Abstract
A linear compressor and a linear motor are provided. The linear motor may include a first stator, a second stator spaced apart from the first stator, and a permanent magnet disposed to be movable in a first direction between the first and second stators. The first stator may include a bobbin with a coil wound thereon, and a stator core that surrounds the bobbin. The stator core may be located between the second stator and the coil and may include first and second magnetic poles spaced apart from each other. One portion or entire portions of each of the first and second magnetic poles may have a constant magnetic path width within a range of a movement trajectory of the permanent magnet.
