摘要： PURPOSE: An electric current limit algorithm of a linear compressor is provided to reduce the size of a motor by applying an electric current limit algorithm to an overload. CONSTITUTION: A microcomputer checks generation of an electric current limit if the temperature of external air is higher than 37deg.C. At an overload, an electric current limit of 2.2A per 1/60sec is generated from a refrigerator. In no generation of an electric current limit, a 1min electric current limit flag is set as 0 and time starts to be counted. In 1min, the 1min is saved in a count and the stroke command is compared with the top limit of 20mm. If the stroke command is larger than 20mm, the stroke command is set as 20mm. Otherwise, the stroke is increased about 0.2mm up to the top limit. If the electric current limit is generated, the 1min electric current limit flag is set as 1. Then, the stroke command is compared with the bottom limit of 18mm. If the stroke command is larger than 18mm, the stroke command is decreased about 0.2mm to the bottom limit. The stroke is run at 20mm in generation of an electric current limit or at 18mm by reduction of 0.2mm per 1/60sec. The stroke of a piston is operated between the bottom limit of 18mm and the top limit of 20mm to prevent an overload.

CONSTITUTION: A clearance volume adjusting apparatus using a speed sensorless control of a linear compressor includes a knock sensor (80) attached to the linear compressor for detecting whether a piston and a discharge valve in the compressor collide thereby outputting a frequency based on the detection result, a high-pass filter (90) for high-pass filtering the frequency output from the knock sensor (80), a rectifier (100) for rectifying the high-pass filtered frequency, a peak detecting portion (101) for detecting a peak value of the frequency through the rectifier (100), a micro computer (70) for controlling the top clearance volume with a peak value of a present speed or a speed command value based on the detected peak value of the frequency through the peak detecting portion (101). The clearance volume adjusting apparatus determines whether the piston and the discharge valve of the compressor collide using high frequency component generated upon colliding and controls the speed of the compressor by comparing the peak value of the current speed and the speed command value when the collision occurs, thereby compensating the speed calculating error due to variations in temperature, pressure and driving. The clearance volume adjusting apparatus can reduce noise by adjusting the top clearance volume according to the determination on the collision.
