Abstract
In the superconducting maglev system it is important to develop a non-contact on-board power source without environmental pollution such as noise and exhaust gas. For this purpose many on-board power sources have been studied, such as fuel cells, ram-air turbine generators, and linear generators. We have studied linear generators as the most realistic system.In the combined-type linear generator, much eddy current losses and vibrations occur in the superconducting magnet, because the linear generator coils are attached to the surface of the superconducting magnet. This paper describes the influence of these eddy current losses and vibrations by numerical analyses and measurements of bench tests. It can be considered that there is little effect of load loss in operating the combined type linear generator.
