  • High voltage coil winding machine
    Patent number: 4901773
    Abstract: The coil winding machine (10) winds a series of interconnected coil bundles within winding forms (28). The winding forms are transferred from a coil winding station (29), at which the coil is wound in the pie-shaped cavity of the winding form, to a coil removal station (237,293,61), at which the winding form is separated and the coil is removed and placed on a storage arbor (54) in the proper order for later assembly in a transformer, and finally, after reassembly of the winding form, back to the winding station.

  • Apparatus and method for winding a strip of material into an arcuate elongate passage
    Patent number: 4896839
    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 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 resulting in a toroidal transformer with continuous windings and a continuous wound core. Various components and sub-assemblies are also disclosed along with various apparatus and methods for producing such toroidal electrical transformers, its components and its sub-assemblies.

  • Apparatus and method for winding a toroidal magnetic core onto a bobbin for a toroidal transformer
    Patent number: 4765861
    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 fabricated in two semitoroidal sections which together form an arcuate elongated passage therethrough. Two bobbin halves are inserted into the semitoroidal sections of the low and high voltage coils and are joined to form a cylindrical bobbin within the arcuate elongated passage. The preferred annular magnetic core is wound onto the bobbin within the arcuate elongated passage substantially from a continuous strip of magnetic material resulting in a toroidal transformer with continuous windings and a continuous wound core. Various components and sub-assemblies are also disclosed along with various apparatus and methods for producing such toroidal electrical transformers, its components and its sub-assemblies.
