Electric motor 1800 kW, 1494 rpm, 6000 V, H17R-500-D-4-6 MV

When selecting a drive for medium-voltage technology, it is worth starting with the load, operating mode and required efficiency, because these are the factors that determine the stability of the entire line. The H17R-500-D-4-6 model with an output of 1800 kW and a speed range of 1400-1500 rpm is designed to support efficient operation of a medium-voltage drive in segments with demanding requirements for availability, thermal reserve and long-term reliability. As a medium-voltage asynchronous electric motor, it provides a solution that is suitable for integration into technologies with demanding starting as well as steady load.

Why the 1400-1500 rpm speed class is suitable for stable industrial operation

The rated speed of 1494 rpm places the motor precisely in an operating condition where smooth power transfer and predictable behaviour under load are required. The rated torque of 11506 Nm supports robust starts and duty cycles with higher inertia, while the Ist/In value of 6,8 % helps in the design of the power supply and switching infrastructure. The power factor of 0,91 and efficiency of 96,8 % reduce energy losses in long operating periods, which is especially important in the energy sector and heavy industry.

The design with a 500 mm frame size is suitable for machines where it is necessary to align mechanical interfaces, space requirements and cooling. Insulation class F together with temperature rise B provides a reserve for thermally demanding modes, while the weight of 7330 kg and rotor inertia of 39,0 kg·m² support robust mechanical behaviour under load. The copper bar rotor cage improves rotor conductivity and helps maintain consistent operating characteristics during repeated starts.

Technical equipment increases operational safety and makes integration easier

For OEM manufacturers and drive system integrators, readiness for monitoring and protection is also important. The motor is equipped with 6x PT100 in the winding, PT100 in both the DE and NDE bearing, anti-condensation heating and 3x PTC, which makes it easier to supervise the temperature condition and supports long-term operational reliability. The DE bearing and NDE bearing are available on request, so the final configuration can be adapted to the specific technology. In practice, this will be appreciated by operations that work with their own maintenance standard and internal diagnostic requirements.

Use in industrial technologies with demanding requirements

An electric motor for universal industrial applications in this power range is used where reliable continuity and precise drive sizing are required. In the portfolio of LV electric motors from VYBO Electric, this motor is particularly suitable in the following areas:

• Pumping stations for energy and water management.
• Ventilation and blower units in large technological complexes.
• Compressor units with high operating load.
• Drives for mills, crushers and mixing equipment.
• Production lines for processing raw materials in heavy industry.
• Designs requiring high efficiency and a long service interval.
• Integrated drive systems in OEM equipment.
• Technologies requiring individual adaptation according to the environment and enclosure.

A solution for long-term reliability and service confidence

VYBO Electric is one of the most significant companies in its sector in Central Europe and relies on its own research and development as well as technical consulting in drive design. The H17R-500-D-4-6 model combines 1800 kW output, rated speed of 1494 rpm, 6000 V supply and a robust construction for industrial use, where long-term stability, efficiency and adaptability are decisive.
