“…Structural design modification, also referred as passive method, can bring the torque ripple reduction in machines [15]. The turn on and turn off angle optimization of power converter can also mitigate the ripples in average torque [16]. The shaping of phase currents through controlled switching of the converter, also called as active method, is employed to reduce the torque ripple [17,18].…”

High torque and power generation capability of double-stator axial flux switched reluctance motor (DSAFSRM) makes it superior to conventional and segmented rotor switched reluctance motors. Despite its significant feature, the ripple in developed torque still limits the usefulness of DSAFSRM for widespread industrial application. This paper proposes an 8/6/8 pole DSAFSRM with modification in rotor pole shape to reduce torque ripples in respective model. The respective phase windings of the upper and lower stators are excited externally by preparing the circuit in Maxwell software. Each rotor tooth is constructed with two types of slots with different levels of air gap to change the inductance profile. Firstly, the design of a conventional DSAFSRM has been presented; thereafter, some geometric modifications in the rotor tooth have been suggested and investigated to obtain a lower torque ripple at 1200 rpm in the proposed DSAFSRM. The efficacy of the proposed motor is investigated through finite element method (FEM) based analysis and also by comparative analysis with other types of switched reluctance motors. It can be inferred from the simulation results that the torque ripple is significantly reduced by 55.62% in the proposed DSAFSRM compared to the conventional DSAFSRM. However, the efficiency of the proposed DSAFSRM (73.87%) is slightly less than the conventional DSAFSRM (74.65%).

“…In toothed SRMs (TSRMs), the structural modification in the leading edge of the rotor poles with fillet reduces the torque ripple [15]. The addition of a semi-oval auxiliary core on both sides of rotor tooth alleviates the torque ripple [16]. In active method, the shaping of phase currents through switching control is employed to reduce the torque ripple [17,18].…”

Double-stator switched reluctance motors (DSSRMs) acquire attention because of their high torque/power generating capability compared to conventional and segmented rotor switched reluctance motors. One of the main limiting performance indices of such motors for industrial applications is its high torque ripple. This paper proposes a 12/10/12 pole DSSRM with an angular shift of half of the stroke angle between inner and outer stators. The respective phase windings of the inner and outer stators are parallelly excited with the same phase angle shift to reduce the torque ripple. Each rotor segment is constructed with a pair of half rotor segments that are isolated from each other through the insertion of a non-magnetic isolator between them. Firstly, the design hypothesis for a low torque ripple DSSRM has been presented; thereafter, some geometric modifications have been suggested and investigated to obtain a nearby response in the proposed DSSRM. The calculation of the width of the non-magnetic isolator, modification in the pole height of outer stator and modification in the arc angles of rotor segments/stator poles are discussed in detail. The effectiveness of the proposed motor is investigated through a 2D finite-element modelling and simulation in ANSYS/MAXWELL software. Simulation results show that the torque ripple is significantly reduced by 74.9% in the proposed DSSRM compared to the baseline DSSRM.
