The invention relates to a contra-rotating propeller type electric propeller supported by a magnetic liquid composite suspension bearing. The contra-rotating propeller type electric propeller comprises an annular shell and propelling units, and the forward rotating propelling unit and the reverse rotating propelling unit are coaxially arranged in the annular shell in parallel front and back; and apropeller of the forward rotating propelling unit and a propeller of the reverse rotating propelling unit are opposite in rotation directions and are used for generating thrust in the same direction.Two wheel flange type permanent magnet brushless motors are coaxially arranged front and back, each wheel flange type permanent magnet brushless motor drives a corresponding hub-free propeller, the electrically-driven combined contra-rotating propeller is formed, the overall propelling efficiency is improved, and the contra-rotating propeller effect is achieved.

    本发明涉及一种磁液复合悬浮轴承支撑的对转桨式电力推进器,包括:环形壳体和推进单元,正转推进单元和反转推进单元前后同轴并列设置于所述环形壳体内;所述正转推进单元的螺旋桨与所述反转推进单元的螺旋桨的旋向相反,用于产生同样方向的推力。本发明前后同轴布置二个轮缘式永磁无刷电机,各驱动一个无毂式螺旋桨,形成电力驱动的组合式对转螺旋桨,提高了整体的推进效率,起到对转桨的效果。
