Abstract:
A method of manufacturing a core for an electrical machine. The method includes providing a planar sheet of magnetic material and creating first and second generally U-shaped laminations from the planar sheet. The first and second generally U-shaped laminations result from a pattern formed in the planar sheet. The pattern includes the first generally U-shaped lamination having a first leg and a second leg, and the second generally U-shaped lamination rotated one hundred-eighty degrees with respect to the first generally U-shaped lamination. The second generally U-shaped lamination includes a third leg and a fourth leg. The third leg is disposed between the first and second legs. The method further includes creating the core by stacking the first and second generally U-shaped laminations.
