Electric motor 560 kW, 1485 rpm, 400/690 V, H17RL 355X4-4

H17RL 355X4-4 from VYBO Electric is designed for drive technology where the motor is expected to provide compact output in limited installation space while maintaining stable operation under high load. With an output of 560 kW and a rated speed of 1485 rpm, this 1400 rpm electric motor is suitable where the drive must maintain production continuity without unnecessary changes to the machine design. For operators of large factories and OEM manufacturers of technological systems, the ability to transfer power into the process without disproportionately increasing the frame size and without complications during integration into existing assemblies is particularly important.

1400 rpm electric motor for continuous output in ongoing operations

Rated torque of 3601 Nm gives the drive reserve capacity during starting and short-term load changes. In practice, this means the three-phase electric motor handles transport and process tasks with a lower risk of speed drop at critical moments in production. Customers dealing with long duty cycles particularly appreciate that the motor maintains its operating mode even with variable demand and does not burden the technological system with unwanted fluctuations.

• Pressing and forming lines requiring high torque.
• Main drives of belt conveyors in heavy industry.
• Raw-material processing mills with long-term loads.
• Pump units for process water and cooling circuits.
• Ventilation and extraction systems in large production halls.
• Extruder assemblies in polymer processing.
• Reduction gear drives for continuous mixing equipment.
• Rolling lines in metallurgical operations.
• Crushers and sorters in aggregate processing.

Robust cast-iron construction for mechanical durability in heavy-duty operation

The cast-iron motor body supports assembly rigidity and helps maintain precise positioning in applications exposed to vibration, shock loading and long-term thermal stress. This robust cast-iron construction is particularly important in installations running continuously where every service intervention translates into downtime costs. The design is therefore suitable for an asynchronous electric motor with a squirrel-cage rotor that must withstand demanding starting conditions in an industrial environment while maintaining operating stability.

Combined with insulation class F and temperature rise B, the operation gains a motor prepared for long working intervals under sensibly controlled thermal load. Efficiency of 96,3 % and a power factor of 0,87 provide energy departments and drive designers with a practical basis for power-supply design and distribution sizing. Reduced heat losses can also reduce the need for intervention in the machine’s cooling concept.

Voltage selection for OEM integration and trouble-free connection

The ability to adapt the voltage makes this solution a flexible component for equipment manufacturers supplying technologies to different countries and network conditions. Available variants of 440 V, 500 V, 690 V and 720 V simplify deployment in projects requiring compatibility with local infrastructure and existing plant distribution systems. For OEM production, this approach is important because it shortens engineering time and reduces the risk of modifications during machine commissioning.

Rated currents of 968 A at △ 400V and 561 A at Y 690V give designers a basis for designing starting, protection and the supply path. A starting torque ratio of 120 %, breakdown torque ratio of 200 % and starting current ratio of 700 % help when selecting transmissions, couplings and protective components in the assembly. These values are useful when planning technological systems where the electrical and mechanical parts must work as one unit.

ISO certificates and operating reliability for long production cycles

Industrial purchasing departments and technical managers monitor not only output parameters but also manufacturing stability and process traceability. ISO certificates within the VYBO Electric portfolio are therefore an important factor when assessing series deliveries and standardising drives across plants. A weight of 3000 kg, external starting inertia of 367,000 kg·m² and a GD² moment of inertia of 34,000 kg·m² confirm that this is a robust machine for applications with higher dynamic requirements.

DE bearing 6322C3 and NDE bearing 6222C3 support long-term operation in assemblies where precise mechanical connection and reliable running under continuous load are expected. The solid aluminium rotor cage is suitable for operations requiring reliable starting and repeatable drive behaviour in time-intensive cycles. For large factories and OEM designers, this means fewer design compromises and greater confidence when deploying the motor in series applications.

If you need a 1400 rpm electric motor for a production line, pumping station or technological system, H17RL 355X4-4 provides compact output that simplifies machine integration and supports long-term operating stability. Take advantage of the offer from VYBO Electric and choose a solution that fits your drive technology better without unnecessary design modifications.
