Abstract: A thin spindle motor having a stator core with sufficient swaging strength even using thin magnetic steel sheets is provided, whereby the magnetic loss and the power consumption of the spindle motor are reduced. The stator core is formed by laminating plural stator laminations with a thickness of 0.1 to 0.2 mm and joined by a swaging portion. The swaging portion has an approximately rectangular shape having long sides extending along a radial direction when viewed from an axial direction. The swaging portion has a cross section with a middle portion parallel to the radial direction and a slope portion at the both sides when viewed from a circumferential direction, thereby forming a recess. The recess has a depth that is less than the thickness of the stator lamination whereby the swaging portion does not cut the stator lamination.

The punching structures are arranged along the conveyance direction of the workpiece. The selecting mechanisms select one of the punching structures to be put in a pause state, so that one of the punching structures is put in a pause state during a stamping operation of the punching structures.

Abstract: A method for manufacturing a lamination for electro motor rotors that have skew or helical slots by forming at least one boss on a face of the lamination and reducing a thickness of a first portion of the boss. The reduction in thickness may be by carrying out a localized narrowing of the thickness of the first portion and the boss may be manufactured by pressing the lamination. The localized narrowing may be carried out by misalignment of a die relative to a punch within a mould.
