High-voltage electric motor 250 kW, 987 rpm, 6 000 V, H17R 355-A-6-6

IE4 efficiency for economical operation of a 1000 rpm electric motor

The H17R 355-A-6-6 model with an output of 250 kW is designed for operations where stable energy consumption and long-term operating discipline are expected from every drive. In this class, it is suitable as a 1000 rpm electric motor for technologies with high inertia, where smooth starting and a predictable load balance are important. IE4 Super Premium efficiency translates into lower losses during continuous operation and better management of the energy balance across the entire line.

VYBO Electric supplies solutions adapted to the real requirements of large factories and OEM integrators. This is precisely why this high-voltage electric motor is suitable wherever long service life, fewer unnecessary shutdowns and consistent output under continuous load are monitored. Operators obtain a drive that performs in technologies with demanding starting profiles as well as systems with long operating cycles.

Compact 6000 V electric motor for space-constrained technologies

A shaft height of 355 mm allows this 6000 V electric motor to be integrated into assemblies where efficient use of the existing installation envelope without compromising power transmission is decisive. The design is suitable for solutions in which a compact 6 kV motor must operate in a robust frame while retaining reserve capacity for demanding operation. Such a version assists with modernization of switchgear and technological units where precise connection to the original mechanics is required.

Voltage-level selection is also important when designing new assemblies. This motor can be included in systems with values of 3 300 V, 6 000 V, 10 000 V or 11 000 V according to grid requirements and the drive concept. This flexibility simplifies standardization in OEM manufacturers’ portfolios as well as repeated applications within one plant.

HV electric motors for continuous load and precise integration

In the HV electric motors category, this solution uses a design suitable for pumping stations, compressor nodes and conveying systems with high utilization. H17R Compact PRO-HV is suitable in this segment for applications requiring reliable torque transmission during long-term operation. A rated speed of 987 rpm together with rated torque of 2419 Nm provides an operating basis for technologies with even load.

Copper strip in the rotor cage is also practically important, supporting mechanical durability during repeated operating states. 6322-C3 bearings on both the DE and NDE sides create the conditions for stable rotor support, while a moment of inertia of 8,7 kg·m² assists in applications requiring balanced starting. Insulation class F and temperature rise B are selected so that the drive can handle industrial use with an emphasis on thermal reserve.

Accessories for drive monitoring and protection

In large technological units, readiness for diagnostics and thermal monitoring is also important. For this motor, 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 thermistor are available, simplifying integration into control and safety schemes. Such equipment supports faster assessment of drive condition during operation and helps plan service interventions before an unwanted shutdown occurs.

Rewinding, bearings and power in service of production lines

This 6-pole electric motor is suitable for mixing lines, rolling units, fan stations, process pumps, crushing systems and extraction systems in heavy industry. In each of these applications, the ability to maintain the process in a stable mode without excessive speed fluctuations and without unnecessary losses in the transmission system is decisive. A weight of 3255 kg also reflects the robust design, which is suitable for fixed foundation installation and long-term operation.

A power factor of 0,85 and efficiency of 95,1 % are also important in drive design because these values enter into calculations of the power supply system, protection sizing and assessment of the overall operating balance. A starting current ratio of 4,6 % together with a starting torque ratio of 0,8 % and a breakdown torque ratio of 1,9 % create a framework for applications where motor behaviour during starting and load changes is monitored.

VYBO Electric for large industrial units with a clear operating objective

Within the VYBO Electric portfolio, this model is suitable wherever energy efficiency, robust mechanical design and the option to adapt the voltage level to a specific operation must be combined. For operators of large factories as well as OEM manufacturers of technological assemblies, a predictable service regime that does not burden the production plan with unplanned shutdowns is important. This 1000 rpm electric motor is therefore also suitable for modernization projects in which technical compatibility is compared with long-term operating costs.

If your project requires a high-voltage solution with an emphasis on efficiency and stability, order H17R 355-A-6-6 in good time. Availability and fast logistics make it possible to shorten the time between specification and installation, which is decisive for large technological units.
