The H27R-HD-Modular series design is prepared for high loads where stable operation, low losses and long-term output availability are decisive. The H27R 5002-6-6 model with an output of 1250 kW is intended for drives requiring high operating reserve and precisely controlled power supply on 6000 V networks. In practice, it is a 1000 rpm electric motor that naturally fits demanding operations with emphasis on energy efficiency and reliable torque transmission.
IC611 air-to-air cooling reduces the risk of fouling and overheating
The H27R-HD-Modular series uses a closed cooling circuit with a heat exchanger that helps keep the inside of the motor separated from the surrounding environment. IC611 air-to-air cooling supports cleanliness of the internal airflow, which is practical in dusty halls, metallurgy and corrosive environments. With this solution, thermal stability is better maintained even under prolonged load.
IE4 efficiency supports continuous operation
IE4 Super Premium efficiency helps limit energy losses in large drives and increases the economy of the entire operating cycle. Combined with VPI impregnation of the stator winding, resistance to moisture, dust and vibration increases, which is beneficial for a high-voltage electric motor in continuous industrial operation. This combination of solutions is suitable where efficiency, service life and simpler maintenance are monitored.
Torque reserve and starting conditions for heavy drives
H27R 5002-6-6 is a 6-pole electric motor with rated current of 145,2 A, rated torque of 12010 Nm and a power factor of 0,87. Starting torque reaches 1,1 times the rated torque, breakdown torque 2,3 times the rated torque and starting current 6,6 times the rated current, which is important when designing starting, protection and power-supply sizing.
Parameters suitable for large process and power drives
For designers and operators in drive technology, data supporting precise assessment of system load and dynamics are also important. This motor has a rated speed of 994 rpm, efficiency of 95,5 %, insulation class class F and temperature rise class class B. Rotor inertia reaches 70,0 kg·m² and load inertia 1620,0 kg·m², which is useful when designing starting and controlling torque peaks.
Bearings and mechanical durability for long service intervals
The NU238-C3+6040-C3 bearing arrangement on the DE side and NU230-C3 on the NDE side supports stability under higher axial and radial loads. Package weight of 5440 kg corresponds to robust construction intended for heavy industry, large pumps, compressors, fans and technological lines with continuous operation.
Industrial use and fast ordering
The H27R 5002-6-6 model is used in flue-gas desulfurization, main mine ventilation systems, blast-furnace blowers, cement mills, ore mixers, bulk-material conveyors, extrusion lines, compressor stations, large centrifugal pumps, cooling towers, machine press shops, heavy crushers, winches, drying drums, paper winders and turbo-fan drives. VYBO Electric supplies a solution that combines economical operation with durability for continuous load, so order it in time to shorten the preparation time of your technology for commissioning.
