A Comparative Study of Three Starting Strategies for an Aero Flywheel Motor Using the Modified DTC Method

IEEE Access, 2019
An aero flywheel motor (AFM) is an integration of a starter, generator, and inertial flywheel on the traditional aero piston-engine (APE). When performing as a starter, the AFM is responsible for dragging the APE to a high speed (600-800 rpm) in a short ...
