Long description
When a production plant needs a stable drive with high torque and no unnecessary downtime, the correctly sized motor in the correct speed class makes the difference. The H17R-315-F-4-6 model with an output of 315 kW is designed for operation in the 1400-1500 rpm range, where it delivers balanced running under demanding load and helps maintain production continuity even during long-term deployment. In the VYBO Electric portfolio, it is a solution for companies looking for greater reliability in production operations without compromises in integration into existing infrastructure.
This H17R-315-F-4-6 operates with a supply of 6000 V and achieves a rated torque of 2028 Nm at a rated speed of 1483 rpm. Thanks to the rated current of 36.3 A, power factor of 0.88 and efficiency of 95.2%, it is suitable where not only performance but also operating economy is being monitored. Temperature rise B combined with insulation class F supports a safe thermal regime under longer loading and reduces the risk of unwanted overheating in industrial cycles.
Speed class 1400-1500 rpm for stable pull in demanding duty
In the drive segment with rated speed of 1483 rpm, this medium-voltage asynchronous electric motor stands out where operation must be smooth, response predictable and performance resistant to load changes. The rotor inertia of 6.3 kg·m² contributes to balanced starting as well as stability during steady running. The copper bar rotor cage supports efficient energy transfer to the shaft and is suitable for applications with frequent requirements for long-term load.
- Rated current of 36.3 A makes it easier to size the supply and protection devices.
- Rated torque of 2028 Nm provides a reserve for heavier process loads.
- Ist/In 5.9% helps control starting in high-power networks.
- Tst/Tn 0.95% supports a firm starting when the system is accelerated.
- Tmax/Tn 2.4% brings a short-term mechanical reserve under peak load.
Construction that supports long service life in continuous operation
When modernising drives, the rated output is often not the only consideration, as mechanical durability, service accessibility and the motor’s ability to operate in long production cycles are also important. This electric motor for universal industrial applications uses 6322-C3 bearings on both the DE and NDE sides, which supports robust rotor mounting under industrial load. A weight of 3120 kg and dimensions tied to the 315 mm frame create a design suitable for technologies where rigidity and precise alignment with the connected equipment are important.
Temperature monitoring and protection for sensitive technological units
The equipment includes thermal protection with 6x PT100 in the winding, PT100 in the DE and NDE bearings, anti-condensation heating and 3x PTC. Such a solution gives operations a better overview of the motor condition and helps detect unusual thermal conditions in time before a shutdown occurs. For technology suppliers and production plants, this is a practical basis for integration into monitoring systems and service plans.
Connection to medium-voltage networks without complications in drive design
The H17R-315-F-4-6 model is suitable for companies working with a voltage level of 6000 V and needing to connect a new drive reliably to existing infrastructure. Depending on the project, the motor can also be matched to other voltage levels, which simplifies modernisation in plants with varying technical standards. The result is a lower risk of incompatibility when replacing older units and faster commissioning of the technology.
- Frame size of 315 mm, that is the centre height, makes it easier to design a replacement for existing motors.
- Adaptation for 3.3 kV, 6 kV, 10 kV and 11 kV networks expands the range of industrial applications.
- Bearings on both the DE and NDE sides with type 6322-C3 support stability during long running.
- The copper bar version in the rotor cage is a benefit in demanding power transmission.
Industrial applications in heavy-duty operation and drive modernisation
- Pump sets in chemical and power generation production.
- Fan units for extraction and air circulation.
- Stack and process blowers in large-scale technologies.
- Compressor systems with high continuous load.
- Mills and crushers in raw material processing.
- Conveyor belts in heavy industry and logistics.
- Rolling and handling drives in metallurgy.
- Mixing equipment for the chemical industry.
- Extruders with requirements for stable torque.
- Granulation lines and bulk material processes.
- Technological lines for cement plants.
- Mine conveyors and auxiliary drives.
- Water management and large pumping stations.
- Power blocks with industrial control.
- Reconstruction of older medium-voltage drives.
