H27R 4001-2-6 is designed for operations where every percentage point of efficiency has a direct impact on energy costs and technology availability. This 2900 rpm electric motor with an output of 560 kW delivers stable performance for demanding industrial systems where long-term operation, high loading and precisely controlled integration into the drive assembly are expected. Use in the 2900 to 3000 rpm class corresponds to applications focused on high productivity, while efficiency of 96,1 % helps limit energy losses during continuous operation. A power factor of 0,9 also simplifies sizing of the power supply and compensation in extensive production lines.
Energy savings in high-power drives with a 2900 rpm electric motor
In segments where results are determined at the level of megawatt-class drives, IE4 Super Premium efficiency has direct economic importance. With this model, more electrical energy is converted into useful mechanical power, which is especially advantageous in operations with long daily cycles, high utilisation and strict pressure to optimise operating costs. Thanks to rated torque of 1792 Nm, the motor provides sufficient reserve for technological loads, while starting torque reaches 0,8 times the rated torque, breakdown torque 2,7 times the rated torque and starting current 6,7 times the rated current. Such behaviour is important when designing protection, starting and sizing of power-supply components.
Frame design that simplifies handling and installation
The welded steel frame provides a practical benefit both in production and during installation of large machines. Compared with heavier solutions, it enables easier handling, maintains high rigidity and supports precise seating in the drive assembly. Rotor inertia of 6,7 kg·m² and load inertia of 53,0 kg·m² must be taken into account when designing the start-up, coupling diameters and overload protection settings. 6319-C3 bearings on both the DE and NDE sides provide a reliable foundation for long-term operation in demanding service. This two-pole electric motor is therefore suitable for technologies that require a compact, rigid and service-friendly solution.
Standard thermal protection and monitoring for trouble-free operation
In large factories, stability also depends on how well the motor is prepared for temperature monitoring and winding protection. Standard thermal protection and monitoring help reduce the risk of unplanned shutdowns because, at this power class, early information about the motor condition is critical for service intervention and operating planning. Insulation class F together with temperature rise B supports resistance to thermal stress and increases confidence under continuous loading. For integrators in the field of drive technology, it is also important that VYBO Electric builds on solutions suitable for monitoring the winding, bearings and anti-condensation protection.
Technical parameters that support complete drive design
When selecting equipment for OEM projects and modernising production lines, precise data that feed into project documentation and the selection of protective components are decisive. Rated current of 62,6 A, rated speed of 2984 rpm and output of 560 kW define the operating point, while a voltage of 6000 V determines suitable integration into high-voltage infrastructure. A package weight of 2700 kg must be included in logistics, installation and foundation preparation. The result is a solution that fits technologies requiring high continuity of operation and a precisely designed energy balance.
Where this high-voltage motor delivers the greatest benefit
For industrial operations, H27R 4001-2-6 is particularly suitable where high power density, reliable long-term operation and favourable operating costs are required. Typical applications include:
- Main blowers in cement plants with continuous airflow control.
- Process pumps in the chemical industry with high availability and stable loading.
- Compressor units in power generation and gas processing.
- Crushers and mills in mining and stone-processing operations.
- Rolling and conveying lines in metallurgical plants.
- Large mixing systems in the paper and pulp industry.
- Ventilation systems and extraction units in heavy production halls.
A solution for reliable long-term operation
If you are looking for a motor for heavily loaded technology, this model provides a combination of efficiency, rigid construction and practical readiness for integration into larger systems. Thanks to a precisely defined operating point, high efficiency and robust design, it is suitable for modern manufacturing and energy projects where the drive must operate reliably and economically.
