Electric conveyor belt drive system for a light movable conveyor belt uses three-phase alternating current motors as drives fed from 230 volt mains via a common single-phase frequency converter

摘要

A conveyor belt's speed can be altered continuously through externally operated control elements by means of a single-phase frequency converter (FU) in a central control unit (CCU). A complete belt chain can be reversed and operated with no shaking by means of the FU in the CCU.
