High-voltage electric motor 1600 kW, 2988 rpm, 6000 V, IC611, H27R 5002-2-6

IC611 air-to-air cooling provides lower thermal loading and better operating confidence for high-power drives during long working cycles. The H27R 5002-2-6 model with an output of 1600 kW is designed for applications where reliable dissipation of losses, high efficiency and control of operating costs are decisive. At this power level, a high degree of economy becomes a direct part of drive design rather than merely an additional parameter.

This two-pole electric motor is intended for industrial assemblies that need precise and stable output from a 6000 V supply. Rated speed of 2988 rpm, rated current of 175 A, rated torque of 5114 Nm and power factor of 0,91 provide a balanced basis for sizing converters, protection and power-supply fields. Efficiency of 97 % reduces energy losses and supports long-term operating economy in heavy production.

Energy efficiency in continuous operation

For operators of large factories, it is important for the motor to maintain output even under long daily loading without unnecessary growth in losses. IE4 Super Premium efficiency helps precisely in this respect because it limits conversion of energy into heat and thereby preserves room for stable, economical operation of high-power drives. Drive technology at this scale requires a design that can also handle changing process conditions without reducing reliability.

Winding construction and resistance to the environment

VPI impregnation of the stator winding increases resistance to moisture, dust and vibration, which is beneficial in metallurgy, chemical production and operations with continuous vibration loading. Insulation class F together with temperature rise B provides reserve for long-term thermal loading. A rotor with moment of inertia of 23,5 kg·m² and a load with inertia of 108,0 kg·m² allow the motor to be considered in systems with higher mechanical demands without an unnecessarily narrow design window.

Starting and torque reserve for heavy mechanisms

When designing the start, it is necessary to take into account that starting torque reaches 0,6 times the rated torque, breakdown torque 2,8 times the rated torque and starting current 6,6 times the rated current. Such values are important when sizing switchboards and protective components and when assessing power-supply reserve in networks serving large technological blocks. A package weight of 5440 kg also confirms that this is a motor for heavy industrial deployment where handling and installation are routinely planned before assembly.

For operations with higher air contamination or corrosive environments, a closed cooling circuit with a heat exchanger is a practical advantage because it keeps the air inside the machine clean and helps stabilise long-term parameters. In applications such as crushing lines, conveyor nodes, process-water pumps, compressor stations, fan units, mills, mixing stations and extruder drives, output can therefore be combined more effectively with protection of the motor’s active components.

Deployment in large plants and energy systems

The H27R 5002-2-6 model is used wherever a robust high-voltage electric motor is required for continuous operation and precisely controlled delivery of mechanical energy. Thanks to the design with IC611 air-to-air cooling, it is also suitable for areas where direct contact with process dust or a more aggressive environment would increase service requirements. Combined with the power-supply parameters and IE4-class efficiency, it is a solution that supports long service intervals and predictable operation.

• Metallurgical fan drives for extraction and air circulation.
• Cooling-water pumps in power-generation units.
• Compressor stations for process air.
• Mills in cement and ore processing.
• Crushing lines in the mining industry.
• Mixing and blending units in chemical production.
• Conveyor systems for bulk materials.
• Extruder and rolling drives with high inertial loading.

Service and project considerations

The DE bearing is available on request, as is the NDE bearing, allowing the final solution to be adapted to the requirements of a specific project. During selection, it is advisable to coordinate the mechanical arrangement, starting method, protection and cooling with the load characteristics so that the motor operates within the expected operating range without unwanted losses. For project documentation, it is also important that this 3000 rpm electric motor belongs to a segment where design accuracy translates directly into drive service life.

A solution prepared for immediate project deployment

If your operation requires an output of 1600 kW, a 6000 V power supply and high operating reliability, H27R 5002-2-6 is prepared as a foundation for large process assemblies. Use the combination of efficient cooling, high efficiency and durable winding in a modernisation or new project. Order this motor in good time to minimise downtime during planned technology expansion.
