Underwater globular motor propeller

Abstract

The invention provides an underwater spherical motor propeller. A stator core is in a spherical shape, the surface of the spherical stator core is provided with three grooves which are perpendicular to one another along a big circle, three-phase concentrated windings are placed in the grooves respectively and are pairwise perpendicular, the coils of the three-phase windings are connected to an underwater sealing plug by cables, a spherical sealed shell which is fixed with the stator core wraps the stator core, a spherical shell-shaped outer rotor is sleeved on the sealed shell through rubber bearings, the surface of the rubber bearings are provided with flumes, a rotor core is arranged between two rubber bearings, a slim clearance is reserved between the rotor core and the sealed shell, the rotor core, the rubber bearings and a rotor shell are combined together, and propeller blades are fixed on the rotor shell directly. In the invention, the vectored propulsion of the underwater spherical motor propeller is realized, the performance of the propeller is improved and the mechanical structure of the underwater working device is simplified, the mass and the volume of the underwater working device are reduced; therefore, the underwater working device has better utility and higher reliability.

Description

Underwater spherical motor propeller (1) Technical field The invention relates to an underwater vector thruster with a motor as a power device, in particular to a spherical motor with an outer rotor structure. (2) Background technology With the development of motors and their control technology, various forms of motors have been used as power devices for underwater propulsion. However, in current motor propellers, such as the motor propeller with patent No. 200620055186.1, the propulsion motor adopts a traditional structure, the propeller is connected with the rotor through a reducer or other transmission structures, the rotor rotates around a fixed shaft, and the propeller It can only push the load forward and backward in one direction. If you want to change the direction of movement, you need to add a rudder behind the propeller, and change the running track of the load by controlling the angle of the rudder. The increase of the rudder not only leads to underwater work ...
