<p>In accordance with the teachings of the present invention, flow-through rotor apparatus and methods for making the same from magnetic material in strip form are provided. According to a preferred embodiment of the present invention a strip of magnetic material is wound upon a hub to form a cylindrical structure having first and second circular faces having a desired diameter and width between faces corresponding to the width of the magnetic material in strip form. A plurality of equally spaced radial slots are cut into one of the circular faces to a selected depth corresponding to a portion of the width between faces. A spider formed of conductive material and having one spoke for each slot cut is then placed into the circular face having a plurality of equally spaced radial slots cut therein. The cylindrical structure is then reversed and a plurality of equally spaced radial slots are cut into the remaining one of the circular faces at locations corresponding to the locations at which slots were cut into said one of said circular faces to a depth corresponding to the remaining uncut width between faces. Thereafter a spider formed of a conductive material and having one spoke for each slot cut is placed into said remaining circular face to complete the formation of a flow-through rotor formed of magnetic material in strip form.</p> |
