Optimum design criteria based on the rated Watt of a synchronous reluctance motor using a coupled FEM and SUMT

This paper deals with an automatic design standard computation based on a rated watt for a synchronous reluctance motor (SynRM). The focus of this paper is making the design relative to the output power on the basis of the rotor shape of a SynRM in each rated watt using a coupled finite element method and sequential unconstrained minimization technique. The coupled finite elements analysis and Preisach model have been used to evaluate nonlinear solutions. The proposed procedure allows to define the rotor geometric dimensions according to the rotor diameter and rated watt starting from an existing motor or a preliminary design.
