Design Considerations of 400-Cycle Aircraft Motors

SEVERAL papers have been presented describing the reason for the selection of 400-cycle three-phase service for motors aboard aircraft. In view of the fact that the decision has been made to use 400 cycles, the purpose of this paper is to present some of the motor-design problems to the men who must write the specifications for these motors. A better general understanding of the performance to be expected from 400-cycle induction motors will help both the aircraft electrical engineer and the motor designer.
