Transverse flux reciprocating motor and linear compressor including the same

A transverse flux reciprocating motor comprising:

• an outer stator comprising:
• a stator core comprising a plurality of core plates stacked in an axial direction,
• a teeth portion that extends from the stator core to an inside of the stator core, and
• a teeth shoe that extends from an inner end of the teeth portion in a circumferential direction of the stator core;
• a coil disposed at the teeth portion;
• an inner stator disposed in the outer stator and configured to reciprocate relative to the outer stator in the axial direction based on electromagnetic interaction with the coil;
• a magnet that is disposed at the teeth shoe and faces the inner stator;
• and
• a virtual pole disposed at the teeth shoe, the virtual pole facing the inner stator and being spaced apart from the magnet in the axial direction.

A linear compressor comprising:

• a frame;
• a cylinder disposed in the frame;
• a piston disposed in the cylinder;
• an outer stator disposed in the frame, the outer stator comprising:
• a stator core comprising a plurality of core plates stacked in an axial direction,
• a teeth portion that extends from the stator core to an inside of the stator core, and
• a teeth shoe that extends from an inner end of the teeth portion in a circumferential direction of the stator core;
• a coil disposed at the teeth portion;
• an inner stator coupled to the piston and configured to reciprocate relative to the outer stator in the axial direction based on electromagnetic interaction with the coil;
• and
• a magnet that is disposed at the teeth shoe and faces the inner stator, the magnet comprising a first magnet and a second magnet that are spaced apart from each other in the axial direction.

A linear compressor comprising:
