A three-dimensional (3D) finite element analysis (FEA) is employed to evaluate and identify the endwinding contribution into the overall winding power loss generated. The study is focused on the end-winding effects that have not been widely reported in the literature. The calculated results confirm that the end-winding copper loss can significantly affect the eddycurrent loss within copper and it should be taken into account to provide reasonable prediction of total losses. Several structures of the end-winding are analyzed and compared in respect to the loss and AC resistance. The results clearly demonstrate that the size of the end-winding has a significant impact on the power loss. The calculated results are validated experimentally on the high-speed permanent magnet synchronous machine (PMSM) prototype for selected various winding arrangements.}, type={Artykuły / Articles}, title={Analysis of end-winding proximity losses in a high-speed PM machine}, URL={http://ochroma.man.poznan.pl/Content/85256/PDF/DOI%2010.1515aee-2016-0017.pdf}, doi={10.1515/aee-2016-0017}, keywords={end-winding, permanent magnet motor, eddy-currents losses, proximity losses}, }
