Abstract: A reciprocating motor and a reciprocating compressor having a reciprocating motor are provided. The reciprocating motor may include a stator having a magnet coil, provided with an air gap respectively formed at both sides in an axial direction by interposing the magnet coil therebetween; a mover inserted into the stator, reciprocating with respect to the stator as at least one magnet is arranged at any one of the air gaps formed at both sides and a non-magnet is arranged at the other one of the air gaps; and a magnetic resonance spring that resonates the mover with respect to the stator using a force for moving toward low magnetic resistance between the mover and the stator. The reciprocating motor and the reciprocating compressor having a reciprocating motor may be downsized and lightweight, and may obtain high efficiency.

Abstract: A transverse flux reciprocating motor and a reciprocating compressor including a transverse flux reciprocating motor are provided. The transverse flux reciprocating motor may include a stator having an inner stator and an outer stator located outside and spaced apart from the inner stator in a radial direction, at least one magnet coil wound on the stator, at least one magnet coupled to an outer circumferential surface of the inner stator or an inner circumferential surface of the outer stator and having different magnetic poles arranged in an orthogonal direction of flux generated by the magnet coil, and a mover inserted into a cavity formed between the inner stator and the outer stator, formed of a magnetic material and reciprocating with respect to the stator. A magnetic resonant spring for causing resonant motion of the mover with respect to the stator using a force moving to low magnetic resistance between the stator and the mover is implemented, thereby reducing a size and weight of the reciprocating motor and the reciprocating compressor including the reciprocating motor and obtaining higher efficiency.
