There are provided a linear motor and the linear compressor using the linear motor. The linear motor includes a bobbin, a coil wound in the bobbin, an outer core provided on the bobbin, an inner core provided to perform a linear reciprocating motion with a moving body, and a magnet provided on the inner core so that the inner core and the moving body perform a linear reciprocating motion. The magnet is configured to provide a gap between the magnet and an outer core and to be in close contact to the inner core.

Linear motor and linear compressor using the same

A motor structure for a reciprocating compressor, by which an power lowering of the motor can be prevented by installing a magnet to be eccentric toward a direction compressing a fluid to compensate a backward moved amount of the magnet by compression pressure during operating the compressor and a motor saturation can be prevented, comprises: an outer core of cylindrical shape fixed inside a sealed chamber and including a winding coil wound therein; an inner core disposed on an inner circumferential surface of the outer core with a predetermined gap for forming a flux with the outer core when an electric source is applied to the winding coil; and a magnet disposed between the outer core and the inner core so as to move linearly for making a piston to perform a linear reciprocating movement, wherein an initial mid position of the magnet is located to be eccentric as a predetermined distance from a mid position of the outer core and of the inner core toward a moving direction of the piston when a fluid is compressed.

Motor structure for reciprocating compressor

A linear compressor includes a casing having a suction pipe and a discharge pipe and a unit including a cylinder formed therein and an inner stator assembly and an outer stator assembly installed on the exterior of the cylinder and a magnet assembly inserted into the certain void of the inner and outer stator assembly for performing a reciprocating motion linearly and a piston connected to the magnet assembly by forming a connection portion and a gas through hole formed in the connection portion of the magnet assembly and piston, which is capable of decreasing a flow resistance by forming the gas through holes in the connection portion of the magnet assembly and the piston and decreasing the specific volume of the suction coolant by making the coolant gas filled the both area of the connection portion flow reciprocally in the reciprocating motion of the piston.

A magnet fixed structure for a compressor motor, which includes a cylindrical magnet paddle in which a plurality of magnet insertion holes are formed along a circumference thereof or a cylindrical magnet paddle alone, a plurality of magnets inserted into the magnet insertion holes of the magnet paddle or fixed to the magnet paddle, and a magnet fixing ring or a varnish-type molding member for fixing the magnets, effectively fixes the magnets to the magnet paddle, for thereby improving reliability and efficiency of the compressor motor as well as mass-productivity thereof.

Magnet fixed structure for compressor motor

A linear compressor includes a piston that is slidably mounted in a cylinder. An hermetic spring holder has an end portion which is connected to a corresponding portion of the cylinder and which surrounds the cylinder while being located at a predetermined distance therefrom. A cap is fixedly connected to another end portion of the hermetic spring holder. A refrigerant suction guide tube is inserted from a refrigerant suction side into the piston. A spring supports the piston. The compressor causes refrigerant gas to flow solely through the refrigerant suction tube so that the internal refrigerant gas flow path of the piston is larger and the structure simpler. Thereby, damage to the path is decreased, the flow of refrigerant gas is more smooth and heat generated in the heated piston is blocked from being transferred to the refrigerant gas.
