Abstract:
1. A reciprocating compressor comprising: a hermetic casing; a reciprocating motor arranged in the casing and generating a reciprocation force; a compression unit for compressing a fluid by receiving a reciprocation force from the reciprocating motor; and frames for supporting the reciprocating motor and the compression unit, wherein the reciprocating motor includes: an outer stator supported by the frames; an inner stator arranged at an inner circumferential surface of the outer stator with an air gap and at which a winding coil is wound; a magnet arranged between the outer stator and the inner stator and linearly-moved when a power is applied to the winding coil; and wherein the magnet is mounted at a magnet frame with the same interval, the magnet frame is connected to a piston of the compression unit, and a through hole for passing the resonance spring is formed at the magnet frame.
