This paper is a summary of the IEEE P1812, a working group devoted to developing a testing guide for permanent magnet (PM) machines. This guide is intended to cover a broad range of machines, encompassing all voltage levels, power ranges, frame sizes, and applications. This paper will serve to inform the interested entities: users, manufacturers, government and private laboratories, military, and...
Electric drive systems, which include electric machines and power electronics, are a key enabling technology for advanced vehicle propulsion systems that reduce the petroleum dependence of the ground transportation sector. To have significant effect, electric drive technologies must be economical in terms of cost, weight, and size while meeting performance and reliability expectations. This paper...
Solar powered aircraft require electric drives for the main propulsion system. It is critical that these drives provide both very high efficiency and low mass. This paper describes a permanent magnet machine drive, developed specifically for this application. The machine uses 6% silicon steel laminations to achieve very low iron loss, combined with a high pole number to minimize mass. The system has...
