The invention relates to an axial flux motor driven contra-rotating paddle type electric propeller. The propeller comprises propeller units; each propeller unit comprises a shell, an axial flux motor,a propeller and a bearing assembly; the forward propeller unit and the reverse propeller unit are coaxially arranged side by side in a front-back direction; the rotating direction of the propeller ofthe forward propeller unit is opposite to that of the propeller of the reverse propeller unit, so that thrust in the same direction can be generated. With the axial flux motor driven contra-rotatingpaddle type electric propeller of the invention adopted, the intermediate transmission loss between the motors and the propellers is decreased; efficiency can be improved, the structure of the propulsion system is simplified, and noises and vibration are reduced.
本发明涉及一种轴向磁通电机驱动的对转桨式电力推进器,包括推进器单元,所述推进器单元包括:壳体、轴向磁通电机、螺旋桨和轴承组件,正转推进器单元和反转推进器单元前后同轴并列设置,且所述正转推进器单元的螺旋桨与所述反转推进器单元的螺旋桨的旋向相反,用于产生同样方向的推力。本发明降低了电机到螺旋桨之间的中间传动损耗,具有提高效率、简化推进系统结构、降低噪声和振动等特点。
