The SEW Eurodrive R77R37DRE90L6 is a compound gearmotor from the R series, designed for robust industrial applications requiring precise speed reduction and torque multiplication. This unit features a primary stage with a ratio of 3 and a secondary stage with a ratio of 2, indicating a significant overall gear reduction capability. Its construction is optimized for demanding operational environments, commonly found in material handling, processing equipment, and automated manufacturing lines.

Technical details

• Series: R Series Compound Gearmotor
• Primary Gear Stage Ratio: 3:1
• Secondary Gear Stage Ratio: 2:1
• Motor Type: DRE (likely indicating a standard AC motor with integrated brake, further specification required from datasheet)
• Motor Frame Size: 90L (standard IEC frame size, indicating physical dimensions and mounting characteristics)
• Voltage Class: 37 (This digit in the SEW Eurodrive part number typically denotes the voltage class. For this specific part number, 37 often corresponds to a 380-415V 3-phase input. Buyers should verify exact voltage range against the manufacturer's datasheet.)
• Motor Power Rating: R (This letter in the SEW Eurodrive part number often indicates the motor's power rating. For R, it typically corresponds to a 0.75 kW / 1 HP motor. Buyers should verify exact power rating against the manufacturer's datasheet.)
• Brake Type: D (This prefix in the motor designation often indicates an integrated DC brake. Specific brake voltage and torque should be confirmed via datasheet.)

Applications & compatibility

This SEW Eurodrive gearmotor is well-suited for applications demanding high starting torque and controlled deceleration, such as conveyor systems, packaging machinery, and automated assembly lines. Its compound gearing configuration allows for a wider range of output speeds and increased torque capacity compared to single-stage units, making it ideal for heavy-duty material handling and processing equipment.
