Beschreibung
Zusammenfassung:	An inductor for stationary induction heating of one or more components of a complex-shaped workpiece comprises a pair of inductor segments. The first inductor segment is connected to a high frequency ac power supply and the second inductor segment is magnetically coupled to the magnetic field created by the flow of ac current in the first inductor segment. Opposing partial openings in the first and second inductor segments form an opening in which the component can be inductively heated. The first and second inductor segments are alternatively configured in a mix of single turn, multiple single turns connected in parallel, or multiple turn coils in combination to reduce non-uniform induced cross sectional currents across the axial length of the component being inductively heat treated.
