Two of the technical scheme of realization above-mentioned purpose is: a kind of large and middle size motor manufacture method of link fanning strip may further comprise the steps:
Calculate each fan-shaped film trap and count step, according to the different groove number of different size motor and the quantity of required fanning strip, the groove number that calculates each fanning strip with the position of guaranteeing seam all in the center of groove;
The blanking step, the punching out seam is the fanning strip of dove tail shape on a plate, counts the groove number that calculates in the step according to each fan-shaped film trap of calculating and carries out blanking;
The splicing step, the fanning strip that punching out in the blanking step is gone out splices to form a full circle shape punching;
The punching out step with a full circle shape punching that is spliced into, and is carried out the flute profile punching out thereon.
Above-mentioned a kind of large and middle size motor manufacture method of link fanning strip, wherein, in the described punching out step, the single impression die punching out is adopted in the flute profile punching out.
Above-mentioned a kind of large and middle size motor manufacture method of link fanning strip, wherein, described fanning strip is made up of four first fanning strips and two second fanning strips, and this first fanning strip is 29 grooves, second fanning strip is 28 grooves, wherein between two second fanning strips two first fanning strips is set at interval.
The invention has the beneficial effects as follows: a kind of large and middle size motor of the present invention is with linking fanning strip and manufacture method thereof, connecing between the two adjacent fanning strips met and adopted dove tail shape, this structure can make radially being effectively controlled with tangential displacement between fanning strip, reduced the positioning requirements of stretching screw hole and keyway, and after fanning strip is spliced into a circle, available single impression die punching out, its flute profile is unfettered, under the variable situation of flute profile, the punch die cost reduces greatly.The manufacture method of this large and middle size motor link fanning strip of the present invention because the displacement between the fanning strip can better controlled be lived, no longer needs to use stretching screw fastening, and the fixed form of lamination can be with the punching of diameter below 1000mm, and is simple to operate.
