Abstract
The utility model relates to a novel magnet steel fixed structure with motor, it include pivot (1), rotor punching (2), non - with core type magnet steel (3), steel bushing (4) and epoxy sealing layer (5), fold to press in pivot (1) rotor punching (2), a plurality of non -s with the even interval arrangement of core type magnet steel (3) on rotor punching (2) excircle, the non - is closely laminated with rotor punching (2) excircle with the interior circle of core type magnet steel (3), steel bushing (4) cooperation install a plurality of non -s with core type magnet steel (3) the outside, the non - is with setting up epoxy sealing layer (5) between core type magnet steel (3) and steel bushing (4). The utility model discloses simple structure, convenient to use has solved the fixed problem of non - with core type table formula magnet steel, has improved the reliability of motor, because the epoxy sealing layer has sealed the magnet steel, the non -corrosibility of magnet steel has been improved simultaneously, the thickness of steel bushing is the attenuate by a wide margin, has reduced the quality of motor, practices thrift manufacturing cost.
Description
Technical field
The utility model relates to machine field, particularly a kind of magnetic steel fixed structure of Novel electric machine.
Background technology
Permanent-magnet drive system, because of the feature that its efficiency is high, energy density is large, progressively instead of AC Driving System in electric automobiles, and broader applications are in electric automobile.Tradition surface-mounted permanent magnet machine is design braking step on the excircle of rotor punching usually, and magnet steel is arranged between two braking steps, and braking step plays the effect of separation and fixing magnet steel.Its advantage manufactures simply, easy for installation; Weak point is that this kind of structure is only applicable to concentric type Surface Mount structure, cannot be applied to non-concentric formula Surface Mount structure.Inside and outside non-concentric formula magnet steel and magnet steel, the center of circle of circular arc is not in same point, causes the contact of external arc and steel bushing for linear contact lay and non-face contact, adds the danger that rotor flies to escape at high speed.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, the magnetic steel fixed structure of the Novel electric machine providing a kind of structure simple, fixed, and this fixed structure can improve magnet steel anti-corrosive properties, reduces motor weight, save motor production cost simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of magnetic steel fixed structure of Novel electric machine, it comprises rotating shaft, rotor punching, magnet steel, steel bushing and epoxy sealing layer, described magnet steel is non-concentric formula magnet steel, described rotor punching is laminated in rotating shaft, multiple non-concentric formula magnet steel uniform intervals is arranged on rotor punching cylindrical, inner circle and the rotor punching cylindrical of non-concentric formula magnet steel fit tightly, steel bushing cooperation is arranged on outside multiple non-concentric formula magnet steel, arranges epoxy sealing layer between described non-concentric formula magnet steel and steel bushing.Epoxy sealing layer guarantees the close contact of non-concentric formula magnet steel and steel bushing, ensures that non-concentric formula magnet steel fits tightly on rotor punching.
Described cylinder sleeve is the circular steel bushing of thin-walled.The thickness of cylinder sleeve is significantly thinning, can reduce the weight of motor.
Described cylinder sleeve is non magnetic cylinder sleeve.
The utility model has the following advantages: non-concentric formula surface-mount type magnet steel can be securely fixed in the surface of rotor punching by motor magnetic steel fixing structure of the present utility model, what reduce rotor high-speed rotation flies risk of escaping, and improve the reliability of motor, and structure is simple, easy to use, cost is low; Simultaneously because epoxy sealing layer seals magnet steel, make magnet steel and air exclusion, improve the anti-corrosive properties of magnet steel; In addition, the thickness of steel bushing is significantly thinning, reduces the quality of motor, has stronger cost advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-rotating shaft, 2-rotor punching, 3-magnet steel, 4-steel bushing, 5-epoxy sealing layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of magnetic steel fixed structure of Novel electric machine, it comprises rotating shaft 1, rotor punching 2, magnet steel 3, steel bushing 4 and epoxy sealing layer 5, described magnet steel 3 is non-concentric formula magnet steel, described rotor punching 2 is laminated in rotating shaft 1, and multiple non-concentric formula magnet steel 3 uniform intervals is arranged on rotor punching 2 cylindrical, and inner circle and rotor punching 2 cylindrical of non-concentric formula magnet steel 3 fit tightly, steel bushing 4 cooperation is arranged on outside multiple non-concentric formula magnet steel 3, and described cylinder sleeve 4 is the circular steel bushing of non magnetic thin-walled.Steel bushing significantly thickness reduces, and can alleviate motor weight, strengthens motor serviceability, saves production cost.Between described non-concentric formula magnet steel 3 and steel bushing 4, epoxy sealing layer 5 is set.
During concrete this structure of use, frock clamp is utilized steel bushing 4 to be installed to the outer rear flank of non-concentric formula magnet steel, closely epoxy sealant 5 is filled between non-concentric formula magnet steel 3 and steel bushing 4, guarantee that non-concentric formula magnet steel 3 fits tightly on rotor punching 2, ensure that non-concentric formula magnet steel 3 is fixed, reduce rotor high-speed and rotate the danger flying to escape, simultaneously because epoxy sealing non-concentric formula magnet steel 3, make non-concentric formula magnet steel 3 and air exclusion, improve the anti-corrosive properties of non-concentric formula magnet steel 3.
Claims (3)
1. the magnetic steel fixed structure of a Novel electric machine, it is characterized in that: it comprises rotating shaft (1), rotor punching (2), magnet steel (3), steel bushing (4) and epoxy sealing layer (5), described magnet steel (3) is non-concentric formula magnet steel, described rotor punching (2) is laminated in rotating shaft (1), multiple non-concentric formula magnet steel (3) uniform intervals is arranged on rotor punching (2) cylindrical, inner circle and rotor punching (2) cylindrical of non-concentric formula magnet steel (3) fit tightly, steel bushing (4) cooperation is arranged on multiple non-concentric formula magnet steel (3) outside, between described non-concentric formula magnet steel (3) and steel bushing (4), epoxy sealing layer (5) is set.
