Study of Two- and Four- Spring Electromagnetic Harvesters

摘要

The paper presents a study of two- and four- spring electromagnetic harvesters, consisting of П-shaped plates with 4 magnets mounted on two or four springs, rigidly fixed at their low ends. A coil is placed between the magnets. Modeling by means of ANSYS has been performed and the horizontal deviation of the mechanical system has been obtained. The magnetic fields of the electromagnetic harvesters have been modeled by means of FEMM. Their electromotive forces (e.m.f.) and power have been defined. Experiments for validating the models have been conducted.
