Abstract :
A 3-dimensional (3D) transient finite element analysis (FEA) approach taking into account the effects of steel lamination core loss is proposed. When using the T-Omega method, the effects of lamination core loss are considered by introducing an additional field component in lamination regions which is derived from the instantaneous core loss in the time domain. The proposed approach is validated in two applications by the power-balance testing, that is, the input power increase due to the core-loss effects must be equal to the total core loss.
