Using stator discharge current for the parameter estimation of a single-phase axial flux induction motor

Because axial flux induction motors (afims) have many advantages over radial flux(conventional) ones, they are increasingly used in industrial applications. so, their performance predictionis an important issue. on the other hand, parameter estimation is an inseparable part of performanceprediction. in this paper, a new method, based on the discharge current of stator windings, is presented. inthe proposed method, theoretical and practical discharge currents are compared to calculate coefficients,time constants and parameters. then, calculated parameters are employed in the d-q model of the afim.finally, 3-d finite element analysis and experimental tests are used to verify the proposed method.
