摘要： A linear compressor (100) comprises: a cylinder (120); a piston (110) reciprocated within the cylinder (120) in an axial direction; and a linear motor (200) that provides power to the piston (120). The linear motor (120) comprises: a first stator (210); a second stator (250) spaced apart from the first stator (210); and at least one permanent magnet (260) disposed between the first stator (210) and the second stator (250), wherein the first stator (210) comprises: a bobbin (240) around which a coil (246) is wound; and a plurality of core blocks (211) that surrounds the bobbin (240). In at least one core block of the plurality of core blocks (211), a distance between a first surface (214a) that faces the second stator (250) and a second surface (251) of the second stator (250) that faces the first surface (214a) varies in a circumferential direction of the second stator (250).
