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.

双转子同步磁阻电机的分析与设计

为了将同步磁阻电机推向更高的功率密度以满足汽车应用的要求，通过有限元分析对双转子 (DR) 同步磁阻拓扑进行了彻底的分析、设计和研究。这项工作显示了双侧配置相对于单侧定子结构的优缺点。介绍了选择最佳定子/转子组合、磁通屏障数量和设计参数的设计过程。最后，介绍了与传统单转子 (SR) 同步磁阻电机的多物理场比较，以突出所提议的 DR 电机的优势。结果表明，与传统 SR 相比，DR 结构可以产生高 18% 的扭矩和低 41% 的扭矩纹波。
