Description
Technical field
The utility model relates to generator component, especially the stator punching of generator.
Background technology
The single-phase AC synchronous alternator stator piece structure that existing general small-size gasoline engine generator group is used, is to adopt full circle to cut away a part of circular arc, forms the structure of four arcs and four straight flanges.In stator piece inner circle, be covered with teeth groove, magnetic circuit is distributed with irrational place, the close height of local magnetic of straight flange after trimming, and the local magnetic of arc-shaped edges is close low, has not only increased the copper consumption of generator, and has reduced the electromagnetic conversion efficiency of generator.
We know, the stator piece contour structures of single-phase AC synchronous alternator is determining the volume of stator core and the consumption of iron and copper.
The groove distributing in stator piece inner circle is in order to place the enameled wire loop of difference in functionality.And enamelled wire how many with by iron amount, how much be the unity of opposites." facewidth " between groove and groove is magnetic field path, determining the size of power output.How to make copper iron consumption reach the key that the best is motor magnetic Circuit Design.The decisive factor that affects motor quality has: (1) enamelled wire number of turn is how many; (2) magnetic field path: yoke is wide; (3) magnetic field path: the facewidth; (4) magnetic flux size; (5) the how many enamelled wire numbers of turn of diverse location groove embedding; (6) where difference in functionality enamelled wire winding is embedded in; (7) core volume length etc.
Magnetic flux is determined active conductor number, and magnetic field path is determined magnetic field energy loss.Yoke is wide, the facewidth is just definite when design, after mould manufacture completes, just cannot change, and therefore can only adjust: (1) enamelled wire number of turn is how many; (2) the how many enamelled wire numbers of turn of the groove embedding of diverse location; (3) where difference in functionality enamelled wire winding is embedded in; (4) factor such as core volume length.As can be seen here, the importance of wide, the facewidth of yoke.
Utility model content
The purpose of this utility model is to provide a kind ofly to be guaranteed under the prerequisite that rated output power is constant, makes copper consumption and is all reduced by iron amount, and cost obtains the stator punching for general small-size gasoline single phase synchronous generator obviously reducing.
In order to realize above-mentioned technical purpose, stator punching for general small-size gasoline single phase synchronous generator of the present utility model, on cylindrical, there are four straight flanges that form through blank, every two straight flanges are parallel and equal, article two, the straight flange being parallel to each other is vertical and unequal with another two straight flanges that are parallel to each other, in inner circle, there is teeth groove, teeth groove district corresponding to main winding accounts for 2/3rds of whole inner periphery, yoke district accounts for 1/3rd of inner periphery, teeth groove district in inner circle is provided with two sections about center of circle symmetry, slotless in yoke district inner circle, straight flange on yoke district cylindrical lengthens and is extended down to cylindrical corresponding to teeth groove district, the arc length of teeth groove district yoke portion lengthens and is extended down to yoke district.
Stator piece of the present utility model cuts away four not isometric limits on cylindrical.According to single-phase AC synchronous alternator principle, single-phase AC synchronous alternator stator piece is in inner circle in equally distributed teeth groove, main winding accounts for 2/3rds, yoke district accounts for 1/3rd, in yoke district inner circle, do not arrange teeth groove, and its structure is equivalent to cut away one section of arc length on yoke district cylindrical, Er teeth groove district yoke portion increases by one section of arc length.
The utility model is wide and magnetic field path by appropriate design yoke, makes generator unit stator magnetic circuit more reasonable, and the magnetic field energy of consumption is less, and is guaranteeing under rated output power prerequisite the optimum efficiency that obtains copper consumption and all reduce by iron amount.
