Energy efficiency is decisive for large drives, especially where a 1000 rpm electric motor is used in continuous operation and every power draw is reflected in costs. The H17R 400-B-6-6 model with an output of 450 kW is designed for factories where operation must remain stable, losses reasonable and long production cycles dependable.
IE4 Super Premium efficiency helps keep consumption under control even under demanding load. In practice, this is valuable in applications such as compressor stations, process-water pumps, bulk-material conveyors, mills for raw-material processing, agitators in production lines, fan systems and extruders in plastics processing. Such use requires a high-voltage electric motor that can withstand long-term loading without unnecessary downtime.
1000 rpm electric motor for demanding drives with lower losses
In this power class, the mechanical arrangement of the drive is also important. The compact 6000 V electric motor uses space efficiently, making it easier to integrate into the machine frame as well as an existing technological assembly. For OEM manufacturers of large units, this means fewer compromises when designing power distribution, enclosures and service access.
Compact 6-pole electric motor in a 400 mm frame
A shaft height of 400 mm helps keep dimensional requirements under control even where full output is expected in limited space. The design is suitable for integration into assemblies where precise connection to gearboxes, couplings and process control is important. Copper strip in the rotor cage supports durability during starting and stability throughout repeated operating cycles.
- Rated torque of 4350 Nm supports smooth acceleration of heavy technological units.
- Rated current of 53,5 A simplifies sizing of the power supply and protective elements.
- A power factor of 0,85 helps utilize energy transmission more effectively in industrial power distribution.
- 6326-C3 bearings on both the DE and NDE sides are suitable for stable operation under demanding conditions.
Advanced temperature monitoring for long operation without surprises
Operators of large factories often need more than the drive simply running. Advanced temperature monitoring through PT100 sensors in the winding and bearings simplifies supervision of machine condition and helps detect deviations early, before a shutdown occurs. It is complemented by an anti-condensation heater, which supports equipment readiness after downtime and during fluctuations in ambient temperature.
Reliability during starts, loading and long production cycles
Industrial technologies also benefit from insulation class F, temperature rise B and efficiency of 95,7 %, as these properties help maintain stable output under prolonged loading. A rotor moment of inertia of 12,5 kg·m² supports a balanced starting profile, and rated torque of 4350 Nm gives the drive reserve capacity for process peaks.
- A starting current ratio of 6,1 % assists in the design of starting and protection.
- A breakdown torque ratio of 2,3 % supports use in processes with variable load.
- A starting torque ratio of 1,1 % is suitable for controlled starting of technological units.
- A weight of 4110 kg reflects the robustness of the solution for stationary industrial applications.
As a proven manufacturer and distributor, VYBO Electric supplies solutions that fit the real requirements of large operations and OEM projects. If you need a drive for a technological unit with an emphasis on efficiency, stability and motor-condition monitoring, order this model without unnecessary delay.
