In power generation, metallurgy and heavy production lines, stable operation determines costs, outages and the service life of the entire technology. The H27R 5004-2-6 model delivers an output of 2000 kW for applications where long-term loading, high efficiency and precise drive reserve without unnecessary downtime are expected. In practice, it helps reduce costs mainly by maintaining efficiency of 96,9 % and a power factor of 0,91 within the operating range that is decisive for large process systems.
2900 rpm electric motor for large technological systems with lower operating losses
This 2900 rpm electric motor belongs to a category where continuous operation, high mechanical stability and service confidence are expected. The 500 mm frame size supports robust mounting of active components, while the welded steel frame reduces the weight burden during handling compared with heavy cast-iron solutions, simplifying installation in confined areas and replacement on the line.
Closed IC611 air-to-air cooling keeps the motor interior separated from surrounding contamination, so the drive handles dusty, humid and corrosive environments more effectively. When designing the power supply, a rated current of 211,4 A and starting current of 7,1 times the rated current must be taken into account so that circuit breakers, contactors and substation protection are set correctly.
Design that helps handle high torque loading
The mechanical section is designed for high torque of 6390 Nm and for applications where the load changes the dynamics of starting and stopping. Starting torque reaches 0,7 times the rated torque and breakdown torque 3 times the rated torque, which is important when assessing torque reserve in transmissions, pumps, conveyors and crushing technologies. Copper rotor bars contribute to low losses and improved thermal behaviour under long-term loading.
A safe choice for power supply and protection
Insulation class F together with temperature rise B gives the operation the required thermal reserve under stable loading. Rotor inertia of 28,0 kg·m² and load inertia of 136,0 kg·m² are also important for designers because these values directly affect unit starting, coupling sizing and the method of start control in large machines. This two-pole electric motor is therefore suitable for operations where precise coordination of the electrical and mechanical sections is required.
Industrial applications with high operating confidence
In practice, this high-voltage electric motor is used especially where long service life, environmental resistance and reliable power transmission are important. VYBO Electric prepares solutions for high-voltage industrial drives and high-power segments, while this model is designed for demanding deployment in the following areas:
- Main pumps in power-generation units and water-supply stations.
- Fan units for boiler rooms, filters and process extraction.
- Heavily loaded conveyors in the mining and cement industries.
- Crushers, mills and mixing technologies with variable loading.
- Compressor stations in chemical and petrochemical production.
- Process lines in metallurgy and raw-material processing.
Service availability and technical design for a long life cycle
The DE bearing is available on request and the NDE bearing is available on request, allowing the final arrangement to be adapted to the specific project and service strategy. A package weight of 5880 kg corresponds to the size and robustness of the assembly, so handling, lifting points and logistics should be planned before dispatch. If you need a drive for continuous loading where efficiency, cooling and mechanical stability are decisive, take advantage of the offer and select a solution with VYBO Electric support.
