The design of H17R-400-D-4-6 is intended for operations where energy efficiency, stable running and long-term availability of spare parts are expected from an electric motor. This 1500 rpm electric motor operates with an output of 710 kW and is ready for use in technological units where not only output, but also disciplined power consumption and operational reliability are monitored. VYBO Electric operates as the largest company in its sector in Central Europe, which in practice translates into technical support and experience with large industrial drives.
IE4 Super Premium efficiency for energy-efficient operation
IE4 Super Premium efficiency is suitable wherever the combined effect of heat losses, consumption and time in continuous operation matters. In drives of this size, high efficiency has a direct impact on energy costs as well as on the thermal stress of the entire drive system. For large factories and OEM manufacturers, this means more predictable cooling design and lower loading of downstream components.
Compact 6 kV motor for large technological units
This 6000 V electric motor fits the output into a 400 mm frame so that it remains suitable for technological units with limited space. The compact 6 kV motor is attractive for projects that use higher voltage while also requiring a reasonable footprint and easier integration into an existing machine room. Within the H17R Compact PRO-HV series, full output can therefore be maintained without unnecessarily enlarging the drive assembly.
Voltage selection for different power supply systems
The option to select the voltage makes use easier in new projects as well as when replacing older drives. In practice, this helps with coordination with the grid and with switchgear specifications, where values of 3 300 V, 6 000 V, 10 000 V or 11 000 V are often used. For integrators, this is an advantage when standardizing solutions across multiple production lines.
HV electric motors for continuous industrial use
HV electric motors in this output range are used in operations where stable load and precise behaviour during long operating cycles are required. As a high-voltage electric motor, H17R-400-D-4-6 offers a rated current of 79,4 A, rated torque of 4551 Nm, power factor of 0,9 and rated speed of 1490 rpm, providing a suitable basis for designing a drive with controlled starting. A 4-pole electric motor in this category fits well into pump, compressor and crushing applications.
Temperature monitoring and winding protection during long shifts
Temperature monitoring is also important for demanding operations. Available sensing in the winding and bearings, together with an anti-condensation heater, helps keep the motor ready to start after a shutdown and reduce risks when conditions in the machine room fluctuate. Such a solution is practical in lines where repeated starts and accurate recording of drive condition are expected.
Design for heavy-duty operation and dependable servicing
A weight of 4250 kg, rotor moment of inertia of 9,8 kg·m², insulation class F, temperature rise B and a rotor cage made of copper strip create the basis for stable operation in demanding conditions. 6326-C3 bearings on both the DE and NDE sides are suitable for applications where service life during long running periods and higher mechanical loads is monitored. In practice, this is appreciated by operators of mixers, mills, centrifuges, fans, blowers, compressors, pumps, conveyors, rolling tables, granulators, extruders, crushers and heat-exchanger units.
Solution for large factories and OEM projects
When designing large technological units, it also matters how quickly the drive can be incorporated into the project and how consistently it will behave in series production. This 1500 rpm electric motor is suitable for integrators who need to maintain the same standard across multiple machines, minimize intervention in the mechanical section and keep the energy balance of the entire line under control. Order H17R-400-D-4-6 in good time to obtain a solution prepared for planned shutdowns as well as deployment without unnecessary delays.
