Design of A Brushless Doub ly-Fed Machine for Aviation Turboelectric Distributed Propulsion

This paper proposes a high-speed brushless doubly-fed machine for aviation turboelectric distributed propulsion. The electromagnetic performance of the designed machine, including power ratio, voltage capability, power factor, and efficiency is analyzed. A customized rotor mechanical design is introduced, which allows for 4 times increase in speed than legacy designs. A simple TeDP system with one generator and one motor is simulated using FEA-circuit co-simulation in certain operating conditions. The losses and efficiency of the system are investigated for a better understanding of the machine.
