    Abstract: A linear compressor includes one spring assembly including a plurality of spring parts fixed to both side surfaces of a supporter and a rear cover and configured to support a load generated in the compressor. In addition, both side portions of the spring part are provided with fixing brackets coupled to the supporter and the rear cover, and the fixing bracket is provided with an insertion member or a bracket coupling member so that the coupling force of the spring part can be increased.

    Abstract: There is provided a linear motor and a linear compressor including the same. The linear motor includes a stator including an air gap, a coil provided in the stator, a mover for reciprocating in the air gap, and at least one magnet fixed to the stator. In the magnet, a length in a first direction that intersects a reciprocating direction of the mover is larger than a length in a second direction that is the reciprocating direction of the mover. Therefore, it is possible to maintain or improve motor efficiency by using an amount of use of a magnet while using a low-priced magnet.

    Abstract: A linear compressor includes a cylinder, a piston disposed in the cylinder and reciprocating along an axis of the cylinder, a stator core disposed outside the cylinder, a coil winding body that is disposed in the stator core and includes first to fourth coils that are spaced from each other in a circumferential direction, a mover connected to the piston and reciprocating along the axis by an electromagnetic interaction with the coil winding body, and a switch unit configured to connect the first and second coils and the third and fourth coils in series or in parallel depending on a magnitude of a load. The first and second coils are connected in series, and the third and fourth coils are connected in series. The first to fourth coils each have the same inductance.

    Abstract: A linear compressor includes a casing, a cylinder forming a compression chamber inside the casing, a piston reciprocating to compress a fluid of the compression chamber, a mover having a movable magnet and reciprocating on the basis of a predetermined reference position to drive the piston, and a stator generating a thrust pushing the mover in the reciprocating direction and a restoring force pushing the mover in a direction toward the reference position according to an interaction with the movable magnet, wherein the stator includes a mover air gap formed to accommodate the mover and a magnetoresistive air gap formed in a position spaced apart from the mover air gap to change magnetic resistance of a magnetic circuit formed along the stator. According to this, a magnetic resonance spring with increased restoring force may be implemented.

    Abstract: A transverse flux reciprocating motor and a reciprocating compressor including a transverse flux reciprocating motor are provided. The transverse flux reciprocating motor may include a stator having an inner stator and an outer stator located outside and spaced apart from the inner stator in a radial direction, at least one magnet coil wound on the stator, at least one magnet coupled to an outer circumferential surface of the inner stator or an inner circumferential surface of the outer stator and having different magnetic poles arranged in an orthogonal direction of flux generated by the magnet coil, and a mover inserted into a cavity formed between the inner stator and the outer stator, formed of a magnetic material and reciprocating with respect to the stator. A magnetic resonant spring for causing resonant motion of the mover with respect to the stator using a force moving to low magnetic resistance between the stator and the mover is implemented, thereby reducing a size and weight of the reciprocating motor and the reciprocating compressor including the reciprocating motor and obtaining higher efficiency.
