Design Modeling and Sizing Equations of V-shape IPM Motors

Abstract

The paper develops the model of a V-shape IPM motor for automotive applications. The approach, design oriented, considers saturation and cross-coupling, by suited saturation factors. A torque sizing equation is obtained, independent on the winding data, and the main constructional data are gained, considering the corner operating point. Then the detailed motor design is completed, and the calculation of the torque-speed curve is extended also in the flux-weakening zone. FEM analysis validates the model.
