H27R 5001-2-6 is a solution for operations where stable performance, long service life and lower downtime costs are decisive. This 2900 rpm electric motor with an output of 1400 kW and a voltage of 6000 V is designed for heavy-duty deployment in power generation, raw-material processing and large production lines where reliable operation under high load and efficient performance with efficiency of 96,9 % are expected.
The foundation of the design is the welded steel frame, which gives the large motor high rigidity at a sensible weight while simplifying transport and installation in industrial halls. Closed IC611 air-to-air cooling helps keep the internal airflow clean, which is important where dust, moisture or corrosive environments occur. A high-voltage electric motor from this series therefore fits more effectively into environments where protection of active parts is just as important as the output itself.
2900 rpm electric motor for economical operation of large drives
At a rated current of 153,2 A, power factor of 0,91 and rated torque of 4475 Nm, the motor provides reserve suitable for long technological cycles. For the design of starting, power supply and protection, it is important that starting torque reaches 0,6 times the rated torque, breakdown torque 2,9 times the rated torque and starting current 6,7 times the rated current. These data help correctly size the transformer, switching components and overcurrent protection without unnecessary oversizing.
In practice, this 2-pole electric motor is used to drive rolling lines, compressor units, pumping stations, blast-furnace fans, agitators in chemical production, conveyors in quarries, crushers, mills, grinding equipment, extraction systems, turbine test stations and auxiliary energy drives in large factories. Because these are HV electric motors with high output and a rigid frame, they can also be deployed where long-term operation under stable loading is expected.
Copper rotor bars deliver lower losses and higher thermal resistance
The rotor with copper rotor bars supports low electrical losses and helps maintain good thermal behaviour even under repeated loading. Insulation class F together with temperature rise B provides suitable reserve for demanding applications where long operating periods without frequent downtime are expected. Rotor inertia of 21,2 kg·m² and load inertia of 93,7 kg·m² must be included in calculations for starting, braking and selection of the coupling or gear stage.
Parameters that simplify design and servicing
- Rated speed of 2988 rpm supports stable deployment in the 2900-3000 rpm range.
- Output of 1400 kW enables direct coverage of large process drives.
- Rated current of 153,2 A simplifies power-supply and protection design.
- A package weight of 5200 kg corresponds to a robust industrial design.
- Both the DE bearing and NDE bearing are available on request, simplifying adaptation to the specific project.
If you need a motor for heavy-duty operation with an emphasis on efficiency, service readiness and long-term stability, H27R 5001-2-6 is a practical choice for modern industrial systems. VYBO Electric will help you select a suitable configuration so that you achieve lower operating costs and confidence under continuous loading, so take advantage of the offer and prepare a solution precisely for your technology.
