Patent ID: 8382455

Claim:
A linear compressor that makes a reciprocating motion, comprising a movable member including a piston, a cylinder, a fixed member including a motor provided to the cylinder to make the piston reciprocate, one or more springs, a part of which is fixed to the movable member and another part of which is fixed to the fixed member so as to provide the movable member with a drive power to move from a first point to a second point, and a shell configured to house the movable member, the fixed member, and the one or more springs, wherein the motor comprises: an inner stator comprising a plurality of core blocks insulatively laminated in a circumferential direction; an outer stator that surrounds the inner stator with a predetermined spacing therebetween and including a coil winding, in which a coil is wound in a circumferential direction and current flows, first and second injection-molded bodies which are wound with the coil winding in an axial direction, that insulate the coil winding, and a plurality of core blocks coupled to the first and second injection-molded bodies; and one or more permanent magnets that maintain an air-gap between the inner stator and the outer stator and linearly reciprocate by an interactive electromagnetic force, wherein the first and second injection-molded bodies each includes a plurality of positioning devices formed in the circumferential direction at predetermined intervals to have the plurality of core blocks settled thereon, and wherein each of the plurality of positioning devices comprises an assembly guide that protrudes over at least one of both axial ends or outer contour faces of the first and second injection-molded bodies and that comes in contact with both ends of the plurality of core blocks in the circumferential direction.
