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 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.
