6-MW high-voltage extruder motor speedily adapted
A petrochemical plant operator urgently needed to replace a failed extruder motor featuring 6 MW rated power, 10 kV nominal voltage, requiring >57 kNm nominal torque. Originally, the extruder was driven by a squirrel-cage motor. However, a motor with similar design parameters was not readily available on the market.
Fortunately, Menzel Elektromotoren based in Berlin, Germany, was able to offer a suitable three-phase slip ring motor. A slip ring motor design also offered significant advantages for the target application, driving an extruder, as it provides the required full torque from standstill.
Flexible configurated extruder motor delivered within two weeks
MENZEL could quickly procure a starter for the slip ring motor as well as implement all necessary modifications in-house. Thanks to a delivery time of only two weeks, the customer restarted the extruder system at the earliest possible moment.
Our modular MEBSSL motor series is explicitly designed to enable flexible configuration for various applications and conditions. One of the most time-consuming jobs in the case of this extruder application was fitting a bushing in the customer’s coupling hub, machining it from a diameter of 280 mm to 240 mm. In addition, MENZEL manufactured adapter plates for the motor to adjust the shaft height from 800 mm to the failed motor center height of 900 mm. The replacement motor is designed with protection class IP55 and cooling type IC 611 with an air-to-air heat exchanger.

Commissioning by MENZEL electric motor experts
After the electric motor had undergone its final tests in our Berlin test facility, our MENZEL motor experts also accompanied the commissioning of the extruder drive. In this case the journey to the final installation site was less far and led the colleagues to the west of our country. The motor was aligned, wired and successfully commissioned on site.
Our motto is “Passion for electric motors”. We see ourselves as a service provider who can create tailored drive solutions for you really quickly. At the same time we offer competent services and consulting from your very first inquiry up to the commissioning of your MENZEL motor and far beyond.
In the event of motor failure, a replacement manufactured from scratch is hardly an option
When large motors operating at high output fail, a replacement manufactured from scratch can hardly be the solution because of the long lead times and the resultant loss of production. Instead, customized configuration of a suitable standard motor is an economical alternative. MENZEL maintains one of the most extensive stocks of large industrial motors in Europe.
We always keep three-phase asynchronous squirrel cage motors and slip ring motors as well as direct current motors in different sizes in stock so that we can supply the motor you need really quickly if necessary.
