Electrical overhead conveyor has contactless energy transfer, return line formed by running rail, pick-up with two separate windings for different supply voltages

摘要

The conveyor has contactless energy transfer from a supply line along a running rail (1), connected to a high frequency AC source and with a return line (7) via a U-shaped ferrite core current pick-up to a control and power stage on a transport unit on the rail. The return line is formed directly by the running rail and the pick-up has two separate, different windings for providing different supply voltages for the power or control stages.
