 High-performance SEW-EURODRIVE Helical-Worm Gearmotor designed for precise, variable-speed industrial applications.

Technical Breakdown & SpecificationsGear Unit Series (ST57/T): The "S" designates a helical-worm right-angle gearbox. The T indicates a torque arm mounting configuration (often used for shaft-mounted configurations).

• Motor Model (DRN80M4): A premium-efficiency, 4-pole AC asynchronous motor configured for three-phase power supplies
• Speed Reduction (1751 -> 71 RPM): The base motor runs at 1751 RPM at standard 60Hz frequency. The internal gearbox reduces this output down to 71 RPM, creating a substantial mechanical advantage.
• Power & Electrical: Rated at 1 HP. It is dual-voltage capable, pulling 3.1 Amps at 230V or 1.56 Amps at 460V
• Duty & Torque: Rated for Continuous S1 Duty, meaning it is engineered to run non-stop under full load without exceeding thermal limits. It delivers a massive 1950 in-lbs of torque at the output shaft due to the high gear reduction ratio.
• Control Compatibility: Rated for Inverter Duty (VPWM), indicating that its insulation system is designed to handle the voltage spikes and heat generated by Variable Frequency Drives (VFDs) utilizing Voltage Pulse Width Modulation.
  

The SEW-EURODRIVE Gear Motor Model ST57/T DRN80M4 is a reliable helical-worm gear motor suited for industrial applications requiring precise variable speeds.
