The data provided in clauses 6 and 7 give the main dimensions of: - length, width, height (A, B, Cl; - positioning of mounting holes (D, D2, D3); - fixing hole site (G); - fixing screw size (M); - stack height (SI. Dimensions A, B and C include

30、 an allowance for varnishing. Fixing screws shall be IS0 metric screws having screw threads which are metric coarse and of medium fit in accordance with IS0 965. .

The increment of stack height follows the R 10 series of preferred numbers, as defined in IS0 3, as a multiple of the w

33、idth of the limbs of the lamination. A suffix letter is used to designate the appropriate stack size as shown in table 1.

NOTE - The appropriate tolerance is shown at the head of each column of dimensions in the foilowifig tables. 6 Vertical mounting style The dimensions for the vertical mounting style shall be as given in table 3, corresponding to the cores using

37、square stacks assembled from laminations YU1 2-20d to YU1 2-80d, in accordance with the outline drawing of figure 1. If stack heights other than the preferred square stack are used, these shall follow the R 10 series given in table 1. In this case the appropriate dimensions are obtained by increasin
