Because Axial Flux Induction Motors (AFIMs) have many advantages over radial flux (conventional) ones, they are increasingly used in industrial applications. So, their performance prediction is an important issue. On the other hand, parameter estimation is an inseparable part of performance prediction. In this paper, a new method, based on the discharge current of stator windings, is presented. In the 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
