To push the synchronous reluctance machine toward higher power densities to meet the requirement of automotive applications, a double-rotor (DR) synchronous reluctance topology has been thoroughly analyzed, designed, and investigated by means of finite-element analysis. This work shows the pros and cons of the double-sided configuration with respect to the single-sided stator structures. The design process for selecting the best stator/rotor combination, flux barrier number, and design parameters is presented. Finally, a multiphysic comparison with a conventional single-rotor (SR) synchronous reluctance machine to highlight the benefits of the proposed DR machine has been presented. It is found that the DR structure can produce 18% higher torque and 41% lower torque ripple compared to the conventional SR.
