Mechanisch-magnetischer Nullsteifigkeitsmechanismus und Energieharvester

The device (10) has a magnetic field generator (18,22) that generates a magnetic field, so that magnetic force (Fm) originated from magnetic field on movable region (14) is worked against a spring force (Ff) over a deflection interval (26). Boundary surfaces (24a,24b) of magnetic field generator are provided for facing the boundary surface of movable region. The boundary surface of magnetic field generator is separated from the boundary surface of movable region by a gap (20), such that the boundary surfaces are not in coplanar manner. USE: Device for converting kinetic energy into electrical energy, used in vibration-decoupled bearing (claimed). ADVANTAGE: Since the boundary surface of magnetic field generator is separated from the boundary surface of movable region by a gap, the efficiency of energy harvester is increased. The resonant frequency of device is reduced. The drawing shows a schematic view of the device for converting kinetic energy into electrical energy. 10 : Device for converting kinetic energy into electrical energy 14 : Movable region 18,22 : Magnetic field generator 20 : Gap 24a,24b : Boundary surfaces of magnetic field generator 26 : Deflection interval Ff : Spring force Fm : Magnetic force.
