Abstract: A linear compressor and a linear motor for a linear compressor are provided. The linear motor may include a first stator, a second stator spaced apart from the first stator, and at least one permanent magnet disposed between the first stator and the second stator. The first stator may include a bobbin around which a coil may be wound, and a plurality of core blocks that surrounds the bobbin. In at least one core block of the plurality of core blocks, a distance between a first surface that faces the second stator and a second surface of the second stator that faces the first surface varies in a circumferential direction of the second stator.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape, a shell cover that covers both open ends of the shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a piston that reciprocates within the cylinder in an axial direction to compress the refrigerant within the compression space, a motor assembly including a motor that provides power to the piston and a stator cover that supports the motor, and resonant springs seated on the stator cover that support the piston to allow the piston to perform a resonant motion. The resonant springs may be circularly arranged at three points having a same interval around a center in an axial direction.

Abstract: A linear compressor and a linear motor are provided. The linear motor may include a first stator, a second stator spaced apart from the first stator, and a permanent magnet disposed to be movable in a first direction between the first and second stators. The first stator may include a bobbin with a coil wound thereon, and a stator core that surrounds the bobbin. The stator core may be located between the second stator and the coil and may include first and second magnetic poles spaced apart from each other. One portion or entire portions of each of the first and second magnetic poles may have a constant magnetic path width within a range of a movement trajectory of the permanent magnet.

Abstract: A linear compressor is provided. The linear compressor may include a suction valve with a plurality of wings. Each of the plurality of wings may include two first edge portions that extend in an outer direction of a fixing portion, and a second edge portion forming an outer circumferential portion of the wing. A distance between a first edge portion of a first wing among the plurality of wings and a second edge portion of a second wing among the plurality of wings gradually increases toward the outer direction of the suction valve.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a refrigerant inlet, a cylinder provided inside the shell, a piston that reciprocates inside the cylinder to compress a refrigerant, a motor assembly that provides a drive force to the piston, and a magnet assembly that delivers the drive force to the piston. The magnet assembly may include a magnet frame having a cylindrical shape. A permanent magnet may be installed in or on the magnet frame. A coupling plate may be coupled to a side of the magnet frame and may include a flange coupled to an end portion of the permanent magnet.
