High-voltage electric motor 1000 kW, 2989 rpm, 6 000 V, H17R-450-C-2-6

The H17R-450-C-2-6 design delivers compact output for large drives where stability, thermal reserve and precise coordination with the power-supply system are decisive. This 2900 rpm electric motor from VYBO Electric is designed for environments where reliable operation over long operating cycles is expected from the unit without unnecessary disruption to production.

2900 rpm electric motor for highly loaded process lines

In heavy industrial operation, it is particularly suitable where drive technology works with large inertial masses, frequent starts and stable torque. The copper rotor in this assembly limits losses in the winding, handles thermal load more effectively and helps maintain parameters even under long-term load. For the operator, this means a lower risk of unplanned shutdowns and a longer interval between service interventions.

The two-pole concept provides a suitable basis for high speed and smooth power transmission to pumps, compressors or process machines. At the same time, it is a solution that fits well into the operating regime of large factories where repeatable dynamics under stable operating conditions are important.

IE4 efficiency for lower consumption in continuous operation

IE4 efficiency helps reduce operating losses in applications where the motor runs most of the time at a steady operating point. Under such load, the difference is reflected particularly in energy consumption and lower thermal stress on the entire drive. For production plants, this means better use of installed input power and lower cooling requirements for the surrounding space.

A three-phase electric motor in this class is suitable for equipment that must maintain its operating point over the long term without fluctuations and with an emphasis on efficiency in real operation. Compared with less efficient alternatives, it is better suited to systems where energy costs are monitored for every kilowatt-hour and where return is assessed across the entire life cycle.

Frequency selection for European and 60 Hz networks

The option to select the frequency makes deployment easier in plants with different network infrastructure and in export projects where 60 Hz operation is also expected. Such a solution reduces the need for design compromises and makes it easier to standardise drives across global production programmes.

• Centrifugal pumps in chemical production with long daily operating hours.
• Compressor stations for process air in metallurgical plants.
• Vacuum pumps in the paper industry.
• Furnace fans in cement-production lines.
• Main mixers in petrochemical reactors.
• Crushers in stone-processing and mining operations.
• Conveyor drives in port terminals with continuous operation.
• Rotary drying drums in mineral processing.
• Mills for processing raw materials in the energy and construction-materials sectors.
• Equalisation and circulation pumps in large cooling circuits.

Bearing arrangement and temperature monitoring under long-term load

6322-C3 bearings on both the DE and NDE sides support reliable operation under higher mechanical stress and during long operating intervals. For applications with continuous load, the ability to monitor winding and bearing temperatures precisely is also important because the operator gains a better overview of machine condition without the need for complex intervention in the technology.

A high-voltage electric motor designed in this way is suitable for operations where precise coordination with frequency-converter or direct mains supply is expected and where a robust mechanical design is required. Temperature rise class B together with insulation class F provides room for stable operation in demanding conditions.

Industrial deployment with VYBO Electric support

VYBO Electric designs this solution for operations that need a reliable three-phase electric motor with an emphasis on repeatable output, energy efficiency and long-term availability of service support. In practice, operators of large factories looking for a motor suitable for process and energy systems with variable loads will appreciate this.

A weight of 5000 kg and rotor moment of inertia of 6,800 kg·m² confirm that this assembly is intended for fixed base frames and technological nodes with a higher degree of mechanical stability. The rotor cage made of copper strip helps transfer energy into the load while supporting service life under cyclic load.

For projects emphasising safe starting, temperature monitoring and operating discipline, take advantage of the H17R Compact PRO-HV solution from VYBO Electric, which combines a copper rotor for long service life with efficiency suitable for demanding industrial drives.
