Aircraft and a power unit thereof

Abstract

An aircraft and a power unit thereof. The power unit of the invention having: a stator having at least one pair of stator magnetic assemblies and a bearing sleeve, each of stator magnetic assemblies having a plurality of stator magnetic units, and the stator magnetic units are uniformly arranged circumferentially on the bearing sleeve. A rotor is arranged opposite to the stator and rotatably connected to the stator. The rotor having a plurality of rotor magnetic units, and the rotor magnetic units of the rotor are respectively interacting magnetically with each stator magnetic assembly to provide a driving force for the rotor to rotate relative to the stator. The invention achieves a redundant power device, solving the problem of complete failure in single-motor power unit when power is lost, thereby improving the reliability of the power unit.
