摘要

The invention relates to a drive unit for extractors with vibrating floors with the floors running in the same direction or the opposite direction, with an electric linear oscillating motor 1 which is supplied from the mains via a static converter 6. The static converter for the electric linear oscillating motor is connected, via a frequency input Fd, to the frequency output on a regulating arrangement 5. A measuring member 4 is connected via its input to the armature of the electric linear oscillating motor 1 and via its output to the input of the regulating arrangement 5. The motor 1 is fastened to a system of floors 38 in the extractor 3 via a mechanical connecting link 2. The drive unit according to the invention can advantageously by used for all types of vibrating extractors and in particular for extractors with automatic operation regulation, for installations regulated manually via actuating units, or for apparatus which is connected to a process computer.
