摘要: Double-stator switched reluctance motors (DSSRMs) are gaining much attention due to advantages of higher power/torque density and lower acoustic noise compared conventional SRMs. In this paper, a novel three-phase 12/8/12-pole DSSRM design method is proposed by multiple pole arcs optimization for torque ripple applications. A constrained quadrilateral first presented restrict the combinations according motor operation conditions. Then, parametric analysis processes employed analyze effects on static in 3-D finite-element modeling environment. order select optimal generating torque, an effective evaluation principle presented. Instead 22.5° rotor position range, 15° range adopted calculate average profiles, which more evaluate capability. The selected considers not only excitation demagnetization phase currents but also generation. Finally, achieve ripple, transient simulation further carried out identify comparing efficiency.
