Abstract
Apparatus and method are provided for induction heating of one or more components of a complex-shaped workpiece. The component is positioned within an opening formed by opposing pairs of arcuate coil structures formed in opposing inductor segments. One inductor segment is formed from electrically isolated inner and outer active inductor segments connected to one or more power supplies, while the other inductor segment is formed from electrically isolated inner and outer passive inductor segments that are magnetically coupled with respective inner and outer active inductor segments. Changing the output electrical parameters of the one or more power supplies controls the induction hardening along the transverse width of the workpiece with optional flux concentrators between opposing pairs of arcuate coil structures.
