Abstract: The electromagnetic fields in a fast-rotating ferromagnetic cylinder are
computed using a spectral-element method, considering the heavy saturation
of the surface. The method offers a far better convergence of
the discretisation error compared to the finite-element method. Upwind
techniques for overcoming spurious oscillations and specialised iterative
solvers, as needed for the finite-element formulations, are avoided. The
nonlinear spectral-element formulation allows to simulate the torques and
losses in high-speed induction machines and magnetic bearings up to a
high accuracy with relatively small models.
