FAQs
Yes. The 3GLL252947-ADM is specified for 400 V, 50 Hz operation and uses a D connection configuration. It supports IMB3 IM1001 mounting and a D-End top terminator box location, enabling straightforward on-site wiring, quick commissioning, and compatibility with common industrial automation installations.
The motor is rated IE4 for high-efficiency operation and carries IP55 protection for dust and water exposure. Insulation is IC LH with IC71W class, suitable for demanding environments. At 50 Hz, full-load efficiency is around 95.7%, with minimal loss across partial loads, supporting reliable performance in continuous duty drives.
Absolutely. The water-cooled SynRM design excels in high-heat, continuous-duty scenarios such as conveyors and pump applications. The IE4 efficiency and robust cooling reduce thermal stress, enabling longer service intervals, lower energy costs, and steadier torque under demanding load profiles.
Key classifications include IE4 efficiency, IP55 protection, insulation class ICLH, and IC71W winding class. The design also reflects robust mechanical standards (frame 250, IMB3/IM1001) and industry-typical protective features, making it well-suited for regulated industrial environments and automated production lines.
Expect improved energy savings from IE4 efficiency and longer intervals between maintenance due to robust insulation and protective features. The water-cooled design helps maintain stable operating temperatures, reducing wear on bearings and driveline components, which translates to lower total cost of ownership and faster payback in energy-intensive applications.
