In this work, we present a methodology for the design and analysis of a double-sided linear induction motor for a scaled Hyperloop pod in COMSOL Multiphysics®. The key aspects are discussed as follows:

  1. Formulation of problem and simulation environment: The goal is to design a Double sided linear induction motor that will propel a scaled hyperloop pod up to a target speed of 100 m/s. The physics environment, study settings, and results visualization and validation will be presented.
  2. Thermal analysis of the primary (mounted on the pod) and secondary (the I-beam) using Multiphysics environment.
  3. Optimization of design using cluster computing: The design involves the understanding of most significant parameters and sweeping over the constrained range for each of them.
  4. Analysis of the performance using control signals from MATLAB®. To study the effect of non-ideal sinusoidal voltages on the performance of the DSLIM, LiveLink™ for MATLAB® is used to feed the modulated voltages. Then the post-processing of output force and current are used to analyze the effect of harmonics on the DSLIM.
