Study of four-spring electromagnetic harvesters

Abstract

The article considers electromagnetic harvesters, consisting of a metal plate, fixed on four springs at their lower end, and having 2 or 4 magnets. A coil is located above the magnets. Modeling by ANSYS has been done, and the horizontal deviation of the mechanical system has been obtained. With the help of FEMM, the magnetic field of the electromagnetic harvesters has been modeled and their electromotive force has been determined. Experimental studies have been performed to verify the modeling. The influence of the construction parameters on the output electric features of the studied harvesters has been considered.
