Design of electromagnetic field of permanent magnet generator for VTOL series-hybrid UAV

Series hybrid Unmanned aerial vehicle(UAV) that is proposed in this paper performs Vertical take-off and landing(VTOL) using the battery and generator, and it applies the series hybrid system with combination of the small engine and generator when cruising flight. This system can be described as the next-generation system that can dramatically increase the UAV flight times. Also, UAV systems require a large energy at the time of VTOL to be conducted for a short time. Therefore, this paper designs Permanent Magnet Synchronous Generator (PMSG) having a high specific power considering VTOL through the FEA.
