High-voltage electric motor 2800 kW, 2989 rpm, 6000 V, IC611, H27R 5603-2-6

H27R 5603-2-6 provides a 2900 rpm electric motor for operations that need high output, stable speed and lower costs over a long life cycle. This high-voltage electric motor with an output of 2800 kW and a voltage of 6000 V is designed for heavy-duty deployment in power generation, manufacturing and process technologies where reliable operation at a rated speed of 2989 rpm and efficiency of 97,1 % are decisive.

The design is based on a welded steel frame that combines high rigidity with easier handling during transport and installation of large machines. The closed IC611 air-to-air cooling system helps keep the motor interior clean, which is practical in dusty or corrosive environments. For the operator, this means more stable conditions for drive technology and better motor readiness for long-term loading.

Starting and operating relationships are also important for drive design. Rated current of 301,6 A, a power factor of 0,92 and rated torque of 8946 Nm provide a solid basis for sizing the power supply and protection. During starting, it is advisable to account for starting torque reaching 0,59 times the rated torque, breakdown torque 2,6 times the rated torque and starting current 6,4 times the rated current. In practice, this supports more precise selection of the switchboard, switching equipment and overcurrent protection for large industrial units.

Power and efficiency support lower operating costs

In continuous industrial deployment, not only output but also how much energy the motor converts into useful work is decisive. Efficiency of 97,1 % helps limit losses during long operating cycles, which is important for highly utilised drives. Insulation class F in combination with temperature rise B increases reserve for stable operation under demanding thermal loading. This three-phase electric motor is therefore suitable wherever long-term and repeatable loading without compromising operating confidence is expected.

Rotor inertia of 45,0 kg·m² and load inertia of 180,0 kg·m² are important when designing starting, braking and the dynamics of the complete line. They allow more precise assessment of system behaviour with large fans, pumps, crushers or rolling technologies. With this type of solution, VYBO Electric focuses on operating reliability, service predictability and longer intervals between interventions.

Typical deployment in heavy industry

The H27R 5603-2-6 two-pole electric motor is intended for applications requiring high output and consistent operation at high speed. Thanks to its robust design, it is suitable for both modernisations and new installations in large plants where connection to gearboxes, couplings or directly to the technological machine is expected.
