Synchronuous motors <strong>for</strong> maximum mill utilization<br />
Medium voltage source converter<br />
Robust long-lasting motors<br />
At <strong>Siemens</strong>, a wide range of motors<br />
especially suitable <strong>for</strong> the harsh <strong>rolling</strong><br />
mill environment are available. Based on<br />
decades of experience, the design of<br />
<strong>Siemens</strong> motors has been continually<br />
improved in order to withstand the rigid<br />
<strong>for</strong>ces in a <strong>rolling</strong> mill application.<br />
Based on our low-maintenance and<br />
reliable non-salient rotors we are able to<br />
offer the most attractive synchronous<br />
motors <strong>for</strong> main drive systems.<br />
High availability and low maintenance<br />
Compact design without fixing<br />
elements and screw connections<br />
Fewer electrical connections<br />
Vacuum impregnation of whole rotor<br />
Extremely rigid and robust design<br />
Optimal to withstand extreme <strong>for</strong>ces<br />
SINAMICS – Our latest converter<br />
technology<br />
With the introduction of the new<br />
SINAMICS drive technology into the<br />
<strong>rolling</strong> mill sector, <strong>Siemens</strong> offers<br />
solutions <strong>for</strong> nearly all market<br />
requirements, including special design<br />
and layout <strong>for</strong> motor revamps, all<br />
compliant with the above requirements.<br />
SINAMICS is orchestrating a unique<br />
change in drive technology. Based on a<br />
single plat<strong>for</strong>m, SINAMICS drives combine<br />
to <strong>for</strong>m a complete and consistent drive<br />
family that spans the entire per<strong>for</strong>mance<br />
range with regard to flexibility,<br />
functionality and engineering design.<br />
For the <strong>rolling</strong> mill main drive, the<br />
medium voltage source converter<br />
SINAMICS SM150 is already operational<br />
in several mill applications. The SINAMICS<br />
SM150 uses low to high-speed<br />
applications with regenerative supply.<br />
This requires high output power, torque<br />
and dynamic response.<br />
Thanks to its modular design and<br />
superior per<strong>for</strong>mance, the SINAMICS<br />
S120 low-voltage converter meets drive<br />
challenges in a very wide range of <strong>rolling</strong><br />
mil applications, including drives <strong>for</strong><br />
hydraulics, bridles, loopers and tension<br />
reels. Whether synchronous or<br />
asynchronous, all motors and<br />
applications receive optimal support from<br />
SINAMICS S120.<br />
Trans<strong>for</strong>mers – Key equipment <strong>for</strong><br />
reliability and energy consumption<br />
Our holistic approach <strong>for</strong> the design and<br />
layout of competitive <strong>mills</strong> considers<br />
more than the process equipment alone.<br />
The dimensioning of trans<strong>for</strong>mers is<br />
calculated based on the installed motor<br />
power and environmental conditions. The<br />
overload requirements defined by the<br />
operational process and production are<br />
also considered, as is the impact of<br />
energy conversion losses over the years.<br />
