A linear compressor having an electromagnet; an oscillating body movably guided in an oscillating fashion in the alternating field of the electromagnet; a cylinder; a piston connected to the oscillating body and movable back and forth inside the cylinder; a power supply circuit to supply the electromagnet with an alternating current; a proximity sensor to detect whether a distance between the piston and the end face of the cylinder falls below a predetermined threshold value; and a control circuit to detect a time period in which the distance between the piston and the end face of the cylinder falls below the threshold value and to regulate an amplitude and/or a phase of the alternating current if the time period deviates from a positive setpoint value.
