In demanding pressing, pumping and conveyor assemblies, every loss and every shutdown matters. H17R 500-C-6-6 from VYBO Electric is designed for operations that expect energy efficiency, reliable reserve capacity and a long operating cycle from a high-voltage drive. At an output of 1250 kW, it helps reduce energy requirements under continuous load while maintaining stable operating behaviour, which is also valued from a 1000 rpm electric motor in large-factory applications.
IE4 efficiency for drives with long daily operating schedules
IE4 Super Premium efficiency is beneficial wherever the motor runs continuously and every kilowatt-hour is reflected in the plant budget. The design supports energy efficiency in heavy process drives, making it suitable for lines with high requirements for both smooth operation and control of operating costs. In this segment, a 6000 V electric motor is particularly useful when output must be combined with economical operation without unnecessary downtime.
Compact solution in a 500 mm frame
A 500 mm frame size helps with integration into technology where space is expensive and installation interventions must remain under control. The compact 6 kV motor can deliver full output in H315 to H560 frames, simplifying replacement of existing drives in distribution systems, compressors or mills. The option to monitor the condition of windings and bearings is also practical for maintenance because advanced temperature monitoring increases reliability during long production cycles.
Stability during starting and steady load
A rated speed of 995 rpm supports even power transmission in applications requiring precise process control and lower dynamic shocks. A rotor cage made of copper strip helps the 6-pole electric motor maintain consistent behaviour even during frequent load changes. Bearing and winding measurements are also prepared for long-term monitoring in environments where it is not economical to address overheating only after a fault occurs.
Monitoring that helps plan shutdowns
Advanced temperature monitoring is particularly useful in operations where peak loading alternates with long production windows. This model also offers 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistor, simplifying drive-condition monitoring in both converter-fed and direct-grid assemblies. Such a solution reduces pressure for unplanned intervention in metallurgy, chemical production, cement plants and mining technologies.
Use in heavy industry and the energy sector
H17R 500-C-6-6 is suitable for coke-plant blowers, raw-material conveyors, slurry pumps, mill drives, agitators in chemical production, traction fans, compressor stations, rolling-stand drives, ore crushers, furnace exhaust fans, dewatering pumps, cooling towers, paper-machine winders, agitators in wastewater treatment plants and heavy-duty mining belt lines. In these applications, predictable operation that supports the stability of the entire technology is decisive.
VYBO Electric as a proven partner for large drives
VYBO Electric is a proven manufacturer and distributor of drives for industrial applications where technical continuity, service experience and long-term solution availability are required. If you need a motor for modernization or a new line, order H17R 500-C-6-6 in good time to minimize time out of operation and maintain the planned deployment without unnecessary delay.
