Feasibility of Wheel-Based Magnetostrictive Energy Harvester

摘要

This paper presents the feasibility of a wheel-based magnetostrictive energy harvester (MEH), which consists of one coil-wound Galfenol cantilever with two PMs adhered onto the each end, and one PM array sandwitched between two wheels. Simulation is used to validate the concept. The proof-of-concpet MEH is fabricated by using the simulation results, and subjected to the experimental characterization. Two experimental setups are used to study the feasibility of wheel-based MEH: one with magnetostrictive acuator, and the other with the motordriven PM array. It can be concluded that Generated voltage peaks near resonance of the cantilever and increases with rpm and with number of coil-turns. Future work includes optimization of wheel-based MEH performance via PM array configuration, and development of protptype.
