H17RL 400X1-6 is a three-phase motor designed for operations where energy efficiency directly translates into more stable costs and lower drive loading. As a 6-pole electric motor, it operates at 990 rpm and provides reserve capacity appreciated by large factories and OEM manufacturers of technological systems.
6-pole electric motor for stable operation of production technologies
In heavier-duty applications, the main consideration is how the motor handles long-term load, repeated starts and process changes. A three-phase electric motor in this configuration provides smooth starting and appropriate torque for mixing lines, conveyors and pump assemblies.
Thanks to a shaft height of 400 mm, the motor is easier to integrate into large assemblies without unnecessary modifications to the machine frame. Customers in practice also appreciate that it is a low-voltage electric motor suitable for standard industrial 400/690 V power supplies.
Robust cast-iron construction for long service life
Robust cast-iron construction is essential at this output because it helps maintain mechanical resistance, mounting stability and accuracy during continuous operation. This is especially important where vibration, dust and temperature changes are part of daily operation.
Robust cast-iron construction also contributes to the motor maintaining its behaviour over long service intervals. For the production line, this means fewer unplanned shutdowns and easier maintenance planning.
Compact output for demanding industrial use
Compact output means that the motor can provide exceptional performance in a compact frame without unnecessarily complicating the machine-room layout. This is an advantage when designing equipment where every millimetre of installation space matters.
The H17RL 400X1-6 model can be used, for example, in cement mills, aggregate crushers, rolling lines, plastics extruders, compressor stations, large fans, vacuum pumps, chemical-mixture mixers, mining conveyors, rotary drum dryers, cooling-circuit pumps, sorting-line drives, food-industry mixers and recycling-sorting drives. In these applications, the drive’s energy efficiency is fully demonstrated.
Choice of frequency for project solutions
For international projects, it is practical that the motor is also available for 60 Hz, simplifying deployment in equipment for export markets or technological systems with a different network configuration. Proven manufacturer and distributor VYBO Electric also helps keep deliveries aligned with production planning.
6326C3 bearing arrangement on both the DE and NDE sides supports reliable operation under long-term load. From a drive-design perspective, the GD² moment of inertia of 50,000 kg·m² and external starting inertia of 443,000 kg·m² are also important, giving designers a better basis for selecting starting modes.
Performance data that helps with drive sizing
Industrial operations need a reliable link between design and actual load. That is why operating values such as rated current △ 400V 788 A, rated current Y 690V 457 A, rated torque 4341 Nm and ratios Tst/Tn 120 %, Tmax/Tn 200 % and Ist/In 680 % are also important for the H17RL 400X1-6 model.
Efficiency of 96,1 % and a power factor of 0,86 support sensible operation over long shifts. Insulation class F, temperature rise B and a weight of 3650 kg complete the profile of a motor prepared for long-term use in demanding technological assemblies.
If you need a motor for a production line that cannot be stopped, order the H17RL 400X1-6 as soon as possible. Availability can change quickly in projects, and ordering in good time helps keep the installation schedule on track without unnecessary delays.
