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.

This paper studies the output electrical parameters of a linear generator with permanent magnets without an iron core for three types of electrical connection of its windings. Software simulations have been performed by means of ANSYS 2019 R1 and FEMM, and experimental studies of the linear generator have been carried out. A model has been obtained, which simulates the operation of the generator under study with good level of precision. The optimal scheme of connecting the generator windings, which is suitable for practical realization, has been determined.
