H17R-500-D-4-6 brings high power density to operations, which large factories need when machine-room space is limited. This 1400 rpm electric motor with an output of 1800 kW is designed to handle stable loads in heavy industry without requiring an disproportionately large installation footprint. In practice, this means easier integration into existing lines, less impact on the layout and better utilization of invested space. As a 6000 V electric motor, it is intended for applications where efficient energy transmission over longer distances and sensible sizing of power distribution are taken into account. In sectors where the reliability of process drives is decisive, such a concept has a direct impact on technology availability. With this solution, VYBO Electric builds on experience from environments where drive technology must operate continuously and with predictable behaviour.
Compact 1400 rpm electric motor for installation in limited space
The compact design is one of the main reasons why this machine finds a place in projects with high integration requirements. Output within sizes from H315 to H560 makes it possible to design a solution that does not require unnecessarily extensive technological units. For both the designer and maintenance team, this means easier handling, better access to service points and fewer compromises when positioning the machine in a hall. A four-pole electric motor with this concept provides balanced operation suitable for applications with long working cycles and repeated starts. Operators who want to combine output, reserve capacity and economical space requirements in one machine will also value its use in such cases.
In heavy industry, the requirement for high torque often coincides with the effort to keep operation technically clean and serviceable. This is precisely where a three-phase electric motor is suitable, transferring energy into the process without unnecessary fluctuations. Efficiency of 96,8 % helps reduce losses in long-term operation, while a power factor of 0,91 supports sensible grid loading. Rated torque of 11506 Nm provides confidence during starting as well as under loads that change over time in process operations. Rated current of 197,2 A and a starting current ratio of 6,8 % fit a drive design in which the behaviour of power distribution and protective elements is also monitored.
Copper rotor for long service life in continuous operation
Copper strip in the rotor cage contributes to lower losses and better heat dissipation under long-term load. In operations where the motor is repeatedly exposed to thermal cycles, this is an important prerequisite for stable service life without unnecessary interventions. In industrial drives, this reduces the risk of excessive heating, which is one of the main causes of premature wear. Insulation class F together with temperature rise B create reserve capacity for use in environments with higher thermal-resistance requirements. A weight of 7330 kg and rotor moment of inertia of 39,0 kg·m² indicate a robust design suitable for equipment where running stability and resistance to dynamic loading are valued.
Frequency selection option for operation at both 50 Hz and 60 Hz
The option to set the frequency simplifies deployment in international operations where different standards and technological units meet. Availability for 60 Hz expands the machine’s usability without the need to change the entire drive concept. For large process lines, conveying systems and pumping assemblies, this is a practical advantage because the project does not have to stop at the boundary of the local grid standard. High operating flexibility is especially valuable where technology is gradually modernized and compatibility with existing machines must be maintained.
Monitoring motor condition in demanding operation
During long production cycles, it is important to keep the temperature of both the winding and bearings under control because these points determine how the motor behaves over time. Available sensing supports better maintenance planning and reduces the risk of unplanned shutdowns in plants operating continuously. Combined with the high-voltage design and durable rotor, this creates a solution suitable for environments where long-term stability is expected. VYBO Electric ISO certificates are part of the production and inspection procedures, supporting confidence when deploying the motor in critical technological nodes.
Typical applications include:
- Centrifugation in cement mills with high inertia.
- Main drive of rolling lines in metallurgical operations.
- Pumping units for cooling circuits in the energy sector.
- Fan stations for flue-gas desulphurization.
- Compressor units in chemical gas processing.
- Raw-material crushers in stone-processing and mining operations.
- Belt conveying systems for bulk materials in port terminals.
The design combining an output of 1800 kW with high efficiency gives operations room for long-term planning without unnecessary energy losses. In applications with variable load, the rated speed of 1494 rpm also has an effect, helping maintain a suitable balance between output and operating dynamics. From a maintenance perspective, it is also valuable that the motor is designed for clearly structured service interventions in technical spaces where speed and predictability matter.
