Abstract
A rotary compressor adopts the structure that a motor and a compressing mechanism are arranged in a housing, wherein the motor comprises a rotor and a stator; the rotor comprises a rotor core which is formed by laminating a plurality of rotor sheets, and permanent magnets which are arranged in the rotor core and twisted in the axis direction of the motor at a certain angle; the rotor core is twisted at the same angle as that of the permanent magnets so as to accommodate the permanent magnets in an embedded manner; and the twisting angle Alpha of the permanent magnets ranges from 1 degree to 30 degrees, wherein the Alpha is the maximal torsional angle of the two end surfaces of each permanent magnet which is rectangular or magnetic shoe-shaped and is magnetized radially or parallelly. According to the rotary compressor provided by the utility model, the permanent magnets are twisted in the axis direction of the motor at a certain angle to have oblique poles, so that not only is the inductive voltage wave shape of a stator winding remarkably improved, but also the cogging torque is reduced, and the rotating torque pulsation and stray loss of the motor are reduced; and at the same time, the purposes of high efficiency, low vibration, low noise and stable operation of a compression system are achieved.
Description
Technical field
The utility model relates to a kind of rotary compressor.
Background technology
A big chunk in the noise of rotary compressor comes from the magneto as the compressor power source.And magneto causes vibrating noise also to strengthen, thereby influences the performance of whole compressor system because the influence of harmonic such as non-sineization of cogging torque and counter potential waveform can make the load torque pulsation increase.
In order to reduce harmonic wave, reduce noise vibration, people have proposed a lot of methods and measure.Wherein mainly comprise: adopt bread shape permanent magnet, skewed stator slot etc.Adopt bread formula permanent magnet to be primarily aimed at and paste the formula rotor structure, be not suitable for built-in structure in face; And the mode that adopts skewed stator slot can make the stator slot utilance reduce, and the coiling difficulty strengthens, and is unfavorable for that the technology of automation coiling realizes.
The utility model content
The purpose of the utility model aims to provide a kind of simple and reasonable, flexible operation, cogging torque is little, vibration is low, noise is low, torque pulsation is little, stray loss is little, the rotary compressor of operation high efficiency smooth, to overcome weak point of the prior art.
A kind of rotary compressor by this purpose design; Be provided with motor and compressing mechanism in the housing; Motor comprises rotor and stator, and rotor includes rotor core and the permanent magnet that is overrided to form by the multi-disc rotor punching, and its architectural feature is that permanent magnet is built in rotor core; Permanent magnet reverses certain angle along the axis direction of motor; Rotor core reverses equal angular to embed permanent magnet corresponding to permanent magnet.
The windup-degree α of said permanent magnet is between 1 ° to 30 °; Wherein, α is the maximum angle that the both ends of the surface of permanent magnet are reversed.
Rectangular or the magnetic shoe shape of said permanent magnet.
Said permanent magnet is radial magnetizing or parallel magnetization.
The utility model is through reversing certain angle with permanent magnet along the axis direction of motor; Make the oblique utmost point of permanent magnet; Both obviously improved the voltage waveform of responding in the stator winding; Reduce cogging torque, reduced the torque pulsation and the stray loss of motor, realized the high efficiency of compressibility, low vibration, low noise and even running.
The utlity model has simple and reasonable, flexible operation, cogging torque is little, vibration is low, noise is low, torque pulsation is little, stray loss is little, the characteristics of operation high efficiency smooth.
