Analysis fund Comparison Of The Linear Eddy-Current brake systems

The development of linear Eddy-Current brake systems has gradually gone beyond the adhesion limit in high-speed vehicles. In particular, the practicality of using permanent magnet in Eddy-Current brake systems is obviously recent, due to the manifold improvement in magnet materials and technology. On the basis of analytical two-dimensional field solution, this paper deals with flux density and force calculation about the linear Eddy-Current brake systems: DC excited electromagnet, Halbach magnetized and vertical magnetized permanent magnet.
