要約(英語): The quantification of stray load losses such as circulating-current loss in armature windings and in-plane eddy-current loss in electrical steel sheets is important for developing rotating machines with high efficiency. The circulating-current loss in parallel-connected armature windings is analyzed by using the two-dimensional finite element method. We investigate the losses caused by the in-plane eddy-current in the stator cores of permanent-magnet synchronous machines by using the three-dimensional finite element method. The influences of the coil-end structure, skew structure, and carrier harmonics of a pulse-width-modulated inverter on the in-plane eddy-current loss in the stator core are described. The accuracy of the analyses is confirmed through comparison with experimental results.
