The invention provides an underwater shaftless propeller based on a permanent magnet motor, and relates to the field of motors. The first cooling channel is arranged in the end cover, the first cooling channel is an open channel, an inlet and an outlet of the first cooling channel extend to the outside of the end cover, and the inlet and the outlet are respectively connected with the cooling box; the second cooling channel is fixed on the outer side of the permanent magnet motor rotor, and the second cooling channel is a closed channel integrally formed by a tough material; when the shaftless propeller is started, the cooling liquid in the first cooling channel is conveyed and flows by the cooling box, the second cooling channel rotates along with the rotor of the permanent magnet motor, and the cooling liquid in the second cooling channel flows along with the change of the rotating speed of the rotor of the permanent magnet motor. The reversing mechanism is arranged on the shell and provides pitching angle adjustment for the shaftless propeller. According to the underwater shaftless propeller, a more efficient cooling mode and a more flexible power direction are provided.
本发明提供了一种基于永磁电机的水下无轴推进器,涉及电机领域。第一冷却通道,设置在端盖内,第一冷却通道为开放通道,第一冷却通道的入口和出口延伸至端盖的外部,入口和出口分别与冷却箱连接;第二冷却通道,固定在永磁电机转子的外侧,第二冷却通道为由韧性材料一体成型的封闭通道;在无轴推进器启动的状态下,第一冷却通道内的冷却液由冷却箱输送流动,第二冷却通道随着永磁电机转子转动,第二冷却通道内的冷却液随着永磁电机转子的转速变化而流动。换向机构设置在外壳上,为无轴推进器提供俯仰角度的调节。本发明的水下无轴推进器,提供更高效的冷却方式和更灵活的动力方向。
