Abstract
The utility model relates to a kind of folded riveting iron core, comprise rotor and U-shaped stator core, U-shaped stator core is formed by stacking by multiple U-shaped core stamping, the both sides of the closing end of U-shaped core stamping are provided with first group of riveting point, first group of riveting point comprises two riveting points, and two riveting points are the both sides that herringbone is distributed in closing end.The utility model folds the U-shaped stator core of riveting iron core, the setting before comparing, and magnetic resistance diminishes, magnetic efficiency is high, and solving because U-shaped core stamping variable thickness, the problem that the easy two ends of the U-shaped core stamping that in prior art, riveting point causes in centre tilt, bond strength is higher.
Description
Technical field
The utility model relates to a kind of folded riveting iron core and applies the motor of this folded riveting iron core.
Background technology
Traditional folded riveting iron core, need to rely on power supply change device or other servicing units to start, and this spline structure is neither beneficial to cost control, also can have influence on reducing further of folded riveting core volume, device is too much, and the failure rate of folded riveting iron core also can improve greatly.
As shown in Figure 1, when magnetic circuit is by riveting point 1 on stator core, magnetic resistance is comparatively large, and magnetic efficiency is low for the folded riveting iron core of tradition.
The stator core bond strength be simultaneously formed by stacking by multiple U-shaped core stamping is bad.When production, U-shaped core stamping has the ± error of 0.04, and the variable thickness of each U-shaped core stamping, the riveting point 1 of traditional stator iron core is arranged on centre, easily causes two ends to upwarp, cause bond strength bad after riveted joint.
Utility model content
The technical problems to be solved in the utility model is: in order to solve, the folded riveting iron core magnetic resistance of tradition is comparatively large, magnetic efficiency is low, the bad problem of bond strength, and the motor that the utility model provides a kind of folded riveting iron core and applies this folded riveting iron core solves the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of folded riveting iron core, comprise rotor and U-shaped stator core, described U-shaped stator core is formed by stacking by multiple U-shaped core stamping, the both sides of the closing end of described U-shaped core stamping are provided with first group of riveting point, first group of described riveting point comprises two riveting points, and two riveting points are the both sides that herringbone is distributed in closing end.Make the two ends of the U-shaped core stamping after riveting smooth, bond strength is better.
In order to the combination better of multiple U-shaped core stamping, the both sides of the openend of described U-shaped core stamping are provided with second group of riveting point, are provided with the 3rd group of riveting point between first group of described riveting point and second group of riveting point.
Specifically, second group of described riveting point comprises two riveting points, is distributed in the both sides of openend in positive splayed; The 3rd group of described riveting point comprises two riveting points, be arranged in parallel and consistent to the direction of openend with closing end.
The both sides of the openend of described U-shaped stator core are provided with the first polar arc and the second polar arc, the shape of two polar arcs forms the cylindrical radial concave surface with rotor coaxial, each polar arc is that the different two sections of concentric circle arc plane of radius are connected and form, and the first polar arc and the second polar arc form a closed magnetic circuit by air gap and rotor.Each polar arc is that the different two sections of concentric circle arc plane of radius are connected and form, this structure makes two polar arcs form uneven stepped air gap, folded riveting iron core is under this asymmetrical airgaps form, do not need power supply change device or other servicing unit, directly can start after switching on power, thus achieve the self-starting of folded riveting iron core.
Specifically, described U-shaped core stamping is silicon steel sheet.
A kind of motor, comprises folded riveting iron core.
The beneficial effects of the utility model are, the utility model is folded riveting iron core and is applied the motor of this folded riveting iron core, (1) first group of riveting point is arranged on both sides and tilts, compared with the riveting point one being arranged on closing end centre folding riveting iron core with tradition, effectively reduce magnetic resistance, improve magnetic efficiency more than 10%, (2) improve the bond strength of multiple U-shaped core stamping simultaneously; (3) each polar arc is that the different two sections of concentric circle arc plane of radius are connected and form, this structure makes two polar arcs form uneven stepped air gap, folded riveting iron core is under this asymmetrical airgaps form, do not need power supply change device or other servicing unit, directly can start after switching on power, thus achieve the self-starting of folded riveting iron core.
