Custom-made replacement motor for two extruders

The DC motor supplied by Menzel features a performance of 472kW and nominal speeds of 1400 or 1710 min-1 respectively, to replace each of the two extruders if necessary.

René Gaebel, head of DC & Special Drives for Menzel, explains: "The customer was able to avoid the costly implementation of a second spare motor, because this two-in-one replacement motor has been adapted to the on-site limitations and two different installation conditions by us." His team constructed the motor with an active terminal box on both sides and installed a custom shaft for an adjustable connection to either extruder. To accommodate the different lengths of the two motors, a flexible foot mounting with long slots at the front and back was installed.
