ABSTRACT:
A linear compressor having a reciprocating piston, a linear motor driving the piston, and a motor controller to vary magnitude of a stroke of the piston according to power, including: a near-collision detector detecting whether the piston passes a near-collision position spaced from a top dead center according to a predetermined high power with a predetermined high power distance; and a collision return time calculator calculating a near-collision position return time taking for the piston to return to the near-collision position on a basis of the detection of the near-collision detector according to compression and expansion cycles, and wherein the motor controller decreases a driving force of the linear motor if the near-collision position return time is greater than a predetermined allowance time per power, and increases the driving force of the linear motor if the near-collision position return time is less than the predetermined allowance time per power.
