Problems solved by technology

[0021] However, in the type in which the coil is wound on the inner lamination, the heat generated during the welding process is transferred to the pure iron sheet, and this heat transfer causes the pure iron sheet to elongate unevenly.
Therefore, the gap between the inner lamination and the outer lamination will expand, thereby reducing the efficiency of the motor and also causing errors in the assembly process
[0022] In addition, since the coil wound on the inner lamination is placed between the inner lamination and the magnetic gate, when the magnetic gate contacts the wire when the magnet reciprocates, the wire will be damaged.

Embodiment Construction

[0049] Figure 10A and Figure 10B Shown in the lamination device of the linear compressor according to the present invention, wherein the lamination 100 has many pure iron sheets arranged along the radial direction. Figure 11A and Figure 11B It shows the lamination device of the present invention, wherein the lamination 100 is fixed by the upper fixing member 130 .

[0050] Specifically, protruding portions 120 are formed on concentric circles of pure iron sheets arranged in the radial direction, and caulking grooves 120a are formed on each protruding portion.

[0051] An upper fixing member 130 made of a non-magnetic material or a material having high electrical resistance is filled in the caulking groove 120a of each protruding portion 120 .

[0052] In addition, if Figure 12 As shown, the fastener on one side of the lamination 100 supported by an inner coil spring (not shown in the figure) can be made into a lower fastener 200, the fixing ring 200a of the lower fasten...

Abstract

The present invention relates to a linear motor for a linear compressor that improves efficiency of a motor and simplifies a assembling process for a lamination by which the lamination is fixed by a fixing ring not by a welding process and lead wires are securely disposed. In a linear motor for a linear compressor, wherein there are an outer lamination and an inner lamination which is wound by a coil connect to lead wires and supported by inner coil springs, the linear motor also includes: a lamination wherein protruding portions respectively having a caulking groove are formed at concentric circles of radially arrayed iron pieces; and a non-magnetic fixing ring caulked in the caulking groove for preventing the iron pieces from being loosened.

Description

technical field [0001] The present invention relates to a linear compressor, and more particularly, to a linear motor structure of the linear compressor which improves the efficiency of the motor and easily assembles laminations provided in the linear motor. Background of the invention [0002] figure 1 It is an ordinary linear compressor. As shown, inside the sealed outer case 10 is a cylindrical inner case 20 having a predetermined inner space. [0003] A circle of cylindrical outer laminations 30 is fixed on the inner wall of the inner casing 20, a disk-shaped cover plate 40 with a hole in the center is connected to the upper end of the inner casing 20, and a disk-shaped cover 50 is connected to the inner casing lower part of the . [0004] The upper portion of a cylinder 60 passes through the hole in the central portion of the cover plate 40, and a valve device 70 connected to the central upper portion of the above-mentioned cylinder 60 tightly covers the hole through...
