Specific embodiment
It is of the invention to achieve the above object, present invention employs the following technical solutions:
Rotor punching of the invention, as shown in Figure 1, including the punching ontology 1 in disc-shaped, the center of the punching ontology 1
It is provided with the axis hole 12 with shaft cooperation, which is equipped with the magnetic shoe mounting hole 13 for being coupled magnetic shoe 4, magnetic
The profile of watt mounting hole 13 by outer circle segmental arc 131, inner circle segmental arc 132, for connecting outer circle segmental arc 131 and inner circle segmental arc 132
Two sections of linkage sections 133 are constituted, and outer circle segmental arc 131 is arranged concentrically with inner circle segmental arc 132, and punching is deviateed in the center of circle of inner circle segmental arc 132
The center of ontology 1, the center of the punching ontology 1 is between Inner arc section 132 and the center of circle of the inner circle segmental arc, magnetic shoe mounting hole
13 are arranged in pairs, and each pair of magnetic shoe mounting hole is symmetricly set on the two sides at 1 center of punching ontology.The outer circle segmental arc 131 and magnetic shoe 4
Extrados 41 is corresponding, and inner circle segmental arc 132 is corresponding with the intrados 42 of magnetic shoe 4.
In the present embodiment, two pairs of magnetic shoe mounting holes 13 are equipped with, two pairs of magnetic shoe mounting holes 13 are mutually symmetrical.
In the present embodiment, punching ontology 1 is equipped with the screw via hole 134 for wearing screw 5.Specifically, the screw mistake
Kong Weisi, four screw via holes are using the center of punching ontology 1 as center of circle circumference uniform distribution.
When magnetic shoe 4 is installed, several rotor punchings are first laminated into setting, form iron core；Then magnetic shoe 4 is passed through into every rotor
The magnetic shoe mounting hole 13 of punching, so that magnetic shoe 4 is equipped in the magnetic shoe mounting hole 13；Finally it is respectively set at iron core both ends
Front apron 2 and rear baffle 3 also are provided with the through-hole for wearing screw 5 on the front apron 2 and rear baffle 3, using screw 5 by its
Axial direction on lock.Certainly, in the specific implementation process, other modes also can be used in the axial restraint of magnetic shoe 4.
Rotor punching of the invention installs magnetic shoe using magnetic shoe mounting hole, simplifies the mounting process of permanent magnetic tile；Due to
The inner circle segmental arc and outer circle segmental arc of the magnetic shoe mounting hole are coaxial, so that rotor punching of the invention is suitable for traditional permanent magnetic tile,
The namely coaxial permanent magnetic tile of intrados and extrados, without processing eccentric magnetic shoe, the technique for reducing magnetic shoe processing is difficult
Degree, reduces production cost；In addition, the harmonic wave in operating fields can be reduced since inner circle segmental arc and punching ontology are eccentric.
In the present embodiment, the center of circle of the outer circle segmental arc 131 deviate the center of punching ontology 1 eccentricity be 1.5mm~
2.5mm.Eccentricity within the scope of this not only guarantees the effect for reducing harmonic wave, but also can prevent because air gap is uneven caused by eccentric excessive
The phenomenon that, it ensure that the performance of rotor.
In the present embodiment, the outer diameter of punching ontology 1 is 98mm~99mm.Punching ontology 1 in the external diametrical extent makes function
Rate is that the air gap flux density of 6~15KW permanent magnet generator is most uniform.

Distance is 22.5mm~26.5mm.Screw corresponding to screw via hole in the diameter range and the screw mistake in the distance range
Hole can not only provide magnetic shoe 4 being pressed on pressing force between front apron 2 and rear baffle 3, and advantageously reduce rotor and exist
The amount of unbalance as caused by screw in rotation process, in practical work process, which will receive screw via hole and punching
The influence of piece body central direct range, also will receive the influence of 5 gravity of screw.
As an improvement of the above scheme, there are two the notches for constituting heat dissipation wind channel for the edge setting of punching ontology 1
135, two notches 135 are symmetrical arranged, and it is convex that the edge of punching ontology 1 is divided into two mutually symmetrical circular arcs by two notches 135
Portion 136, magnetic shoe mounting hole 13 are arranged on the circular arc protrusion 136.When rotor punching of the invention laminates setting, these punchings
On notch 135 constitute heat dissipation wind channel, play the effect of two sides heat dissipation, also, the notch 135 reduces rotor punching and laminates into
Weight after iron core.
Specifically, the notch 135 is sector notch, the angle of the sector notch is 35 °~50 °, and two sector notch make
The angle of circular arc protrusion 136 is 130 °~145 °.The angular range increases practical polar arc, and non-uniform air-gap is influenced to drop
It has arrived minimum.
More specifically, the internal diameter of the sector notch 135 is 30mm~32.5mm, at this point, the wind that the sector notch 135 is formed
The windmill loss in road is minimum.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
