The design of the H27R 5003-4-6 is intended for operations where a large drive is expected to provide high output of 1800 kW, stable behavior under long-term load and reasonable operating costs. This 1500 rpm electric motor operates at a rated speed of 1491 rpm and a supply voltage of 6000 V, so it is naturally suited to segments where reliable transfer of energy to the technology and low losses during continuous production are decisive.
Energy savings for large drives
Efficiency of 96,2 % and a power factor of 0,9 support more economical operation in systems that run at high utilization throughout the day. In practice, this means lower energy losses, better use of the power-supply infrastructure and more accurate sizing of switchboards and compensation. For large process and power drives, it is therefore important that the motor can transmit 11529 Nm of rated torque without unnecessary overheating and with reserve for stable production load.
- Output of 1800 kW supports use in heavy continuous-duty operation.
- Rated current of 200,7 A helps with power-supply and protection design.
- Rated torque of 11529 Nm is suitable for demanding technological units.
- Starting torque reaches 0,8 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 6 times the rated current, which is important when designing starting and protection systems.
Cooling and insulation for demanding environments
The closed cooling circuit with IC611 air-to-air cooling keeps the inside of the motor separated from the surroundings, helping in dusty or corrosive environments. Combined with IE4 Super Premium efficiency, thermal losses are reduced and the motor maintains its operating temperature better during long operation. VPI impregnation of the stator winding further increases resistance to moisture, dust and vibration, which is important for equipment with high mechanical and electrical loads.
- Insulation class F supports safe operation under higher thermal load.
- Temperature rise B helps keep operating conditions within a reasonable range.
- Rotor inertia of 61,0 kg·m² and load inertia of 883,0 kg·m² are important when designing starting and switching logic.
- Package weight of 5850 kg requires advance planning of handling and installation.
Typical high-load industrial applications
In practice, this solution is used as a high-voltage electric motor for compressor drives in refinery and petrochemical lines, for large cooling-water pumps in the power industry, for fans in furnace and filtration systems, for crushers and mills in cement plants, for raw-material conveyors in mining, and for mixing and process units in metallurgical production. In such applications, the motor’s ability to carry long-term load, respond to torque changes and maintain stable thermal conditions is decisive.
This 4-pole electric motor is suitable where the operator needs a reliable basis for large high-voltage industrial drives while also aiming to limit unplanned production interventions. The DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 are selected with regard to high mechanical load and long-term operation in heavy industry. The H27R series design is therefore suitable for both modernization projects and new projects in which the drive is expected to have a long service life and predictable behavior.
A solution for projects where operational reliability is decisive
VYBO Electric supplies a configuration that helps align output, cooling and electrical parameters with the requirements of large technology. If you are planning a replacement or a new project, order the motor in advance so that during installation you have room to check starting, power supply and installation interfaces without unnecessary waiting.
