We have developed a non-contact power supply system for railway vehicle. A figure-of-eight coil which is able to decrease the leakage flux was adopted as a coil configuration. In this work, a proto-type system has been developed and its power collection performance was evaluated by using a test vehicle.

Takashi SASAKAWA Maglev Systems Technology DivisionTo apply LIM-type eddy-current rail brakes to high-speed trains, it is necessary to miniaturize and reduce the weight of their armature mounted on bogies. This paper therefore considers reducing the volume of the iron core, taking into account the need to maintain braking performance at high speed, which has a great effect on braking distance. Electromagnetic field analysis was then used to verify the braking performance of the miniaturized armature by comparing it with armatures developed to perform well at low speed.
