초고속 자기부상열차용 LSM 설계 및 추력 측정 시험

초록

This paper deals with design and thrust force measurement of EMS type LSM for propulsion of thehigh-speed maglev train. The load of maglev train is calculated, and the design equations of the LSM are presented, andthe LSM which is suitable for the operation of short-distance test track is designed. In addition, the finite elementanalysis is performed to confirm the back-EMF and thrust force characteristics of the LSM designed model. A shortlength LSM prototype model is manufactured. Finally, the thrust force of the LSM is measured by the method applyingdc current to the stator winding instead of three-phase ac current. And the validity of the design and analysis is verifiedby this measurement.
