Abstract

The invention provides a linear compressor and a linear motor. The linear motor includes a first stator, a second stator spaced apart from the first stator; and a permanent magnet disposed to be movable in a first direction between the first and second stators. The first stator includes a bobbin with a coil wound thereon, and a stator core surrounding the bobbin. The stator core is located between the second stator and the coil and includes first and second magnetic poles spaced apart from each other. One portion or entire portions of each of the first and second magnetic poles have a constant magnetic path width within a range of a movement trajectory of the permanent magnet.

Description

technical field

[0001] The invention relates to a linear compressor and a linear motor. Background technique

[0002] Generally speaking, a compressor (Compressor) is a mechanical device that receives power from a power generating device such as an electric motor or a turbine and compresses air or refrigerant or other various working gases to increase the pressure. It is widely used in refrigerators and air conditioners. Classes of home appliances or entire industries.

[0003] If this kind of compressor is classified, it can be divided into: a compression space for sucking and discharging working gas is formed between the piston (Piston) and the cylinder (Cylinder), and the piston performs linear reciprocating motion inside the cylinder while A reciprocating compressor (Reciprocating compressor) that compresses the refrigerant; a compression space for sucking and discharging working gas is formed between the eccentrically rotating roller (Roller) and the cylinder, and the ...
