abstract = {The paper presents a Finite Element Analysis (FEA) based efficient analysis procedure for permanent magnet synchronous motor (PMSM). The study based on finite element models (FEM) offers much more information on the phenomena characterizing the operation of electrical machines than the classical analytical models. This paper attempts to present a dynamic model involving FEA and equivalent circuit simulation together for PWM inverter fed PMSM assisted based on Maxwell 2D and Simplorer. The nonlinear magnetization characteristics have been considered and calculated by FE software Maxwell. The scheme of the inverter are built using the circuit components in Simplorer environment. Based on FEM, the influence of the inter turn fault on the PMSM behavior under various conditions and severity is studied. The comparison of the results obtained by simulation tests allowed verifying the precision of the proposed FEM model. Using the simulated model, this work presents a technical method based on Fast Fourier Transform (FFT) analysis of stator current and electromagnetic torque to detect the faults of inter turn using Simulink/Matlab. The technique used and the obtained results show clearly the possibility of extracting signatures to detect and locate faults. © 2016},

abstract = {We propose a computer-aided design tool of complex passive microwave devices in rectangular waveguide technology by hybridizing the finite element method and a modified multimodal variational formulation. The finite element method characterizes waves in the arbitrarily shaped discontinuities and the total response of the circuit is obtained by applying the modified multimodal variational formulation. The size of the scattering matrix of the total circuit depends only on the number of accessible modes in the beginning and the end of the overall structure. This feature makes the computation time of our hybrid method independent from distances between discontinuities of the circuit. The proposed hybrid method is successfully applied to the full-wave analysis of filters with great practical interest (i.e., multimode filters), thus improving computation time and memory storage against several full-wave finite element method based computer aided design tools. © 2011 IEEE.},
