Title:
WATER-COOLED MOTOR STRUCTURE FOR COAXIAL PUMP
Document Type and Number:
WIPO Patent Application WO/2023/019422
Kind Code:
A1
Abstract:
A water-cooled motor structure for a coaxial pump, relating to the technical field of machinery. The present invention solves the problems that existing traditional water-cooled motors are provided with special water-cooled components and are complex in structure, large in installation difficulty, and difficult to maintain. The water-cooled motor structure for the coaxial pump comprises: a motor housing, a front end cover (2), a rear end cover (11), a stator (12), a rotor (13), and a rotating shaft (14); a water-cooled motor framework (9) is provided in the motor housing; the motor housing is composed of an outer shell (7) and an inner shell (10); the water-cooled motor framework (9) is provided between the outer shell (7) and the inner shell (10); a plurality of water flow through holes (16) are evenly formed in the circumferential wall of the water-cooled motor framework (9) at intervals in the circumferential direction; and when the water flow through holes (16) are filled with cold water, the cooling effect on a motor structure is achieved by means of the cold water.
