Abstract: The present invention relates to a transverse flux reciprocating motor, and a reciprocating compressor having the same, the motor including a stator wound with a magnet coil, a mover inserted into the stator and coupled with a magnet having opposite magnetic poles in an orthogonal direction with respect to a magnetic flux generated by the magnet coil, and a magnetic resonance spring allowing the mover to perform a resonance motion with respect to the stator using force trying to move toward a side with low magnetic resistance between the stator and the mover, whereby the transverse flux reciprocating motor and the reciprocating compressor having the same can be reduced in size and weight and obtain high efficiency.
