چکیده :

Switched reluctance motors (SRMs) are popular motors for industrial applications thanks to their robustness. However, they offer low torque. The main objective of this article is to apply permanent magnets (PMs) in the structure of SRMs to enhance their torque. To this end, a new PM-SRM is analyzed. First, the topology is introduced and its working principle is delineated. Three-dimensional finite element method (FEM) is employed to extract the results including flux densities, flux linkage, and torque. It is proved based on the simulations that the proposed PM-SRM offers higher torque than the original topology. Due to the presence of the PMs, the introduced PM-SRM has lower flux linkage and saturation level than the SRM under all excitation currents. Moreover, the new motor has a very low cogging torque, which is another advantage for this motor.
