Hyperloop Transportation System: Control, and Drive System Design

This paper presents a novel methodology on the design and analysis, performed from basic principles, with an optimized cost for a magnetic levitation Hyperloop system. It uses permanent magnets and electromagnets to levitate, propel, and control a pod. A comprehensive investigation with the help of a detailed finite element analysis on the effects of the magnetic field distribution, due to the alternating current being applied to the propulsion and levitation system, was provided. Simulations from ANSOFT Maxwell are given. A short-rotor linear synchronous motor (LSM) was designed as a small pod with permanent magnets at the bottom to emulate the electrodynamic suspension system. Furthermore, the effects of the magnetic field force, exerted on the permanent magnet rotor, were also examined. The whole magnetic levitation system prototype was implemented experimentally, as a proof of concept prototype, in order to verify the simulation results. The results are given to assure the validity of the magnetic analysis, design procedure, simulation results, and experimental results.
