The invention relates to an annular electric propeller supported by a magnetic-liquid composite suspension bearing. The annular electric propeller comprises a shell, a wheel flange type motor, a magnetic-liquid composite suspension bearing system and a propeller. A permanent magnet brushless motor arranged in water is adopted to directly drive the hub-free propeller to rotate, so a middle transmission mechanism is omitted; and the rotor and the propeller assembly are supported by the magnetic-fluid composite suspension bearing system and transmit thrust to the motor and a hull, so the middle transmission loss between the motor and the propeller is reduced, the efficiency is improved, the structure of a propelling system is simplified, and noise, vibration and the like are reduced.
本发明涉及一种磁液复合悬浮轴承支撑的环形电力推进器,包括:壳体、轮缘式电机、磁液复合悬浮轴承系统和螺旋桨。本发明采用置于水中的永磁无刷电机直接带动无毂式螺旋桨转动,省去了中间的传动机构,转子和螺旋桨组件由磁液复合悬浮轴承系统支撑并将推力传递到电机和船体上,降低电机到螺旋桨之间的中间传动损耗,提高效率、简化推进系统结构、降低噪声和振动等。
