HOVER BOARD

Abstract

In this project, electromagnetically levitating hoverboard is built. The levitation is made possible by feeding alternating current through a coil, which is placed over aluminium sheet. The coil creates alternating magnetic field when alternating current is fed to it and this magnetic field induces alternating eddy current to the aluminium sheet. Eddy currents create opposing alternating magnetic field and the interaction of magnetic fields produce lifting force. During project, a feasibility study was conducted by researching requirements to produce enough lift for given mass so levitation is achieved. Project also included designing and constructing planar coils, inverter and body for the hoverboard. Design process consisted of drafting schematics and plans as well as selecting components and materials for construction. Hoverboard testing was conducted to validate simulations and designs. Tests consisted of system turn-on tests, full system tests, failure analysis and problem solving. In the short business aspect exercise hoverboard was given product name “HoveBev” from the business idea that hoverboard could be used to levitate beverages. The hoverboard was never fully realized as per to project plan. Project itself was successful as a university project in teaching students practical project work, teamwork and problem solving skills. It also gave practical experience in fields of electromagnetism, power electronics, electronics, power systems and mechanical design.
