Apparatus and method for constructing three-dimensional laminated shapes for field pole structures
View Patent ↗A method for constructing a three-dimensional laminated shape includes selecting a first lamination strip from a plurality of lamination strips with different widths assembled on a spool. The first lamination strip is stacked on a stacking device and is cut at a first lamination length. A second lamination strip is selected from the spool. The second lamination strip is stacked and cut at a second lamination length different than the first lamination length. The process is repeated to construct a three-dimensional laminated shape of an electrodynamic device. In another embodiment, a computer readable storage medium includes executable instructions to collect design information characterizing a three-dimensional laminated shape and compute lamination parameters based on the design information. The computer readable storage medium further includes executable instructions to direct a plurality of components to construct a three-dimensional laminated shape of an electrodynamic device based on the lamination parameters. The three-dimensional laminated shape comprises a plurality of lamination strips of different lamination widths and different lamination lengths.
