Abstract
On the wheel-rail supported hybrid railway system, LSM for Very High Speed Transit must be a system that can maintain a large airgap, and the maximum vertical displacement must be taken into consideration in designing the LSM. As such, this paper designs two small-scale LSM models that produce equal output power, one with the normal-conducting magnet and one with the superconducting magnet. In addition, this paper conducts a comparative analysis of the various characteristics by applying the electromagnetic numerical analysis method. Furthermore, the study manufactures two small-scale LSM prototypes which have the normal-conducting magnet and the superconducting magnet, while also conducting no-load and load test. Through such comparisons, this study attempts to verify the characteristic values of the two models.
