Design of electrical machines aided by field calculation and factorial experiments method.

Abstract

An approach for electrical machines design by using magnetic field computation coupled to factorial experiments is presented is this paper. Principles of factorial experiments are briefly reviewed and their application to design optimization is explained. In this application, experiments are replaced by magnetic field calculations. The procedure, which performs autmatically all the required numerical field calculations, is described. The whole procedure is applied to a typical problem concerning permanent magnet motors with polar pieces.
