Electric motor 800 kW, 1488 rpm, 6000 V, H17R-450-A-4-6 MV

When selecting a drive for demanding operation, it is worth choosing a solution that can handle high load, stable efficiency and long-term availability of spare parts. H17R-450-A-4-6 with 6000 V supply and an output of 800 kW is designed to deliver power for demanding technologies in the speed range of 1400-1500 rpm, where balanced operation and precise matching to process requirements are important.

Balanced output in the 1400-1500 rpm speed class

Rated speed of 1488 rpm fits well into a segment where reliable operation without unnecessary fluctuations is expected. Rated current of 89.4 A, rated torque of 5134 Nm and power factor of 0.9 create parameters suitable for drives with a high demand for stability. Efficiency of 96.1 % supports economical operation and at the same time helps reduce energy losses in long production cycles.

For modernisation, the mechanical side is also decisive. Frame size 450 mm provides a solid foundation for applications where high load and precise installation of the motor into the existing technology are expected. Weight of 5000 kg, rotor inertia of 13.0 kg·m² and a rotor cage made of copper bars are parameters that support robust behaviour during starting as well as during steady running. Bearings 6328-C3 on both the DE and NDE sides help maintain reliability under industrial load.

Safer supervision of operation and thermal protection

• 6x PT100 in the winding allows more precise monitoring of stator temperature.
• PT100 in both the DE and NDE bearing extends control to the bearing assemblies as well.
• Anti-condensation heater helps reduce the risk of moisture during shutdown.
• 3x PTC complements the sensor equipment for motor protection during critical overheating.

This equipment improves operational predictability and supports safer supervision of the motor in an environment where downtime is costly. Insulation class F together with temperature rise B meets the requirements for long-term operation in industrial conditions and makes integration into plant control systems easier.

Use in drives for heavy-duty operation

The motor is suitable for drives for heavy industry as well as for an electric motor for universal industrial applications, where stable torque, resistance to load and suitable compatibility with medium-voltage infrastructure are decisive. In practice this may include pumps, fans, compressors, mixers, crushing lines, conveyor units, process aggregates, drives in cement plants, metallurgy, power generation, water treatment, raw material processing and other operations with continuous duty. For specialist projects, it is important that the 6000 V electric motor can be integrated into existing systems without unnecessary compromise in terms of power reserve.

Parameters that support the right choice

When selecting a motor, it makes sense to monitor not only the output, but also the overall operating logic of the machine in question. Model H17R-450-A-4-6 combines 800 kW, 1488 rpm, medium-voltage supply and well-considered temperature monitoring, which is beneficial for technology suppliers and industrial businesses dealing with drive replacement. VYBO Electric builds on its own research and development and on the manufacturer’s many years of experience in the field of industrial electric motors, which is why this type is suitable as a reliable foundation for an investment that you need to keep under control in the long term; if you are planning a replacement or a new project, please request a quotation.
