H27R 4001-6-6 is a 900 rpm electric motor designed for applications where stable output, long service life and reasonable operating costs are decisive. This high-voltage electric motor with an output of 450 kW, voltage of 6000 V and rated speed of 992 rpm delivers efficiency of 94,7 % and a power factor of 0,86, helping reduce energy losses in continuous operation. VYBO Electric offers it as a solution for modern drive technology where reliable operation and control of total costs are important.
Welded steel frame simplifies handling of large units
The H27R-HD-Modular series uses a welded steel frame that combines high rigidity with a more favorable weight compared with conventional cast iron. This facilitates transport, placement and alignment within the technological unit while supporting precise installation in production lines. For operators of large factories, this is a practical benefit both when replacing machines and when integrating them into new projects.
Closed IC611 cooling increases durability in demanding environments
H27R-HD-Modular motors are equipped with IC611 air-to-air cooling, which maintains a clean internal circuit and improves suitability for dusty or corrosive environments. The closed concept helps protect active motor components from contaminants and stabilizes thermal conditions under long-term load. In industrial operations with higher requirements for ambient air cleanliness, this is a significant advantage while maintaining reliability.
Copper rotor cage supports efficient energy transfer
The rotor cage made of copper strip reduces electrical losses and helps maintain thermal resistance during repeated operating cycles. Combined with the stator winding impregnated using VPI technology, it contributes to stable output even under prolonged load. For a three-phase electric motor in demanding industrial use, this is an important basis for long service life and consistent parameters.
Parameters for reliable starting and drive protection
Rated current of 53,4 A, rated torque of 4332 Nm, starting torque at 1 times the rated torque, breakdown torque at 2,3 times the rated torque and starting current at 5,9 times the rated current give designers a basis for power-supply, protection and mechanical-reserve design. Such data are appreciated by OEM manufacturers of large technological units as well as service teams that need predictable behavior during starting. The design uses insulation class F, temperature rise class B, 6326-C3 bearings on both the DE and NDE sides, rotor inertia of 19,6 kg·m² and load inertia of 663,0 kg·m².
