SIMOTICS HV Series Metals

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
