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.
