The H27R 5601-2-6 design is intended for large drives where long-term stability, sensible operating costs and high operating efficiency are decisive. This 3000 rpm electric motor with an output of 2240 kW, rated current of 241,8 A and a power factor of 0,92 is suitable wherever equipment must operate smoothly with minimal energy losses. With a 6000 V power supply, it provides a power foundation for heavy process technologies requiring reserve even under variable loading.
Greater energy utilisation in continuous operation
For energy-intensive operations, not only the rated value but also how the motor processes electrical energy during long working cycles is important. IE4 Super Premium efficiency supports lower losses at high outputs and helps maintain a favourable consumption balance in plants where pumps, fans, compressors or technological lines operate without interruption. In practice, this means lower thermal loading, more efficient drive operation and better scope for planning operating costs.
Cooling that protects internal motor components in demanding environments
The closed cooling circuit with an IC611 heat exchanger keeps the air inside the motor separated from the surrounding environment, which helps in dusty halls, metallurgical operations and locations with increased corrosive exposure. This solution supports cleanliness inside the machine and improves conditions for long-term reliability. VPI impregnation of the stator winding also strengthens resistance to moisture, dust and vibration, which is a significant benefit in heavy industry.
Starting and mechanical reserve for large technologies
When designing the power supply and protection, it is important to account for starting torque reaching 0,5 times the rated torque, breakdown torque 2,4 times the rated torque and starting current 5,6 times the rated current. These data help when sizing starting components, protection and connection paths. Rotor inertia of 37,0 kg·m² and load inertia of 139,0 kg·m² are important in applications where start-up dynamics and the overall mechanical loading of the system are monitored. Both DE and NDE bearings are available on request according to project requirements.
Typical use in heavy industry
The motor is used in applications where reliability, long running periods and stable operation are important. This two-pole electric motor is suitable for:
- Main pumps in power-generation units.
- Fans for combustion and extraction systems.
- Compressors for process compressed air.
- Mill drives in the cement industry.
- Agitator drives in chemical operations.
- Extruder lines in polymer processing.
- Rolling and transport systems in metallurgy.
- Crushers in mining and mineral processing.
- Centrifugal separators in large production systems.
- Counterflow and process fans in paper mills.
- Drives for drying and filtration technologies.
A solution for operators monitoring both costs and reliability
Thanks to the combination of high efficiency, robust cooling and a design for demanding deployment, this model is suitable for high-voltage industrial drives where long service life and stable output are expected. For projects that need to connect precisely to existing technology or modernise an older drive, it provides a reliable foundation with good scope for technical adaptation.
If you need a motor for a large production system, order H27R 5601-2-6 in good time so that the delivery date and installation plan are ready without unnecessary downtime.
