In heavy production, power generation and continuous process lines, every kilowatt-hour matters. H27R 5602-2-6 is a solution for operations that need a 2900 rpm electric motor with an output of 2500 kW, stable torque and long-term economy. In practice, it delivers lower operating losses, a better consumption balance and reserve for large technological systems.
This three-phase electric motor belongs among robust HV electric motors intended for high-power applications where precise operation and high availability are expected. The design with a welded steel frame increases assembly rigidity, improves handling during installation and keeps structural weight under control at high outputs. Efficiency of 97 % together with a power factor of 0,92 helps optimise the power supply and reduce thermal loading of both the grid and drive.
Higher energy return during continuous operation
Under long-term loading, it is essential for the motor to operate economically without unnecessary losses in the copper and iron circuits. IE4 Super Premium efficiency in this design supports production economics especially where the drive runs many hours per day and energy consumption translates into the total line costs. Rated current of 269,6 A and rated speed of 2988 rpm enable power-supply and protection design with an emphasis on process stability.
Starting parameters for protection and torque-reserve design
When starting a large drive, it is necessary to account for starting torque reaching 0,52 times the rated torque, breakdown torque 2,5 times the rated torque and starting current 5,9 times the rated current. These data are important when designing the starting system, selecting protective components and assessing torque reserve for starting the technological system. Rated torque of 7990 Nm provides a precise basis for the mechanical connection to the process equipment.
- Rated output of 2500 kW is suitable for large continuous drives with high demand for utilisation of installed input power.
- A 560 mm frame size supports integration into robust production systems and power frames.
- Insulation class F and temperature rise B help maintain thermal reserve during long operating cycles.
- Rotor inertia of 41,0 kg·m² and load inertia of 156,0 kg·m² are important when assessing the dynamics of starting and stopping the system.
Deployment in high-load applications
The H27R 5602-2-6 motor design is suitable for high-flow pumping stations, compressor units in the chemical industry, fan systems for power-generation units, crushers in raw-material processing, mixing and homogenisation units in cement plants and belt conveyors for mining and material transport. In each of these applications, stable operating speed, resistance to long-term loading and precise adaptation of the drive to the technology are important.
Temperature monitoring and winding protection during long operation
Standard thermal protection and monitoring increase operating safety in environments where the motor often runs continuously. The use of PT100 sensors in the winding and bearings, PTC thermistors and 230 V anti-condensation heating improves drive-condition supervision and limits the risk of unplanned shutdowns. From a maintenance perspective, this provides a practical foundation for reliable diagnostics and service-interval planning.
- The motor is suitable for high-voltage industrial distribution systems and central energy management in operations with high consumption.
- A package weight of 6900 kg must be considered in logistics, installation and foundation-frame preparation.
- DE bearing available on request and NDE bearing available on request allow the final design to be coordinated with project requirements.
Precise technical integration into large drives
During design, it is important to coordinate the electric motor with the gearbox, coupling, protective components and load characteristics. The H27R 5602-2-6 model, with a rated output of 2500 kW and efficiency of 97 %, provides the conditions for efficient operation in applications where high availability and controlled energy costs are expected. Thanks to the VYBO Electric design, this 2-pole electric motor is prepared for technologies requiring a robust, long-term stable solution.
