Abstract
- Two-dimensional (2D) finite element models of electrical machines are known to over predict iron losses when modeling systems excited using pulse width modulation. This digest presents the integration of a simple first order 1D approximation of the eddy current distribution within the lamination into a 2D finite element model. Simulations of an induction machine under no-load conditions using standard 2D FEA methods and the proposed method are compared with test measurements. The proposed approach is shown to improve the accuracy of the predictions while reducing simulation time. [ABSTRACT FROM PUBLISHER]
