Abstract: A transverse flux type reciprocating motor and a reciprocating compressor having a transverse flux type reciprocating motor are provided. The transverse flux type reciprocating motor may include a first reciprocating module including a first stator and a first rotor that reciprocates with respect to the first stator, a second reciprocating module including a second stator disposed to be spaced apart from the first stator in parallel to an axial direction and a second rotor that reciprocates with respect to the second rotor in the axial direction, and a connection member that connects side surfaces, which face each other, of the first rotor and the second rotors to each other. Thus, a magnetic resonance spring for allowing the rotor to be resonant with respect to the stator may be realized by using a force that moves to a side at which magnetic resistance is low between the stator and the rotor.

Abstract: A linear compressor is disclosed. The linear compressor comprises a frame, an outer stator comprising a stator core disposed at the frame, a teeth portion that extends inward from the stator core, and a teeth shoe that extends in a circumferential direction from an inner end of the teeth portion, a coil disposed at the teeth portion, a cylinder disposed at the frame, a piston disposed in the cylinder, an inner stator coupled to an outer circumferential surface of the piston and configured to reciprocate axially based on an electromagnetic interaction with the coil, a magnet that is disposed at the teeth shoe and faces the inner stator, and a virtual pole that is disposed at the teeth shoe and faces the inner stator, the virtual pole being disposed at an axial front or an axial rear of the magnet. The outer stator comprises a plurality of core plates stacked axially. A distance between the magnet and the inner stator is different from a distance between the virtual pole and the inner stator.
