Abstract
A method including bending an elongate portion of a flat strip of metallic material into a ring about an axis extending parallel to a thickness of the elongate portion of the strip of metallic material. The method includes fixing end portions of the ring together to form a flat ring, the flat ring having opposite flat side surfaces, a radially inner surface, a radially outer surface, a pair of radially inner edges, and a pair of radially outer edges, wherein the pair of radially inner edges connect the radially inner surface and the opposite flat side surfaces and the pair of radially outer edges connect the radially outer surface and the opposite flat side surfaces. The method includes connecting a plurality of curved blades to the flat ring and connecting a hub support to the curved blades at a position spaced from the flat ring along the curved blades.
