Effects of Rotor Material on Eddy Current Brake Performance
European Mechanical Science, 2017 The eddycurrent brake(ECB) is built by corresponding motion between a coil and a metallicmaterial. The eddy current and coil creates reverse magnetic fields w producesbraking force and dissipated heat due to resistivity of rotor material.

Design considerations of high-speed eddy-current brake [PDF]
Archives of Electrical Engineering, 2014 Abstract The paper presents results of analysis of the influence of rotor construction on the steady-state torque-speed characteristics of a high-speed eddy-current brake. The investigation is carried out using two- and three-dimensional finite element models and measurements. A series of computations is carried out in order to find out the method
