Abstract
A linear compressor includes a casing, a cylinder forming a compression chamber inside the casing, a piston reciprocating to compress a fluid of the compression chamber, a mover having a movable magnet and reciprocating on the basis of a predetermined reference position to drive the piston, and a stator generating a thrust pushing the mover in the reciprocating direction and a restoring force pushing the mover in a direction toward the reference position according to an interaction with the movable magnet, wherein the stator includes a mover air gap formed to accommodate the mover and a magnetoresistive air gap formed in a position spaced apart from the mover air gap to change magnetic resistance of a magnetic circuit formed along the stator. According to this, a magnetic resonance spring with increased restoring force may be implemented.
