A shaftless electric propeller for a ship comprises a stator, the stator is tubular, a tubular rotor is arranged in the stator, and the shaftless electric propeller is characterized in that a supporting bearing is arranged between the stator and the rotor, so that the rotor smoothly rotates in the stator; a stator winding is arranged on the stator, and a rotor winding is arranged on the rotor, so that a shaftless motor is formed; the inner wall of the rotor is provided with paddles, and the paddles achieve drainage movement along with rotation of the rotor. The blades are arranged in a spiral line mode, uninterrupted uniform drainage movement is completed in a relay mode, compared with blades arranged in the same plane, the water drainage amount of the blades is increased, and the improvement pushing force of the propeller is improved. By arranging the inner cylinder, the advancing blades, the retreating blades, the advancing blade grooves and the retreating blade grooves, output and stop of power of the propeller and change of the power direction are achieved, wherein the advancing blade grooves and the retreating blade grooves are matched.
一种船用无轴电动推进器,包括定子,所述定子为管状,内设有管状转子,其特征在于:所述定子和转子之间设有支撑轴承,使转子在定子内顺利进行旋转;所述定子上设有定子绕组,所述转子上设有转子绕组,形成无轴电机;所述转子内壁设有桨叶,桨叶随转子的转动实现排水运动。通过桨叶以螺旋线形式的排列,接力的完成不间断的均匀排水运动,相比于同平面排列的桨片,增大了浆叶排水量,提高了推进器的提高推动力。通过设置内筒,前进桨叶、后退桨叶以及本匹配的前进叶槽和后退叶槽,实现推进器动力的输出、停止以及动力方向的变化。
