A Comparison of the Loss Characteristics in Induction Motors with the Different Core Materials

This paper intends to study the loss characteristics of the induction motors with the different core materials, in which the flux density distribution at the local core positions, including the fundamental and harmonic components, are computed and analyzed by Time-Stepping Finite Element Method (T-S FEM), then the influences of the different core materials on stator and rotor copper losses, as well as, iron losses are further studied.
