Abstract

The technical subject of the present invention is to solve the problems of the conventional compressors as described above, and to provide a refrigerator that does not have a cycle matching function or a refrigerator that does not include a control unit, and the compressor itself can control the drive of the linear motor. Compressor and its control method. In the compressor provided in the equipment including the refrigerant cycle disclosed in this specification to solve the above-mentioned problems, it is characterized in that the piston reciprocates inside the cylinder; and the linear motor is provided for driving the piston. a driving force to perform motion; a sensing part that senses a motor current of the linear motor; and a compressor control part that detects a load related to the device separately from the control part that controls the main body of the device. information, the compressor control unit calculates the phase difference between the stroke of the piston and the sensed motor current, compares the calculated phase difference with the reference phase difference value, and according to the comparison result, corresponds to the detected The load controls the driving of the linear motor.

Description

technical field [0001] The present invention relates to a compressor and a control method thereof, and more specifically, to a compressor that generates a control signal related to the drive of the compressor and controls a motor of the compressor, and a control method of the compressor. Background technique [0002] A compressor is a device that converts mechanical energy into compression energy of a compressed fluid, and is generally used, for example, in refrigeration equipment that is a part of a refrigerator or an air conditioner. [0003] Compressors are broadly classified into reciprocating compressors, rotary compressors, and scroll compressors. In a reciprocating compressor, a compression space capable of sucking or discharging working gas is formed between the piston and the cylinder, thereby compressing the refrigerant while the piston performs linear reciprocating motion inside the cylinder. In a rotary compressor, a compression space for sucking or discharging ...
