Efficient magnetodynamic lamination model for two-dimensional field simulation of rotating electrical machines

Abstract This article presents a 2D–1D time-stepping finite-element model to evaluate the magnetodynamic rotational hysteresis effects in an electrical machine laminated cores. The 1D model is at first validated separately and then incorporated into the 2D model using an efficient iterative fixed-point procedure. A viscosity-based hysteresis model is applied in the lamination to account for the dynamic losses while the rotational field quantities are handled by a modified inverted vector hysteresis model. The 2D–1D model is evaluated by computing the core losses of an induction motor and experimental data of the motor are used for verification.
