ELECTROMAGNETIC VIBRATORY GENERATOR FOR LOW FREQENCY VIBRATIONS
HADAŠ, Z. ONDRŮŠEK, Č. SINGULE, V. FIALA, P.
Electromagnetic vibration generator for generation of electric energy comprising a movable member (2) member (9) arranged to the frame (1), an excitation circuit (8) attached to the movable member (2) and a coil (7), while the coil (7) and the excitation circuit (8) are movably arranged one towards the other in a way so that the magnetic field of permanent magnet (83) is capable to induce voltage in the coil (7), wherein the flexible member (9) is formed of fixed permanent magnets (4) attached in the frame (1) and of one or more movable permanent magnets (3) attached to the movable member (2) with the excitation circuit (8) provided with the hinge (6) mounted in the case (5), while the excitation circuit (8) is formed of at least one permanent magnet (83) arranged on at least one pole piece (81), for creation of magnetic flux through the coil (7), at the same time the coil (1) is in static manner arranged on the frame (1) toward the excitation circuit (8), around which this moves transversably or vice versa.
