In operations where continuous output and cost control are decisive, H27R 4002-6-6 provides a precisely targeted solution for heavy technological units. This 500 kW electric motor for 6000 V and a rated speed of 991 rpm is designed to help reduce energy losses under long-term load while maintaining stable operation in demanding industrial processes.
The H27R-HD-Modular series uses a concept that combines high efficiency with robust mechanical durability. IE4 Super Premium efficiency supports economical operation under high load, while the welded steel frame provides high rigidity with a favorable package weight of 2800 kg. Such a solution facilitates handling during installation while helping maintain precise geometry even in demanding conditions. In a category where every percentage point of efficiency counts, this is a practical benefit for both energy audits and long-term drive reliability.
900 rpm electric motor for economical operation of high-power lines
Industrial units operating continuously require a solution that handles thermal load, dynamic changes and service-availability requirements well. This 6-pole electric motor is therefore suitable for assemblies where a balanced combination of torque, efficiency and resistance to long-term stress is important. Rated torque of 4818 Nm together with rated current of 59,3 A creates the conditions for reliable power transmission in technologies with high inertia.
- Rated speed of 991 rpm is suitable for drives requiring smooth and stable working speed.
- Power factor of 0,86 supports efficient use of the network in large motor assemblies.
- Efficiency of 94,8 % helps limit operating losses under long-term load.
- Insulation class F and temperature rise class B provide reserve for demanding thermal conditions.
Preparation for motor starting and protection is also important in practice. Starting torque reaches 0,9 times the rated torque, breakdown torque 2,1 times the rated torque and starting current 5,7 times the rated current, which helps when designing the power supply, protection and mechanical reserve for loaded technologies. Rotor inertia of 22,0 kg·m² and load inertia of 706,0 kg·m² are relevant when sizing the run-up of conveyors, mills or compressor assemblies.
Technical equipment for reliability in continuous production
At this output, H27R-HD-Modular is suitable for environments where high availability and easier integration into the technological unit are expected. The series uses standard thermal protection and monitoring, which improves supervision of the winding and bearings and supports early diagnosis of operating condition. Combined with suitable IC611 cooling, the motor performs well in applications where long-term stability without unnecessary downtime is required.
- PT100 sensors in the winding and bearings support precise temperature monitoring.
- PTC thermistors improve protection under thermal stress.
- Anti-condensation heating with a 230 V power supply helps limit moisture during shutdowns.
- 6326-C3 bearings on both the DE and NDE sides contribute to reliable operation in large high-power assemblies.
Use in seven typical industrial applications
In practice, a three-phase electric motor of this type is used, for example, in cement mills, large pumping stations, extraction fans for metallurgical operations, belt conveyors for heavy raw-material transport, aggregate crushers, compressor units for process gas and mixers for chemical production. It is precisely in these high-voltage industrial drives that the combination of efficiency, mechanical stability and suitable torque reserve is fully utilized.
Solution for large high-voltage drives
For OEM manufacturers and plant operators, it is important that the motor fits into the design without compromises in electrical or mechanical parameters. H27R 4002-6-6 therefore provides a consistent basis for drive design where long service life, controllable losses and high operational reliability are expected. Combined with the VYBO Electric brand, it is a solution prepared for modern energy-intensive operations.
