Abstract
The utility model provides a novel rotor sheet of a 168 business machine electric generator. The novel rotor sheet comprises a rotor sheet body, wherein the outer outlines of the two ends of the rotor sheet body are arc. The rotor sheet body is symmetrically provided with a plurality of cable winding grooves; the outer outlines of the two ends of the rotor sheet body are respectively eccentric arcs; and the circle holes of the eccentric arcs are decentred with those in the center of the rotor sheet body. As the arcs of the outer outlines at the two ends of the rotor sheet body are respectively designed to be eccentric arcs, the novel rotor sheet can overcome the phenomenon that the density of the magnetic flow at the closed angle of the rotor sheet is overlarge in the prior art, can avoid the local high temperature since the density of the local magnetic flow is overlarge on the rotor sheet of an engine, reduces the reactive power energy consumption of the electric generator, and improves the output power of the electric generator.
Description
Technical field
The utility model relates to a kind of generator amature punching, is specifically related to a kind of 168 logical machine generator novel rotor punchings.
Background technology
In the prior art, the rotor punching of generator adopts silicon steel sheet to make, the two ends outline of punching body is two concentric circles segmental arcs, the central authorities of punching body have interior circular hole, and two ends outline circular arc of circular hole and punching body is the same center of circle in this, evenly is placed with the line embedding groove that is used to settle motor windings on described rule section, the notch of described line embedding groove is a semi-closed port, around generator main winding and auxiliary winding, the magnetic line of force that winding produces passes through from silicon steel sheet in line embedding groove, forms magnetic loop.And in the punching body: form wedge angle between two ends outline arc section and the line embedding groove, the magnetic flux density of the magnetic flux density that causes formed wedge angle part other parts on the rotor punching, both influenced the power output of motor, influence motor properties again, simultaneously, magnetic flux distribution on the silicon steel sheet is inhomogeneous, and its wedge angle part magnetic flux density causes caloric value bigger more greatly, influences the overall performance of generator.
The major defect of existing generator amature punching is: the two ends outline of punching body is two concentric circles segmental arcs, the central circular hole concentric of these two arc sections and punching body, make between the two ends outline arc section of winding slot cell wall and rotor punching on the punching body and form wedge angle, make this wedge angle magnetic flux density partly much larger than having changeed the magnetic flux density of other parts in the punching, this wedge angle part caloric value is bigger, cause localized hyperthermia, influence the overall performance of generator, increase the idle energy consumption of generator, reduced the delivery efficiency of generator.
The utility model content
Problem at the prior art existence, the purpose of this utility model is to provide a kind of generator amature punching, increased the length of rotor punching pole body, make that the two ends outline of rotor punching body is the arc section of two off-centre, make between the two ends outline arc section of winding slot cell wall and rotor punching on the punching body and form the obtuse angle, when producing same magnetic field on the silicon steel sheet this obtuse angle obviously reduce than the magnetic flux density of wedge angle, avoided the localized hyperthermia in the engine rotor punching, reduce the idle energy consumption of generator, improve the delivery efficiency of generator.
For achieving the above object, the technical solution of the utility model is as follows: a kind of 168 logical machine generator novel rotor punchings, comprise and be provided with the punching body that the two ends outline is a circular arc, symmetry has winding slot on this punching body, the two ends outline circular arc of described punching body is respectively eccentric arc, the not concyclic heart of circular hole in its eccentric arc and the punching body center.
Adopt the technique effect that technique scheme reached to be: the two ends outline circular arc of punching body is respectively the eccentric arc design, can overcome the excessive phenomenon of sharp corner magnetic flux density of prior art rotor punching, can avoid in the engine rotor punching localized hyperthermia that produces because local flux density is excessive, reduce the idle energy consumption of generator, improved the delivery efficiency of generator.
Further, the center of circle of described two eccentric arcs lays respectively at the both sides in the circular hole center of circle in the punching body center.This design can be elongated the length of punching body, further reduces magnetic flux density local in the generator punching.
Further, described eccentric arc and winding slot are in conjunction with forming level and smooth camber line profile.Level and smooth camber line profile avoids forming concentrated magnetic flux density, produces localized hyperthermia, influences the delivery efficiency of generator.
Further, described eccentric arc and winding slot are in conjunction with the structure that forms the obtuse angle.Avoid the joint portion on the generator punching body concentrated magnetic flux density to occur, produce localized hyperthermia, influence the delivery efficiency of generator.
Further, described eccentric arc and winding slot are in conjunction with the fold-type structure that forms the obtuse angle.Further effectively avoid the joint portion on the generator punching body concentrated magnetic flux density to occur, produce localized hyperthermia, influence the delivery efficiency of generator.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further:
Fig. 1 is the structural representation of the utility model a kind of 168 logical machine generator novel rotor punchings.
Among the figure, 1 expression punching body, 2 expression outline eccentric arcs, 3 expression joint portions, circular hole in the 4 expression central authorities, 5 expression winding slots.
Embodiment
As shown in Figure 1, punching body 1 is generally made by silicon steel sheet, and a plurality of punching bodies 1 stack the rotor that forms generator, are symmetrically arranged with winding slot 5 on the punching body 1, are used to twine induction coil.Punching body 1 is strip, its two long end has comprised symmetrical outline eccentric arc 2 respectively, the center of circle of the outline eccentric arc 2 at these two ends is symmetrically distributed in the both sides of the interior circular hole 4 of central authorities of punching body 1, winding slot 5 and outline eccentric arc 2 have a joint portion 3, this joint portion 3 forms level and smooth camber line profile, certainly, this joint portion 3 can be arranged to the folding rule type structure of a non-wedge angle or non-wedge angle for the bigger problem of magnetic flux density that solves better solution joint portion 3, avoid occurring wedge angle or angle.This structure Design can guarantee can not form much larger than the magnetic flux density on the punching body in the magnetic flux density at 3 places, joint portion the localized hyperthermia of joint portion, has guaranteed the delivery efficiency of generator.
Above-described only is preferred implementation of the present utility model; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
