AbstractA transition from a centralized, hydraulically based power source to a multi-source electric power base is eliciting a need for an electrically powered aircraft. This electrical power base will be composed on multiple, independently operated electric units, working together to power the craft. A premeditated obstacle to this innovative approach is achieving a level of power density that will meet weight and volume criteria in aircraft application. High power density electrical machines innately present thermal management issues. These issues stem from condensed power dissipation in a smaller volume and surface area. The temperatures associated with this application demand attention in the motor design and selection of materials that will meet life requirements of an application. SatCon Applied Technology proposes to meet these challenges by developing a motor with high power density, magnet and insulation systems that withstands the aircraft high temperature environment. A feasibility study of permanent magnet formulation, temperature sensitivity, and affecting environmental variables will be conducted. The end result will be a comprehensive understanding of long life insulation systems capable of withstanding high temperatures in a compact motor design. Cooling methods appropriate to manage temperatures in the aircraft will be evaluated and the most appropriate solution implemented.
