FAQs
This motor uses a D-End top terminator box for wiring access, a 250 frame with a cast-iron housing, and a total weight around 340–350 kg. Plan for a sturdy base, proper mounting clearances, and a compatible VFD or starter suited for S1 duty. The reversible rotation option provides flexibility in tight installations and allows simple reorientation without changing wiring strategies.
Yes, the motor supports rotation on both ends, offering bidirectional operation. Direction control is achieved through correct three-phase wiring and protective interlocks. When wiring for reverse rotation, ensure the drive system, guards, and mechanical couplings accommodate the new direction and that all safety protocols are observed during commissioning.
The motor demonstrates IE1 efficiency at 50 Hz with Full Load around 92.1% and at 60 Hz around 93.0%, with slight reductions at partial loads. Energy savings come from its standard efficiency class and low-friction bearings. For continuous-duty applications like pumps and conveyors, typical life-cycle cost reductions are realized through lower operating energy and reduced maintenance needs.
Yes. The motor features IP55 protection and insulation class ICLF, designed for challenging environments. It operates at ambient temperatures up to 40 °C and up to 1000 m altitude, making it suitable for outdoor, dusty, or heat-intensive settings. The 4-pole, cast-iron frame also contributes to durability in demanding industrial applications.
With bearings 6215-2Z/C3 and 6212-2Z/C3, the motor provides low-friction operation and extended bearing life. The robust frame, standard spare parts, and readily available inventory reduce downtime and maintenance costs. For OEMs and end users, this translates to predictable maintenance planning, shorter downtime, and a favorable total cost of ownership.
