The design of the H17R-315-D-4-6 motor with an output of 250 kW delivers energy efficiency appreciated by every operator in medium-sized companies and large factories who monitors consumption and drive stability. Even at the initial design stage, it is clear that this 1500 rpm electric motor is intended for long-term operation in heavier conditions where efficiency, thermal reserve and precise connection to the technology are decisive.
IE4 efficiency in practice for demanding drives
Industrial lines often operate under higher load throughout the shift, which is where IE4 Super Premium efficiency is useful. In operations with pumps, mixers, conveyors or compressors, every watt saved affects long-term costs. Drive technology in this segment requires a motor that maintains its parameters even under repeated load and does not require compromises in sizing.
The high-voltage electric motor from VYBO Electric is designed to be ready for integration into technological systems with higher requirements for operating reliability. The 6000 V electric motor is suitable where direct power transfer into demanding technology is expected without unnecessary oversizing of auxiliary components. The customer therefore gets a solution that fits projects focused on efficient operation and cost control more effectively.
Compact 6 kV motor for broader use in machinery
The compact 6 kV motor with a 315 mm frame size provides a space-saving solution for designs where installation discipline and easier integration into existing assemblies are important. From a design perspective, the four-pole electric motor helps maintain a suitable ratio between speed and torque, which matters in drives with smoother starting and stable power transmission. The frequency-selection option simplifies use in projects with a different network standard or export installations.
Operations where such a motor can be used include mixing and homogenisation lines, heavily loaded belt conveyors, water pumping stations, process fans, continuously operating crushers, rolling units, centrifuges, mixing vessels in the chemical industry, grinding stations, drying units, compressor stations, extruders and mill drives in processing operations.
Rated torque for stable starting of technology
Rated torque of 1612 Nm helps maintain confidence during starting and under variable load, which is a practical difference in industrial drives. Rated current of 28,9 A supports power-supply and protection design, while a rated speed of 1481 rpm provides a good basis for applications that need a balanced operating point. The starting ratio, breakdown ratio and starting current together create a picture of a motor that can be predictably integrated into the calculation of the entire system.
Bearings, insulation and thermal reserve during long shifts
6322-C3 bearings on both the DE and NDE sides help handle longer operating intervals with an emphasis on mechanical precision. Insulation class F together with temperature rise B provide reserve for more demanding thermal regimes common in large technological systems. Copper strip in the rotor cage supports robust behaviour when transferring energy to the load and is also important during repeated starts in industrial production.
VYBO Electric works with ISO certificates as part of a process that is important to engineers and designers when selecting a motor for a project. A weight of 2970 kg and rotor moment of inertia of 4,9 kg·m² must be considered when designing the foundation, handling and connection to the technology. If winding and bearing monitoring is part of the project, elements such as 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistors are also available.
VYBO Electric for projects where long-term economy is decisive
This 1500 rpm electric motor is prepared for integration into new lines and modernisations where long-term economy and service predictability are monitored. The combination of efficiency, power reserve and construction for higher voltage makes it a solution for technologies that must run steadily throughout the entire production campaign. If the drive is to be ready for deployment without unnecessary delays, order it as soon as possible and secure timely delivery to the project.
