Torque comparison between a novel Multilayer Switched Reluctance Motor and a custom one

In this paper a custom three phase Switched Reluctance Motor (SRM) with six stator and four rotor salient poles (6 by 4) was designed, simulated and analyzed and it´s produced torque, phase inductance, flux linkage and some other characteristics were obtained by the 3D Finite Element Method (FEM). Then a novel 7-layer 4 by 4 Multilayer SRM (MSRM) with the same volume was designed and under the same conditions was simulated and analyzed. In the latter motor, 3 layers are energized at the same time causing more torque and efficiency and less torque ripple. Both motors were analyzed under different situations and results were attained. Finally prototypes of each one in the laboratory were constructed and tested and the results were compared with the simulations.
