Design and modeling of a five-phase aircraft synchronous generator with high power density
This paper presents a methodology for the design and modeling of a five-phase aircraft synchronous generator with high-power density. A new method was recently proposed for a more accurate model of the air-gap of a salient pole rotor through expanding the inverse of an effective air-gap function for three-phase synchronous generators. This approach is adapted to the five-phase case here, with some modifications to the derivations. Five-phase decoupling direct-quadrature theory is reviewed and presented as the basis for linear modeling of the five-phase synchronous machine. Following the procedure for a three-phase design with five-phase considerations, a 200 kVA high power density synchronous generator with 12 krpm rotational velocity is obtained. Finally, the design is verified using finite element method software
