Electric motor 1000 kW, 1490 rpm, 6000 V, H17R-450-C-4-6 MV

Compared with a standard solution for heavy-duty drives, the H17R-450-C-4-6 delivers more reliable operation where the production line must run without unnecessary downtime. This model, with an output of 1000 kW, operates in the speed range of 1400-1500 rpm and is designed to handle long-term load in power generation, metallurgy, and processing technologies. For integrators, it is important that this is a medium-voltage asynchronous electric motor, combining a robust design with an operational reserve for demanding starts and rated load.

Operational certainty at high output and 6000 V

The model is intended for a 6000 V supply, while VYBO Electric also supplies solutions for voltage levels of 3.3 kV, 10 kV and 11 kV according to project requirements. In practice, this means easier adaptation to existing infrastructure and fewer compromises in drive design. For OEM manufacturers of equipment and operations with a medium-voltage network, it is also an advantage that the 6000 V electric motor can be used in applications where emphasis is placed on smooth starting, precise sizing and long-term stability. An efficiency of 96.2 % and a power factor of 0.9 support economical operation without unnecessary energy losses, which is especially appreciated by energy-efficient industrial motors.

Design ready for heavy industrial deployment

The frame with a size of 450 mm and IEC frame design provides good support for mechanical integration into pumps, compressors, mills and other technological units. A rated current of 111.5 A, rated torque of 6409 Nm, rotor inertia of 16.0 kg·m² and copper bars in the rotor cage create the conditions for steady and predictable operation. Insulation class F together with temperature rise B increase the winding’s resistance to thermal load, while 6328-C3 bearings on both the DE and NDE sides support reliable operation in long duty cycles.

Technical features that help with maintenance and diagnostics

The motor is equipped with thermal protection with 6x PT100 in the winding, PT100 in both the DE and NDE bearings, anti-condensation heating and 3x PTC, which simplifies condition monitoring and helps detect unwanted temperature changes in time. The high weight of 5450 kg is a natural consequence of the robust power section and must be taken into account already during the design of foundations, handling and installation. H17R-450-C-4-6 is therefore suitable wherever long-term load, stable control and technical readiness for demanding operating conditions are expected.

Industrial applications of the medium-voltage motor

• Pumping stations requiring long-term operation at stable speeds.
• Compressor units in energy and process plants.
• Mills and crushers with high load and impact torque during starting.
• Ventilation and blower systems in large facilities.
• Production lines in heavy industry with continuous operation.
• Drive units in projects where an electric motor for universal industrial applications is required.
