1,800kW drive for an induced draft fan

EMZ built a low voltage motor with 1,800kW for a sinter dedusting fan of a steel plant in North Rhine-Westphalia.

Usually motors of this size are designed for high voltage (e.g. 6kV). In order to regulate the volume flow of the induced draft fan, the rotational speed of the 1,800kW motor is controlled by a frequency inverter. Since a 690V frequency inverter is significantly cheaper than 6kV inverter, the motor was specifically designed for the Voltage of 690V.
