| Abstract |
We have studied electromagnetic and electromechanical problems of superconducting linear drives by numerical simulations and experiments. We have taken two applications: A superconducting magnetically levitated vehicle and a small superconducting linear actuator. From the numerical analysis on the superconducting magnet of the EDS-LSM Maglev vehicles, we have found that the dynamic coupling of electromagnetic and mechanical vibrations causes the enhancement of the eddy current loss in the cryostat around the mechanical resonance frequency, and the rigidity or elasticity of the support structure seriously affects the electromagnetic phenomenon in the magnet. As for the high-Tc superconducting linear actuator, we have succeeded in making a reciprocating motion of a mover by controlling the frequency of primary winding current, and obtained the basic running characteristics. |
