Custom-made replacement motor from Menzel
Menzel Elektromotoren have constructed a special motor for a customer from the plastics industry which can be used as a flexible replacement for two differently designed extruders. The operators turned to Menzel, because no “off the rack” motor was suitable for this particular task. With 90 years of tradition and experience in motor construction, the company specializes in the manufacture of customized motor solutions and can implement versatile adaptations and special designs in its workshop in Berlin.
The motor specialist’s service also includes modifications for DC motors as in this case. The DC motor supplied by Menzel features a performance of 472 kW and nominal speeds of 1,400 or 1,710 min-1 respectively, to replace each of the two extruders if necessary. “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,” explains René Gaebel, Head of DC & Special Drives for Menzel. 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 as well.
