In heavy manufacturing, pumps, compressors and mills, the decisive factors are stability, starting reserve and thermal resistance. H17R-500-B-4-6 is a solution for operations where a 1400 rpm electric motor must deliver compact power without unnecessary downtime. In this power class, it is suitable wherever 1400 kW drives systems with long daily loading and where predictable drive response is important.
1400 rpm electric motor for demanding production sections
For process lines with high operating continuity, the torque profile during starting and load changes is also essential. This high-voltage electric motor is designed to handle use in 6 kV industrial drive networks while retaining reserve capacity for the actual load of the technology. The copper rotor helps limit losses in the rotor winding, resulting in lower heating and longer operating endurance during repeated cycles.
Efficiency reflected in operating costs
In energy-intensive operations, every percentage point of efficiency has a direct impact on energy bills as well as the thermal load of the machine. IE4 Super Premium efficiency helps keep consumption under control in applications where the motor operates practically continuously. From a maintenance perspective, the balanced operation of the four-pole electric motor is also beneficial, as it is better suited to the standard requirements of industrial units with a rated speed of around 1492 revolutions per minute.
Durability required by heavy-duty operations
The 500 mm frame size provides a structural basis for robust installation in applications with higher mechanical loads. In practice, this is appreciated wherever the motor is exposed to vibration, dust or increased humidity. Special protection for demanding environments is available in IP56, IP65, IP66 and IP67 versions, allowing the drive to be adapted to the specific application without compromising protection of mechanical parts.
Design prepared for long-term loading
A rated current of 153,9 A together with a rated torque of 8961 Nm creates the conditions for stable operation of large units. The starting characteristic is also important for drive design, making this model suitable wherever the mechanics of the technology must be respected while maintaining a smooth start. A weight of 7040 kg and rotor moment of inertia of 35,0 kg·m² support robust behaviour in heavy industrial operation.
Temperature control and service points in one solution
Insulation class F together with temperature rise B create a reserve for long operating cycles in which winding stability is essential. Available accessories also assist routine maintenance, as temperature sensing and bearing monitoring simplify service planning without unnecessary downtime. VYBO Electric has supplied motors for industrial applications for many years, where consistent operation and precise service support are required.
Use in processes where continuous operation is decisive
This model is suitable for large-scale operations where power must be reliably transferred into a stable technological process. It is suitable for the following applications:
- Cement mill with high load during continuous crushing.
- Compressor station for process gas in a refinery.
- Pumping assembly for cooling water in the energy sector.
- Ventilation unit for flue-gas extraction in metallurgical operations.
- Rolling-table drive in a steelworks.
- Agitator in a chemical reactor with demanding starting conditions.
- Blower for an industrial waste incinerator.
- Hammer crusher in a quarry operation.
- Extruder in a polymer production line.
- Dewatering pump in the mining industry.
