Motor replacement for rubber kneading machine

Customer: Continental Tires (Deutschland)

In one of Germany’s largest tire production plants, the rubber kneading machine is driven by two slip ring motors that are running at different speeds on one single shaft. A special challenge here is the state of the slip ring body, since one of the motors always has to run at a tensionless state. Menzel was asked to produce a completely interchangeable replacement to the old motor, which was originally from the 60s. Since then the new drive is performing to full customer’s satisfaction.
