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.
