H17R-450-A-4-6 is an electric drive unit with an output of 800 kW, prepared to maintain energy efficiency even in operations with high loads. In this category, a 1500 rpm electric motor is well suited wherever smooth starting, stable torque and long-term operation without unnecessary downtime are decisive. For operators of large factories as well as OEM integrators, the high-voltage electric motor represents a solution that takes into account the requirements for process continuity, service availability and sensible integration into larger technologies.
IE4 Super Premium efficiency for demanding industrial drives
IE4 Super Premium efficiency brings lower losses under load, which is reflected in operations where every watt saved affects the cost of the entire drive. 6 kV industrial drives in this version benefit from a design intended for long operating cycles and stable output under repeated loading. In practice, this means less heat in the system, lower cooling requirements and better planning of the energy balance of the entire line.
Compact 6000 V electric motor for space-demanding assemblies
A 6000 V electric motor with a shaft height of 450 mm makes it possible to use the output in a body that integrates well into large machine assemblies and technological blocks. The four-pole electric motor provides a suitable compromise between speed and torque, which is practical for pumps, compressors and conveyor sections with continuous load. Thanks to this concept, the motor is suitable wherever space, service access and ease of connection to existing infrastructure are decisive.
Special protection for operation in dusty, humid and aggressive environments
Several protection levels are available for demanding environments, helping to keep the drive operating even with increased humidity, dust or process fumes. Such a solution is valued by operations where the motor is located close to raw materials, washing zones or outdoor technological areas. VYBO Electric draws on many years of experience in design and supply for industrial use, so the construction takes into account real service conditions as well as requirements for integration into larger units.
Motor design for reliable long-term operation
Important operating parameters include a rated current of 89,4 A, rated speed of 1488 rpm, rated torque of 5134 Nm and a power factor of 0,9. The motor operates with an efficiency of 96,1 %, has insulation class F and temperature rise B, which supports stability during long operating intervals. A rotor cage made of copper strip, 6328-C3 bearings on both the DE and NDE sides, a rotor moment of inertia of 13,0 kg·m² and a weight of 5000 kg create a robust basis for demanding technological applications. Starting torque, breakdown torque and starting current provide information about the motor’s behaviour when starting heavy equipment and during dynamic load changes.
Use in technologies with continuous load
In practice, this model is used to drive large centrifugal pumps, process compressors, flue-gas extraction fans, furnace blowers, mixers in chemical production, granulators, crushers, mills, rolling lines, winding stations, belt conveyors, cleaning drums and water-treatment technologies. This 1500 rpm electric motor is also suitable for applications where the drive is expected to respond steadily to load changes throughout the entire shift. Thanks to the VYBO Electric design, the motor can be included in projects where precise coordination with variable-frequency control, plant service logic and long-term availability of spare parts are decisive.
If you are planning a drive upgrade or a new OEM project, order H17R-450-A-4-6 without unnecessary delay so that you have sufficient time for integration and commissioning.
