Over the next few years engineers at the newly founded SiemensSchuckertwerke SSW headed by Carl Kttgen laid the groundwork for the power needed for rolling mill drives. On the basis of their discoveries in 190607 Kttgen now a deputy member of the SSW Managing Board built the worlds first electric reversible drive for a blooming mill at the Georgsmarienhtte steel mill near
Power rating 2 6000 kW With over 100 years of experience in motor manufacturing Nidec Industrial Solutions is the expert in special application machines. DC machines continue to be used in a variety of markets thanks to their intrinsic value. Based on a modular design our DC machines offer a vast selection of mounting arrangements
The cost and complexity of power and control circuits make them uncompetitive with other types of converter drives for general applications. However they have been used for cement mill and steel mill applications where the mills are directly coupled to the motor which is
Derating motor capacity base on altitude. each motor. A 50 HP motor operated at 6000 feet for example would be derated to 47 HP providing the 40C ambient rating is still required. Altitude Deratring factor kiln head coal mill fans kiln head surplus fans raw mill circulating fans and so on. Two

Ambient temperature and allowable temperature rise are used to determine the rating for a motor. The electric motor industry standard for ambient temperature is 40C. The motor rating is determined by gradually increasing the load of a motor until its steady state temperature rise reaches the allowable temperature rise for the insulation class
Selecting AC Induction Motors for Cement Plant Applications on photo3500 kW ballmill drive for a cement plant in England via Although motors may appear to be the least complicated component in the specification of cement mill equipment The H rating is determined by the power system available at the site. Because the cement
