Embodiment Construction

[0053] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0054] see Figure 1 to Figure 3B as shown, figure 1 is a three-dimensional schematic view of the compressor disclosed in the first embodiment, figure 2 for figure 1 The decomposition diagram of Figure 3A for figure 1 sectional schematic diagram of Figure 3B It is a schematic cross-sectional view of the compressor disclosed in the second embodiment. The above-mentioned compressor 10 is a scroll compressor.

[0055] The compressor 10 of this embodiment includes a casing 20 , a motor device 30 and a scroll member 40 . The motor device 30 is disposed in the casing 20 and includes a body 100 , an assembly 200 , a stator 300 and a rotor 400 .

[0056] The body 100 includes an assembly groove 110 and a plurality of first coupling parts 120 surrounding the inner wall of the assembly groove 110. In this embodiment, these fi...

Abstract

A motor device includes a main body, an assembling body, a stator and a rotor. The main body includes a first bearing hole and a plurality of first connectors, and all distances between each of the first connectors and an axle of the first bearing hole are the same. The assembling body has a second bearing hole. The stator includes a passage and a plurality of second connectors, the second connectors are coupled to the first connectors respectively to have the stator assembled in the main body, and the passage and the first bearing hole are coaxial. The rotor is disposed inside the passage and two ends of the rotor are installed in the first bearing hole and the second bearing hole respectively. By having both the stator and the rotor positioned by the main body, a gap between the rotor and the stator can be maintained consistently.

Description

technical field [0001] The invention relates to a compressor and its motor device, in particular to a compressor and its motor device for scroll compressors. Background technique [0002] The compressor is one of the main components of the mechanical refrigeration system and also the source of power for the mechanical refrigeration system. Compressors can be divided into reciprocating compressors, rotary compressors, and scroll compressors according to different motion modes. Among them, the scroll compressor is often used in the split air conditioner because of its simple operating principle, high stability and low noise. However, in general small scroll compressors, the motor stator is directly assembled on the housing in a tight fit. In other words, the outer diameter of the motor stator is the same as the inner diameter of the compressor casing and closely matched. However, for some medium and large scroll compressors, if the outer diameter of the motor stator cannot b...
