MODELING AND SIMULATION OF A SUPERCONDUCTIVE LINEAR MOTOR

摘要

Recent work and advances have showed great development in the field of linear motors, one being the integration of superconductors with the design and implementation of linear motors. In this approach, instead of using the traditional metallic conductors for the motor stator and rotor (to create the electromagnetic core), it was proposed, that the use of superconductor wires would yield greater and more efficient motors. One of the advantages of having perfect conductivity is stronger and more consistent magnetic field for the motor, allowing by that greater transitional speeds. However, until now, there have been no reported designs that could be used in real-world applications. This work is based on an existing design. However, we create a design model of functional linear induction motor using high temperature superconductor wires for the magnetic core. Moreover, a comparison is made between the actual performance specifications (core current, magnetic flux, and magnetic force), with those obtained from experimental simulation methods (using ANSYS Electromagnetic suit or COMSOL Multiphysics software packages). The design model is tested to verify the simulation results, and its suitability for engineering applications.
