The trend to improve efficiency, safety, and
reliability as part of more-electric-aircraft initiatives is mediating the
rapid development of aerospace systems. In addition, the increasing need for
leadership in the socio-military-economic area brings the focus of studies on
unmanned aerial vehicles in aviation. However, developments in power
electronics and control algorithms, permanent magnets, high-speed transmission
elements, and iron core material technologies reveal the need for using
Starter/Generator structures in hybrid propulsion systems. This paper explores
the optimum design of an In-runner Synchronous Permanent Magnet
Starter/Generator with specifications of 1 kW-4500 rpm for motor mode and 1.25
kW-5500 rpm for generator mode, especially for small UAVs equipped with a
piston engine. Thus, charging the battery packs and the required thrust can be
provided with higher efficiency. The preliminary dimensions are obtained
analytically. The design issues of materials and topologies are discussed. The
novel model is optimised in Ansys Maxwell 2D based on finite element analyses.
Dynamic and static simulations are performed with the optimetric sensitivity
method, and the efficiency study is carried out in Maxwell 3D. The margin of
difference between the analytical and numerical results is calculated
comparatively.
