Abstract
Provided is a propeller for a submersible, comprising a housing (1) having a cylindrical structure with two open ends, a stator sleeve (2) having a cylindrical structure with one open end, the stator sleeve suspended in an internal cavity of the housing (1), a motor stator (3) fixed inside the stator sleeve (2), a rotor sleeve (4) having a cylindrical structure with one open end and disposed on the stator sleeve (2), a motor rotor (5) fixed to an inner wall of the rotor sleeve (4), and a propeller (6) fixed to an outer wall of the rotor sleeve (4). The propeller (6) of the underwater propeller is directly fixed to the rotor sleeve (4) so that the structure of the motor is compact, and the rotational shaft transmission is not required so that the length of the propeller is shortened and the volume is reduced.
