High-voltage electric motor 630 kW, 1489 rpm, 6 000 V, H17R-400-C-4-6

Compact output in model H17R-400-C-4-6 is combined with 630 kW of power and reserve for operations that need a reliable 1400 rpm electric motor without unnecessary downtime. This high-voltage electric motor is designed for deployment where smooth starting, stable engagement and long-term operation in harsh conditions are decisive. For operators of large factories and OEM manufacturers of technological systems alike, it is important that this is a VYBO Electric solution based on years of experience with high-voltage drives.

Copper rotor maintains operation during long-term deployment

The main design benefit is the copper strip in the rotor cage, which helps reduce losses while tolerating thermal load during repeated starting more effectively. In practice, this means less undesirable overheating, more stable operation and better resistance under an irregular load profile. 6 kV industrial drives therefore get a motor prepared for long production cycles as well as operating modes with higher torque requirements. Rated torque of 4041 Nm provides support when starting technological nodes where a consistent mechanical response is expected.

IE4 Super Premium efficiency reduces energy losses

IE4 Super Premium efficiency is important where the motor operates for dozens of hours each day and every kilowatt-hour contributes to operating costs. Efficiency of 95,9 % helps keep consumption under control, while a power factor of 0,89 supports sensible integration into the existing electrical installation. A three-phase electric motor with a rated current of 71,3 A and a rated speed of 1489 rpm is suitable for drives that require a predictable response without fluctuations in output.

The four-pole electric motor in this configuration is used in pumps, fans and operations where maintaining speed within a narrow band under long-term load is important. A starting-current ratio of 6,1 % and the torque ratios support the design of starting circuits and the power supply when integrating into larger assemblies. A weight of 4170 kg and rotor moment of inertia of 9,3 kg·m² are values that can be reliably considered during project design when selecting foundations, couplings and service access.

Special protection for demanding environments protects the drive core

For environments with dust, moisture or occasional wash-down, available IP56, IP65, IP66 and IP67 protection ratings are decisive and expand the possibilities for use on production lines and in auxiliary technologies. Insulation class F combined with temperature rise B supports long-term winding stability under cyclic load and reduces the risk of unplanned service intervention. DE bearing 6326-C3 and NDE bearing 6326-C3 are sized for demanding industrial operation where not only output but also service continuity is monitored.

• For main process-water pumps in energy and chemical production.
• For blowers on combustion and drying lines in large factories.
• For compressor assemblies in central machine rooms.
• For mixing units in plants producing cement and mineral mixtures.
• For conveyor systems with continuous or intermittent load.
• For crushing and grinding equipment in raw-material processing.
• For rolling and winding technologies in metalworking production.
• For turbo fans and extraction units in demanding operations.

Design prepared for integration into large assemblies

The 400 mm frame size makes installation design on existing foundations easier while leaving room for robust motor mounting in technological systems. Combined with rated torque and stable speed, this is a solution that simplifies both the design of new lines and modernisation of older drives. With this model, VYBO Electric addresses operations that need a proven platform for long-term operation and easier coordination of service interventions.

Additional sensors increase operational monitoring

In demanding applications, you will also appreciate enhanced temperature monitoring, which supports an early maintenance response to changes in load or cooling. Such a solution helps prevent unplanned shutdowns and improves planning of service intervals according to the actual condition of the equipment. For operations with high availability requirements, this is a practical way to keep the drive in a stable regime throughout the entire production campaign.
