1. A single-shot inductor for an induction heat treatment of a complex workpiece comprising an at least partially cylindrical component with its central axis coincident with the central axis of a circular component, the at least partially cylindrical component connected at one end to the circular component and the circular component having a circular component diameter larger than a cylindrical component diameter of the at least partially cylindrical component, the single-shot inductor comprising:
a crossover inductor section, the crossover inductor section comprising a supply crossover section and a return crossover section, the supply crossover section having a power source supply end and a supply leg crossover section end, the supply leg crossover section end opposing the power source supply end, the return crossover section having a power source return end and a return leg crossover section end, the return leg crossover section end opposing the power source return end, the supply crossover section and the return crossover section electrically isolated from each other between the power source supply end and the power source return end, the power source supply end and the power source return end located adjacent to each other and separated by a dielectric; a collar inductor section, the collar inductor section comprising a first collar section and a second collar section, the first collar section having a first collar section supply leg end and a first collar section return leg end, the first collar section return leg end opposing the first collar section supply leg end, the second collar section having a second collar section supply leg end and a second collar section return leg end, the second collar section return leg end opposing the second collar section supply leg end; a supply longitudinal leg inductor section having a supply leg crossover end and a supply leg collar end, the supply leg collar end opposing the supply leg crossover end, the supply leg crossover end connected to the supply leg crossover section end, and the supply leg collar end connected between the first collar section supply leg end and the second collar section supply leg end; and a return longitudinal leg inductor section having a return leg crossover end and a return leg collar end, the return leg collar end opposing the return leg crossover end, the return leg crossover end connected to the return leg crossover section end, and the return leg collar end connected between the first collar section return leg end and the second collar section return leg end to form a continuous electrical conductor from the first collar section and the second collar section around the supply leg collar end of the supply longitudinal leg inductor section and the return leg collar end of the return longitudinal leg inductor section whereby when the at least partially cylindrical component of the complex workpiece is situated between the supply longitudinal leg inductor section and the return longitudinal leg inductor section and the circular component is situated adjacent to the exterior face of the collar inductor section, and an alternating current power source is connected between the power source supply end of the supply crossover section and the power source return end of the return crossover section, the complex workpiece is inductively heat treated. |
