  • Reciprocating compressor
    Patent number: 7537438
    Abstract: A reciprocating compressor includes: a cylinder installed inside a casing and having a space therein; a piston disposed inside the cylinder; an inner stator fixed at an outer circumference of the cylinder; a magnet fixed at an outer circumference of the inner stator; and an outer stator disposed to maintain a certain distance from an outer circumference of the magnet. Accordingly, the number of components is reduced thus to reduce a manufacturing cost, and performance can be also improved.
    Type: Grant
    Filed: January 10, 2005
    Date of Patent: May 26, 2009
    Assignee: LG Electronics Inc.
    Inventors: Gye-Young Song, Kwang-Wook Kim, Je-Nam Kang
  • Reciprocating motor and reciprocating compressor having the same
    Patent number: 7075199
    Abstract: Disclosed are a reciprocating motor and a reciprocating compressor having the same. The reciprocating motor comprises: an outer stator; an inner stator arranged at an inner circumferential surface of the outer stator with an air gap and at which a winding coil is wound; and a magnet arranged between the outer stator and the inner stator and linearly-moved when a power is applied to the winding coil. The winding coil is installed at the inner stator thus to reduce a usage amount of the coil, thereby reducing a fabrication cost of a motor. Also, a resistance of the coil is reduced thereby to enhance an efficiency of the motor.
