Abstract

When designing a universal finite element software for analyzing a permanent magnet synchronous motor, the relative position of the stator and rotor remains unknown. However, determining the relative position is a precondition for electromagnetic field calculation. Through analyzing the basic relationship of variables in a synchronous machine, the characteristics of an air-gap-resultant electromotive force and an inner power angle under a special inner power factor angle are obtained. A method similar to inverse problem solving is proposed. A series of electromagnetic field calculation under different armature current initial phase angles are carried out, and through searching the field of a special inner power factor angle, the relative position of the rotor and the stator can be determined subsequently.
