Szukana fraza: [Abstrakt = "In paper an electromagnetic energy harvester with two stationary permanent magnets fixed to casing and one movable PM inside is presented. The external force attached to the system causing displacements of the internal magnet, and thus the flux linkage changing in coil wounded on housing is received. In order to obtain the resonance frequency equal 25 Hz, the dimensions optimization was carried out. The results of measurements agree very well with the simulated frequency characteristics."]
