Referring to fig. 11 and 12, a specific calculation method is as follows.
Firstly, an x-axis coordinate system and a y-axis coordinate system are established on the horizontal section of the sheet layer 111, and the center of the iron core circumcircle 21 is taken as the origin of the coordinate system. The width of the oil passage 202 is set to u, the section of the oil passage 202 is provided with a central axis, and the included angle between the central axis and the x axis is 60 degrees. The longer side of each of the sheets 111 is parallel to the x-axis. The radius of the core circumcircle 21 is set as R. A small circle with the radius r is defined on the horizontal section of the frame edge 11, the small circle is tangent to the iron core circumcircle 21, and meanwhile, the small circle is tangent to the side edge of the frame edge 11 facing the window 13. The radius of the chamfer 204 is dr.

(x-xor)2+(y-yor)2＝r2(5)
the coordinate value D (x) of D can be calculated by combining equations (4) and (5)D,yD)。
Since the small circle is tangent to the BC edge at the same time, the coordinate B (x) can be further calculatedB,yB)、 C(xC,yC)、F(xF,yF) And a layer height δ 1 and layer widths B1, B2.
From the value of Bmin in combination with equations (2) and (4), E (x) can be determinedE,yE)、AE(xAE,yAE)。
Since B1+ B2 is B7+ Bn, B7 can be calculated when the A, B, C, F, E, AE coordinates are known, and E1 (x) can be determined by combining equations (2) and (4)E1,yE1)、AE1(xAE1,yAE1)。
When the coordinates of the points are known, δ 1, δ m can be calculated.
Knowing the above data, the middle line length C of the ABCF layer can be calculatedP1Middle line length C of Bmin layerPn。
Further, the total tape length of the ABCF layer can be calculated as follows: l isP1＝1.5×CP1×(δ1/Ph)；
Total length of the band on the Bmin layer: l isPn＝1.5×CP1×(δn/Ph)；
The total length of each layer of material belt is as follows: l isP＝LP1+LPn2; the middle line length of the middle material belt is CIn P(ii) a The total length of the intermediate material belt is LIn P(ii) a The number of the intermediate material belts which can be grouped is as follows: n ═ LIn P/LP(carry rounding).
From the above-described correlation formula and the obtained data, the layer thickness and the layer width of each of the sheet layers 111 and the coordinates of each point can be obtained. From these data, the horizontal cross-sectional area of each sheet 111 and, in turn, the horizontal cross-sectional area of the frame 11 can be determined.
