SIMOTICS HV Series Metall
SIMOTICS HV Series Metall
Overview
General description
SIMOTICS HV Series Metals are rolling mill motors and are used worldwide in the metals industry in rolling mills. Tailored to address particular customer requirements, they are used as main drives in almost all rolling applications and all rolling mill types – in five different types of construction.
Their extremely high smooth running properties and dynamic performance play a decisive role in achieving maximum product quality – even at high power ratings. Their range of power ratings extends from 0.5 MW up to 16.5 MW at speeds of between 20 and 1500 rpm.
For the typical requirements in the rolling mill area – wide speed control range with a constant maximum power – SIMOTICS HV Series Metals motors can provide up to 250% rated torque over the complete speed range without requiring any special measures. The synchronous motors – with cylindrical rotor – can even withstand the highest forces, surge loads and step-like load changes.
In spite of the enormous loads, the motors have a high speed stability and extremely low torque ripple. With 30 to 2460 kNm, the converter-fed motors also cover a wide torque range.

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 |

SIMOTICS HV Series Metals are rolling mill motors and are used worldwide in the metals industry in rolling mills. Tailored to address particular customer requirements, they are used as main drives in almost all rolling applications and all rolling mill types – in five different types of construction.
SIMOTICS HV Series HS-modyn
More than reliable – high-speed high-voltage motors up to 15000 rpm.
The SIMOTICS HV Series HS-modyn sets standards when it comes to the availability of compressor drives: it has the highest degree of reliability and minimum maintenance costs.
SIMOTICS HV Series H-modyn
Individual drive solutions for application and industry sector-specific customer requirements
SIMOTICS HV Series H-compact PLUS
Highest power rating, reliability, efficiency and modular cooling system: This distinguishes the three-phase high-voltage motors of the SIMOTICS HV Series H‑compact PLUS.
SIMOTICS HV Series H-compact
The increasing significance of energy-saving, environmental legislation, the desire for even smaller dimensions and the demands of domestic and international markets have led to the further development of the SIMOTICS HV Series H‑compact that has proven itself over the years.
SIMOTICS HV Series A-modyn
The SIMOTICS HV Series A-modyn of electrical machinery is especially suitable for applications in the areas of power generation, water / wastewater and in the steel industry.
SIMOTICS HV Series A-compact PLUS
It is essential that drive solutions for pumps, fans and compressors are absolutely reliable and cost-efficient. They must also set themselves apart as a result of their first-class quality. This is because the highest degree of availability has topmost priority for these applications
SIMOTICS HV M
Drive power ratings in compressor stations for gas pipelines, gas storage facilities, gas liquefaction plants (LNG) and rolling mills are increasing, and at the same time, the demands relating to plant/system availability and reliability still remain at high levels.
