High-voltage electric motor 1800 kW, 994 rpm, 6000 V, IC611, H27R 5601-6-6

H27R 5601-6-6 brings high efficiency, stable operation and reserve for continuous duty to large industrial drives. This 1000 rpm electric motor with an output of 1800 kW operates at a voltage of 6000 V and a rated speed of 994 rpm, making it suitable for applications where low energy losses and long-term operational reliability are monitored. In the category of HV electric motors, it is a solution for demanding operations where thermal stability, precisely defined torque and environmental resistance are decisive.

Economical operation under high load and low losses

The H27R-HD-Modular series uses a concept focused on long-term energy savings and mechanical reliability. Efficiency of 95,9 % together with a power factor of 0,88 supports economical operation in heavy process and power drives, where every percentage point of loss translates into operating costs. This six-pole electric motor is therefore suitable where a balanced ratio between output, network stability and reliable transmission of torque of 17294 Nm is important.

Starting parameters also help when designing the drive, facilitating sizing of the power supply, protection and mechanical reserve. Starting torque reaches 0,8 times the rated torque, breakdown torque 2,1 times the rated torque and starting current 5,7 times the rated current. Rated current is 205,9 A, allowing more precise setting of starting components for large technologies with high inertia. Rotor inertia of 107,0 kg·m² and load inertia of 1990,0 kg·m² confirm that this is a drive intended for massive mechanical systems.

IC611 air-to-air cooling keeps the inside of the motor clean

H27R-HD-Modular motors are equipped with IC611 air-to-air cooling, which supports a closed cooling circuit and helps keep the air inside the machine clean. This solution increases suitability for dusty, humid and corrosive operations where protection of active components from the surroundings and stable heat removal from the motor core are important. Combined with IE4 Super Premium efficiency, the amount of heat generated during energy conversion is reduced, which is especially beneficial under continuous load.

The stator winding uses VPI impregnation of the stator winding, which strengthens resistance to moisture, dust and vibration. This design solution extends the life of the electrical insulation and helps maintain motor parameters during demanding starts, frequent load changes and long-term vibration. Insulation class F combined with temperature rise class B provides favorable reserve for high-power use in technologies where a long operating cycle is expected.

Bearings and design prepared for long-term loading

The motor design uses DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3, which are suitable for robust industrial applications with high mass and stable radial and axial guidance. Package weight of 7500 kg reflects the massive design commonly used in large process units where rigidity and reliable mounting of the rotating system are important. In such applications, the advantage of closed cooling is fully apparent even in operations with higher dust levels or more aggressive atmospheres.

Use in heavy industry and power generation

H27R 5601-6-6 is suitable for equipment requiring reliable output and long service life under heavy loads. Within drive systems, it is used in both steady and variable operating modes where high efficiency, good thermal management and easier integration into existing technological units are expected. For the operator, this means a lower risk of unplanned downtime and better cost predictability.

Typical applications include:

• Main pumps in power-generation units.
• Fan stations for process and cooling circuits.
• Compressor units in the gas industry.
• Mills and crushers in cement production.
• Drive for conveyor lines handling bulk materials.
• Mixing and homogenization units in the chemical industry.
• Exhaust fans in metallurgical operations.
• Rotary dryers in mineral processing.
• Vacuum systems for process technology.
• High-load extrusion lines.
• Auxiliary rolling drives in metallurgy.
• Pumps for water management and desalination.
• Units for paper machines and winders.
• Drives for large screw and paddle conveyors.

Why this model is suitable for continuous operation

In heavy industry, the combination of efficiency, cooling and electrical reserve is decisive. H27R 5601-6-6 combines these characteristics into a single solution that can operate reliably over long cycles and under higher loads without unnecessary energy waste. For operations looking for a solution in the HV electric motor class, it is important that the design supports stable thermal conditions while keeping the motor interior protected from external contaminants.

With this series, VYBO Electric has long focused on parameters that have a real impact on operation, not just catalogue figures. If you need a drive for a technologically demanding unit where high reliability and efficient cooling are expected, order H27R 5601-6-6 as soon as possible so that you can plan installation without delay and with confidence in availability.
