Maglev Starting of Controlled-PM LSM Maglev Carrier with Lateral Motion, Using 3D-FEA-Interpolation

Abstract

Maglev starting of the controlled-PM (Permanent-Magnet) LSM (Linear Synchronous Motor) Maglev carrier which has five degrees of freedom exclusive of propulsion motion is investigated theoretically and experimentally. The 3D-FEA (Finite Element Analysis) interpolation is proposed for including that lateral force related with sway and yawing motions which is obtained numerically by 3D-FEA. In vehicle dynamics simulation with Maglev starting, the method is of practical use for calculating 3-dimensional forces of thrust, lift and lateral ones, with extremely small CPU time. The modelling is verified experimentally under an integrated robust-control of Maglev starting of the carrier with lateral-motion.
