Compact output for demanding drives
H17RL 400X2-6 is a high-power-density solution for operations where space, torque and stable energy transfer are decisive. This 1000 rpm electric motor is designed for integration into large technological systems where precise connection to gearboxes, pump systems and process lines is expected without unnecessary design compromises.
With an output of 500 kW and a frame size of 400 mm, this low-voltage electric motor provides a space-efficient solution for applications with high operating loads. In practice, this means lower installation-space requirements, easier integration into existing assemblies and better coordination with the drive train.
1000 rpm electric motor for continuous industrial operation
Rated torque of 4823 Nm supports smooth starting and stable operation even under demanding starting conditions. A starting torque ratio of 120 % and breakdown torque ratio of 200 % give designers scope to create a drive that can handle dynamic load changes without excessive stress on mechanical components.
Rated current of 876 A at △ 400V and 508 A at Y 690V is important when sizing switchboards, protective components and cable routes. A power factor of 0,86 and efficiency of 96,1 % help keep operation within a sensible energy balance, which affects long-term costs in continuous shifts. Insulation class F together with temperature rise B supports reliable operation over longer duty cycles.
Robust cast-iron construction for stability and long service life
The cast-iron design gives the motor the rigidity needed under vibration, shock loading and repeated starts. In heavy-duty technologies, this property is decisive because it reduces the risk of unwanted deformation and supports precise motor positioning within the assembly. A weight of 3750 kg also contributes to overall stability in operations working with high output and continuous load.
The solid aluminium rotor cage is designed to withstand demanding duty in industrial applications with frequent starts and load changes. 6326C3 bearings on both the DE and NDE sides complete the assembly with robust support suitable for long-term operation in engineering, energy and process systems.
Advanced lubrication and service readiness
The motor is equipped with bearing relubrication during operation, which significantly simplifies maintenance planning in factories where shutdowns are tracked down to the minute. In practice, this means better service continuity, a lower risk of premature wear and easier coordination between maintenance and production. This also makes the low-voltage electric motor suitable for operations with a high proportion of continuous production.
Years of experience at VYBO Electric are reflected in a design that takes into account the needs of OEM manufacturers of large technological systems and factory operators with a high degree of automation. Predictable drive behaviour under real operating conditions is especially important, where not only output but also the service cycle and compatibility with downstream equipment are assessed.
Use in highly loaded technological systems
This electric motor is used in equipment where a combination of torque, stability and long operating periods without excessive downtime is required. It is suitable for various industrial applications requiring reliable power transfer to rotating technological nodes.
- Main mills in cement production lines.
- Slurry pumps in mining ore processing.
- Compressors in petrochemical operations.
- Aggregate crushers in quarrying lines.
- Fan units for combustion technologies.
- Extruders in plastics processing.
- Mixer drives in chemical reactors.
- Rolling stands in metallurgical production.
- Conveyor-system drives in warehouses with continuous operation.
Sizing for a 400/690 V network and industrial control
When designing the power supply, compatibility with 400/690 V network parameters and the expected drive load in the specific technology is important. External starting inertia of 492,000 kg·m² and a GD² moment of inertia of 53,200 kg·m² help designers assess starting, run-down and the dynamics of the complete assembly more accurately.
