Abstract: A linear compressor is provided. The linear compressor includes a stator, a mover, a compression instrument coupled to the mover and including a cylinder and a piston, and a nonmagnetic conductor which generates a reaction flux to disturb the flow of a leakage flux as an induced flux is generated by the leakage flux through the compression instrument. The linear compressor minimizes leakage flux to the compression instrument to increase efficiency output power of the compressor.

Abstract: An apparatus and a method for controlling an operation of a compressor capable of preventing an under stroke or an overstroke of a compressor, occurring due to a variation value of a power voltage applied to a motor of the compressor includes a control unit outputting a selection signal according to a variation value of a power voltage applied to the motor of the compressor; capacitors connected to the motor; and a switching unit selectively varying capacitance of the capacitors based on the selection signal.

Abstract: A linear compressor and a method for controlling the same. The linear compressor automatically short-circuits part of a coil having no power-supply voltage in order to substantially prevent an excessive stroke from being generated when the linear compressor is initially operated. The linear compressor includes a piston contained in a cylinder, for executing reciprocating linear motion to suck or discharge a refrigerant, a linear motor for providing the piston with driving power to allow the piston to execute the reciprocating motion, and a power-supply unit for providing the linear motor with a power-supply voltage, and performing an automatic short-circuit function to prevent an excessive stroke from being generated during an initial operation stage of the linear motor. Therefore, the linear compressor can reduce noise caused by the excessive stroke generated during the initial operation stage of the linear compressor, resulting in increased efficiency and convenience of the linear compressor.
