Problems solved by technology

Therefore, there will be problems such as increasing the number of parts and complicating the assembly process.
At the same time, since there is no separate measure for fixing the insulating paper (12), it is only placed between the bracket (2) and the end coil (3C') on the upper end of the stator (3), so quality problems will increase, resulting in compressor failure. Reliability issues, etc.

Embodiment Construction

[0026] Hereinafter, the hermetic compressor stator device of the present invention will be described in detail with reference to the accompanying drawings:

[0027] like Figure 4 , 5 As shown, the stator (30) and the rotor (40) (indicated by dashed lines) together provide driving force for the operation of the compressor. The composition of the stator (30) is: the stator iron core (32) is formed by folding a plurality of metal plates, penetrates the center, and drills holes to form a rotor hole (33). The rotor (40) is arranged inside the rotor hole (33). There is a certain gap between the outside of (40) and the inner surface of rotor hole (33). On the stator core (32), a plurality of slits (not shown) are formed in the same direction as the rotor hole (33). ) is connected on one side. There are wound coils (35, 37) in the slit, and the coils (35, 37) are automatically wound from one slit to another adjacent slit respectively, and are connected with the adjacent slit, and...

Abstract

The invention is a stator device of sealed compressor, including a stator iron core and coils, there is a rotor hole made in the center of the stator iron core, there are many gaps through the rotor hole, the coils are wound up and down in the gaps, an outside coil is the first coil and an inside coil is the second coil. There is insulating paper installed between the two coils, the top end of the insulating paper covers the outside coil and straight extends to the outside surfaces at the top end of the two coils to form shields. The shields formed of a whole insulating paper are mutually separated, and at least above two shields are formed, thus able to prevent the voltage disruption between each coil and the bracket, and at the same time, because the shields are firmly installed, they can prevent the compressor failure during running course.

Description

technical field [0001] The invention belongs to equipment of a hermetic compressor, in particular to a stator device of a hermetic compressor. Background technique [0002] like figure 1 As shown, the existing structure of the hermetic compressor includes: the hermetic shell (1) is composed of an upper shell (1t) and a lower shell (1b). A bracket (2) is arranged inside the sealed housing (1), the bracket (2) is fixed with a stator (3), and the bracket (2) is supported inside the sealed housing (1) according to a spring (2s). A crankshaft (5) is installed through the center of the bracket (2), and a rotor (4) is installed on the crankshaft (5), and rotates together with the crankshaft (5) by utilizing the electric field interaction with the stator (3). An eccentric portion (5b) is formed on the upper end of the crankshaft (5), and a counterweight (5c) is formed in the opposite direction of the eccentric portion (5b), and an oil passage (5d) is formed ins...
