Study on Miniaturization and Weight Reduction for the Application of LIM-type Eddy-current Rail Brakes to High-speed Trains

抄録

To 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.
