Overview

Randomized trial shows improved computational efficiency in modeling electromagnetic properties, suggesting practical applications in electric motors.

Key Points

  • This work aims to create a surrogate model that streamlines the simulation of electromagnetic properties in electric motors.
  • Developed a Fourier coefficients-based surrogate model for motional voltage vector and inductance matrix.
  • Assessed surrogate accuracy by varying the number of sampling points, with a focus on a 500-point sampling.
  • Applied the surrogate model within an ODE-based simulation to compute circulating currents.
  • The 500-point surrogate model closely matched FEA evaluations for motional voltage and inductance.
  • The method significantly reduced computational time for simulations needing extensive FEA evaluations.
  • Surrogate modeling is effective when applied to periodic mechanical orbits, ensuring converged solutions.
