The invention relates to an annular electric propeller driven by multiple motors in the circumferential direction. The annular electric propeller comprises a shell, a motor driving unit, a magnetic-liquid composite suspension bearing system and a propeller, the motor driving unit comprises a common rotor assembly and a plurality of stator assemblies, the common rotor assembly is arranged on the inner side of the shell, the stator assemblies are annularly distributed in the shell at intervals in the circumferential direction of the shell, and the stator assemblies and the common rotor assemblyform a multi-stator-single-rotor pair. The annular electric propeller is simple in structure, high in propulsion efficiency, low in vibration noise, high in safety and redundancy and low in starting current, can be applied to electric ships, and is particularly suitable for electric ships limited by shallow draught environments of inland rivers and lakes.

    本发明涉及一种周向多电机驱动的环形电力推进器,包括:壳体、电机驱动单元、磁液复合悬浮轴承系统和螺旋桨,所述电机驱动单元包括:公共转子组件和多个定子组件,所述公共转子组件设置于所述壳体的内侧,所述多个定子组件沿所述壳体周向间隔环布于所述壳体内且与所述公共转子组件形成多定子‑单转子副。本发明结构简单、推进效率高、振动噪声低、安全性和冗余度高、启动电流低,可应用在电动船舶上,尤其适合于内河和湖泊浅吃水环境限制的电动船舶。
