Electric Machines with High Specific Power

Abstract Specific power, defined as the ratio of output power to total mass, is one generally accepted figures merit for electrical machines. Given growing interest in electric aircraft, developers are trying demonstrate a high value this indicator their products. This paper provides an overview projects machines with density, use which promising aircraft various dimensions. Projects University Nottingham, Illinois, Siemens, Yasa, and others were considered. An analysis technical technological characteristics approaches design, manufacturing, testing given.
