H27R 5001-8-6 is a 700 rpm electric motor designed for an output of 900 kW and a 6000 V power supply, while at a rated speed of 744 rpm it provides operation with lower energy losses in demanding technological nodes. This three-phase electric motor is intended for stable operation in the category of large HV drives where long-term economy, thermal reserve and reliable power transmission are decisive.
IE4 efficiency reduces losses during continuous operation of a 700 rpm electric motor
IE4 Super Premium efficiency helps limit operating losses in high-power applications where every percentage point of efficiency is reflected in consumption and the thermal conditions of the entire drive. Combined with a welded steel frame, the motor design has higher rigidity, favorable weight efficiency and better handling during installation of large assemblies.
- High efficiency supports economical operation of pumps, compressors and transmission units.
- The welded frame improves mechanical resistance under continuous load and vibration from the technology.
- Rated current of 106,9 A facilitates the design of power-supply and protection components in the HV switchboard.
Torque reserve and starting help under heavy loads
In this 8-pole electric motor, rated torque is 11552 Nm, providing sufficient reserve for both starting and steady operating conditions of large production lines. Starting torque reaches 1 times the rated torque, breakdown torque 2,1 times the rated torque and starting current 5,6 times the rated current, so the design of starting, protection and the supply branch can be based on a precise load assumption. Rotor inertia of 90,0 kg·m² and load inertia of 1850,0 kg·m² are particularly important in assemblies with high stored energy.
In this output class, a power factor of 0,85 is also useful, helping optimize the design of the plant’s power-supply infrastructure. For operators of large factories, it is also practical that temperature rise class B together with insulation class F provides suitable thermal and insulation reserve for long-term duty.
Standard thermal protection and monitoring increase operational reliability
The H27R-HD-Modular series uses standard thermal protection and monitoring that facilitate supervision of the winding and bearings during critical operating modes. In practice, this solution supports early detection of overload, thermal fluctuations and conditions that can shorten machine life.
- Temperature sensing in the winding and bearings helps detect deviations from normal conditions in time.
- Anti-condensation heating supports machine readiness after shutdowns and during environmental fluctuations.
- DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 correspond to the demanding operating class.
Applications in highly reliable technology
H27R 5001-8-6 is used in raw-water pumping stations, large process pumps, compressor stations, blowers for power generation, cement mills, rolling mills, high-inertia conveyors, mixers for the chemical industry, extrusion lines, paper winders, cooling-tower fans, crushers, flotation in mining and water-treatment technological units. In each of these applications, a three-phase electric motor is expected to provide stable operation, straightforward sizing and long service life under load.
With the H27R-HD-Modular series, VYBO Electric combines a technical solution for high-voltage industrial drives with the practical requirements of OEM projects where efficiency, mechanical rigidity and predictable servicing are decisive.

Quick overview of parameters
Rated output of 900 kW, voltage of 6000 V, speed of 744 rpm, current of 106,9 A, efficiency of 95,7 %, power factor of 0,85, frame of 500 mm and package weight of 5110 kg form a robust basis for designing a large drive. Bearing, inertia and torque data also help when designing the machine because they enable more precise assessment of starting, loading and the overall energy balance of the line.
