Abstract

The laminar packet, for a machine's armature, is manufactured by punching holes from a number of discs which are then combined to form the packet. The centre of each disc is punched out to give a circular hole and elongated radial holes are punched in the disc near the periphery to form the winding slots. Each disc has a depression (6) pressed into it by deep drawing. The projecting part of this depression locates in the hollow part of the depression in the disc below such that all the discs engage one another to form a stable stack.
