The H27R 5604-4-6 electric motor with an output of 3150 kW for a 6000 V power supply is designed to help reduce operating costs in large process units while maintaining stable output even under prolonged loads. This three-phase electric motor with a rated speed of 1494 rpm belongs to the 1400 – 1500 rpm class, so it fits well into drives requiring consistent speed and high operational reliability.
Cost savings in long-term operation of high-power lines
High efficiency of 96,4 % and a power factor of 0,91 improve the drive’s energy balance in environments where every loss is reflected in electricity bills and cooling requirements. Rated current of 345,5 A, rated torque of 20136 Nm and robust construction provide reserve for continuous use in heavy industry.
The design with a welded steel frame provides high rigidity with dimensions suitable for large drives while facilitating handling during transport and installation. The closed IC611 air-to-air cooling system keeps the internal environment of the motor separated from surrounding dust and aggressive fumes, increasing suitability for operations with demanding environmental conditions.
Design prepared for high torque demands
Torque characteristics are also important for the design of starting and protection systems. Starting torque reaches 0,9 times the rated torque, breakdown torque 2,6 times the rated torque and starting current 7 times the rated current, allowing correct sizing of starting equipment, power supply and protection relays in networks with high installed power. As a high-voltage electric motor, this model is suitable where a firm torque reserve and reliable coordination with converters, starters or direct-on-line power supply are expected.
Rotor cage and bearing arrangement for long service life
The rotor with a cage made of copper strip helps reduce electrical losses and handles thermal stress during repeated peaks well. DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 support stable mounting with the substantial rotor inertia of 93,0 kg·m² and load inertia of 1080,0 kg·m², which is particularly important during large starting and coast-down cycles.
Use in power generation, mining and raw-material processing
This 4-pole electric motor is suitable for a wide range of large applications where reliability, a long interval between shutdowns and the ability to operate under stable load are decisive. In practice, it is used for raw-material mills, furnace fans, process-air compressors, cooling-circuit pumps, mixers for chemical plants, crushers, high-torque conveyors, briquetting presses, rolling lines, desulfurization units, blowers, elevator conveyors, mixing drums, ore-processing equipment, as well as main drives in cement plants and paper mills. In these segments, precise motor sizing helps limit unplanned downtime and support stable production.
Technical prerequisites for operation in demanding environments
Insulation class F together with temperature rise B provides a favorable foundation for long-term winding durability under industrial load. Package weight of 8560 kg confirms the massive design intended for large technologies where a solid foundation, precise installation and long-term operation without unnecessary servicing are expected.
What the technical drive design focuses on
When designing the drive, we recommend monitoring not only output and voltage but also system inertia, load characteristics and required overload protection. The H27R 5604-4-6 is therefore suitable for projects involving an energy-efficient large drive with emphasis on reliable starting, stable operation and long component life. If you are planning modernization or replacement of a main drive, take advantage of the offer and obtain a solution that supports higher technology availability and lower operating costs.
Output for large industrial units with a long service interval
The combination of high efficiency, a robust frame, effective cooling and a well-designed rotor makes this model a suitable choice for high-voltage industrial drives. With correctly designed downstream components, the motor helps maintain the production rhythm, reduce the risk of failures and ensure efficient utilization of installed output throughout the equipment’s life cycle.
