A Comprehensive Analysis of an Axial Flux Switched Reluctance Motor with Different Number of Rotor Poles

In this paper, two 12/10 and 12/14 axial flux switched reluctance motors (AFSRMs) with the same stator and different number of rotor poles are proposed and compared with each other in terms of flux linkage, flux density distributions, and performance parameters such as static and dynamic torques. To make simulation results more effective, both structures are studied with the same physical parameters. The two proposed structures are simulated using 3D finite element analysis (FEA). The results show that the proposed 12/10 AFSRM outperforms the 12/14 AFSRM in term of average torque. For a better comparison, the steady state characteristics of both motors are obtained using current chopping control (CCC) mode and the results show that the proposed 12/10 AFSRM outperforms its 12/14 counterpart.
