The present invention relates to a stackable lamination for rotors of electric motors having inclined or helical slots, and a method for manufacturing the lamination. The lamination comprises at least one boss projecting from a face thereof for coupling with a second lamination in the same pack. The two coupled laminations are rotated according to an offset angle. Advantageously, a boss portion has a lower thickness than the remaining portions to allow the same boss to be coupled with a matching boss of the second lamination, the two coupled bosses being angularly offset according to a preset angle. The reduction in the boss thickness is carried out during the manufacturing step of the lamination.
