Design of High Temperature Six-Phase Starter-Generator Embedded in Aerospace Engine

This paper examines the problem of the installation of the electric machine to the high pressure shaft to increase the electrification of aircraft engines and create More Electrical Engine. Different ways of synchronous generator integration in the aircraft engine by worldwide aircraft engines manufacturers was discussed. A new design of the high temperature synchronous generator mounted on high pressure shaft is proposed. To evaluate the effectiveness of synchronous generator the electromagnetic, thermal and mechanical calculations are made. High temperature synchronous generator cooling system was designed and system of mechanical decoupling of the stator at short circuits is proposed.
