The H27R 4002-2-6 motor is designed for operations that require high output, long service life and lower operating costs without unnecessary downtime. This 2900 rpm electric motor with an output of 630 kW and a 6000 V power supply is suitable for lines where load stability, efficiency and reliable integration into large technological systems are decisive. Thanks to high efficiency of 96,2 % and a power factor of 0,9, it helps reduce energy losses and supports the energy efficiency of the complete drive.
The substantial welded steel frame provides high rigidity at a favourable structural weight, simplifying transport and installation of large machines. Closed IC611 air-to-air cooling keeps the motor interior cleaner and improves suitability for dusty or corrosive operating environments. Copper rotor bars reduce electrical losses and help maintain thermal resistance under long-term loading. This three-phase electric motor from VYBO Electric is intended for environments where every operating cycle must deliver predictable results.
Power and torque reserve for heavily loaded production lines
Rated torque reaches 2016 Nm, providing sufficient reserve for technological systems with fluctuating resistance and frequent load changes. Start-up data also help when designing the power supply and protection: starting torque reaches 0,8 times the rated torque, breakdown torque 2,6 times the rated torque and starting current 6,6 times the rated current. Rated current of 70,3 A and insulation class F provide a solid basis for long-term operation in high-power industrial assemblies.
Mechanical durability for demanding operating conditions
The design with a 400 mm frame size and package weight of 2780 kg is prepared for robust installation in a machine block where precise positioning and vibration resistance are required. Rotor inertia of 7,3 kg·m² and load inertia of 60,0 kg·m² support the design of couplings, transmissions and starting procedures in applications with higher dynamic loading. 6319-C3 bearings on both the DE and NDE sides are selected for reliable operation in demanding service.
Typical deployment in large operations
- Main drive for rolling lines in metallurgy.
- Compressor systems in large power-generation units.
- Pumps for process and cooling water.
- Fans for boiler rooms and dust-removal systems.
- Crushers in mineral processing.
- Mills in cement and lime production lines.
- Extruders in chemical polymer processing.
