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
• Cost/time saving for retrofits

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
