Analysis and Optimization for Winding Topology of Multiphase High Power DC Generator in Future Hybrid Electric Propulsion Aircraft

High power Wound Rotor Synchronous Machine (WRSM) is expected to be a candidate for generators in future hybrid electric propulsion aircraft. Multiphase armature winding is an effective way to achieve high power electric machine. The winding topologies of multiphase DC generator based on WRSM are various. Different winding topologies determine different performance of the generator. So it’s critical to design and select suitable winding topology. In order to illustrate the uniqueness and optimality of the winding topology, this paper analyzes and compares the winding MMF, winding utilization and output power of different winding topologies of the 8pole-96slot 600kW WRSM.
