SIMOTICS HV Series Metals
SIEMENS | INNOMOTICS SIMOTICS HV Series Metall
High voltage synchronous motors specifically designed for main rolling mill drives set themselves apart as a result of their extremely smooth running properties and dynamic performance. This results in maximum quality of the rolled metal and the highest throughput of the plant.
Your advantages
-
Optimum adaptation to the torque and speed requirements of the rolling process
-
Sufficient power reserves for process tolerances and the ability to add new steel types to the range
-
Short reversing times for a high throughput
-
Power reserves for high throughput. Constant tension over the complete speed range, outstanding control dynamic performance secures consistently high quality of the rolled material
-
Absorbs the axial forces of gearless rolling stands even in fault situations
-
Continuous disturbance-free motor operation for the highest degree of availability of the complete plant
-
Low capital investment, lower lifecycle costs
-
Cost/time saving for retrofits
-
Process know-how secures high-quality, competent service
Features
-
Wide speed control range with constant power rating (field weakening)
-
Overload capability up to 275 % of the rated torque: minimum speed changes – also for maximum load changes (e. g. for the load impact of heavy passes)
-
Low moment of inertia, e. g. for reversing motors
-
Slip-ring excitation
-
Pedestal bearings for high power ratings: can withstand axial surge loads of up to 700 tons
-
Rugged technology with a long service life
-
Compact, material-optimized motor design
-
Adapted to address customer requirements: e. g. existing foundations
-
Large installed base – more than 3300 rolling mill motors worldwide
