Abstract
There is provided a linear motor and a linear compressor including the same. The linear motor includes a stator including an air gap, a coil provided in the stator, a mover for reciprocating in the air gap, and at least one magnet fixed to the stator. In the magnet, a length in a first direction that intersects a reciprocating direction of the mover is larger than a length in a second direction that is the reciprocating direction of the mover. Therefore, it is possible to maintain or improve motor efficiency by using an amount of use of a magnet while using a low-priced magnet.
