Document Type and Number:
WIPO Patent Application WO/2018/201890
Kind Code:
A1
Abstract:
Provided is a propeller for a submersible, comprising: a housing (1) having a cylindrical structure with two open ends; a stator sleeve (2), which is a cylindrical structure with one end open and is suspended in an internal cavity of the housing (1); a motor stator (3) fixed inside the stator sleeve (2); a rotor sleeve (4), which is a cylindrical structure with one end open, and is 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 side wall of the rotor sleeve (4). The propeller (6) of the underwater propeller is directly fixed on 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.
