Permanent magnet rotor structure for underwater motor, underwater motor and underwater equipment

Abstract

A permanent magnet rotor structure for an underwater motor, an underwater motor and underwater equipment, related to the field of motors. The permanent magnet rotor structure for the underwater motor includes a rotor end cover; a plurality of permanent magnets arranged on an inner circumferential surface of the rotor end cover; a protective attachment structure arranged on surfaces of the plurality of permanent magnets; and an adhesive layer for adhering the protective attachment structure to the surfaces of the plurality of permanent magnets and covering the protective attachment structure. The permanent magnet rotor structure has characteristics of corrosion resistance and wear resistance, so that the service life of the underwater motor comprising the permanent magnet rotor structure can be prolonged.
