Abstract (EN): The need for higher efficiency motors is becoming more relevant due to recent policies adopted in most advanced economies, which are adopting new minimum energy performance standards. A great effort to optimize several parts of rotating electric machines is being done to fulfill that requirement. Recent studies focus on stator winding optimization, because of its high loss share. In this paper, a general multilayer winding configuration is proposed for winding design optimization for multiphase symmetrical machines, by combining multilayer integer-slot, fractional-slot, and fractional-slot concentrated windings. The constrained minimization of the airgap magnetomotive force harmonic distortion and winding resistance is solved by the hybridization of differential evolution with a non-dominating sorting algorithm. A framework is provided for replication purposes. An experimental application example of standard and optimized windings is included for performance assessment. The optimized winding leads to a significant motor efficiency gain, while reducing the amount of copper needed for manufacturing. © 1986-2012 IEEE.
