Abstract
Rotors usable in energy storage devices and power systems are formed by orienting a thicker region of a first lamination above a thinner region of a second lamination to form a stacked pair. Multiple stacked pairs of laminations can be positioned in vertical alignment and compressively retained. Usable laminations can be removed from a sheet of material having thicker and thinner regions along its width, each lamination including a visible indicator to facilitate visual identification of the thicker and thinner regions of the lamination. Visible indicators can also be used to identify and position the top and bottom faces of the laminations in the same orientation, and to rotationally offset stacked pairs of laminations from one another to account for possible variations along the length of the sheet of material.
