SEW-EURODRIVE R40DT80N4 Gearmotor

SEW-EURODRIVE R40DT80N4 gearmotor is a 1 HP, three‑phase AC drive built around SEW’s R40 frame with a DT80 gear reducer, delivering a TEFC (Totally Enclosed Fan-Cooled) enclosure and a B8 mounting configuration with a TB-270 CE‑3 terminal box. In the commonly cited setup, it uses a 6.17:1 gear ratio and 230/460 VAC 3‑phase power, producing about 276 RPM at 60 Hz; other vendors list alternate configurations such as a 3.98:1 reducer that yields roughly 427 RPM at the same supply. There are also voltage variants reported, including 330/575 VAC, reflecting different regional specifications. The R40DT80N4 designation identifies a medium‑frame SEW gearmotor in which the motor and worm gear are integrated to provide compact torque for moderate‑load drives in automation, conveyors, and packaging lines. This model is typically offered with a TEFC enclosure for general industrial environments and mounting options compatible with B8 frame fixtures alongside a CE‑3 marked terminal box for electrical connections.
