Feature → Business Impact → Application: The 250 kW output at 400 V in a water-cooled SynRM design reduces energy consumption in high-load drives, delivering measurable life-cycle cost savings and improved plant efficiency. This is especially beneficial in continuous operations like extrusion, pumps, and conveyors where cooling load can tax system reliability. The IE4 efficiency class translates to lower operating heat and reduced chiller duty, enabling smaller cooling infrastructure and lower total cost of ownership. The IP55 enclosure provides robust protection in dusty or wet environments, reducing unscheduled downtime in mining equipment and metal processing lines. The 6315/C3 bearing arrangement and NDE 6213/HC5C3 bearings contribute to extended maintenance intervals and smoother operation in demanding applications. The D-End top terminator box simplifies electrical installation, improving wire routing, reducing installation time, and enabling rapid retrofits in existing plants. The motor’s 4-pole design optimizes speed and torque for medium- to high-torque applications, improving control precision in material handling and packaging lines. With a Finland-origin manufacturing pedigree, you gain traceability, consistent quality, and access to ABB support for complex automation projects. This combination of features supports long-term reliability, compliance with industry standards, and a clear reduction in operating expenses for industrial automation projects. Long-term compatibility with 50 Hz 400 V systems, 4-pole configurations, and standard IEC hardware ensures seamless integration with existing control architectures and drive systems.

FAQs
Yes. The motor is specifically designed for 400 V, 50 Hz supplies and uses a D-End top terminal box to simplify wiring. Verify shaft alignment, flange compatibility, and matched couplings with your drive system to ensure a smooth retrofit or new installation.
Key specs include 250 kW output, 4 poles, 50 Hz, 400 V input, IP55 protection, IE4 efficiency, and IC71W insulation. The motor is water-cooled SynRM, with a net weight around 651 kg and a gross weight of 661 kg, designed for demanding continuous operation.
Industries like metals, mining, plastics, and heavy process automation benefit due to high efficiency and reliable cooling under heavy loads. Use cases include high-torque conveyors, pumps, and extruders where energy savings and reduced thermal loading improve overall plant reliability and throughput.
The motor meets IE4 efficiency and IP55 protection, with IC71W insulation class. The stainless-steel or welded steel frame and robust bearings support operation in harsh environments, while the product’s country of origin (Finland) supports traceability and quality assurance in regulated industries.
Maintenance is streamlined by rugged bearings (6315/C3 and 6213/HC5C3), a durable welded-steel frame, and a top-terminal box for easier wiring. The energy savings from IE4 efficiency, combined with reduced cooling loads due to water cooling, typically deliver a favorable return on investment over typical motor replacement cycles.
