ABSTRACT:
Disclosed herein is a linear compressor wherein a compression unit, including a cylinder and a linear motor, is supported by a frame mounted in a hermetic container. The frame is die cast using diamagnetic zinc having a high forming accuracy, thereby preventing an electromagnetic force of the linear motor from being leaked therethrough, and enabling a reduction in the number of machining times thereof after die casting.
