Siemens is introducing a brand new range of industry-specific motors for steel plants based on the Simotics 1LE1 motor platform. The ventilated Simotics DP Steel Plant Motors are specially designed for applications in the steel industry where, claims Siemens, they meet the high demands in terms of vibrations and shocks according to Class 3M4.
Versions of the new motors are optimized for use with converters of the Sinamics S120 series and, as integrated drive systems, contribute to reliable and efficient operation, claims the company, adding that, In network operation, the IE3 efficiency class ensures particularly high energy savings.
The Simotics DP Steel Plant Motors offer optimised solutions for steel production processes including the transport processes – for example, transport to the reheating furnace and cooling bed or on beam rolling mills or run-out tables. The motors feature a mechanical design that has been continuously tested in accordance with to DIN EN60721-3-3 and are claimed to exhibit ‘a correspondingly high resistance to vibration and shocks, compliant with Class 3M4’.
The motors are available in 4- and 6-pole designs with shaft heights from 112mm to 280 mm and in the torque range from 20 Nm to 578 Nm. The Steel Plant range comprises not only mains-powered motors, but also versions optimised for converter operation with special insulation systems. When used together with the Sinamics S120 drive system, these motors form an integrated drive system that contributes to particularly dynamic and reliable production processes, claims Siemens.
According to Siemens, operation with the Sinamics S120 converter enables group drives to be implemented with a high level of synchronisation.
