The German motor manufacturer application-tailored the 1120-kW squirrel cage motor for a leading Italian operator’s flour mill. Menzel used a machine from its extensive stock, upgraded it for converter operation, adapted the dimensions to the existing motor to enable a smooth replacement, and manufactured an oversized terminal box according to customer specifications.
The mill motor with a nominal voltage of 690 V provides a nominal torque of 11575 Nm. It is suitable for operation in both directions of rotation and features protection class IP55 with IC 611 cooling (CACA air-to-air heat exchanger). Through its Italian subsidiary, Menzel has been the mill operator’s trusted motor supplier for many years. Thanks to its large motor warehouse, application-specific configurations and ATEX certification capability, Menzel can meet virtually any demand from a single source.
