The 3-D time-harmonic finite element method (FEM) has been used to calculate forces and deformations of synchronous generator end-windings under nominal operational conditions. Analysis of the time-variant magnetic field has been performed using a T, Phi - Phi formulation. A novel method to consider the rotating magnetic field of the rotor in the frequency domain has been developed. The influence...
The validation of an analytical approach to determine the noise behaviour of induction machines is presented. Analytical electromagnetic, structural and acoustical computations are performed. Data obtained by numerical computations as well as by vibration and noise measurements are compared with the analytical results.
The goal of this paper is to compute k-β diagrams of photonic crystals, accurately and fast. For this purpose, we propose a multi-point model-order reduction scheme for the modal analysis of periodic structures, based on the finite element method. Our numerical example demonstrates that the new approach is significantly faster than conventional FE solutions, while error levels are very similar.
Investigations of the noise behaviour of induction machines demand the calculation of the rotating force waves and thus the determination of the field-harmonics. The goal of this paper is to obtain a method to compute the field harmonics of a skewed induction machine using a multi-slice model.
