High-voltage electric motor 1600 kW, 994 rpm, 6 000 V, H17R 560-A-6-6

Energy efficiency is decisive in large drives, and the H17R 560-A-6-6 model with an output of 1600 kW is designed to maintain it even in continuous operations. This high-voltage electric motor from VYBO Electric operates as a 1000 rpm electric motor in applications requiring stable running, high operational reliability and reasonable demands on energy distribution throughout the plant.

IE4 efficiency in high-load operations

The IE4 Super Premium class is intended for drives that run for long hours and significantly affect the consumption of the entire technology. In such applications, differences in power loss translate into the cost of every shift, so this 6000 V electric motor is particularly relevant in heavy industry, the energy sector and large manufacturing units. In practice, it is a solution that helps maintain efficiency at a level suitable for large process lines while keeping operation technically predictable.

Industrial companies also value the fact that a six-pole electric motor with a rated speed of 994 rpm provides a suitable basis for applications with smoother running and lower mechanical stress on downstream equipment. Such behaviour is important during starts under load as well as prolonged loading, where not only output but also the behaviour of the entire drive in the actual line is monitored.

Compact 6 kV motor for space-constrained assemblies

The design with a shaft height of 560 mm makes it possible to integrate this compact 6 kV motor into assemblies where available space must be used without sacrificing output. For projects based on standardized frames, it is important that drive technology of this type can deliver full output within H315 to H560 frames while simplifying the design of both new and modernized assemblies.

The frequency selection option is also important because the equipment can be prepared for 60 Hz operation. This is practical for export projects, international manufacturing standards and technologies where the operating environment changes according to the local grid. As a result, the motor adapts more easily to different production locations without unnecessary intervention in the drive concept.

Stable torque during demanding starts

Rated torque of 15372 Nm and rated current of 183,6 A give designers room to engineer a drive for equipment with high inertia and long start-up times. A low starting torque ratio and favourable breakdown torque ratio assist in applications where motor behaviour during starting, load changes and short-term process deviations is monitored.

Industrial operation also requires resistance to thermal and mechanical influences, which makes insulation class F together with temperature rise B important. Such a design supports long winding service life in environments where the motor experiences repeated load cycles, high operating temperatures and limited opportunities for shutdown.

Monitoring motor condition in continuous operation

Condition monitoring is essential for large drives, which is why 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and a 3xPTC thermistor can be used. Such equipment supports monitoring of temperature conditions during starting, steady operation and shutdown, reducing the risk of unplanned intervention in production.

A weight of 8300 kg and rotor moment of inertia of 97,0 kg·m² are values that must be considered when designing foundations, handling and connection to the machine set. A rotor cage made of copper strip contributes to stable energy transmission in demanding operating modes where long service life and consistent drive behaviour are expected.

Precise use for heavy industry

This model is suitable for applications where output without unnecessary compromises in drive design is required. Typical uses include exhaust fans in metallurgical operations, blowers for process furnaces, compressor assemblies in refineries, ore-processing mills, crushers in quarries, agitators in chemical reactors, pumps for power-plant cooling circuits, heavy conveyor lines in mining, drum dryers, rolling stands, drives for desulphurization units, raw-water pumping stations, aerators in wastewater treatment plants and winding equipment for paper machines.

For operators of large factories, it is essential that the design of this motor class takes into account long-term loading, planned servicing and the impact on overall energy balances. For these machines, VYBO Electric states ISO certifications as part of the manufacturing and inspection framework, which is important during audits and when standardizing procurement of replacement equipment.

If you need a solution for process or power drives, order H17R 560-A-6-6 in good time and minimize the risk of delay when starting the project.

A 1000 rpm electric motor in this class is prepared for long-term operation where every kilowatt-hour and every percentage point of line availability counts.
