High-voltage electric motor 1800 kW, 744 rpm, 6000 V, IC611, H27R 5603-8-6

In heavy process operations, the energy balance of the entire drive is decisive, especially during continuous operation of mills, compressors, pumps and conveyor lines. H27R 5603-8-6 is designed as a high-power 750 rpm electric motor with an output of 1800 kW that provides stable torque and favorable operating efficiency in the large-drive category. For the operator, this means lower losses during long production cycles and better control over electricity consumption.

The H27R-HD-Modular series uses a closed IC611 cooling circuit that keeps the motor’s internal air separated from the surrounding environment and increases suitability for dusty or corrosive conditions. Combined with IE4 Super Premium efficiency, this reduces energy losses under high load and makes the motor a better fit for modern industrial high-voltage drives. VYBO Electric also uses VPI impregnation of the stator winding in this series, increasing resistance to moisture, vibration and long-term stress.

Efficient operating foundation for large technological units

This high-voltage electric motor is intended for applications where reliable operation with a 6000 V supply, a precise relationship between torque and speed, and long-term thermal reserve are decisive. Rated current of 212,5 A, a power factor of 0,85 and efficiency of 96,2 % provide a technical framework for operation with emphasis on economy. Insulation class F together with temperature rise class B supports stable thermal resistance under continuous load.

• Rated torque of 23105 Nm provides reserve for starting and steady-state load of large technological units.

• Starting torque reaches 0,7 times the rated torque, breakdown torque 1,8 times the rated torque and starting current 4,7 times the rated current, which is important when designing starting, protection and power-supply components.

• Rotor inertia of 191,0 kg·m² and load inertia of 3980,0 kg·m² help assess the dynamics of the entire drive in heavy-duty operation.

• Package weight of 8000 kg reflects robust construction suitable for large machine units and service handling in an industrial environment.

Use in industry where operational reliability is important

H27R-HD-Modular is used in rotary and linear technologies where long service life must be combined with efficient cooling and precise torque characteristics. Large material-processing units, heavy auxiliary drives and power units operating under high load throughout the day are typical for this 8-pole electric motor. Rated speed of 744 rpm naturally corresponds to applications where lower speed at high torque is desirable.

Design elements for long drive life

DE bearing arrangement NU238-C3+6040-C3 and NDE NU230-C3 support reliable shaft guidance under high load and during long operating cycles. The combination of a robust frame, precisely defined thermal class and closed cooling keeps the motor ready for continuous work in technological units where shutdowns are costly. With correctly designed starting and power-supply sizing, the motor becomes a stable core of the drive with high operational availability.
