Abstract :

Now a day, the demand of renewable energy is dramatically increased. This paper presents a new vibration-based electromagnetic power generator which can convert ambient vibration energy into electric power. A low frequency driven electromagnetic energy harvester (EMEH) consists of a flexural spring, NdFeB permanent magnets, and a copper coil. As the device is excited by the vibration, the construction of the mechanism produces an oscillation of the magnetic circuit with permanent magnets against the fixed coil. Due to Faraday’s law the oscillation movement of magnetic field induces voltage in the coil. The amplitude of the excited oscillation movement depends on level of the vibration and parameters of the mechanism design. Mathematical modeling and ANSYS finite element analysis (FEA) were used to theoretically investigate the mechanical properties of the spring mass system. The proposed EMEH generates a maximum power of 17.46 mW at a resonance frequency of 11 Hz.
