Rolling Magnet Energy Harvester

This thesis investigates the concept of a Rolling Magnet Energy Harvester (RMEH), a kinetic energy harvester based on the principles of electromagnetic induction. Designed with shipping containers in mind, the RMEH harnesses energy from the rolling motion of ships to power potential onboard sensors. The objective is to enhance logistics by providing a simple, sustainable, and maintenance free energy source. The thesis aims to verify the RMEH concept and identify optimal design parameters. This is accomplished through the development of a comprehensive model. The model analyzes ship data to simulate the rolling motion at sea, which is used to simulate the dynamics of the rolling magnet. Power data is estimated and used with power electronic simulations. Experimental testing successfully proves the concept of the Rolling Magnet Energy Harvester.
