Abstract

A linear compressor which can perform the natural cooling capacity modulation, even if a capacitor connected to a motor is removed. The linear compressor includes a fixed member having a compression space therein, a movable member linearly reciprocated in the fixed member to compress a refrigerant sucked into the compression space, and one or more springs provided to elastically support the movable member in the motion direction of the movable member. The compressor also includes a motor connected to the movable member to linearly reciprocate the movable member in the axial direction, and a motor control unit performing the cooling capacity modulation by the reciprocation of the movable member according to a load, by controlling an AC voltage applied to the motor so that a stroke of the movable member can be proportional to the magnitude of the AC voltage applied to the motor.
