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 compressor according to the present disclosure may include a bearing member located out of a range in an axial direction of a rotor. Accordingly, the bearing member and the rotor cannot overlap each other so as to reduce a bearing area. This may result in reducing a frictional loss of the compressor and ensuring a press-fit length of the rotor, so as to prevent interference between the rotor and a stator. Also, an area of an oil passage can be increased without an increase in the frictional loss, resulting in an increase in an amount of oil supplied.

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.

Abstract translation: 根据本公开的压缩机可以包括位于转子的轴向范围之外的轴承构件。 因此，轴承构件和转子不能相互重叠，以减小承载面积。 这可能导致减小压缩机的摩擦损失并确保转子的压入长度，以防止转子和定子之间的干扰。 此外，可以增加油路的面积而不增加摩擦损失，导致供油量的增加。
