H17RL 400X2-2 delivers compact output for continuous energy-efficient operation
In demanding operations, it matters whether the drive can handle high loads without taking up unnecessary extra space. The H17RL 400X2-2 from VYBO Electric is designed to provide compact output within industrial drive technology, allowing sensible integration into existing production lines, pumping stations and technological systems. This asynchronous electric motor with an output of 630 kW and a high operating speed of 2980 rpm supports energy efficiency in long-term use while still leaving room for service access and installation clearances.
Operators of large factories especially appreciate that a 2900 rpm electric motor can respond to production requirements in practice without unnecessary downtime. In this type of application, not only output is monitored but also the ability to maintain stable operation during repeated starts and changing torque. That is why this asynchronous electric motor is suitable where high process reliability, precise drive sizing and a long operating interval between maintenance interventions are required.
2900 rpm electric motor for high-load processes
The rated torque of 2019 Nm provides the necessary reserve for both starting and steady operation in production technologies subject to shock loads. A starting torque ratio of 120 % and a breakdown torque ratio of 200 % help in applications where the drive is expected to overcome machine resistance smoothly during starting and short-term overloads. A starting current ratio of 750 % requires corresponding electrical sizing, which is a standard part of project preparation in OEM designs and larger installations.
With an efficiency of 96,1 % and a power factor of 0,89, this electric motor is suitable for operations that monitor energy consumption and network stability. Insulation class F together with temperature rise B support reliable operation even under long-term load, which is important in metallurgical, process and conveyor technologies. In practice, the asynchronous electric motor therefore behaves predictably, making it easier to design switchboards, motor protection and coordination with frequency-controlled or direct starting systems.
Robust cast-iron construction maintains stability in heavy-duty operation
Robust cast-iron construction is especially important in a drive of this output because it helps damp vibrations and maintain precise motor geometry during long-term use. In environments requiring high mechanical resistance, stability and long service life, this construction provides a less sensitive response to frame loading, better resistance to installation stresses and greater reliability during continuous operation. With this solution, VYBO Electric also addresses manufacturers of technological systems who need a dependable foundation for heavy equipment.
The solid aluminium rotor cage supports even transfer of energy to the load and helps during repeated starts in applications where the drive must withstand demanding duty cycles. DE bearing 6220C3 and NDE bearing 6220C3 are selected for stable industrial operation and are well suited to machines with long operating hours. This is another reason why this asynchronous electric motor with a squirrel-cage rotor is suitable for projects where high technology availability is expected.
Voltage selection makes integration into existing distribution systems easier
The option to choose the voltage simplifies deployment in plants using different network standards or export machine configurations. Available 440 V, 500 V, 690 V and 720 V versions make it easier to adapt the drive to the specific electrical infrastructure without unnecessary changes to the overall equipment concept. For OEM manufacturers, this is a practical advantage in series production because one motor type can be used in multiple machine versions.
A weight of 3500 kg and external starting inertia of 206,000 kg·m² indicate that this solution is intended for robust assemblies with high dynamic loads. A GD² moment of inertia of 19,600 kg·m² helps when designing starting characteristics and coordinating the motor with gearboxes, couplings or direct drives. This enables good integration into production systems where output, mechanical durability and service accessibility need to be combined within one unit. In this context, ISO certificates represent standard evidence of controlled manufacturing and inspection processes.
Practical use in heavy industry and OEM assemblies
H17RL 400X2-2 is used in technological systems where continuous operation and precisely designed drives are a priority. Typical applications include:
- Main pump units in chemical plants.
- Conveyor belts in mining operations.
- Ventilation units for large industrial halls.
- Compressor stations in processing plants.
- Raw-material mills in cement plants.
- Extruders for polymerisation and plastics-processing lines.
- Stone crushers in quarries and stone-processing operations.
- Rotary drum mixers in heavy engineering.
For operators of large factories and OEM partners alike, it is important that the drive can be integrated into existing technology without disproportionate modifications and with consideration for the service regime. In practice, this means better shutdown planning, easier replacement during repowering and greater certainty in projects designed for long-term operation. The 2900 rpm electric motor in this configuration supports technologies that need a combination of output, stability and reasonable space requirements. Order it in good time so you have a solution ready for the next production season.
