In heavy industrial operation, not only output but also the drive’s ability to operate long-term with controlled losses and stable thermal reserve is decisive. The H27R 5603-6-6 model with an output of 2240 kW is intended for applications where a 1000 rpm electric motor is combined with requirements for high reliability, precisely defined load and economical operation with a 6000 V power supply.
This design belongs to the H27R-HD-Modular series and uses a closed IC611 cooling system that keeps the inside of the motor separated from surrounding contamination. Combined with IE4 efficiency, this provides an advantage when operating in dusty, humid or corrosive environments where energy balance and thermal stability translate into total operating costs.
Efficiency and cooling for continuous industrial load
H27R 5603-6-6 is a high-voltage electric motor intended for high-voltage industrial drives where long-term operation without unnecessary thermal fluctuations is expected. The closed IC611 cooling circuit with a heat exchanger helps protect active components from aggressive surroundings while supporting stable removal of losses at continuous output.
- The design with a shaft height of 560 mm is suitable for large technological units with demanding space and torque allocation.
- Efficiency of 95,9 % supports economical operation at high hourly outputs.
- Power factor of 0,89 contributes to more efficient use of the power-supply system.
- Insulation class F and temperature rise class B provide reserve for long operating cycles.
- VPI impregnation of the stator winding increases resistance to moisture, dust and vibration.
Starting and torque reserve for large drives
When designing power supply and protection, the accompanying dynamic profile is also important. Starting torque reaches 0,8 times the rated torque, breakdown torque 2 times the rated torque and starting current 5,8 times the rated current, giving the designer a basis for setting switching components, protection and mechanical linkage to the load.
- Rated current of 252,5 A is an important value for sizing supply fields and cable routes.
- Rated torque of 21521 Nm provides substantial reserve for demanding process loads.
- Rated speed of 994 rpm is suitable for large drives requiring a stable operating mode.
- Rotor inertia of 132,0 kg·m² helps when evaluating starting transients.
- Load inertia of 2590,0 kg·m² is essential when designing the entire drive system.
Use in equipment with high operating loads
In practice, this 6-pole electric motor is used in machines where robust mechanical linkage, precise sizing and continuous operation are required. DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 support operation in heavy conditions, while package weight of 8100 kg reflects the robustness of the assembly prepared for industrial use.
Typical applications include main blowers in steelworks, main cooling-circuit pumps, fans for combustion and filtration systems, compressor units in chemical production, raw-material processing mills, belt conveyor units in mining technology, mixing stations in the paper industry, drainage pumps in power generation and drives for process line transmissions in large factories.
Technical support for integration into existing units
When integrating into switchboards and automation systems, it is essential that the drive fit the existing architecture without unnecessary compromises. The H27R-HD-Modular series is therefore suitable for projects requiring long-term operational reliability, efficient cooling and emphasis on energy balance in the HV electric motor category.
With this series, VYBO Electric emphasizes usability in real operations where efficiency, thermal resistance and mechanical durability must combine into one reliable unit. If you need a solution for a large process unit, order H27R 5603-6-6 as soon as possible and take advantage of fast availability before the next planned technology shutdown.
