LINEAR COMPRESSOR

WIPO Patent Application WO/2011/062428

A2

The present invention relates to a linear compressor, and particularly relates to a linear compressor capable of varying a natural cooling capacity while removing a capacitor connected to a motor. The linear compressor according to the invention comprises: a fixed member that includes a compression room formed therein; a movable member that compresses a sucked refrigerant into the compression room while linearly reciprocating inside the fixed member; at least one spring that is provided to elastically support the movable member in a movement direction of the movable member; a motor that is provided in connection with the movable member so as to linearly reciprocate the movable member in a shaft direction; a motor control unit that varies a cooling capacity through the reciprocation of the movable member corresponding to a load by controlling an AC voltage applied to the motor such that a stroke of the movable member is proportional to a magnitude of the AC voltage.
