Abstract
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 been developed to maximize efficiency, taking into account both power electronic and motor losses.
