As depicted in figs. 1 and 2, the isometric 3-D triangle of Pyatyi, which is remained silent, rolls up iron core, including three identical single frames 9, adjacent
The stem of single frame 9 is mutually combined, colligation together, each single frame 9 is equipped with ground strip.The single frame 9 by Pyatyi material strip successively
Continuous winding forms, and the cross section of single frame 9 is close to semicircle stairstepping.As shown in Figure 4 and Figure 5, the Pyatyi material strip of single frame 9 is wound
Trapezoidal, trapezoidal material strip is carried out cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing processing and obtained using special broken line cutting machine to straight band, straight bandwidth be equal to every grade it is trapezoidal
The original width and finality width sum of band, length is then depending on product number of units.The corner of the single frame is provided with rounded corners 10,
Convenient winding, is easy to solid shape.
The processing of single frame 9 is that strip continuous winding at different levels is fixed into silicon steel on core plate, then with argon arc welding spot-welding equipment
Piece, last material strip are made annealing treatment together with band core plate.The purpose one of annealing is to give volume iron core sizing, second, eliminating
Stress caused by silicon steel sheet among manufacturing process, reduce open circuit loss.After single frame 9 completes annealing, then by three identicals
Single frame 9 carries out assembling on special assembly or fitting table and banding fixed, finally the wound around coil on stem.
As shown in figures 1 and 3, the level angle corresponding to the material strips at different levels of each single frame 9 is respectively α 0, α 1, α 2, α 3, α 4, α
5th, α 6, α 7, α 8 and α 9；Piece a width of b1, b2, b3, b4, b5, b6, b7 and b8 corresponding to material strips at different levels；When the Pyatyi is trapezoidal
9=8 ° of 1=20 ° of 0=10 ° of level angle α, α, the α and 8=18.3737 ° of α of material strip, perseverance have the width of first order material strip 1 to be equal to twice of level V
