Packaging manufacturer, USA
EMZ manufactured a special converter set with a power of 67 kVA for an internationally leading manufacturer of packaging machines for testing with US mains voltage and frequency.
The manufacturer's machines are also supplied to the USA. Since different voltage and frequency ranges apply in North America, a special converter set had to be built that can simulate the US power supply system. With this converter set, it is possible to test the systems here in Germany with the American voltage and frequency. The EMZ converter set has an output of 67 kVA, a frequency of 60 Hz and an adjustable voltage of 380 – 480 V. Our EMZ team carried out the installation and commissioning of the converter set on schedule and ready for use.
Kitchen machine manufacturer
EMZ supplies 600 EMK gear motors to a manufacturer of kitchen kneading machines for the catering industry.
Thanks to various attachments, this kitchen machine can be used to whip cream, knead dough and "grind" meat, among other things. The geared motor is operated by a frequency converter, which allows infinitely variable speed control.
Metallurgical plant, Germany
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.
Coal power station, Germany
EMZ supplies two squirrel‐cage motors as a district heating pump drive for a German coal power station.
The motors with a capacity of 1,300 kW each are designed for frequency‐converter operations.
Metal industries, China
EMZ supplied a 315 kW motor for the induced draft fan of a metal industry plant to a German fan manufacturer in China.
The speed of the 315 kW motor is controlled by frequency converters to regulate the volume flow of the induced draft fan.
Fan manufacturers, France
The asynchronous squirrel-cage motor was fitted with a electrically-insulated bearing in the EMZ specialist workshop to ensure faultless operation for the customer. The motor is operated on a frequency converter to allow control of the air flow. The 90 kW motor was delivered to a renowned manufacturer of fans in France.
Gravel extraction, Germany
As the main drive for the suction pump, EMZ supplied three-phase asynchronous motors in a power range between 250 and 400 kW to a German manufacturer of suction dredgers. Due to their use in open-air gravel extraction on floating pontoons, the motors are permanently exposed to all weather conditions. This is a particular challenge, especially in winter with ice, snow and rain. The robust EMK cast iron motors meet all requirements for this application.
Pump manufacturer, Germany
EMZ delivered motors for a pump-test bench to a German pump manufacturer.
The two three-phase motors, which have differences in power, speed and weight, were set up on site.
Crushing plant manufacturer, Germany
EMZ supplied a three-phase squirrel-cage motor with an output of 200 kW as the main drive for an impact crusher to a German crushing plant manufacturer. The machine plant was later used in a quarry in southern Germany.
EMZ supplied various EMK motors as drives for high-pressure pumps to an internationally active pump manufacturer, in particular a 160 kW low-voltage motor.
Machine and plant engineering, Germany
EMZ delivered an 315 kW low-voltage EMK motor to a German machine and plant engineering for the German construction materials industry.
The engine was mounted as the main drive on a rotary crusher and successfully put into operation in a quarry.
