The H27R 5604-2-6 design is intended for heavy drives where stable output of 3150 kW, high operating confidence and low losses under long-term loading are decisive. This 3000 rpm electric motor operates at a rated current of 338,9 A, reaches efficiency of 97,2 % and a power factor of 0,92, making it well suited to applications focused on energy efficiency and control of operating costs.
IC611 cooling keeps the motor interior cleaner
The closed cooling circuit with an IC611 heat exchanger helps keep the air inside the motor separated from the surrounding environment, increasing usability in dusty, humid and corrosive operations. Combined with IE4 Super Premium efficiency, energy losses in a high-power drive are reduced and the motor maintains its parameters more effectively under continuous loading. VPI impregnation of the stator winding also contributes to higher resistance to vibration, dust and moisture.
- A shaft height of 560 mm supports use in robust installations with large mechanical reserve.
- Rated torque of 10064 Nm supports starting and stabilisation of demanding technological systems.
- Rotor inertia of 50,0 kg·m² and load inertia of 224,0 kg·m² are important when designing drive starting and protection.
- Starting torque reaches 0,66 times the rated torque, breakdown torque 2,9 times the rated torque and starting current 7 times the rated current.
- Insulation class F and temperature rise B support long-term loading in industrial operation.
Industrial deployment in power generation and heavy production
The H27R 5604-2-6 model is suitable for air-compressor stations, large pumping units, furnace fans, extraction systems, agitators in chemical production, ore conveyors, crushers, mills, extruders, heavy-duty mixers, rolling lines, auxiliary turbine drives, desulphurisation units and cooling towers. In these operations, the ability to use a 6000 V supply is also valued because it helps simplify integration into high-voltage distribution systems.
Mechanical integration and service confidence
Both the DE and NDE bearings are available on request, simplifying adaptation of the motor to the specific operation and service strategy. A package weight of 7450 kg reflects the robust design intended for projects demanding in both handling and installation. If you need a motor for continuous processes with an emphasis on efficiency reserve, reliable cooling and long winding life, order H27R 5604-2-6 now to obtain a suitable solution for the next production stage without unnecessary delay.
Technical parameters for drive design
