Abstract
This article delves into simultaneously applying the modular stator and segmented rotor to switched reluctance motors (SRMs). In this regard, a new double-stator segmented-rotor modular SRM (DSSR-MSRM) with a new pole combination is proposed. First, the motor topology is introduced and the magnetic circuit model of the motor is analyzed. Next, the electromagnetic performances of the machine are analyzed using a finite-element analysis (FEA). The superiority of the DSSR-MSRM in terms of flux linkage and torque is illustrated based on a comparative study with five various types of SRMs with modular/nonmodular and segmented/nonsegmented structures with the same dimensions and parameters. The simulation results indicate that the DSSR-MSRM has higher torque compared to the other structures. Moreover, the dynamic performances of the proposed motor in terms of current, torque, and power waveforms are obtained. In addition, it is shown that the proposed motor has low torque ripple. Finally, the prototype motor is built, the mechanical considerations are discussed, and the experimental results are obtained, which are in a good agreement with those predicted from the FEA.
