Abstract: A moving core type reciprocating motor is provided that may include a stator on which a coil may be wound and having an air gap; a magnet fixed to the stator; and a mover that includes a moving core disposed to face the magnet in the air gap and reciprocates with respect to the stator. The magnet may have a first pole and a second pole that are different poles arranged in a reciprocation direction of the mover, and a length of the first pole may be larger than a length of the second pole.
