The invention discloses a submarine propulsion system and a submarine, and relates to the technical field of submarines, the submarine propulsion system comprises a power unit, the power unit comprises a plurality of groups of propulsion mechanisms distributed at intervals, each propulsion mechanism comprises an impeller assembly and a driving assembly, a brushless motor rotor is fixedly connected with an impeller, and rotation driving of paddles is completed; when the submarine runs at a high speed, high-speed incoming flow directly rushes into the gaps among the paddles and is not shielded by the submarine body, so that the water flow speed at the inlet of the engine is higher. The brushless motor rotor and the brushless motor stator are arranged on the periphery of the submarine body, so that the rotating speed of the impeller depends on rushing in of high-speed incoming flow and can be further increased, the rotating speed of the driving assemblies is higher, the relative linear speed between the brushless motor rotor and the brushless motor stator is also increased, and the output efficiency of the driving assemblies is higher. The circular radius of the position where the stator coil is located is larger than that of the position where the stator coil is concentrated in the middle of the tail, and the larger coil position radius will bring higher torque.

    本发明公开一种潜艇推进系统及潜艇,涉及潜艇技术领域,包括动力单元,所述动力单元包括多组间隔分布的推进机构,所述推进机构包括叶轮组件和驱动组件,依靠无刷电机转子和叶轮相固定连接,完成对桨叶的旋转驱动,潜艇在高速行驶时,高速来流直接冲入桨叶之间的空隙,而不被艇体所遮挡,所以发动机入口的水流速度较高。因此叶轮的转速依赖高速来流的冲入,可以进一步被提升,所以驱动组件转速就更高,无刷电机转子和无刷电机定子之间的相对线速度也会提高,使得驱动组件的输出效率更高,本发明中潜艇的驱动组件分布在艇体周围,定子线圈所处位置的圆形半径,比集中在尾部中间位置时更大,更大的线圈位置半径,将带来更高的转矩。
