H17RL 400X2-4 brings compact output to drives where every square decimetre of installation space matters, along with long-term energy efficiency. This electric motor from VYBO Electric is prepared for demanding drive technology in operations requiring stable running, precise reserve capacity for starting and reliable operation over long production cycles. In the 1400 rpm electric motor category, it is a solution that can maintain the required output without unnecessarily increasing installation-space requirements.
The design with a solid aluminium rotor cage supports smooth transfer of energy into the mechanical system and also helps during repeated starts, which are common in industry. The system is designed as an asynchronous electric motor for applications where not only output but also drive behaviour under changing load is monitored. Operators of large factories and OEM manufacturers of large technological systems appreciate that the motor can fit into existing projects without unnecessary compromise in equipment planning.
1400 rpm electric motor for smooth operation of production technologies
Rated speed of 1488 rpm provides a suitable basis for production lines where process continuity and load control over time are important. Rated torque of 4043 Nm provides reserve for starting heavier units, conveyors and pump assemblies operating continuously. A Tst/Tn starting torque ratio of 120 % and a Tmax/Tn breakdown torque ratio of 220 % help in applications requiring reliable starting and reserve for short-term operating peaks. This makes it easier to design the drive around the actual load of the technology and the predictable behaviour of the system.
In practice, this asynchronous electric motor can be used, for example, in the following applications:
- mills for grinding cement clinker in a cement plant
- fan units for flue-gas extraction in an incineration plant
- blowers for high-temperature technological lines in metallurgy
- pumps for process-water circulation in chemical production
- compressor assemblies for compressed air in large production halls
- aggregate crushers in a quarry with continuous operation
- extrusion lines in plastics production
- rotary drum mixers for heavy material mixtures
- raw-material transport conveyors in port terminals
Robust cast-iron construction for long-term industrial loading
Robust cast-iron construction increases mechanical resistance to vibration, load fluctuations and long service intervals. This property is particularly important where the motor is installed in a system with a high mass of rotating parts and where stability during continuous operation is expected. The weight of 3510 kg reflects a concept designed for rigid mounting in an industrial frame and reliable operation in environments where performance is judged by technology availability, not marketing.
Insulation class F combined with temperature rise B supports operating reserve during longer duty cycles. DE bearing 6326C3 and NDE bearing 6326C3 are selected so that the motor can handle demanding operation with an emphasis on bearing service life and precise rotor guidance. This makes the asynchronous electric motor suitable for environments where servicing is planned during shutdowns and every unnecessary intervention in the line is monitored.
Choice of voltage for projects with different network architectures
The option to choose the voltage makes integration easier in projects using different network standards and distribution configurations. For integrators and OEM manufacturers, it is important that the motor can be adapted to operation at 440 V, 500 V, 690 V or 720 V according to the technology design. This shortens solution-approval time and reduces the number of interventions in the electrical installation during implementation.
Rated current of 1076 A at △ 400V and 624 A at Y 690V provides relevant input for sizing supply and protective components. A power factor of 0,88 and efficiency of 96,3 % support rational use of electrical energy in operations with long running times. Combined with external starting inertia of 413,000 kg·m² and a GD² moment of inertia of 37,200 kg·m², the motor can also be integrated into robust drive assemblies where an accurate balance of the complete system is required. In practice, this means the drive technology remains under control both during design and subsequent operation.
VYBO Electric supplies this model backed by ISO certificates, which is important in industrial projects for quality audits and repeated deliveries into standardised assemblies. The H17RL 400X2-4 therefore combines compact output, a stable mechanical concept and broad use in demanding technological systems. For large factories and OEM projects, it is ready as a solution that fits production lines, energy nodes and auxiliary drives without unnecessarily extending installation time.
