The invention relates to an underwater propeller which aims at removing noise caused by a bearing gearbox and the like and improving the propelling efficiency. A three-phase multi-pole direct-current brushless inner rotor motor is adopted as an underwater propeller to directly drive a propeller, and an axial thrust bearing and a supporting bearing are replaced by the principle of homopolar repulsion of permanent magnets. The device has the advantages of being simple in structure, high in efficiency, wide in application range, higher in practicability and the like, and has certain application and popularization value.
本发明涉及了一种旨在去除轴承变速箱等引起的噪声,提高推动效率的水下推进器。本发明采用以三相多极直流无刷内转子电机作为水下推进器直接驱动螺旋桨,利用永磁体同极相斥的原理替代轴向推力轴承和支撑轴承。本发明的特点包括结构简单、效率高、适用范围广以及实用性更强等,具有一定的推广使用价值。
