    摘要: The present invention discloses a linear compressor in which a piston is driven by a linear motor and linearly reciprocated inside a cylinder to suck, compress and discharge refrigerants. The linear compressor synchronizes an operation frequency of the linear motor with a natural frequency of the piston, considering that an elastic force of a mechanical spring and a gas spring which elastically support the piston in the motion direction is varied by load. Even if the load is varied, the linear motor is operated in the resonance state, to maximize efficiency. The linear compressor varies a stroke of the piston according to the load, thereby actively handling and rapidly overcoming the load and reducing power consumption.
