Abstract
Official abstract text for this publication.
Disclosed are methods, apparatuses, and systems with regard to laminations. In an embodiment, an apparatus includes a lamination having a variable thickness and a spacer connected with the lamination at a location, wherein the location of the spacer is based on a determined thickness of the lamination.
First claim
Opening claim text (preview).
What is claimed: 1. An apparatus comprising: a lamination having a variable thickness; and a spacer connected with the lamination at a first location, wherein the location of the spacer is based on a determined inconsistent thickness of the lamination that causes a parallelism error on the lamination. 2. The apparatus of claim 1 , wherein the spacer comprises a polymer. 3. The apparatus of claim 2 , wherein the polymer comprises at least one of polyurethane, polyester, phenolics, polyimide, or enamel. 4. The apparatus of claim 1 , wherein the spacer comprises at least one of: alumina, zirconia, silicate, or other inorganic filler. 5. The apparatus of claim 1 , wherein the location on the lamination is at least one of: a length-wise top edge or a length-wise bottom edge of the lamination. 6. The apparatus of claim 1 , wherein the location on a lamination coincides with at least one of a dovetail area of the lamination or a tooth area of the lamination. 7. The apparatus of claim 1 , wherein the spacer has a variable thickness. 8. The apparatus of claim 1 , further comprising: a second side spacer connected with the lamination at a second location on a second side that is opposite the first location of the spacer, wherein the second location of the second side spacer is based on a thickness of the lamination. 9. The apparatus of claim 1 , wherein the spacer has a thickness based on the determined inconsistent thickness of the lamination to correct the parallelism error on the lamination. 10. The apparatus of claim 1 , wherein the spacer is one of a plurality of spacers each connected with a plurality of laminations, the spacer contributing to an approximately level stacking of the plurality of laminations.
