Problems solved by technology

This structure puts forward high requirements on the sealing performance of the flange connection end faces of the upper end cover, the shell and the lower end cover. If the sealing is not good, it is easy to leak water from the flange connection end faces, and the flange connection needs to be disassembled for maintenance, which is time-consuming. Trouble

Abstract

The invention discloses a water-cooled motor, which comprises an upper end cover, a shell, a lower end cover, a motor shaft, a stator, and a rotor; a water inlet joint II and an outlet joint II communicating with the cavity interlayer II are arranged on the outer wall of the shell circumference; The outer wall of the lower end cover is provided with the water inlet joint III and the water outlet joint III which communicate with the interlayer III of the cavity; the outer wall of the upper end cover is provided with the water outlet joint I and the water inlet joint I which communicate with the interlayer I of the cavity; Ⅲ communicates with the water inlet joint II of the shell through the pipeline; the water outlet joint II of the shell communicates with the water inlet joint Ⅰ of the upper end cover through the pipeline to form a bottom-up cooling water channel; further improvement lies in: the upper end cover, the shell, the lower end The covers are all welded components; the upper end cover and the lower end cover are respectively provided with temperature sensors. The invention has the advantages of convenient maintenance, low manufacturing cost and short manufacturing cycle.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a water-cooled motor. Background technique [0002] The existing water-cooled motor includes an upper end cover, a housing, a lower end cover, a motor shaft, a stator, and a rotor. The housing is a cylindrical member provided with a cavity interlayer, and the lower end cover is a disc-shaped member provided with a cavity interlayer. The outer wall is provided with joints communicating with the interlayer of the cavity, and the upper end cover is a disc-shaped member with an interlayer of the cavity, and the outer wall of the circumference is provided with joints communicating with the interlayer of the cavity, and the cavity of the upper end cover, the shell, and the lower end cover The interlayer communicates through the holes connecting the flanges to form an internally communicated cooling water channel. This structure puts forward high requirements on the sealing performance ...
