Surge Characteristics of Propulsion Coils Including Mutual Coupling for Maglev

Abstract

The Maglev system employs a linear synchronous motor (LSM) with the primary side on the ground, and uses a combined levitation-guidance system and double-layered propulsion coils. To analyze electric surge propagation, we measured the surge propagation between propulsion coils. We also set up simulation models and simulated the surge propagation by using the Electro-Magnetic Transients Program (EMTP). It was found that the measured values agreed well with the values simulated by EMTP. Therefore, it was verified that the proposed surge propagation models for simulation were very useful to estimate the surge propagation of coils used for Maglev.
