Metallurgical plant, Germany

Three-phase motor:

Make: EMZ | Power: 1,800 kW | Voltage: 690 V | Speed: 494 rpm. | Protection class: IP55 | cooling type: IC 611 | Weight: 14,300 kg

EMZ manufactured a low-voltage motor with 1,800 kW for a sinter dedusting plant of an metallurgical plant in the Ruhr area. Normally, Motors of this power are designed for high voltage – for example 6 kV. However, since 690 V converters are considerably cheaper than 6 kV converters, the motor was designed for 690 V converter operation. The speed of the 1,800 kW motor is controlled by a frequency converter to regulate the volume flow of the induced draft fan.
