The SEW EURODRIVE SF77DRN90L4/BE2HR/TH is a helical-worm gearmotor designed for robust industrial applications. This unit belongs to the SEW EURODRIVE 77 series, indicating a specific frame size and gear reduction ratio. The part number decodes to a 4-pole motor, suggesting a nominal speed of approximately 1500 RPM at 60Hz or 1200 RPM at 50Hz, before gear reduction.

Technical details

• Series: SF77
• Motor Type: 4-pole asynchronous motor
• Gear Type: Helical-worm
• Voltage Class: The specific voltage class (e.g., 230/460V) is not explicitly defined by the provided part number and should be verified against the manufacturer's datasheet.
• Power Rating: The "90L" designation typically refers to the motor frame size and power output. For precise wattage, consult the manufacturer's specifications.
• Enclosure Type: The "BE2HR" and "TH" suffixes likely denote specific features such as a brake (BE2), a specific terminal box orientation (HR), and potentially a thermal protection or special winding (TH).
• Mounting Configuration: The part number does not explicitly define the mounting orientation (e.g., foot-mounted, flange-mounted).

Applications & compatibility

This SEW EURODRIVE gearmotor is suitable for applications requiring high torque and low output speed, commonly found in material handling systems, conveyor belts, packaging machinery, and other industrial automation equipment. Its helical-worm gearing provides a compact and efficient solution for speed reduction.
