Stator for linear compressor

Abstract

A stator for a linear compressor comprises a coil winding, in which a coil winds in a circumference direction and current flows; a bobbin set, which is wound with the coil winding and which insulates the coil winding; and a plurality of core blocks, which are arranged in a circumference direction of the bobbin set at predetermined intervals from an axial direction of the bobbin set, which is advantageously used for simplifying the manufacturing process, enhancing the clamping force, cutting an overall production cost, and reducing the size of a product incorporating the same.

Description

technical field [0001] The present invention generally relates to a stator for a linear compressor, and more particularly, to a stator for a linear compressor that contributes to simplifying a manufacturing process and enhancing bonding force between assembled components. Background technique [0002] Generally, a reciprocating compressor is designed to form a compression space between a piston and a cylinder, into which working gas can be sucked into or discharged from the compression space, and a piston linearly reciprocating within the cylinder to compress refrigerant. [0003] Today, most reciprocating compressors have a part like a crankshaft to convert the rotational force of a driving motor into a linear reciprocating driving force of a piston, but there arises a problem of a huge mechanical loss due to such motion conversion. To solve this problem, the development of linear compressors is still ongoing. [0004] The linear compressor has a piston directly connected ...

Problems solved by technology

[0014] However, in the former case, when an injection-molded body is used for insulation between the coil and the core block, it is difficult to check whether the space is filled satisfactorily by the injection-molded body, and this difficulty often leads to a deterioration in performance reliability , increase in production costs and possible deformation after hardening of the injection-molded body, whereby post-processing is required later to ensure the air gap between the inner stator, outer stator and permanent magnets, which is disadvantageous in terms of mass production

[0015] On the other hand, in the case where the coil and the core pieces are separated from each other by a certain distance for insulation, the overall size of the linear motor increases, and further, the size of the linear compressor using the motor also increases.
