针对电动汽车牵引电机提出了π铁芯和双π铁芯开关磁阻电机的概念设计。有限元分析结果表明，与传统SRM相比，π铁心SRM具有定子隔离、磁路短的特点，平均转矩提高了23%，转矩涟漪降低了41%，转矩涟漪和径向力小，具有更好的振动和噪声性能。此外，本文还介绍了双转子π铁心SRM的永磁结构和无永磁结构。这些双转子模型在不久的将来有可能适用于轮毂电机驱动。
Conceptual designs of the π core and dual π core switched reluctance motors have been proposed for traction motors of the electric vehicle. Compared to a conventional SRM, the three-phase π core SRM shows an increased average torque by 23% and reduced torque ripple by 41% from finite element analysis results, due to its characteristics of the isolated stator segments and short flux path. The π Core SRM has better performance in vibration and noise for its much lower torque ripple and radial force. In addition, the dual rotor π core SRMs with and without permanent magnets are introduced in this study. These dual rotor models have their potential applicability to in-wheel motor drives in the near future.
