• Resumen

  • The paper describes an efficient method to extract the B-H nonlinear characteristic from the experimental flux-current  ÿ I data obtained using a non-uniform magnetic field device. Both functions are monotonically piecewise linear approximated with the same number of breakpoints. The method was successfully applied to characterize the ribbon core material of a fluxset magnetic field sector. In this case the hysteresis loop and the lumped magnetic circuit were extracted. Comparison with experimental results validates the proposed method
