Abstract

The invention discloses a linear compressor and a control method thereof. The linear compressor comprises a housing, as well as a compressor body structure and a motor structure which are arranged in the housing, wherein the compressor body structure comprises a cylinder, a piston, resonant springs and a discharge valve plate arranged on the cylinder; the motor structure comprises a rotor, an outer stator and an inner stator; a first permanent magnet and a second permanent magnet are arranged on the rotor at an interval; the inner stator is U-shaped; a first coil and a second coil are correspondingly arranged on the inner stator; the outer stator and the inner stator adopt an integral structure, form a surrounding structure on the side of the cylinder and form a rotor inserting gap on the side of the rotor; and the resonant springs are mounted between the inner stator and the rotor and also between the rotor and a rear baffle. According to the linear compressor, when one of the coils is electrified to work, the other coil can be either electrified or not, so that the problems of motor efficiency reduction, coil heating and permanent magnet demagnetization due to the reason that the current of a single-coil motor is improved to correspond to a high-load working condition are solved.

Description

technical field [0001] The invention relates to the technical field of linear compressor refrigeration, in particular to a linear compressor and a control method thereof. Background technique [0002] In refrigeration technology, linear compressors are usually used for refrigeration at present, but the motor structure of existing linear compressors generally uses a set of coils, and when a set of coil structure motors is used to deal with high-temperature environmental conditions, it generally increases the current value To cope with high load conditions, this will cause problems such as reduced motor efficiency, coil heating, and permanent magnet demagnetization. Contents of the invention [0003] The purpose of the present invention is to overcome the above defects and provide a linear compressor and its control method, the linear compressor by changing the number of energized coil groups to deal with the refrigeration system and the ambient temperature of the compressor...
