PROJECT TITLE :
Optimizing Air-Core Permanent-Magnet-Based Energy Harvest in Free-Rotating Devices
This paper details the analysis and style of an air-core permanent-magnet-based mostly energy-harvest system for use within an in-pipe mobile water-quality sensor. The sensor may be a free-moving/free-rotating device of which the energy-harvest system occupies an appreciable volume. Therefore, the electrical and mechanical dynamics of the device are strongly coupled, that poses a modeling challenge. To deal with this challenge, a rigorous electrical/mechanical model is established to work out expected energy harvest, given the geometric/material parameters and electrical/mechanical inputs. The model was utilised inside one-objective optimization—maximizing energy harvested from impacts—to design a prototype, which was constructed and used for model validation. Subsequently, multiobjective optimizations were performed to determine the tradeoff between energy harvest versus device volume and impact-based mostly versus rolling-based energy-harvest efficacy.
