Abstract
Method for forming a toroid coil on a toroidal body. A wire feeder feeds the wire forward in the direction of its length toward the toroidal body. The wire is fed along a path which at the toroidal body is generally tangent to the surface of the toroidal body and nonparallel to the radial plane of the toroidal body. A die having a wire forming path defined therein constrains the wire to bend as it is fed forward into the convolutions of a helix extending through the opening in the toroidal body and advancing circumferentially around the toroidal body to form the toroid coil. An inductor formed by the method of the present invention is also disclosed.
