Finite element analysis and experimental verification of high reliability synchronous reluctance machine

Abstract

The aim of this study was to investigate and analyse the synchronous reluctance machine. An accurate method for determining the lumped parameters of an equivalent circuit of the studied machine has been proposed. The method is based on the phase currents and voltages analysis at low slip operation. Experimental research of a synchronous reluctance machine is supplemented by simulation studies. The field-circuit model of electromagnetic phenomena in the considered motor was developed and used in simulation. The proposed method allows the numerical model to be verified by comparing the calculated and measured torqueangle characteristics of the machine. The test results obtained are presented and discussed. Achieved satisfactory concordance between simulation and experiment results proves that the proposed approach can be useful in the synthesis of reliable synchronous reluctance machines as well as in their control systems.
