摘要: 针对光热电站降低定日镜驱动电机成本、抑制定日镜驱动电机振动的双重需求,本文以开关磁阻电机为基础,设计永磁体辅助式外转子开关磁阻电机( permanent magnet assisted external rotor switched reluctance motor,PMa-ERSRM) 。 基于电磁-振动耦合机理,设计双开槽外转子、极靴外转子、齿顶开槽外转子及极靴- 齿顶开槽外转子 4 种结构,以普通外转子为基准,研究了开槽参数对转矩脉动和径向电磁力密度的影响;探究了径向电磁力密度的
空间、时间以及时空特性分布;分析了不同转子结构的固有频率与振动频率响应。 仿真结果表明,在所提出的 4 种结构中,双开槽转子结构抑制振动效果表现最优,可降低振动位移 58. 6%、振动速度 29. 8%及振动加速度 38. 3%,为定日镜驱动电机的设计提供了新方案,也为外转子开关磁阻电机抑制振动问题的研究提供了参考。

Abstract: To address the dual requirements of reducing drive motor costs and suppressing vibrations in heliostat drive motors for solar thermal power plants, this paper designs a permanent magnet assisted external rotor switched reluctance motor ( PMa-ERSRM) based on the switched reluctance motor ( SRM) principle. Based on the electromagnetic-vibration coupling mechanism, four structural designs were developed: double-slotted outer rotor, pole shoe outer rotor, tooth-top slotted outer rotor,and pole shoe-tooth-top slotted outer rotor. Using the standard outer rotor as a reference,the influence of slotting parameters on torque ripple and radial electromagnetic force density was investigated. The spatial, temporal, and
spatiotemporal characteristics of radial electromagnetic force density distribution were explored. The natural frequencies and vibration frequency responses of different rotor structures were analyzed. Simulation results indicate that among the four proposed structures, the double-slotted rotor exhibits optimal vibration suppression, reducing vibration displacement by 58. 6%, vibration velocity by 29. 8%,and vibration acceleration by 38. 3%. This provides a novel design approach for suntracking motor drives and offers valuable insights for vibration suppression research in external rotor SRM motors.

Key words: permanent magnet-assisted switched reluctance motor, torque pulsation, rotor slotting, radial electromagnetism
