Abstract
This study introduces a novel methodology based on an extensive mathematical analysis, performed from basic electromagnetic principles, with an optimized cost for a magnetic levitation Hyperloop system. This new approach uses both permanent magnets and electromagnets to levitate, propel, and control a pod. The electrodynamic suspension system is emulated as a small pod attached with permanent magnets from the bottom, which resembles a short-rotor linear synchronous motor. A comprehensive finite-element analysis using ANSOFT Maxwell software on the effects of the magnetic field distribution of the coils due to the ac current flowing through them is investigated. The effects of the magnetic force exerted on the permanent magnet secondary are examined as well. The whole magnetic levitation system prototype was implemented in the laboratory as a proof of concept in order to validate and verify the simulation results. The simulation results are in full agreement with the mathematical analysis, which assures the validity of the design procedure and the magnetic analysis.
