The need of magnet-less machine for industrial applications are increasing, and one of the most common magnet-less machine is switched reluctance machine. Switched reluctance machine utilises the basic concept of attraction and repulsion principle, and together with the air-gap reduction an improvement in the production of the torque generation is separated earlier. The concept of dual air-gap to improve the torque density of the switched reluctance machine is attempted by researchers in recent times. The concept of dual air-gap shows a high starting torque density in the machine which allows an early steady state in the machine performance compared to the conventional machine. As the drawback, the dual air-gap machine is not able to produce higher torque average and drags is presence for industrial application. Therefore, a novel through modification of magnetic circuit of the dual air-gap in double rotor switched reluctance machine is proposed. In this paper, a comparison in terms of motor torque constant square density between three machines of conventional switched reluctance machine (SRM), double rotor switched reluctance machine (DRSRM), and the proposed dual air-gap machine is presented. The results shows that there is an improvement in the average torque by 13% compare to the SRM and 39% compare to the DRSRM. The proposed dual air-gap machine, it is also showing an improvement in motor constant square density by 37% and 114% of SRM and DRSRM, respectively.
