The H27R 5002-8-6 design provides higher operating efficiency and lower life-cycle costs for large drives. This 700 rpm electric motor with an output of 1000 kW is intended for applications where stable operation, starting reserve and reliable performance under long-term load are decisive. With the H27R-HD-Modular series, VYBO Electric combines robustness with a solution suitable for intensive industrial use.
Welded steel frame increases rigidity and facilitates installation
The H27R-HD-Modular series uses a welded steel frame that provides high strength at a lower weight than comparable cast-iron solutions. Such construction simplifies transport, movement within the installation hall and placement into technological units where precise geometry and reliable motor mounting are required. For large factories, this is a practical benefit both when planning shutdowns and when integrating into new lines.
The closed cooling system with an IC611 heat exchanger keeps the inside of the motor separated from ambient air, improving suitability for dusty or corrosive environments. In practice, this means more stable thermal conditions and lower stress on active components during long operating cycles.
Drive parameters support reliable distribution-system sizing
Rated current of 118,7 A, power factor of 0,85 and efficiency of 95,7 % help design power supply, protection and related compensation in the industrial network more precisely. Rated torque of 12836 Nm and rated speed of 744 rpm create an operating point suitable for heavy drives where stability and smooth power transmission are important. The eight-pole concept also naturally fits applications with a higher requirement for pulling force at lower speed.
Torque reserve is also important when designing starting and protection. Starting torque reaches 0,9 times the rated torque, breakdown torque 2 times the rated torque and starting current 5,3 times the rated current, providing a basis for correct configuration of starting components, protection devices and coordination with the mechanical load.
Rotor cage made of copper strip extends service life under load
The rotor cage made of copper strip helps reduce electrical losses and improves thermal resistance under repeated loads. In demanding manufacturing, this feature is particularly important where long operation without frequent intervention and stable parameters throughout the season or production cycle are expected. Combined with a stator winding impregnated using VPI technology, it creates a solution suitable for a high degree of operational reliability.
Insulation class F together with temperature rise class B provides reserve for continuous operation under conditions with higher thermal load. Package weight of 5280 kg requires well-planned logistics but also confirms the robust nature of the machine for large technological units.
HV electric motors for demanding industrial lines
In the category of HV electric motors, H27R 5002-8-6 is used where high availability, precise sizing and compatibility with extensive operating units are required. As a high-voltage electric motor, it is suitable for environments requiring resistance to long-term load and stable operation with minimal unplanned downtime. For OEM integrators, predictability of mechanical and electrical interfaces with the other system components is also important.
Typical industrial applications
The design and output parameters make this motor suitable for a wide range of heavy technologies.
