The design of the H27R-HD-Modular series is prepared for large drives where stable operation, reasonable operating costs and long service life are decisive. The H27R 5602-8-6 model with an output of 1600 kW is among the solutions that, in the 700 rpm electric motor class, provide operating reserve for continuous load while maintaining high efficiency of 96,1 %.
The welded steel frame provides high rigidity while also facilitating handling of the large motor during transport and installation. The closed cooling system with IC611 air-to-air cooling keeps the motor interior separated from the surroundings, which is beneficial in dusty operations, metallurgy and areas with corrosive exposure.
Energy savings under continuous load
During long-term operation, a power factor of 0,85 together with rated current of 189,1 A helps reduce demands on the power supply and distribution sizing. For the operator, this means better control over losses and less pressure on infrastructure, which is important in equipment where the energy efficiency of the entire technological unit is also monitored.
Resistance for heavy industry
This high-voltage electric motor uses insulation class F and temperature rise class B, so the design includes thermal reserve for demanding duty. The rotor cage made of copper strip supports lower electrical losses, improves thermal resistance and helps maintain long service life during repeated starts and high loads.
The basic starting characteristics are suitable for designing both protection and the power-supply system. Starting torque reaches 0,7 times the rated torque, breakdown torque 1,8 times the rated torque and starting current 4,7 times the rated current, which is important when assessing torque reserve in technologies with higher inertia.
Bearing durability and stability at high inertia
A rotor with inertia of 175,0 kg·m² and a load with inertia of 3540,0 kg·m² require precisely designed starts and sensitive control of operating conditions. DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 are selected so that shaft support remains stable even during long-term industrial use.
Technical parameters for drive design
The H27R-HD-Modular series is suitable for designers who need to combine high output, reliability and space-intensive integration into existing lines. A package weight of 7750 kg corresponds to the class of large machines where it is worthwhile to plan handling and service intervention already at the project stage.
Industrial use in heavy-duty operations
The H27R 5602-8-6 model is suitable for the following applications:
- Drives for large centrifugal compressors in power generation.
- Main drive units for raw-water pumps.
- Fan units in cement-production lines.
- Compressor stations for gas processing.
- Rolling stands in metallurgical operations.
- Mills for crushing and grinding ore.
- Drives for conveyor systems in mining.
- Process agitators in the chemical industry.
- Unit cooling towers for large factories.
- Complex vacuum pumps in the paper industry.
- High-load extrusion lines.
- Power consumers in plants with continuous operation.
If you are looking for a robust motor for long-term load while also wanting the benefits of a welded frame, efficient cooling and a copper rotor cage, take advantage of the offer of a VYBO Electric solution for your project.
A three-phase electric motor of this class provides large technologies with a stable foundation that can be relied on when planning both operation and servicing.
H27R 5602-8-6 is designed for reliable operation in environments where long service life, precisely defined starting behavior and construction prepared for demanding conditions are valued.
