Abstract
An outer stator of a reciprocating compressor comprises: a bobbin formed as a ring shape and provided with a winding coil therein; an outer stator frame coupled to an outer circumferential surface of the bobbin and formed of a magnetic body in which a flux flows; a plurality of first core blocks coupled to the outer stator frame and positioned radially at one side of the bobbin; and a plurality of second core blocks coupled to the outer stator frame, facing the first core blocks, and positioned at the other side of the bobbin. Accordingly, deformation which may occur during manufacturing can be prevented, and a size of a motor can be minimized.
