Abstract

An oscillating conveyor comprising an oscillating rail, at least one electromagnet with a coil, and an armature connected to the oscillating rail, which armature can be moved by activation of the coil to generate an oscillation of the oscillating rail, wherein the coil is part of an oscillator circuit, wherein the oscillator frequency of the oscillator signal of the oscillator circuit depends on the inductance of the coil, which is influenced by the position of the armature relative to the coil, wherein the oscillating conveyor comprises a feedback circuit, which drives the coil by means of a control signal which maps the change over time in the frequency of the oscillator.
