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 motor-driven 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.
