Description
Technical field
The utility model is related to motor component field, and in particular to a kind of superspeed permanent magnet motor rotor structure.
Background technology
The need for industrialized production, the application of ultrahigh speed magneto is more and more extensive.But it is due to ultrahigh speed permanent magnetism
Motor operationally itself the characteristics of, sectional type permanent magnet surfaces eddy-current loss especially severe, at the same sectional type permanent magnet with
Suffered centrifugal force is also abnormal huge when rotating shaft rotates at a high speed, easily damages, so when being designed to rotor structure, Ying Zhe
The problem of worry these two aspects of resitting an exam.
Either existing ultrahigh speed magneto is that carbon fiber is all bound outside permanent magnet, or it is directly high with one
Strength alloys sheath is substituted, it is difficult to which taking into account both reduces sectional type permanent magnet surfaces eddy-current loss, and it is increased in terms of intensity
This two hang-up of strong protective effect, actual use, which is got up, has various problems.
The content of the invention
In order to overcome the shortcomings of background technology, the utility model provides a kind of superspeed permanent magnet motor rotor structure, energy
Sectional type permanent magnet safely, effectively is protected, rotating shaft surface is thrown away when preventing sectional type permanent magnet from being rotated at a high speed with rotating shaft, is protected
The personal safety of user, prevents from damaging ultrahigh speed magneto.
The technical scheme that the utility model is used is：A kind of superspeed permanent magnet motor rotor structure, including rotating shaft, piecemeal
Formula permanent magnet, nexine carbon fiber, wire of intermediate layer, outer layer carbon fiber；Described sectional type permanent magnet is located at rotating shaft outer surface simultaneously
By nexine carbon fiber colligation in rotating shaft, described wire of intermediate layer colligation is in the surface of nexine carbon fiber, described outer layer carbon
Fiber colligation is in the outer surface of wire of intermediate layer.
As preferred technical scheme, described rotating shaft is 42CrMo materials.
As preferred technical scheme, the described sectional type permanent magnet trade mark is N38EH.
As preferred technical scheme, described sectional type permanent magnet is directly by nexine carbon fiber colligation in rotating shaft.
As preferred technical scheme, described nexine carbon fiber and outer layer carbon fiber is T700-12k carbon fibers.
As preferred technical scheme, described wire of intermediate layer is 430 magnetic conduction wire qualities.
The beneficial effects of the utility model are：The utility model is fine using nexine carbon fiber, wire of intermediate layer and outer layer carbon
Tie up the mode of common colligation sectional type permanent magnet；Nexine carbon fiber main function is that sectional type permanent magnet is applied in terms of intensity
Protection, the effect of wire of intermediate layer is then reduction sectional type permanent magnet surfaces eddy-current loss, and outer layer carbon fiber is in protection sectional type
Helped out in terms of permanent magnet.
The utility model can safely, effectively protect sectional type permanent magnet, prevent sectional type permanent magnet from being revolved at a high speed with rotating shaft
Rotating shaft surface is thrown away when turning, the personal safety of user is protected, prevents from damaging ultrahigh speed magneto.
The utility model embodiment is described further below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the overall structure figure of the utility model embodiment；
The A-A sectional views that Fig. 2 is Fig. 1 in the utility model embodiment.
Embodiment
As Figure 1-Figure 2, the utility model provides the utility model and provides a kind of ultrahigh speed of the utility model offer forever
Rotor structure of magnetic motor, includes rotating shaft 1, sectional type permanent magnet 2, nexine carbon fiber 3, wire of intermediate layer 4 and outer layer carbon fiber 5；
Described sectional type permanent magnet 2 by the direct take-up strap of nexine carbon fiber 3 in rotating shaft 1, take-up strap outside nexine carbon fiber 3
There is wire of intermediate layer 4, the outside of wire of intermediate layer 4 is then wound around colligation outer layer carbon fiber 5.In such scheme, nexine carbon fiber 3
Main function is that sectional type permanent magnet 2 is applied in terms of intensity to protect, and the effect of wire of intermediate layer 4 is then to reduce sectional type forever
The surface eddy of magnet 2 is lost, and outer layer carbon fiber 5 is then to coordinate nexine carbon fiber to play auxiliary at the aspect of protection sectional type permanent magnet 2
Effect.The program, which is implemented, can safely, effectively protect sectional type permanent magnet, prevent sectional type permanent magnet from being revolved at a high speed with rotating shaft
Rotating shaft surface is thrown away when turning, the personal safety of user is protected, prevents from damaging ultrahigh speed magneto.
In the utility model embodiment, described rotating shaft 1 is 42CrMo materials, and in such scheme, 42CrMo has
Intensity height, good toughness, the effect of strong shock resistance.
