The design of H27R 4003-6-6 is intended for energy-intensive drives where stable output, low losses and long-term operational reliability are decisive. This 1000 rpm electric motor with an output of 560 kW, rated current of 66,3 A and power factor of 0,86 provides parameters suitable for large technological units where efficiency has a direct impact on operating costs.
Energy savings during continuous operation
The H27R-HD-Modular series uses efficiency of 94,9 %, which helps reduce energy losses under load during long production cycles. For operators of large factories, this means a better ratio between delivered output and consumption, especially for drives with a high number of operating hours.
- Rated torque of 5397 Nm supports reliable starting even under higher load.
- Starting torque reaches 0,9 times the rated torque, breakdown torque 2 times the rated torque and starting current 5,4 times the rated current for correct starting and protection design.
- Package weight of 2895 kg corresponds to a robust solution for industrial installations.
IC611 air-to-air cooling for demanding environments
The closed IC611 cooling circuit with a heat exchanger keeps the inside of the motor separated from the surrounding environment, which is beneficial in dusty, humid or corrosive operations. For a high-voltage electric motor intended for a 6000 V power supply, this increases suitability for applications where cleanliness of the internal environment is important for stable insulation and bearing life.
VPI winding impregnation for stable operation
The stator winding is impregnated using VPI technology, which increases resistance to vibration, moisture and dust. This feature supports longer operational reliability in drive technology where continuous load and repeated thermal cycles are expected.
Design details for large technological units
This 6-pole electric motor uses a 400 mm frame size, insulation class F and temperature rise class B, providing a suitable foundation for stable operation in industrial assemblies. The rotor has an inertia of 24,4 kg·m² and the design of the operation must also account for load inertia of 796,0 kg·m² so that the drive is correctly matched to starting and control.
- DE bearing 6326-C3 supports reliable mounting on the drive side.
- NDE bearing 6326-C3 increases consistency of mounting on the opposite side.
- Rated speed of 991 rpm is suitable for large process units.
Use in industrial technologies
H27R 4003-6-6 is used in crushers, mills, fans, blowers, compressor assemblies, heavily loaded conveyors, mixers, extruders, pumps for water-treatment plants, desulfurization units, linear transport systems, rolling stands, pressing lines, granulators, turbo fans and drives for process agitators. For OEM manufacturers and large operations, it is a solution that supports long-term integration into technological units requiring stable output and low operating losses.
Solution ready for practical deployment
With IE4 efficiency, compact construction and robust cooling, H27R-HD-Modular is a suitable choice for modernization and new projects alike. If you need a high-power drive with emphasis on reliability, order the H27R 4003-6-6 model today to avoid delays in delivery and installation planning.
