Abstract
The invention relates to a special three-phase asynchronous motor for ZYS series compressors, which mainly adopts the technical scheme that a front end cover, a back end cover and a motor case are connected and fixed into a motor case, a motor shaft is supported and arranged in the motor case through a bearing assembly, a rotor is arranged on the motor shaft, a stator is arranged on the motor case, a fan is fixed on the motor shaft, and a wind cover is fixed on the back end cover. The invention is characterized in that the shaft end of the motor shaft extends out of the front end cover, and keys are arranged in key slots in front of the motor shaft. A circlip for hole is arranged between the bearing assembly and the front end cover, a wave form leaf spring is arranged between the bearing assembly and the back end cover, and a wiring box is connected on the stator through a screw bolt. The invention can reduce the manufacture cost and raw materials, can reduce the energy consumption, and has small size. The bearing installation and bearing locking mode can be changed according to different connection modes of the compressor and the motor for meeting the requirements of specific conditions of different compressors.
Description
technical field [0001] The invention relates to a special three-phase asynchronous motor for ZYS series compressors, specifically for driving compressor equipment. Background technique [0002] In the prior art, most of the motors used in compressors are two-pole or four-pole motors with high speeds. The ordinary motors used for compressors can no longer meet the specific conditions of the development of compressors to a certain extent. , such as saving materials, reducing energy consumption, reducing volume, improving structure, etc. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a special three-phase asynchronous motor for compressors, which can reduce manufacturing costs and raw materials; reduce energy consumption and small volume; and can meet the specific requirements of the development of compressors . [0004] According to the technical solution provided by the present invention, t...
