MICROSCALE, AXIAL-FLUX, PERMANENT MAGNET GENERATOR Florian Herrault, Chang-Hyeon Ji, Seong-Hyok Kim and Mark G. Allen Microscale, axial-flux, PM generators are an active area of research for high power density electromechanical energy conversion. These devices are of particular interest because their planar geometry merges well with MEMS fabrication techniques. These electrical power converters require input mechanical power, and hence rely on power from an integrated turbine or some other mechanical power source, such as a gas-fueled turbine engine. Axial-Flux Permanent Magnet Machine Close-up on the stator We demonstrated 16 W of mechanical-to-electrical power conversion and delivery of 8 W of DC power to a resistive load at a rotational speed of 305 krpm. (59 W/cm^3power density). Sponsors: Army Research Laboratory Collaborative Technology Alliance (DAAD19-01-2-0010). Other projects: Ultraminiaturized, Permanent Magnet Generators à
