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.
