In a reciprocating compressor including a first frame for supporting a
cylinder of a compressing unit, a second frame for supporting a side of an
outer stator of a motor unit and a third frame for supporting the other
side of the outer stator and an inner stator of the motor unit, wherein
the motor unit is arranged between the second and third frames, they are
combined with each other, and the assembly is combined with the first
frame. Accordingly, a reciprocating compressor is capable of reducing a
fabrication cost by eliminating precise processing of construction parts
and simplifying an assembly process by constructing a reciprocating motor
as one assembly and combining it with a compressing unit.
