A magnetic brake with a solid iron cylinder rotating at high speeds is considered. The rotor iron is both conductive and permeable. The magnetisation curve is non‐linear. Special attention is paid to the correct integration of the angular velocity term. A Newton‐Raphson scheme dealing with the non‐linear material characteristics is applied. The numerical oscillations appearing in the finite element model at high velocities are overcome by an adaptive mesh refinement technique combined with the…
