In heavy manufacturing, power generation and continuous operations, every percentage point of efficiency and reliability under long-term load matters. The H27R 5004-4-6 model is designed as a robust 1400 rpm electric motor with an output of 2000 kW for applications where the drive must operate steadily, with reasonable operating losses and reserve for demanding technological cycles. In practice, this means lower thermal load, a more favorable energy balance and a better foundation for economical operation of large technological units.
IE4 efficiency delivers lower losses for high-power drives
In large process equipment, IE4 Super Premium efficiency translates into lower energy losses and better utilization of supplied electrical energy throughout the working day. This three-phase electric motor is therefore suitable where the motor operates for long hours in steady-state mode or with alternating loads, but without room for unnecessary downtime. In the field of HV electric motors, this approach is particularly important for drives that form the basis of a production line or auxiliary power technology.
Welded steel frame simplifies handling at high output
The welded steel frame gives the structure high rigidity while also assisting with transport and installation of large assemblies, which is a practical advantage in heavy industry. Steel construction is suitable wherever demanding loads, vibration and precise positioning in a technological assembly are expected. From the perspective of integration into a machine room, this four-pole electric motor is ready for installation on robust foundations with emphasis on long-term service continuity.
Rated current of 222,7 A, power factor of 0,9 and efficiency of 96 % show that the motor is suitable for efficient power transmission in the 6000 V voltage class. Rated speed of 1491 rpm and rated torque of 12810 Nm emphasize its use in drives where a stable mechanical connection to technological equipment is required. Rotor inertia of 68,0 kg·m² and load inertia of 980,0 kg·m² are important when designing starting, braking and sizing of coupling and protection components.
Technical design supports reliable starting and protection
When designing the power supply and starting system, it is necessary to account for starting torque reaching 0,8 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 6 times the rated current. Such values are important when selecting the starting system, protection, cable routes and when assessing torque reserve on the shaft and in the technological machine. In industrial assemblies with higher inertia, correctly designed protection helps maintain safe starting and repeated operating modes without undesirable stress on the winding.
Standard thermal protection and monitoring improve operational supervision
The motor can be used in assemblies requiring continuous monitoring of winding and bearing temperatures as well as protection against condensation during shutdowns. Such a solution supports operation in a mode where motor condition must be monitored and deviations in load or cooling addressed promptly. Combined with suitable operating monitoring, it helps reduce the risk of unplanned downtime and extends the service life of the entire drive.
Use in processes with high torque demands
This H27R 5004-4-6 is suitable for applications where high availability, stable output and a design prepared for long-term operating load are required. Typical applications include:
- Main pumps in power-generation units.
- High-pressure fan units in thermal power plants.
- Compressor stations for process gases.
- Metering and transport conveyors in metallurgy.
- Mills and crushers in the raw-material industry.
- Rotary dryers in chemical production.
- Large mixing and homogenization units in cement plants.
The combination of rated output of 2000 kW, high torque and a design for demanding environments creates the prerequisites for long-term use in technologies requiring precise operational continuity. For operators of large factories, it is also important that the solution from VYBO Electric is based on many years of manufacturing experience in large drives and allows real data for power supply, cooling and maintenance to be used during project design.
