Technical field

The present invention relates to Compressor Technology fields, more particularly to a kind of stator and compressor.

Background technique

For air-conditioning products, in addition to valuing refrigeration effect, noise is also the key for assessing a product, the production of noise The raw serious experience for affecting user.During operation of air conditioner, the reason of generating noise, mainly has mechanical noise, air dynamic Power noise and electromagnetic noise etc., wherein electromagnetic noise is the electromagnetism generated in the process of running by the driving motor of compressor What harmonic wave was motivated, electromagnetic force shakes stator, is transmitted on shell through stator outer surface, causes shell in varying degrees Vibration;Dispenser connected to the housing is transmitted by motor oscillating, and dispenser shell, than relatively thin, radiating surface is bigger, Therefore since 6 multiple-frequency vibrations that motor generates are also apparent from dispenser.

In compressor assembling process, stator and shell using being interference fitted, shell act on the enclasping force of stator for The circularity of stator inner circle can generate certain influence, to cause motor gas-gap Magnetic field inhomogeneity, radial electromagnetic force increases, thus Keep noise effect very severe, thorax phenomenon is swept into generation when serious, or even stator inner circle is made locally to generate high temperature, keeps slot interior insulation burnt Crisp failure causes winding earth or short circuit.

It can be seen that the high noise that compressor generates has inseparable relationship with motor, it is big to reduce compressor noise Body is divided into three classes: 1, reducing the noise of driving source, need to sacrifice partial properties for motor to reach noise requirements;2, Weaken from vibration transfer path, weakens energy;3, recipient is protected.In contrast, the first and the third side The work in face wants difficult compared to second method, thus at present the method for most of reduction compressor electric motor noises be all from Start on transmission path.
