Fast Sizing Procedure for Salient-Pole Wound Field Synchronous Motors for Transportation Electrification

This is the authors' abstract. We don't add key points for this paper.

This paper presents an electromagnetic sizing procedure for the preliminary design of wound field synchronous motors for traction applications. The rated data, the permissible electromagnetic loadings, and few initial geometry and winding specifications are requested as input for the algorithm. The procedure is based on an analytical-numerical approach, consisting of increasing the machine rotor diameter until the requested performances are obtained respecting all the imposed constraints. A preliminary lamination geometry is built only using analytical equations and considering the no-load operating conditions of the machine. The sizing procedure is therefore completed at rated load using finite element simulations. In this paper, the proposed procedure is validated on a highly engineered wound field synchronous motor used for transportation applications.
