The invention belongs to the field of electric propulsion motor systems for vertical take-off and landing electric aircrafts, and particularly relates to a contra-rotating double-rotor electric propulsion motor for a vertical take-off and landing electric aircraft, which comprises a motor shell assembly, a stator assembly and two rotor assemblies, a gap is formed between the two rotor assemblies; the stator assembly is arranged between the inner wall of the shell and the outer rings of the two rotor assemblies; wherein the axial length of the stator assembly is larger than the sum of the axial lengths of the two rotor assemblies, and the number of pole pairs of the permanent magnets of the two rotor assemblies is different. The device realizes contra-rotation and non-constant-speed operation of the double rotors.
本发明属于垂直起降电动飞机用电推进电机系统领域,具体涉及一种垂直起降电动飞机用对转双转子电推进电机,包括:电机壳体组件、定子组件以及两个转子组件,电机壳体组件沿轴向在电机壳体组件内依次设置有两个转子组件,且两个转子组件之间有间距;定子组件设置于壳体内壁与两个转子组件的外圈之间;其中,定子组件的轴向长度大于两个转子组件在轴向的长度之和,且两个转子组件的永磁体的极对数不同。本装置实现双转子对转且不等速运行。
