本文对用于主飞行控制面机电驱动的容错磁齿轮伪直接驱动 (PDD®) 电机的电磁设计和性能进行了研究。结果表明，存在大量高速转子（HSR）极对数、极片数和定子槽数的组合，可以实现双工三相容错配置。此外，除了有助于降低质量的解决方案之外，还表明，与直接驱动或机械齿轮电机解决方案相比，PDD 相对于螺杆的惯性显着降低。这些发现在原型 PDD 上得到了验证，该原型的设计和制造是为了满足主控制表面机电执行器的要求。
This paper presents an investigation into the electromagnetic design and performance of a fault-tolerant magnetically geared Pseudo Direct Drive (PDD®) electrical machine for primary flight control surface electromechanical actuation. It is shown that a large number of combinations of high-speed rotor (HSR) pole pairs, pole-piece numbers, and stator slot numbers exist for which a duplex 3-phase fault tolerant configuration can be realized. Furthermore, in addition to facilitating a lower mass solution, it is also shown that a PDD presents a significantly lower inertia referred to the screw, when compared to direct-drive or mechanically geared motor solutions. The findings are validated on a prototype PDD, which has been designed and built to meet the requirements of primary control surface electromechanical actuator.
