The Design and Performance Evaluation of Position Detection System for Super Speed Maglev

초록

To maximize the propulsion efficiency of 500km/h super speed maglev which is propelled by linear synchronous motor(LSM), precise position of train should be detected and the synchronized current by using position information is provided to the LSM coil installed in guideway. Basically, position detection system should have enough resolution and detecting range with target speed. Specifically, rotection performance against environmental problem, reliability and convenience in setting up are also important factors for design and manufacturing. In this study,regarding 4 types of position detection system, main feature is reviewed and by evaluating the performance, the feasibility of each type is examined.
