In heavy industrial operation, what matters is whether the drive can keep the production line moving without unnecessary downtime. Model H17R-315-E-2-6 with an output of 280 kW delivers high power density for applications where the 2900 rpm electric motor must operate steadily even under higher loads and at a supply voltage of 6 000 V.
Compact 6000 V electric motor for space-constrained assemblies
The 6000 V electric motor in a compact design helps simplify the design of switchboards, foundations and service access. In practice, OEM manufacturers of large technological systems appreciate this where full output must fit within a package that does not complicate installation in existing technologies. This is also why this three-phase electric motor is suitable for drives with requirements for energy efficiency and long-term operation without frequent interventions.
- Slurry and process pumps with high flow resistance.
- Fans for main technological systems in production halls.
- Compressors in the energy sector and gas processing.
- Crushers in cement plants and stone-processing operations.
- Rolling and conveyor lines in metallurgy.
- Mills and mixing units in the chemical and processing industries.
2-pole electric motor with speed for a smooth process
The 2-pole electric motor with a rated speed of 2976 rpm is suitable where the process requires brisk acceleration, precise connection to power stages and consistent operation under load. Rated torque of 899 Nm supports operating modes in which both impact and long-term forces are transferred to the drive without loss of stability.
Copper rotor for long service life under continuous load
Copper strip in the rotor cage reduces losses and improves thermal resistance, which is reflected in long production cycles as well as repeated starts. Low operating losses are also supported by efficiency of 95 % and a power factor of 0,9, allowing the drive to use electrical energy more effectively under demanding network conditions.
Temperature monitoring for safe motor operation
Advanced temperature monitoring via PT100 sensors in the winding and bearings helps operators respond before a small deviation becomes a shutdown. With a weight of 2950 kg and rotor inertia of 2,700 kg·m², this is a solution that maintains operating discipline even in technological systems with longer starting times and higher requirements for bearing protection.
Service foundation for operators and OEM projects
As a proven manufacturer and distributor, VYBO Electric supplies a solution that fits the practice of large-factory operators as well as OEM integrator projects. Insulation class F, temperature rise B, 6317-C3 bearings on both the DE and NDE sides and available accessories including 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistors provide the basis for reliable integration into long-term operations.
Deployment in environments with higher availability requirements
The motor is prepared for technological systems where not only output is monitored, but also process stability, thermal control and service predictability. Thanks to these properties, it performs well in projects where the drive is expected to support continuous production without unnecessarily increasing operating costs.
