Abstract

This paper deals with the shape design of the iron-core of a hybrid EMS (electro-magnetic suspension) system. A proto-type hybrid EMS system was developed by Yonsei University in 2010 ,. It is the first step of study on fundamental technology for advanced railroad systems development. The hybrid EMS system requires cooling systems because it uses superconducting magnets ,. These cooling systems can influence costs to making and operating the hybrid EMS system. Therefore, a study to reduce the number of cooling systems needs to be carried out in order to economically commercialize the hybrid EMS system. In this paper, a method that reduces the number of cooling systems of the hybrid EMS system was proposed. To achieve this, a small-scale iron-core and coils assembly was fabricated. Using this system, characteristics of levitation force according to the structure of the iron-core was evaluated. Also, numerical analysis using the FEM tool in order to evaluate the levitation force and net force of a full-scale model was performed. This paper can be expected to suggest useful data for the design of a hybrid EMS system.
