The shaftless underwater double-paddle electric propeller comprises an annular shell of a hollow structure, a stator assembly fixed in the annular shell and rotor assemblies rotatably arranged in the annular shell, the number of the rotor assemblies is two, the rotor assemblies are arranged on the front side and the rear side in the annular shell respectively, the two rotor assemblies are each provided with a plurality of paddles, and the paddles are arranged in the annular shell. The front paddle and the rear paddle are opposite in direction, the front paddle rotates clockwise during working, and the rear paddle rotates anticlockwise during working. The structure of the electric propeller adopts the design of front and back double propellers without a main shaft, so that the cost is lower, and compared with similar single-blade propellers, the electric propeller is stronger in thrust and low in noise.
本发明提供了一种无轴水下双浆电动推进器,包括中空结构的环状外壳、固定在环状外壳内的定子组件、以及可转动设置在环状外壳内的转子组件,所述转子组件为两组,分别设置于环状外壳内的前、后两侧,两组转子组件上均装有多片浆叶,前、后两侧的浆叶方向相反,工作时前侧浆叶顺时针旋转,后侧浆叶逆时针旋转。本发明的电动推进器结构采用无主轴前后双浆设计,不仅成本更低,而且比同类单浆叶推进器推力更强劲且噪音小。
