Abstract
The manufacturing device for bending an electromagnetic element of an electrical machine, which includes a stator lamination (), has a first device () for bending the stator lamination () to form a pre-curved stator lamination and a second device () for final forming of the pre-curved stator lamination. The second device () includes a first assembly () for axially fixing and pressing the pre-curved stator lamination and a second assembly for radially centering and pressing the pre-curved stator lamination. The first device () includes a bending mandrel () around which the stator lamination () bendable, which has an outer diameter that is larger than an inner diameter of the fully bent electromagnetic element.
