three-phase slip-ring motor:
Make: EMZ | Power: 1.200 kW | Voltage: 6.000 V | Frequency: 50Hz | Speed: 742 rpm | Protection class: IP 23 | Cooling type: IC 06
EMZ manufactured an 8-pole high-voltage motor with 1,200 kW for a steel mill in Egypt. The engine replaces an over 40-year-old Marelli drive. A crucial factor in this project was the main mounting dimensions, since the new motor had to precisely fit the old motor’s dimensions. This advantage enabled a quick and cost-effective retrofitting of the installation. Naturally, the technical data also had to be designed specifically for the mill application. In addition to “standard data” such as voltage and power, overload capability (in this case 1.8 times the nominal load) and starting time were important issues. Finally, the engine was successfully commissioned in June 2018 by the EMZ service team.
