Abstract
The utility model relates to a rotor protective cover for surface mounted permanent magnet motors and belongs to the field of motor manufacturing. The rotor protective cover for surface mounted permanent magnet motors is characterized in that the rotor protective cover has a multi-layer structure which is wound on the magnetic steel surface of a motor rotor, and the rotor protective cover is an ultra-thin epoxy resin-impregnated glass fiber tape. The rotor protective cover for surface mounted permanent magnet motors achieves the purpose of protecting the surface of the traditional surface mounted permanent magnet motor and eliminates the centrifugal force and shear force generated by the surface-mounted magnetic steel during rotation of the motor.
Description
Technical field
The utility model relates to a kind of surface-mount type permanent magnet machine rotor protective jacket, belongs to field of motor manufacturing.
Background technology
The rotor protective jacket of existing surface-mount type magneto mainly contains following two kinds of forms: stainless steel thin-wall cover and do not have latitude band protective jacket.The shortcoming of these two kinds of protective jackets is: the installation of stainless steel thin-wall cover needs special equipment, and the rotor of different size needs the mould of corresponding size, and equipment has high input, and versatility is poor.In addition, stainless steel thin-wall is enclosed within the motor operation course can induce electromotive force and electric current, forms eddy current effect, causes the p-m rotor heating, influences the magnet steel magnetic property; No latitude band is because it has only warp and thickness in monolayer big, when holding rotor, take place discrete easily, after holding, overlapping or multilayer can't carry out machining, can cause motor to sweep thorax, in the small air gap magneto even can't effectively hold into protective jacket, processing technology is complicated, and the scope of application is little.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model provides a kind of surface-mount type permanent magnet machine rotor protective jacket, this surface-mount type permanent magnet machine rotor protective jacket has solved the surfacecti proteon problem of existing surface-mount type permanent magnet machine rotor, and has overcome centrifugal force and shearing force that the Surface Mount magnet steel is produced in the motor rotary course.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of surface-mount type permanent magnet machine rotor protective jacket, this rotor protective jacket adopts sandwich construction to be paperwrapped on the magnet steel surface of rotor, and described protective jacket is ultrathin epoxy resin dipping glass fiber band.
Described ultrathin epoxy resin dipping glass fiber band is paperwrapped on the rotor with warp and parallel eclipsed form.
The thickness of described ultrathin epoxy resin dipping glass fiber band is less than 0.1mm.
The beneficial effects of the utility model are: a kind of surface-mount type permanent magnet machine rotor protective jacket, this rotor protective jacket adopt sandwich construction to be paperwrapped on the magnet steel surface of rotor, and described protective jacket is ultrathin epoxy resin dipping glass fiber band.
The utility model is owing to adopt ultrathin epoxy resin dipping glass fiber band that rotor is held, and the thickness of this fabric strip is less than 0.1mm and have warp and parallel simultaneously, can carry out multilayer and hold and process.High-precision requirement for the rotor excircle dimension is very easy to satisfy.The multi-layer fiber band has very strong tension and crushing resistance through forming the bigger platy structure of a kind of density behind the hot setting, centrifugal force and shearing force in the time of can effectively overcoming the rotor rotation.Because it is the glass fiber band, itself has insulation characterisitic, can not produce eddy current effect in electric machine rotary magnetic field, has avoided the rotor heating, improves electric efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of surface-mount type permanent magnet machine rotor protective jacket;
Fig. 2 is a kind of processing structure schematic diagram of surface-mount type permanent magnet machine rotor protective jacket;
Reference numeral is as follows: 1, rotor, 2, magnet steel, 3, ultrathin epoxy resin dipping glass fiber band, 4, the high temperature modification electrical adhesive tape.
Embodiment
Specific embodiment:
Figure 1 shows that a kind of surface-mount type permanent magnet machine rotor protective jacket, this protective jacket is last formation the in magnet steel 2 surfaces that is paperwrapped in rotor 1 by ultrathin epoxy resin dipping glass fiber band 3.
Figure 2 shows that a kind of processing structure schematic diagram of surface-mount type permanent magnet machine rotor protective jacket.At first, magnet steel 2 is bonded at the surface of rotor 1, thickness is paperwrapped on magnet steel 2 surfaces of rotor 1 less than the ultrathin epoxy resin dipping glass fiber band 3 of the 0.1mm overlap mode with warp and parallel.Then, be coated on outermost layer with high temperature modification electrical adhesive tape 4 and tie tight.Rotor integral body is heated to 110～120 ℃ and be incubated 4 hours, pulls down high temperature modification electrical adhesive tape 4, with machining equipment as requested size the protective jacket cylindrical is processed.
Claims (3)
