Abstract (en)

[origin: US4453150A] This induction winding includes a magnetic core formed by a vertical stack of iron disks separated by air gaps. The disks (8) include a plurality of sector-shaped portions (1) each of which is constituted by a succession of magnetic laminations (6), a first part (12,13) of these laminations are all of identical length and a second part (14) are of regularly decreasing length from one lamination to the next. The direction (F1) in which the laminations are rolled in the mill is perpendicular to the axis (7) of the winding. The increased magnetic loss that this causes is compensated by the improved filling coefficient that can then be readily obtained.
