An electromagnetic model is proposed to compute translational motion eddy currents in a conductive plate. The eddy currents are due to the movement of the plate in a dc magnetic field created by a permanent magnet (PM) inductor. First, the magnetic field, due to the PMs, is computed in three dimensions, where the iron yokes’ influence is considered because of the method of images. Then, the motional...
This paper deals with the 2D analytical solutions of the magneto-thermal equations in the case of the aluminum plates heated by an AC three phase transverse flux inductor. In the topology of transverse flux induction heating (TFIH) considered in this work, the conductive plate is subjected to linear movement with constant speed inside the inductor. The magneto-dynamic problem is first solved, by using...
In this paper, a finite element modelling of permanent magnet micro actuator is presented. The later is coupled with a micro screw pump, which can be used in biomedical applications for the pumping of biological fluids such as blood (surgery of heart, blood treatment machines). The resolution of the electromagnetic problem is carried out in 2D magnetostatic assumption in Cartesian case. The characteristics...
