Water-cooled SynRM design minimizes heat buildup in high-power drives, enabling steady 315 kW output with lower derating and longer service life. The business impact is a smaller cooling burden and increased uptime in continuous production lines, such as process cooling or material handling applications. IE5 efficiency delivers measurable energy savings across the motor’s operating profile, reducing utility costs and improving plant-wide energy intensity metrics while maintaining performance at 50 Hz. The IP55 enclosure and IC71W insulation provide rugged protection against dust, moisture, and thermal stress, ensuring reliability in harsh environments and simplifying compliance with industrial standards. A welded steel frame (250) and robust bearings (6312/C3) offer mechanical rigidity, lower vibration, and extended maintenance intervals, translating into lower lifecycle costs. The D-connection configuration and 400 V operation support seamless electrical integration with standard ABB drives, controls, and panel architectures, while the 4-pole design enables efficient low-speed torque with precise control. Terminator box location (D-End top) and IM classes (IMB3 IM1001) enhance installation ease, reducing commissioning time and field wiring errors. Overall, the motor’s combination of premium efficiency, strong enclosure, and thoughtful mechanical layout aligns with OEM requirements for reliability, safety, and total cost of ownership improvements in industrial motors and electrical drives.
