The design of the H27R 5601-4-6 motor with an output of 2240 kW is intended for large drives where long-term operational reliability and lower maintenance costs are decisive. This high-voltage electric motor operates at a voltage of 6000 V and a rated speed of 1493 rpm, making it well suited to operations that require stable output in the 1400-1500 rpm class without unnecessary interventions in the technology. In practice, this means more efficient energy use, lower thermal load and more precise planning of service intervals.
2240 kW electric motor for energy-intensive operations
For large process units, it is worthwhile to monitor not only rated output but also efficiency, current demand and torque reserve during starting. Efficiency of 96,1 % and a power factor of 0,91 help limit losses during long operating cycles, which is especially important for equipment with high hourly costs. Rated current of 246,5 A is suitable for the design of power supply, protection and surge protection in systems intended for long-term load.
Starting behavior is also important when designing the starting system and ensuring torque transmission. Starting torque reaches 0,7 times the rated torque, breakdown torque 2,3 times the rated torque and starting current 6,3 times the rated current, which helps when selecting contactor or frequency-converter coordination and sizing network protection. Rated torque of 14328 Nm provides sufficient reserve for heavy technological units with impact loads.
Welded steel frame simplifies handling and installation
The main structural benefit is the welded steel frame, which provides high rigidity for a large machine while helping reduce weight compared with cast-iron solutions. This is reflected in transport, placement on the foundation and precise alignment with the machine connected to the motor. For the operator, this means shorter installation time and simpler logistics during replacement or major servicing.
Equally important is IC611 air-to-air cooling, because the closed cooling circuit keeps the air inside the motor clean and improves suitability for dusty or corrosive environments. In heavy industry this is a practical benefit, as the internal components are better protected from contamination and operation remains stable even under increased environmental demands.
Structural elements for long service life in demanding operation
The rotor cage made of copper strip supports lower electrical losses and helps handle thermal stress during long duty periods. Combined with insulation class F and temperature rise B, it creates the conditions for reliable operation in demanding technological cycles. Rotor inertia of 70,0 kg·m² and load inertia of 805,0 kg·m² should be taken into account when calculating starting and selecting the coupling, gearbox or soft starter.
The bearing arrangement is designed with long-term loading in mind, with the DE bearing being NU238-C3+6040-C3 and the NDE bearing NU230-C3. This solution supports shaft stability during operation and simplifies service planning in large production units. Package weight of 7800 kg must be taken into account during crane handling, transport and preparation of the installation area.
Typical use in industrial technologies
This four-pole electric motor is suitable where continuous output, high availability and precisely defined operating conditions are required. Thanks to its design and parameters, it is suitable for extensive lines and units in heavy industry, power generation and processing operations where emphasis is placed on service life and predictable servicing.
It is most commonly used in the following applications:
- Compressors for large technological units in petrochemical production.
- Pumping stations for cooling and process water in power generation.
- Conveyor systems with high starting torque in mining.
- Mills and crushers in the cement and metallurgical industries.
- Ventilation units and blowers for large industrial operations.
- Rolling and winding units with impact loads in metallurgy.
In environments using HV electric motors, compatibility with the plant’s protection and control systems is also important, so this model helps simplify integration into existing technologies. If you need a solution for a large drive with emphasis on reducing operating costs, take advantage of the offer and secure a motor that will support long and stable operation of your technology.
