Abstract
In this paper, a simple and stable generator with high-Tc superconducting levitation is presented in terms of vibration. This system has new methods in levitation, generator, damper and emergency brake. In order to have stable levitation, a superconductor and a permanent magnet are used, and 3 permanent magnets support the top of the shaft. In the part of generator, 8-pole permanent magnet and 8 coils are used to avoid resonance frequencies accordance of self-excited vibration and Lorenz forces. 4-pole permanent magnet and 4 coils are used as magnetic damper. This damper has braking force by the change of the magnetic flux density at the coils.
