Abstract

There is disclosed a compressor comprising a case comprising a discharging part provided one side and configured to discharge a refrigerant, the case defining a predetermined space for storing oil; a drive part comprising a rotor coupled to an inner circumferential surface of the case and having coils wound there around and configured to generate a rotation magnetic field, and a rotor mounted in the rotor and configured to be rotatable by the rotation magnetic field; a shaft extending in a state of being coupled to the rotor; a compression part lubricated by the oil in a state of being coupled to the shaft and configured to compress and discharge the refrigerant; and a sealing part extending from the stator towards the compression part and configured to induce the winding of the coil.
