The moving core-type reciprocating motor includes a stator including an inner stator and an outer stator having one side connected to one side of the inner stator and the other side spaced apart from the other side of the inner stator in a radius direction to define a gap together with the other side of the inner stator, a magnet coil wound between the inner stator and the outer stator, a magnet fixed to at least one of the inner stator and the outer stator so as to be exposed to the gap, a rotor including a moving core disposed in the gas and made of a magnetic material to reciprocate with respect to the stator and the magnet and a hollow connection member made of a nonmagnetic material and supporting the moving core so that the moving core is exposed to the gap toward the magnet. Thus, the reciprocating motor and the reciprocating compressor having the same are compact and lightweight to more improve efficiency.

摘要： A transverse flux reciprocating motor and a reciprocating compressor having a transverse flux reciprocating motor are provided. The transverse flux reciprocating motor may include 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 that allows the mover to perform a resonance motion with respect to the stator using a 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 a transverse flux reciprocating motor may be reduced in size and weight and obtain high efficiency.

摘要： A motor for a compressor, and a reciprocating compressor having the same, are provided. A winding coil may be formed by removing a bobbin from the winding coil, and then coating an insulating material on an outer circumferential surface of the winding coil, to allow heat and moisture generated by the winding coil to be emitted to outside and provide enhanced performance and reliability. As a bobbin is removed from the winding coil, a coil line may be wound on the removed portion of the bobbin to enhance an occupation ratio by the coil line on the same area, and thus enhance efficiency of the motor. An elastic member or an adhesive may be inserted or applied into a space between the winding coil and a coil insertion groove of an inner stator to minimize vibrations of a coil line. The insulating material, which is in the form of powder, may melt while the coil line is adhered as the self-bonding material melts, forming a coating layer. Accordingly, the winding coil may be easily fabricated, and fabrication costs of the winding coil may be reduced.
