The project ELAPSED at the University of the Bundeswehr Munich investigates and develops electrical drivetrains and concepts for General Aviation. In this paper, the design of an electrical motor for Light Sport Aeroplanes (up to 600 kg takeoff weight) is discussed. Starting with the equations of motion and a propeller model, the requirements for the motor are derived from first principles. The typical design process of an e-motor is then described beginning with basic considerations about the size of the motor and key electromagnetic quantities. A stator with a concentrated winding and flux barriers, one of the main attributes of our design, is introduced. Finally, the motor is optimized to produce an efficient and light design for which the efficiency in the planes operating points is calculated. This paper aims to provide a multi-disciplinary approach to aircraft e-motor design, illustrate the source of the motor requirements, as well as, the motor design so that aircraft engineers and e-motor designers can better cooperate.
