The SEW EURODRIVE R37-DRS71M4BE1HR/TH is a helical gearmotor designed for robust industrial applications requiring precise speed reduction and torque multiplication. This unit belongs to the R series of gear reducers, known for their compact design and high efficiency. The "DRS71M4" designation indicates specific motor and gear unit characteristics that define its performance envelope.

Technical details

• Gear Unit Series: R Series (Helical)
• Motor Frame Size: 71M
• Motor Poles: 4-pole (indicating a nominal motor speed of approximately 1500 RPM at 60Hz)
• Motor Type: BE1 (likely indicating a standard AC motor with specific insulation class and enclosure)
• Additional Designation: HR/TH (These suffixes typically denote specific motor options or environmental ratings; consult the manufacturer's datasheet for precise definitions of HR and TH.)
• Mounting Type: Foot-mounted (common for R series gear units, though flange mounting may also be an option depending on the full part number configuration)
• Service Factor: The R37 designation implies a specific gear ratio and torque capacity. For precise service factor and output torque, refer to the SEW EURODRIVE technical documentation for the R37 ratio.
• Voltage/Frequency: While not explicitly stated in the provided information, 4-pole motors of this frame size are commonly available in 230/460V or 208-230/460V configurations for 60Hz operation. Verification against the manufacturer's datasheet is recommended.
