Applicant is carried out to the operation noise for applying the motor of the rotor of the present embodiment with motor of the prior art
Experimental comparison.Experimental result is as shown in fig. 7, it will be seen in fig. 7 that apply the operation noise of the motor of the rotor of the present embodiment
Operation noise of the meditation less than motor of the prior art.
According to said structure, the rotor of the application has the characteristics that：
The application is sealed using plastic packaging or glue or the technology of filling, and magnetite and rotor solidification is integral, makes rotor entirety
Intrinsic frequency quantity reduces, and deflection reduces, and reaches fabulous noise reduction.By test, partial dot can reduce 5-
6dB.Solves the shortcomings that structural strength, magnetic bridge weakness of rotor simultaneously, the effect that magnetite is fixed.Specifically：
1st, permagnetic synchronous motor or direct current brushless permanent magnet synchronous motor, rotor use interpolation magnetite scheme.Use filler
The gap between magnetite, rotor core is filled, it is an entirety that both, which are fastened,；
2nd, when magnetite, rotor by bond or injection, filling technique permeate entirety after, the intrinsic frequency of rotor,
Significant changes will occur for the amplitude of corresponding intrinsic frequency, and frequency can significantly improve, and amplitude significantly reduces, and it is intrinsic also to eliminate part
Frequency.So as to reduce because rotor air-gap field effect under caused by noise, vibration；
3rd, bond, be molded or filling technique is, it is necessary to as far as possible using rigidity is larger, the preferable material of globality after solidification, from
And preferably ensure the globality after filling.Can more effectively be lifted 1-6 orders admittedly frequently value and reduce amplitude, reach to greatest extent
Reduce noise.Filling can use AB glue water, epoxy resin, PBT, PPS etc.；
4th, on rotor structure, injection, the filling hole of enhancing integraty can be increased, such as on the outside of rotor magnetic steel groove, original button
Point position increase hole, after filling, the filler and end loops of remaining magnet steel groove together, make structure more stable.Determine frequency motor
Rotor uses cast aluminum construction, and its globality is fine, and it is closely bound up that this is low with determining frequency motor noise；
5th, before filling, rotor outer circle needs sheath, and rotor shaft hatch will have asessory shaft, after ensureing before filling, rotor
Every size qualified；
When the 6th, using high temperature die casting, injection, magnetizing is carried out after needing this process again.
The rotor of the application has advantages below：
1st, motor, the noise of compressor are effectively reduced, reducing effect reaches 3-6dB.Interpolation type rotor structure be also motor,
Compressor noise contribution a larger aspect, its structural strength is relatively low, in the presence of electromagnetic force, especially contain compared with
More, more multiple harmonic wave air-gap field.Reduce rotor noise noise it is big the problem of, also indirectly reach reduction because rotor is made an uproar
The increase of complete machine noise caused by sound vibration.Using curing technology, by integrations such as magnetite, rotor core, rivets, change and turn
The solid frequency scope of son, reduces solid frequency and corresponds to vibration amplitude, effectively reach the purpose of noise reduction；
2nd, after integrally curing, baffle plate, rivet arrangement are just eliminated, can reach the purpose for reducing cost；
3rd, after integrally curing, the structural strength of rotor magnetic bridge is substantially enhanced, the safety coefficient of rotor greatly promotes.
