Features

Customer benefits

Wide speed control range with constant power rating (field weakening)

Optimum adaptation to the torque and speed requirements of the rolling process

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)

Sufficient power reserves for process tolerances and the ability to add new steel types to the range.

Low moment of inertia, e.g. for reversing motors

Short reversing times for a high throughput, high control quality in the drive train

Slip-ring excitation

Power reserves for high throughput. Constant tension over the complete speed range, outstanding control dynamic performance secures consistently high quality of the rolled material

Pedestal bearings for high power ratings: can withstand axial surge loads of up to 700 tons

Absorbs the axial forces of gearless rolling stands even in fault situations

Rugged technology with a long service life, proven Micalastic insulation system, cylindrical rotor

Continuous disturbance-free motor operation guarantees the highest degree of availability of the complete plant

Compact, material-optimized motor design

Low capital investment, lower lifecycle costs

Adapted to address customer requirements: e.g. existing foundations

Cost/time saving for retrofits ensures a fast payback time of the investment

Drive system and plant solution possible

Everything from a single source from sector experts, no unnecessary interfaces, high reliability through components that are harmonized and coordinated with one another

Large installed base – more than 3300 rolling mill motors worldwide

Process know-how secures high-quality, competent service from Siemens head office or a Siemens partner close to you
