The 2900 rpm electric motor in the H17R Compact PRO-HV class delivers compact output for lines that cannot afford unnecessary downtime. Model H17R-400-C-2-6 with an output of 630 kW is designed for 6 kV industrial drives where smooth starting, stable operation and long-term durability in continuous service are expected from the motor. In practice, users particularly appreciate that it is a high-voltage electric motor with parameters suitable for large technologies, pumps, fans and compressors. VYBO Electric uses years of experience from heavy-duty projects, which is reflected in a design adapted to real operating loads.
2900 rpm electric motor for drives that need stable pulling force
The copper rotor is key to longer service life because the copper rotor alloy helps maintain low losses and handles thermal stress under continuous load more effectively. For the operator, this means lower energy losses and more reliable reserve during repeated starts. The three-phase electric motor in this version builds on a proven concept that performs well on lines with high operating-hour loads. IE4 Super Premium efficiency supports cost reduction where every kilowatt-hour enters the long-term economic calculation. The design with a 400 mm frame size gives the project a solid basis for integration into robust units.
Protection and operational monitoring in demanding conditions
Special protection for demanding environments helps maintain operation where dust, moisture or frequent temperature changes must be addressed. With available IP56, IP65, IP66 and IP67 protection ratings, the integrator can select a solution according to the conditions of the specific technology. The three-phase electric motor with insulation class F and temperature rise B is prepared for long operating cycles, while 6319-C3 bearings on both the DE and NDE sides support precise rotor mounting. Diagnostics are also important for technological systems, so the availability of 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistors simplifies machine-condition monitoring.
Stability for OEM and large technological systems
OEM manufacturers particularly appreciate that the 2900 rpm electric motor can be designed into systems with precisely defined dynamic behaviour. Rated torque of 2019 Nm and rated current of 69,7 A give designers a basis for sizing the drive branch. Rotor moment of inertia of 4,900 kg·m² helps when designing acceleration and coordinating it with control. A weight of 3820 kg also indicates a robust design suitable for industrial assemblies with high requirements for rigidity and stability.
Design prepared for a long service interval
In large factories, the service strategy matters as well as the start itself. This is why a solution combining efficiency, thermal reserve and a suitable bearing configuration is practical. The high-voltage electric motor within H17R Compact PRO-HV operates with a power factor of 0,91, which helps both when designing the supply and assessing the actual network load. A rated speed of 2980 rpm is suitable for applications where rapid and uniform energy transfer into the process is important. This makes the motor well suited to central technologies that must remain in operation even with a higher number of starts.
Specific uses in industrial practice
In operation, this model can be used, for example, for:
- driving the main process pump in a chemical plant,
- a combustion-air system fan in the energy sector,
- a compressed-air compressor in a metallurgical line,
- an extraction fan in a cement plant,
- a raw-material processing mill in heavy industry,
- an extruder in a polymer production line,
- a mixer for process tanks in pharmaceutical production,
- a heavily loaded conveyor in a logistics hub,
- a pumping station for a water-management facility.
H17R Compact PRO-HV for reliable operation of production technologies
Model H17R-400-C-2-6 combines an output of 630 kW with a design intended for a long operating horizon. A copper rotor, IE4 Super Premium efficiency and available protection for demanding environments form a foundation that makes design, maintenance and economic evaluation easier for OEM manufacturers and operators of large factories alike. If you need a solution for demanding industrial drives, take advantage of the offer and choose a motor that will support the reliability of the entire technology.
