IE5 efficiency class delivers measurable energy savings and reduced cooling demand, improving overall system efficiency and reducing operating costs in continuous-drive applications. This translates to lower energy bills and cooler equipment housing, enabling longer equipment life and less need for aggressive intercooling or after‑cooling solutions in industrial plants. The water-cooled SynRM design provides superior thermal management, allowing the 450 kW, 4-pole motor to sustain high torque and stable speed under heavy loads, which is essential for pumps and compressors in-process industries. In practice, users experience higher uptime, fewer thermal trips, and improved control precision for variable-speed drives in line with Industry 4.0 requirements. The aluminum frame and 315 frame size support easy integration with existing enclosures while maintaining strong mechanical stiffness for IMB3 IM1001 mounting, reducing vibration and bearing wear. IP55 protection ensures reliability in dusty or humid environments, and IC71W insulation supports long service life under demanding duty cycles. The 400 V/50 Hz, D-connection configuration aligns with standard industrial power systems, simplifying installation and spare-part provisioning. Overall, the motor delivers robust performance, easier maintenance planning, and a lower total cost of ownership in heavy‑duty automation scenarios.

FAQs
Yes. The motor is designed for 400 V input at 50 Hz and is suitable for 3-phase power with a D-connection configuration. It delivers 450 kW at 4 poles and a 370 V operating voltage, making it compatible with typical industrial electrical cabinets and drives. This aligns with standard ABB drive ecosystems for seamless integration and commissioning.
The unit is specified for up to 1000 m altitude and 40 °C ambient, with IP55 protection and an aluminum frame to aid heat dissipation. Installations should ensure adequate ventilation around the motor, proper water-cooling circuit integrity, and correct IMB3/IM1001 mounting alignment to minimize vibration and wear. D-End top terminator placement simplifies field wiring in confined spaces.
This motor features IE5 efficiency, IP55 enclosure protection, and IC71W insulation class, supporting reliable operation in harsh environments. It uses a 4-pole, 450 kW design with IMB3/IM1001 mounting. The product is designed for industrial duty (S9) and is compatible with 400 V/50 Hz systems, aligning with European standards and ABB’s certified drive architectures.
Water cooling enhances thermal management, enabling sustained high-load operation with reduced derating and cooler motor surfaces. This improves efficiency (IE5) and reduces cooling system load, translating to longer bearing life and fewer thermal trips. Maintenance focuses on the water circuit integrity, coolant quality, and routine inspection of bearings (6319/C3) and seals, supported by ABB’s IMB3 mounting framework.
Expect lower operating costs due to IE5 efficiency, which minimizes energy consumption at full and part loads. Reduced cooling requirements and improved thermal stability lower auxiliary equipment costs, while the robust construction and 1000 m altitude capability improve uptime in challenging facilities. A reliable supply chain for 400 V/50 Hz drives and spare parts further reduces maintenance downtime and downtime-related penalties.
