H17RL-450X2-4 is a three-phase electric motor with an output of 900 kW that supports energy efficiency and stable operation in industrial practice even under long-term load. Thanks to its design for a 400/690 V network and rated speed of 1490 rpm, this 1500 rpm electric motor is suitable where operations need high power density without unnecessarily increasing the space required by the technology.
1500 rpm electric motor for compact output in large operations
Compact output is particularly important when designing drives in press shops, conveyor nodes and technological systems where every metre of installation space matters. This asynchronous electric motor with a squirrel-cage rotor delivers torque of 5768 Nm while allowing consistent operation in high-load applications. For OEM manufacturers and operators of large factories, this means easier integration into existing frames, fewer changes to the layout and more precise sizing of the complete drive system.
Robust cast-iron construction for demanding industrial use
Robust cast-iron construction increases mechanical resistance and helps maintain stability even in environments with increased vibration, thermal stress and long duty cycles. With a weight of 5200 kg, the motor has the characteristics needed for smooth operation in production lines requiring precision and resistance to sudden changes in load. In practice, this is particularly appreciated by operations requiring long service life without frequent shutdowns and unnecessary maintenance interventions.
Advanced lubrication and maintenance during continuous operation
Advanced lubrication and maintenance are designed in this model so that the bearings can handle long production cycles with minimal restrictions. The motor is equipped with bearing relubrication during operation, which simplifies service planning and helps extend the service life of key components. DE 6328C3 and NDE 6328C3 bearings together with copper bars in the rotor cage support reliable starting even during repeated starts common in large technological assemblies. Within the VYBO Electric portfolio, this solution draws on years of experience supplying industries with high availability requirements.
Typical use in demanding technological systems
This asynchronous electric motor with a squirrel-cage rotor is particularly suitable for the following applications:
- Main crusher drive in stone-processing and mining lines.
- Pumping stations for process-water circulation.
- Ventilation units for large filtration and extraction systems.
- Conveyor routes in metallurgical and materials production.
- Raw-material processing mills in the cement industry.
- Extruders and mixing units in chemical production.
- Compressor systems in energy and industrial operations.
VYBO Electric for operations that need dependable performance
VYBO Electric supplies solutions for large factories and OEM integrators who need a motor prepared for real operating conditions, not just catalogue comparisons. This model combines rated current of 1533 A at △ 400 V, 891 A at Y 690 V, efficiency of 96,3 % and a power factor of 0,88, helping with the design of switchboards, starting systems and downstream protection. Insulation class F and temperature rise B support stability in long-term use where smooth operation without compromises in the technology is expected.
For operations dealing with high loads, starting ratios of 110 % and 220 % together with a starting current of 750 % provide a basis for safe integration into heavy-duty applications. The 1500 rpm electric motor in the H17RL Compact PRO design is ready for use where high power density, reliability and a service concept suited to industrial reality are expected from the drive.
