Abstract
The laminations of a stack that form an iron core for a magneto armature are provided with wart-like deformations produced by through-stamping, so that pressing the stack together will provide a press-fit at the locations of the deformations. The core is mounted by screws through mounting holes respectively in the yoke and at the end of one leg of an E-shaped core, while the press-fits produced by superposed deformations hold the rest of the core together against warping and twisting. Protuberances from the annular cup casing, which contains the winding mounted on the middle leg of the core, grasp the lamination stack in a region remote from the mounting holes to prevent the press-fit locking of the laminations from loosening.
