H27R 5002-4-6 is designed for drives where stable performance, long service life and lower maintenance costs are decisive. This 1400 rpm electric motor with an output of 1600 kW, voltage of 6000 V and rated speed of 1491 rpm helps maintain efficient operation of large technologies with an efficiency of 96,1 % and a power factor of 0,9. In practice, this means lower energy losses, better utilization of the connected grid and more stable operation under long-term load.
The design is based on a welded steel frame, which provides high rigidity while allowing easier handling than heavy cast-iron solutions. The closed circuit with IC611 air-to-air cooling helps keep the internal environment of the machine clean, which is important in dusty operations as well as environments with higher corrosive stress. The rotor cage made of copper strip supports lower losses and thermal resistance, allowing the motor to better handle long production cycles and frequent starts.
Energy efficiency and torque reserve for large drives
For designers and maintenance teams, not only the rated value but also starting behavior is important. Starting torque reaches 0,8 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 6 times the rated current. Such data make it easier to design the power supply, protection and coordination with converters, starting systems and process restrictions. For large factories, the rotor inertia of 56,0 kg·m² and load inertia of 773,0 kg·m², which enter into the calculation of system dynamics, are also important.
Bearing arrangement for a long service interval
The DE-side bearing is NU238-C3+6040-C3, while the NDE-side bearing is NU230-C3. This arrangement supports stability at high output and helps maintain precise shaft guidance in demanding operation. Insulation class F together with temperature rise B creates a reserve for process modes where long-term thermal stress is expected. The package weight of 5760 kg also indicates a robust design suitable for heavy industry.
Use in large technological units
This four-pole electric motor is suitable for demanding applications requiring high reliability, precise operating balance and a long interval between interventions. A high-voltage electric motor of this class is used in operations with continuous as well as intermittent load, where grid stability, space requirements and resistance to the surrounding environment are decisive.
Typical applications include:
- Driving process-water pumps in large power-generation units.
- Driving compressors in petrochemical and refinery operations.
- Air distribution through large blowers in metallurgical lines.
- Main drive for raw-material conveyors in mines and ore processing.
- Driving mills in cement plants with long production batches.
- Driving fans in flue-gas extraction systems.
- Operation of mixers in chemical processing with high torque requirements.
- Auxiliary drive for extrusion lines in polymer processing.
- Driving granulation and crushing equipment in heavy industry.
- Driving large rolling and handling systems.
Operating advantages when integrating into technology
When designing it into an existing operation, you will appreciate the combination of robust construction, efficient cooling and technical parameters that integrate well into protection and control design. The H27R 5002-4-6 model is ready for use where energy efficiency, operational availability and long-term output stability are monitored. If you need a motor for a large technological unit, take advantage of the offer and choose a solution with reserve for demanding industrial conditions.
