The invention relates to an active vibration damping device for a linear compressor. The active vibration damping device for the linear compressor comprises an active vibration damping assembly connected with the linear compressor. The active vibration damping assembly comprises a driving motor, an upper leaf spring assembly and a lower leaf spring assembly, wherein the upper leaf spring assemblyand the lower leaf spring assembly are separately installed at the upper end and lower end of the driving motor. The driving motor comprises a motor shaft, a stator assembly and a promoter assembly which are sequentially arranged from inside to outside. The stator assembly comprises an inner magnetic pole and a coil assembly arranged on the outer peripheral wall of the inner magnetic pole in an embedded mode. The promoter assembly comprises an outer magnetic pole and magnetic steel installed on the inner peripheral wall of the outer magnetic pole. The motor shaft sequentially penetrates through the lower leaf spring assembly, the inner magnetic pole and the upper leaf spring assembly and then is connected to the tail of the linear compressor. The problem of large axial mechanical vibrationin the operation process of the linear compressor in the prior art is solved, and the wide application of the linear compressor is achieved.
Description
technical field [0001] The invention relates to the technical field of linear compressors, in particular to an active damping device for linear compressors. Background technique [0002] Linear compressors have the advantages of large capacity, high pressure, low noise, high efficiency and high reliability, and have broad application prospects in military, civil and aerospace and other related fields. Since the linear compressor mostly adopts the structural characteristics of a single piston, it determines that there is a problem of large axial vibration during the reciprocating motion of the piston. The vibration problem will cause box resonance and system noise amplification, especially in the optical lens and infrared fields. Problems such as image instability may occur. The vibration problem is the biggest bottleneck restricting the application and development of linear compressors, which will make it unable to meet the vibration-sensitive technical fields. Therefore, ...
