Direct-current water fetching motor for air conditioner

Abstract

A direct-current water fetching motor for an air conditioner comprises an upper end cover and a lower end cover which are vertically arranged in a spaced mode; a stator assembly is arranged in the upper end cover; a rotor assembly is arranged in the lower end cover; the rotor assembly is arranged outside the stator assembly in a sleeving mode; a rotating shaft is arranged at the axis of the lower end cover; the rotating shaft upwards penetrates through the upper end cover and extends upwards; a circuit board is further arranged in the upper end cover above the stator assembly; the circuit board is electrically connected with the stator assembly; a first extending part protruding upwards is arranged on the upper end face of the upper end cover; a second extending part extending downwards is arranged on the lower end face of the upper end cover; the second extending part and the first extending part are coaxially arranged with the rotating shaft; shaft holes penetrating up and down are formed in the second extending part and the first extending part; bearings are arranged in the shaft holes; the rotating shaft is inserted in inner rings of the bearings in a penetrating mode; and the stator assembly is fixedly arranged on the outer wall of the second extending part in a sleeving mode.

Description

technical field [0001] The invention relates to a direct current water pumping motor for an air conditioner. Background technique [0002] The existing DC water-pumping motors for air conditioners are installed inside through the stator, and the rotor is installed outside through the casing and the rotating shaft to realize the rotor. However, the existing external rotor motor has poor overall structure stability, which leads to the installation stability of the rotating shaft of the motor. If it is not guaranteed, it is prone to eccentricity during long-term use; [0003] For this reason, be badly in need of a kind of air-conditioning with good stability to solve this problem with direct-flow water-feeding motor. Contents of the invention [0004] The purpose of the present invention is to provide a kind of DC water pumping motor for air conditioners with good stability; [0005] A DC pumping motor for air-conditioning designed according to this purpose, comprising an u...
