Magnetic induction hovertrain - with orthogonal superconducting coils to induce eddy currents for minimum magnetic drag

摘要

The magnetic induction hover train has two sets of superconducting coils (8, 9) which induced eddy currents in a non magnetic support track (10) between the coils. In order to minimise the magnetic drag without using a complicated null-flow circuit, the two sets of coils are positioned with their axes at right angles to each other. One of the sets of coils can be used as part of a linear induction drive which results in considerable weight saving. The drive for the train is by a linear synchronous motor. The system is intended for speeds in excess of 400 km/h.
