Design possibilities of multiple-pole cylindrical rotor synchronous machine excitation winding

This article provides design and finite element analyses information of two possibilities of cylindrical rotor synchronous machine excitation winding designs. It is focused especially on multiple-pole synchronous machines, where the presence of higher amount of machine poles reduces amount of available slots for excitation winding, therefore all negative effects are well observable. On these topologies a comparison of design results is accomplished. The comparison includes traditional topology of excitation winding and sine-wave current volume excitation.
