Abstract

Based on traditional DC brushless motor, the disclosed structure integrates pressure compensation device with main body of electrical motor. The pressure compensation device is composed of up capping, spring, piston, contact switch, and body case of electrical motor. Being installed inside of the body case, the piston and the case form clearance fit. Spring is installed between the piston and the up capping. Being inside the motor, the contact switch is under the piston. The structure is capable of detecting and controlling running state of electrical motor, and ensuring sealing performance of electrical motor underwater operational environment. Advantages are: almost no limited depth of underwater operation, reliable performance of underwater electrical motor, compact structure, low failure rate, and good security. The invention is applicable to underwater robot, underwater operation tools and relevant industries of aquatic product.

Description

technical field [0001] The invention relates to the main structure of an underwater motor, in particular to realize an underwater direct-current brushless oil-filled motor structure that can adapt to various depths of underwater operations, has a compact structure, low failure rate, and good safety. It is suitable for various underwater robots, underwater operation tools and related aquatic industries. Background technique [0002] The main body of traditional underwater motors is mostly a vacuum cavity structure, and its structure is large; some underwater oil-filled motors that have appeared in recent years have their main structure and pressure compensation device arranged separately, which takes up a lot of space. The above structure makes the underwater motor still have a lot of room for development in terms of operating depth, compact structure, failure rate and safety. Contents of the invention [0003] The purpose of the present invention is to provide an underwat...
