Abstract
This paper presents the development of a micro-rotational electromagnetic generator for high speed applications. The generator followed an axial flux permanent magnet design. It was constructed with a rotor composed of multiple permanent magnet poles and a stator made of stacking micro-fabricated planar coils (25mm in diameter and 2mm thick, not considering the casing). The rotor is composed of commercially available NdFeB permanent magnets (6x2x1mm) while the rotor is made of 10 individual copper-clad polyimide layers (18μm thick copper, 25μm thick polyimide). The planar micro-coils were manufactured by photolithography with 100μm line width copper tracks. The rotor was assembled by placing the permanent magnets in a CNC-machined slotted disk. The generator was capable of producing 3.2V and 5.8mW of power at a rotational speed of 4,000rpm. © 2012 IEEE.
