Abstract: A linear compressor includes a cylinder defining a compression space for a refrigerant, a piston reciprocated in an axis direction within the cylinder, and a linear motor providing power to the piston. The linear motor includes an inner stator disposed outside the cylinder, the inner stator including a center core and a side core disposed on at least one side of the center core, an outer stator disposed to be spaced outward from the inner stator in a radius direction, a permanent magnet movably disposed in an air gap defined between the inner stator and the outer stator, and a deformation prevention device for preventing the inner stator from being deformed.

Abstract: A compressor includes a first scroll and a second scroll engaged with the first scroll for performing an orbiting motion relative to the first scroll to form a compression chamber along with the first scroll. A stator is disposed at one side of the second scroll and includes a stator core. A rotor is rotatably disposed inside the stator core, and includes a rotor core. A rotary shaft has one end portion eccentrically coupled to the second scroll and the other end portion coupled to the rotor core. The rotor core is formed with at least one space portion axially recessed into the rotor core.

Abstract: Provided is a linear compressor. The linear compressor includes a cylinder defining a compression space for a refrigerant, a piston reciprocated in an axis direction within the cylinder, and a linear motor providing power to the piston. The linear motor includes an inner stator disposed outside the cylinder, the inner stator including a center core and a side core disposed on at least one side of the center core, an outer stator disposed to be spaced outward from the inner stator in a radius direction, and a magnet movably disposed in an airgap defined between the inner stator and the outer stator. The side core includes a core body and a lead-out guide device coupled to the core body to expose or lead out a power line to the outside of the side core.

Abstract: 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.

Abstract translation: 提供了一种用于压缩机的电动机和具有该电动机的往复式压缩机。 绕组线圈可以通过从绕组线圈上除去线轴而形成，然后在绕组线圈的外圆周表面上涂覆绝缘材料，以使得由绕组线圈产生的热量和湿气被发射到外部并提供增强的性能 和可靠性。 当线圈从绕组线圈移除时，线圈线可以卷绕在绕线筒的去除部分上，以通过线圈线在相同的面积上提高占空比，从而提高电动机的效率。 可以将弹性构件或粘合剂插入或施加到绕组线圈和内定子的线圈插入槽之间的空间中以最小化线圈线的振动。 当自粘接材料熔化时，线圈线被粘附，形成粉末形式的绝缘材料可以熔化，形成涂层。 因此，可以容易地制造绕组线圈，并且可以减小绕组线圈的制造成本。
