The work presented in this paper proposes a method for rapidly evaluating electric machine performances on drive cycle based on kriging metamodel. The driving cycle is considered through the k-means method to reduce the number of operating points. Thus, a metamodel of the machine's total losses is deduced on the centroids obtained by k-means. It is implemented after an evaluation of a finite element model in MotorCAD. This methodology is applied to design a buried permanent magnet synchronous machine. The optimization over the driving cycle is performed based on this metamodel. Finally, a comparison is made between the results obtained by optimization and the evaluation of these optimal solutions in MotorCAD.
