MANUFACTURING DEVICE AND METHOD FOR PRODUCING AN ELECTROMAGNETIC ELEMENT FOR AN ELECTRICAL MACHINE

摘要

The manufacturing device for bending an electromagnetic element of an electrical machine, which includes a stator lamination (5), has a first device (10) for bending the stator lamination (5) to form a pre-curved stator lamination and a second device (25) for final forming of the pre-curved stator lamination. The second device (25) includes a first assembly (29) 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 (10) includes a bending mandrel (11) around which the stator lamination (5) bendable, which has an outer diameter that is larger than an inner diameter of the fully bent electromagnetic element.
