Abstract :
We apply a linear Halbach magnetized mover to an eddy-current braking system for high speed railway applications. On the basis of analytical two-dimensional field solutions considering end effects, this paper deals with the magnetic field, eddy current distribution, forces according to the secondary relative permeability, and conductivity. We also present comparisons between analytical results and experimental data.
