Abstract
An arrangement for notching or slotting circular blanks so as to produce stacks of rotor and/or stator laminations for electric machines. At least one slotting machine is provided which in a first direction is adjustable radially with respect to a spatially fixed axis of rotation of a blank support table by way of a separate adjusting drive. The support table for the blanks, constructed as an indexing apparatus, may be driven by a numerically controlled adjusting drive. The at least one slotting machine is movable in a second direction at right angles to the first direction by way of a further adjusting drive. The stacks of lamination produced by the punching arrangement may include spiral slots or notches as well as oblique slots or notches enabling the production of special motors having a cone or tapered armature.
