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。
