Abstract
Disclosed is a structure for fixing a motor stator of a reciprocating compressor, the reciprocating compressor comprising: a frame unit mounted in a casing and elastically supported; a reciprocating motor including an outer stator coupled to the frame unit, an inner stator inserted into the outer stator, and a mover inserted between the outer stator and the inner stator; and a compression unit for compressing a refrigerant by receiving a linear-reciprocation driving force of the reciprocating motor, wherein the inner stator and the frame unit contacting the inner stator are coupled to each other by welding. According to this, the structure is simplified and a fabrication cost is reduced by facilitating a fabrication.
