Vector control solves problems in paper cup machines

摘要

A drive operating in an open-loop vector control mode has helped to a German machinebuilder to solve issues in machines that produce up to 180 paper cups every minute. The drive has helped to curb voltage spikes, losses and braking resistor temperatures. We don't usually pay much attention to paper cups, but we rely on them to meet high quality standards day after day. They must keep their contents warm without burning our fingers, and must not leak or spill. And billions of them need to be produced in a cost-effective manner. The German machine-builder, Michael Horauf Maschinenfabrik, specialises in equipment for producing disposable cups. As well as making machines for the efficient production of paper cups, it also supplies machines to branded companies which use them to produce laminated paper packaging in-house.
