM operating parameters and do not affect ...

Design and Analysis of a Regenerative Electromagnetic Brake
IEEE Transactions on Magnetics, 2014In this paper, a regenerative electromagnetic brake, which has the same structure as conventional electromagnetic brakes and the same principle as self-excited induction generators, is introduced, and a miniature model is designed. The most important part of the design stage is to choose proper equivalent circuit parameters for self-excitation within a

Finite element analysis of an electromagnetic brake
IEEE Transactions on Magnetics, 1983The paper presents an analysis of the distribution of the magnetic flux in an eddy current braking device. The analysis is based on a non linear finite element computation of the magnetic field combined with an analytical or numerical evaluation of the eddy distribution in the conducting slab.

Anti-Lock Braking Control of an Electromagnetic Brake-by-Wire System
Dynamic Systems and Control, Parts A and B, 2005This paper presents a nonlinear sliding mode type controller for slip regulation in a braking event for an electromagnetic brake-by-wire system equipped automobile. The electromagnetic brake -by-wire system under consideration consists of a set of eddy current brakes attached to the automobile wheels. The anti-lock braking controller modifies the brake

Optimal Control of Electromagnetic Brake Retarders
SAE Technical Paper Series, 1994<div class="htmlview paragraph">An electromagnetic brake retarder is a device for assisting the brakes of heavy vehicles during descents down long steep inclines. As it operates, a brake retarder heats up and this causes its performance to deteriorate.
