Description
SEW-EURODRIVE R27DT71D4TH Helical Gear Motor 1/3HP 230/460V 3-Ph 35RPM 890lb-in
The SEW-EURODRIVE R27DT71D4TH is a compact inline helical gear motor combining an R27 helical gearbox with a DT71D4TH three-phase AC motor. The R-series gearbox uses helical gear geometry to deliver smooth, quiet torque multiplication at a 48.17:1 reduction ratio, stepping the 1700 RPM motor input down to approximately 35 RPM output. With 890 lb-in of output torque from a 1/3 HP motor, this unit is representative of the compact, high-torque-density designs SEW-EURODRIVE is known for in industrial drive applications. This unit is sold AS-IS for parts or repair and has not been tested.

Applications
SEW-EURODRIVE R-series inline helical gear motors are widely used throughout industrial automation for applications requiring smooth, continuous torque at reduced speeds. Common deployments include conveyor drives, indexing tables, packaging machinery, material handling lines, filling and labeling equipment, and general-purpose machine drives. The hollow-shaft output with flange mounting is designed for direct shaft-mount installation onto driven equipment, eliminating the need for a separate coupling in many configurations. This type of gearmotor is a standard component in European-designed and ISO-standard machinery across food processing, automotive assembly, and light manufacturing environments.
The SEW-EURODRIVE R27DT71D4TH helical gear motor is in used condition and has been tested and verified to power on and run. This 1/3 HP unit shows typical cosmetic wear consistent with industrial use, including paint chips, surface rust on and around the output flange, and general grime on the housings. The junction box interior displays rust on the walls, though the terminal block and lead wires remain visible and intact. The output hollow-shaft flange exhibits rust and corrosion on the bolt circle and face. The unit is structurally complete and fully operational. Please review our complete photo set for detailed condition assessment. We may have multiple units of this item in stock; the unit you receive may vary slightly from the photos but is functionally equivalent and inspected to the same standard.
