Patent ID: 11152843

Abstract:
An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising: a central mast, an electrically conductive coil assembly fixedly mounted to the mast, a magnetic core assembly movably mounted to the mast for linear vibrational motion a biasing device mounted between the mast and the magnetic core assembly, the biasing device comprising a pair of first and second plate springs, and a resilient device mounted between the biasing device and the magnetic core assembly, the resilient device being configured to be deformed between the biasing device and the magnetic core assembly when the magnetic core assembly has moved, by the linear vibrational motion, away from an equilibrium position by a predetermined non-zero threshold amplitude, the resilient device comprising a pair of first and second flat spring elements, each having an outer edge fitted to the magnetic core assembly and a free inner edge.
