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.
