Description
Technical field
The utility model relates to a kind of efficient axial-flow fan iron core, belongs to aerofoil fan and manufactures field.
Background technology
Iron core is one of most important parts in fan, and traditional iron core is laminated by a large amount of silicon steel sheet, and the actual magnetic resistance that uses is higher, and efficiency is not high.
Utility model content
The utility model, for solving prior art problem, provides a kind of aerofoil fan iron core of efficient logical magnetic.
The technical solution of the utility model is: a kind of efficient axial-flow fan iron core, comprise some silicon steel sheets mutually stacked vertically, described silicon steel sheet circle center is the shaft through-hole of a circle, each described silicon steel sheet comprises some circumferentially equally distributed magnetic flux holes, adjacent described silicon steel sheet, at axial deflection certain angle, the angle ranging from acute angle; After all described silicon steel sheets are stacked, the described shaft through-hole of all same positions forms the magnetic channel that a sidewall favouring described silicon steel sheet axis has some steps.
As preferably, each described silicon steel sheet is provided with several Access Division being uniformly distributed in described shaft through-hole outer circumference, and described Access Division comprises the clamping groove that is positioned at described silicon steel sheet front and is positioned at the protruding with the clamping of described clamping fit depressions of the back side.
As preferably, described clamping projection is along the circumferential direction obliquely installed, and the deflection angle between angle of inclination with adjacent described silicon steel sheet is identical.
As preferably, described clamping groove is along the circumferential direction obliquely installed, and incline direction is contrary with the incline direction of described clamping projection and angle is identical.
As preferably, described magnetic flux hole comprises straight sided that described in two edges, silicon steel sheet radial direction is arranged, outside the arc inner edge and the arc relative with described arc inner edge of described shaft through-hole.
As preferably, the angle between two described straight sided is 8 ~ 15 degree.
As preferably, described arc inner edge is the semi arch that a center of circle is positioned at two inner connecting line mid points of described straight sided.
As preferably, be one section of circular arc concentric with described shaft through-hole outside described arc, its two ends terminate in the outer end of two described straight sided.
As preferably, outside described arc, center is provided with the magnetic groove of outwardly convex.
As preferably, the outermost end of described magnetic groove and the edge minimum range of described silicon steel sheet are not more than 1/100 of described silicon steel sheet diameter.
As preferably, described yawing moment is identical with direction of motor rotation.
Compared with stacked with traditional coincidence system, the utility model adopts deflection stacked, the magnetic line of force is made to produce deflection, due in actual motion, in motor winding, electric current can not be parallel to iron mandrel completely and produces deflection to, the magnetic line of force, keeps vertical with electric current, guarantee motor torque is maximum, most effective.
Adjacent silicon steel sheet adopts clamping groove and clamping projection to fix.The Access Division with certain deflection angle makes adjacent silicon steel sheet can keep unified deflection angle at a touch, is convenient to manufacture.
The setting of magnetic groove can guide magnetic line of force trend, reduces magnetic resistance simultaneously, produces magnetic line of force eddy current, promote magnetic field intensity.
In sum, the utility model has the following advantages:
1, magnetic resistance is little, makes motor efficiency high;
2, structure is simple, and improving cost is low.
