Wanderfeldinduktor

The invention proposes a travelling wave inductor, in particular for use in devices for the separation and destacking of metal sheets which are placed in a fixed arrangement in relation to the travelling field inductor, whereby the travelling field inductor is connected to a multiphase supply network via a frequency converter. Capacitors are allocated to the inductor windings in such a way that the windings form the inductance and the capacitors form the capacitance of a parallel resonance circuit. A further inductance is switched in series to the parallel resonance circuit, said inductance forming a series resonance circuit with the capacitance of the parallel resonance circuit.
