In crushing, pumping, mixing and material-transport lines, the stability of the entire system is determined mainly by how the drive behaves under continuous load. H17RL 355X3-6 is designed for energy efficiency in operations where high power density and reliable operation without unnecessary downtime are expected. This 1000 rpm electric motor from VYBO Electric draws on years of manufacturing experience and the requirements of large factories and OEM assemblies.
1000 rpm electric motor for continuous load in industrial production
Rated speed of 990 rpm helps maintain smooth operation in drives where stable torque transfer and predictable starting behaviour are monitored. The asynchronous electric motor in this design is suitable for equipment operating in long production cycles and requiring reserve capacity for both starting and operating peaks.
Combined with an output of 400 kW and rated torque of 3859 Nm, this creates a solution capable of handling demanding processes without excessive space requirements in the machine room. Compact output is particularly evident where a higher power class must be fitted into a limited installation area.
Compact output for large technologies with limited space
The 355 mm frame size supports installation in robust assemblies where not only output but also sensible use of available space is important. Robust cast-iron construction provides higher mechanical resistance and stability under vibrations common in heavy industrial operation.
Efficiency of 96,1 % and a power factor of 0,85 help reduce operating losses during long-term use. An electric motor of this class is therefore suitable for technologies where costs are monitored over the entire drive life cycle, not only at purchase.
Robust cast-iron construction for vibration, dust and long duty cycles
Insulation class F together with temperature rise B supports operation in modes where the motor is exposed to higher thermal loads. The solid aluminium rotor cage helps transfer energy during starting and at repeated operating points.
A weight of 2800 kg and a GD² moment of inertia of 47,200 kg·m² provide a basis for stable operation in large technological systems. External starting inertia of 394,000 kg·m² corresponds to applications where the motor is connected to a significant mechanical load.
Advanced lubrication and maintenance for long service intervals
Bearing relubrication during operation reduces the need for intervention during normal production and simplifies maintenance planning. DE bearing 6322C3 and NDE bearing 6222C3 are selected to support longer service life in applications where high drive availability is expected.
Rated current △ 400V 709 A and rated current Y 690V 411 A are important when designing switchboards, soft starters and protective components in OEM projects. A starting current ratio of 650 % and breakdown torque ratio of 200 % give designers room to size the starting system appropriately.
Applications for production lines, material transport and technological systems
This electric motor is used in demanding operations where stable running and a predictable service strategy are important.
- Cement-clinker mills in raw-material and final processing.
- Aggregate crushers in quarrying and processing lines.
- Process-water pumping stations with long continuous operation.
- Fan units for dust extraction in metallurgical halls.
- Belt conveyors with high torque load during starting.
- Mixing units for chemical and construction mixtures.
- Extrusion and granulation lines in plastics processing.
VYBO Electric for OEM projects and large industrial applications
Operators of large factories and OEM manufacturers of technological systems especially appreciate when a motor is ready for integration into a wider system without lengthy design compromises. In this case, convincing performance is combined with an installation concept required by modern production lines and heavy process technology.
VYBO Electric has long worked with solutions for segments where spare-parts availability, service planning and parameter stability over time are decisive. For orders tied to projects with a short schedule, it is advisable to order the motor in good time to maintain a smooth installation and commissioning process.
H17RL 355X3-6 is ready for use where reliability, energy efficiency and compact output are expected from the drive. If the goal is to keep the technology running without unnecessary downtime, order it for your project as soon as possible.
