High-voltage electric motor 710 kW, 2981 rpm, 6 000 V, H17R-400-D-2-6

The H17R-400-D-2-6 design is intended for energy efficiency in drives where stability, continuity and long-term operating economy are decisive. The 3000 rpm electric motor at this output of 710 kW meets the requirements of large production lines, pumping stations and technological systems that operate continuously. In practice, it is a solution for factory operators and OEM manufacturers who need a reliable high-voltage electric motor with reserve for demanding cycles.

IE4 Super Premium efficiency reduces energy losses during long-term deployment and helps keep operation under control even where every draw is monitored. In this category, the 6000 V electric motor performs particularly well in higher-load applications because it fully uses the frame space while retaining suitable dimensions for integration into the technology. The power supply is also addressed, as the motor is available for several network levels and allows the project to be adapted to existing infrastructure without unnecessary modifications to the distribution system.

3000 rpm electric motor for stable operation of high-voltage drives

Rated torque of 2275 Nm and rated current of 78,5 A provide the basis for smooth power transmission in processes where uniform running without unnecessary fluctuations is expected. A starting-current ratio of 7 % and breakdown-torque ratio of 3 % give the design predictable behaviour during starting and under load, which is important on lines with sensitive technological interdependencies. A high-voltage electric motor designed in this way is suitable for both central and direct drive.

Compact 6 kV motor for high output in limited space

The 400 mm frame size supports compact motor installation in assemblies where available space in the machine room or a separate drive module is monitored. Even in this construction class, the output potential required by pumps, compressors or mills is retained, so the 3000 rpm electric motor can also be used where higher power density is combined with a requirement for mechanical durability. For the designer, this means easier integration into an existing assembly.

Voltage selection for 3 300 V, 6 000 V, 10 000 V and 11 000 V networks

The ability to adapt the voltage version makes deployment in plants with different distribution levels easier and reduces the need for compromises when designing the HV drive. In this way, VYBO Electric supports solutions for various industrial environments where the 3000 rpm electric motor is assessed not only by output but also by compatibility with the power-supply system. This approach helps OEM manufacturers standardise multiple variants of one technological system.

Overview for design and maintenance in HV operations

H17R Compact PRO-HV is sized with an emphasis on operating reliability appreciated by teams responsible for technical maintenance and long service intervals. Insulation class F, temperature rise B and a weight of 3950 kg create a robust basis for stable operation in environments with increased thermal-load requirements. Rotor moment of inertia of 5,300 kg·m² supports balanced dynamic behaviour during starting and when the operating mode changes.

DE bearing 6319-C3 and NDE bearing 6319-C3 increase the mechanical durability of the assembly during long-term running. The rotor cage made of copper strip contributes to favourable electrical and thermal behaviour, which is important under frequent load and in operation with a higher number of starts. The 2-pole electric motor principle remains suitable for applications requiring high speed and direct connection to the technological process.

Accessories including 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistors support condition control during operation and simplify integration into monitoring systems. Combined with efficiency of 96,1 % and a power factor of 0,91, the motor is suitable for projects where energy balance, reliability and long-term operating discipline are monitored. VYBO Electric is the largest company in its sector in Central Europe.

Applications for pumps, compressors and technological systems

The motor is used in cooling-water pumps, centrifugal compressors, fans for drying lines, blowers for incinerators, mixers in chemical production, rolling stands, extruders, conveyors for bulk materials, mills in cement plants, crushers in stone processing, flotation systems in ore processing, dewatering stations, engineering test rigs and drives for process pumps in petrochemical operation.

Energy operation with an emphasis on long cycles

During long-term deployment, it becomes clear that not only output matters, but also the ability to keep operation within a stable thermal and electrical regime. This high-voltage electric motor is therefore suitable for teams dealing with production reliability, planned shutdowns and electrical-energy costs over the entire equipment life cycle. With a drive designed in this way, the technology behaves predictably and service teams have better support from diagnostics and monitoring.
