Linear motor and linear compressor having same

A linear motor, comprising:

• a stator, wherein a winding coil is provided on the stator and a plurality of magnets is coupled to the stator;
• and
• a mover spaced apart from the stator to reciprocate with respect to the stator, the mover having a mover core made of a magnetic material instead of a permanent magnet, wherein the plurality of magnets is magnetized in a same direction, wherein a fixing groove is formed on an outer circumferential surface of the stator, wherein a portion of a fixing member is inserted into the fixing groove to be supported in an axial direction, wherein at least one of the plurality of magnets is supported in the axial direction by the fixing member, wherein the mover is spaced in a radial direction from the stator to be provided with a plurality of air gaps spaced in the axial direction between the stator and the mover, wherein the stator is provided with pole portions on both ends in a reciprocating direction, respectively, and fixed-side core protrusions extending from each of the pole portions toward the mover are formed, respectively, wherein the plurality of magnets is respectively coupled to one side of each of the fixed-side core protrusions in the axial direction, wherein each fixed-side core protrusion is formed to be eccentric toward a center of the stator at both ends of the pole portion, wherein the plurality of magnets is coupled to be supported on outer surfaces of the fixed-side core protrusions, respectively, and wherein a sum of lengths of the fixed-side core protrusions and the plurality of magnets in the axial direction, located on both sides based on the stator center, respectively, are equal to each other.
