  • Toroidal electrical transformer and method of producing same
    Patent number: 4779812
    Abstract: A toroidal electrical transformer having a low voltage coil, a high voltage coil and an annular magnetic core is disclosed. The preferred low voltage and high voltage coils are each continuous in substantial part over their length and form an arcuate elongated passage therethrough. The preferred annular magnetic core is wound in place in said arcuate elongated passage substantially from a continuous strip of magnetic material. Various components and sub-assemblies are also disclosed along with various apparatus and methods for producing such toroidal electrical transformer, its components and its sub-assemblies.
    Type: Grant
    Filed: January 15, 1987
    Date of Patent: October 25, 1988
    Assignee: Kuhlman Corporation
    Inventors: John L. Fisher, Herbert J. Macemon, James D. Richerson, Richard W. Wiedo, Joe E. Curtis, Jr., James F. Rafferty, Thomas H. Aishton
  • Apparatus and method for fabricating a low voltage winding for a toroidal transformer
    Patent number: 4665952
