The invention discloses a helicopter duct tail rotor magnetic suspension electric drive structure which comprises a stator support, a machine shell, blades, a permanent magnet synchronous motor, a first magnetic suspension system, a second magnetic suspension system and a mechanical protection bearing. The stator support is sequentially provided with a support inner shaft, supporting strips and a support outer ring from inside to outside, the support inner shaft and the support outer ring are coaxial, the support inner shaft and the support outer ring form a whole through the evenly-distributed supporting strips, and the evenly-distributed supporting strips can provide a wiring channel while reducing the weight of the stator support. The magnetic suspension system is adopted to replace a mechanical bearing for supporting, abrasion of a traditional mechanical bearing of the helicopter ducted tail rotor is eliminated, controllable electromagnetic force is generated through the magnetic suspension system, disturbance of air to a helicopter ducted tail rotor direct-drive type electric system is controlled in real time, and the reliability of the helicopter ducted tail rotor direct-drive type electric system is improved. Vibration generated by air disturbance is reduced, and the flight stability and safety of the helicopter are further improved.
本发明公开了一种直升机涵道尾桨磁悬浮电驱动构型,包括定子支架、机壳、桨叶、永磁同步电机、第一磁悬浮系统、第二磁悬浮系统以及机械保护轴承;所述定子支架由内向外依次为支架内轴、支承条、支架外环,所述支架内轴与所述支架外环同轴,并由均布的所述支承条构成一个整体,均布的所述支承条在降低所述定子支架重量的同时,还能提供布线通道。本发明通过采用磁悬浮系统替代机械轴承进行支承,消除了直升机涵道尾桨传统机械轴承的磨损,通过采用磁悬浮系统产生可控的电磁力,对空气给直升机涵道尾桨直驱式电动系统带来的扰动进行实时控制,降低了由空气扰动所产生的振动,进一步提升了直升机飞行的稳定性与安全性。
