These machines offer many potential advan tages over conventional integer slot winding (ISW) machines but suffer fro m a large number of armature magneto-motive force (MMF) harmonics that ind uce excess eddy current losses in the rotor and PMs. Furthermore\, surface -mounted PM (SPM) machines with FSCW have almost no machine saliency\, mak ing them incompatible with sensorless control schemes currently employed i n offshore wind turbines. For FSCW to be an attractive alternative for off shore wind turbine generators\, these downsides must be mitigated.\n\nThis work proposes a novel machine topology that utilises dual multiphase hybr id star-polygonal connected windings to eliminate unwanted MMF harmonics a nd improve machine torque performance and efficiency. In the particular ca se of a 3-phase machine\, machines with a coil pitch of 1 and 2 are propos ed and studied in detail. For the machine with a coil pitch of 1\, all har monics that are not torque producing either directly or through modulation by the stator teeth are eliminated. This results in greater torque perfor mance\, flux weakening capability\, and efficiency than comparable concent rated winding machines. For a coil pitch of 2\, the proposed winding struc ture is able to completely eliminate both the parasitic 1st subspace harmo nic and the largest loss-causing higher order space harmonic such that the rotor and PM eddy current losses are substantially reduced. These machine s are also scaled to 3MW and found to be competitive with the conventional ISW topology presently employed in offshore wind turbine generators. Furt hermore\, the first method for dq-analysis of star-delta wound FSCW machin es is developed which allows for these machines to be used with modern con trol techniques like field oriented and sensorless control in the future. The results of this thesis are validated with analytical modelling\, FEA s imulations\, and experimental measurements of a number of prototypes.\n\nH ost: IEEE Power and Energy Society UK&I Chapter\n\nCo-hosts: IEEE PELS UK& I Chapter\, IEEE IAS UK&I Chapter\, and IEEE PES Student Branch Chapters a t:\n\n- University of Birmingham\n- University of Manchester\n- University of Sheffield\n- University College Dublin\n- Imperial College London\n- U niversity of Strathclyde\n\nThe IEEE UK and Ireland PES Chapter is pleased to announce the winner of the [‘Best PhD Thesis Competition Award’ 20 24](https://www.ieee-ukandireland.org/ieee-uk-and-ireland-pes-chapter-anno unces-best-phd-thesis-competition-award-2024/).\n\nDr Isaac Rudden\, IEEE and PES Member\, received the highest score after gathering the rubric’s form from the judges and carefully summarising them.
