Abstract:
1. A field pole member formed in accordance with a method for constructing field pole members for electrodynamic machines, said method comprising: positioning a plurality of magnetic flux conductors in proximity to each other to form at least a field pole core for a field pole member; forming a first sculpted pole face at a first end of said field pole member having an elongated shape; forming a second sculpted pole face at a second end of said field pole member having said elongated shape, said first sculpted pole face and said second sculpted pole face being disposed at opposite ends of said field pole member in an axial direction extending lengthwise along said elongated shape; and forming each of said first sculpted pole face and said second sculpted pole face to include at least a surface portion at an angle greater than 0° and less than 90° relative to a line parallel with an axis of rotation, wherein said first sculpted pole face and said second sculpted pole face are coextensive with a first curved surface portion of a first cone and a second curved surface portion of a second cone, said first curved surface portion and said second surface curved portion are positioned radially from said axis of rotation such that a straight line passes through said first curved surface portion and said curved second surface portion, said straight line being parallel to said axis of rotation, wherein each of said first curved surface portion and said second curved surface portion is uniform, wherein the first and the second curved surface portions are configured to establish a first uniform distance between said first curved surface portion and a first rotor surface and a second uniform distance between said second curved surface portion and a second rotor surface.
