IE4 Super Premium efficiency helps reduce energy losses in heavy-duty operation and maintains power reserve even in processes where the motor operates under stable load for long periods. Model H17R-400-A-2-6 with an output of 500 kW is prepared for operations that consider every kilowatt-hour in the context of continuous production and expect reliable running without unnecessary downtime. In practice, this is a solution for drive technology where the combination of efficiency, a solid mechanical concept and a precisely selected operating point is important.
3000 rpm electric motor for economical operation of large lines
At a rated speed of 2978 rpm, the 3000 rpm electric motor performs well where the technological system must run smoothly and without unnecessary fluctuations in output. This high-voltage electric motor is suitable for systems where firm engagement and long-term resistance to operating load are expected from the drive. From the perspective of OEM manufacturers, it is also important that the design is intended for use in demanding industrial assemblies where efficiency, service accessibility and repeatable installation logic are monitored.
Compact solution for 6 kV applications
The 6000 V electric motor in this version delivers full output within a package that saves space in the line layout and makes integration into existing technological systems easier. The 400 mm frame size supports a compact solution without unnecessarily increasing the machine’s space requirements. The two-pole electric motor is also suitable for applications where direct power transmission and stable operation at high speed are required. In practice, customers also appreciate the frequency selection option because the equipment can be prepared for 60 Hz operation according to export projects or specific halls.
Durable construction for continuous industrial operation
The high-voltage electric motor from VYBO Electric is based on a concept designed for long-term operation in factories where winding temperature, bearing temperature and overall service load are monitored. Insulation class F combined with temperature rise B provides suitable reserve for demanding cycles in which the drive should not overheat during repeated starts or under steady-state load. The rotor cage made of copper strip supports robust starts, while 6319-C3 bearings on both the DE and NDE sides contribute to stable rotor guidance during long-term running.
Condition monitoring that service teams need
For operators of large factories, machine-condition monitoring is also important, which is why 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistors are available. Such equipment helps evaluate operating conditions more effectively and respond to deviations before they affect production. Combined with VYBO Electric’s ISO certificates, this provides a practical basis for projects requiring traceability, service discipline and repeatable delivery quality.
Deployment in technologies with higher loads
This 3000 rpm electric motor is suitable for applications where output must be transmitted without compromising process stability. Rated torque of 1603 Nm, a power factor of 0,9 and efficiency of 95,8 % support economical operation during long running periods. A weight of 3630 kg and rotor moment of inertia of 4,300 kg·m² correspond to a massive concept that helps damp dynamic changes in the system. Manufacturing practice in this segment requires precise coordination of the drive with the technology, and this is where the benefits of a design intended for heavier industrial deployment become evident.
Applications suitable for this assembly:
- Main drive of a cement mill.
- Stone-crusher drive in a quarry line.
- Compressor unit for process air.
- Cooling-tower fan in an energy unit.
- Exhaust fan in a waste incinerator.
- Raw-water pump in a water-treatment plant.
- Process pump in chemical production.
- Raw-material mill in a metallurgical plant.
- Extruder for plastic granules in a production line.
- Briquetting press in recycling technology.
- Drying drum in the paper industry.
- Screw conveyor for bulk materials.
- Mixer drive in a large chemical vessel.
- Centrifugal blower for industrial filtration.
In operations where shutdowns and energy costs are both decisive, solution availability and service reliability are important. VYBO Electric therefore supplies the motor as part of the H17R Compact PRO-HV platform with an emphasis on integration into large technological systems and long-term reliability in operating modes that place high demands on the drive. Order it in good time so it can be prepared for your project without delay.
