This paper presents a preliminary model for the study of the electrostatic field repartition in a plane sample of a polymer nanocomposite. The computations were carried out using FLUX3D software package by considering a filler made of spherical nanoparticles uniformly distributed in the polymer matrix. Different combinations of values for the electric permittivity of the polymer matrix and of the nanoparticles were analyzed.

This paper deals with a comparative numerical analysis of performances of several design solutions of induction machines with improved energy efficiency. Starting from a typical cast aluminum cage induction machine this study highlights the benefit of replacing the classical cast aluminum cage with a cast copper cage in the manufacture of future generation of high efficiency induction machines used as motors or generators. Then the advantage of replacement

This paper deals with the finite element based optimal design of a wind energy based heater. The proposed device ensures the conversion of the wind kinetic energy into heat by means of Joule effect of eddy currents induced in the wall of a tubular stator due to the rotating magnetic field produced by rotor permanent magnets. The transient electromagnetic field problem associated to the operation of the device is solved using a 2D finite element approach

This paper deals with the numerical modeling of the electromagnetic field in transverse flux induction heating devices and with features of forces due to non-symmetrical position of the sheet to be heated within the inductor air-gap. The results of four field computation models are compared. Three computation methods of the electromagnetic force acting on non-magnetic and magnetic sheets are used. The influence of the horizontal and vertical sheet
