Copper rotor for long service life gives model H17R-315-F-2-6 compact output that pays off in continuous operation. This 2900 rpm electric motor with an output of 315 kW is designed for lines where starting stability, thermal resistance and long service intervals are decisive. In practice, this means less downtime and more reliable operation under loads that are already beyond the limits of ordinary drives.
2900 rpm electric motor for 6 kV industrial drives
The design meets the requirements of large factories and OEM manufacturers of technological systems that need a reliable three-phase electric motor for 6 kV industrial drives. The high-voltage electric motor with a rated current of 35,6 A and rated torque of 1010 Nm provides reserve for pumps, compressors and mixers where smooth operation and precisely predictable behaviour under changing load are important.
The copper rotor alloy limits losses and tolerates temperature better in environments where the motor is exposed to long-term operation. A power factor of 0,9 together with efficiency of 95,1 % helps keep operating costs under control, which is already noticeable in large drives running continuously. For integrators, the IEC frame size of 315 mm is also important because it makes designing the base, transmissions and connection to existing technology easier.
IE4 efficiency for long production cycles
IE4 Super Premium efficiency is evident where the motor runs at high utilisation throughout the year. In such applications, it is important that every unnecessary watt is converted into heat rather than useful output. This three-phase electric motor is therefore suitable for production technologies that need long cycles, limited downtime and precise planning of energy consumption.
With this series, VYBO Electric builds on years of experience in large drives, which is reflected in both the design and the operating details. Accessories for monitoring and protection are also available, helping with integration into motor supervision and with thermal stability. In practice, this makes deployment easier in applications where fast diagnostics and reliable monitoring of the bearings and winding are required.
Protection for demanding environments in continuous production
Special protection for demanding environments is beneficial in operations with dust, moisture or process washing. Available IP56, IP65, IP66 and IP67 solutions give designers room to select the level of protection according to the specific application. Combined with a weight of 3040 kg and rotor moment of inertia of 3,100 kg·m², this creates an assembly that maintains stable operation even with high technological inertia.
Design that maintains operating conditions even under higher load
Insulation class F and temperature rise B provide reserve for long operating intervals, while 6317-C3 bearings on both the DE and NDE sides support stable running in demanding conditions. A starting ratio of 0,7 % and breakdown ratio of 3,2 % are important when designing technology that needs precisely controlled acceleration and safe behaviour across the entire operating range. For operators of large factories, this is a practical basis for maintenance planning and for sizing the entire drive.
The 2900 rpm electric motor from this series is suitable for raw-water pumps, high-pressure pumps, centrifugal compressors, combustion-line fans, chemical-reactor mixers, rolling tables, heavily loaded conveyor belts, aggregate crushers, plastics extruders and separation centrifuges. VYBO Electric supplies a solution that simplifies the design of large drives and helps keep production moving at the required pace, so take advantage of the offer for your project today.

2900 rpm electric motor for design without unnecessary compromises
When larger technologies are designed, allowance is made for the reserve the motor can provide during load peaks as well as long-term operation. This model is therefore suitable for operations where energy balance, service availability and drive precision are monitored as one complete system. H17R-315-F-2-6 offers a balance of output, efficiency and durability, which is decisive for industrial design.
If you need a motor for a new line or a replacement for an existing drive, this high-voltage electric motor from VYBO Electric provides a practical basis for reliable operation. Thanks to its well-considered design and the option to adapt protection to the environment, it is easier to integrate into production systems where every day of operation matters.
Precise deployment in heavy industrial practice
Model H17R-315-F-2-6 is suitable for solutions where long-term drive stability, easier maintenance and predictable behaviour under changing technological load are expected. Combined with careful installation design and temperature monitoring, it can support the production regime without unnecessary intervention. For OEM projects, it is also important that the motor fits into the design of large systems without unnecessary structural modifications.
