Halbach Array Arrangement of Magnets for Energy Harvesting by Vibration

C. N. Divya | C. Praveen Kumar

Abstract: The electromagnetic transducer is in current scenario, received a paramount importance in harvesting the energy dissipated due to vibration in macro scale. This developed work is developed in the motive of harvesting the energy from vibration using an improved Halbach array. It is a specific arrangement of permanent magnets that concentrates the magnetic fields on one side of array while cancelling the field the other side to almost zero. The output power of harvester with Halbach array is found to be less than those with normal magnet layouts. This energy harvest system developed an improved Halbach array. The simulation results show that the output power of the improved energy harvester has increased by a factor of 1.5 when compared to normal configuration. The frequency response of normal magnet and improved Halbach array is compared using LabVIEW software.
