SEW-EURODRIVE RX57-DRN100L4-DH-1.92:1 Gearbox

SEW-EURODRIVE RX57-DRN100L4-DH-1.92:1 Gearbox is a preassembled RX57 servo gearmotor unit that pairs a DRN100L4 IE3 four-pole inverter‑duty motor with a RX57 single-stage gearhead, delivering a 1.92:1 reduction. The 3 HP motor is designed for inverter‑duty operation, enabling smooth acceleration, deceleration, and precise speed control. With a nominal input speed of 1,400 min^-1, the output shaft speed is approximately 729 min^-1, providing torque multiplication at reduced speed for controlled motion in automation equipment. The DRN100L4 designation confirms a 4-pole motor, and the assembly aligns with SEW's RX57 mounting interfaces for straightforward integration. This combination is suited to servo-driven applications in industrial environments where predictable speed and reliable torque at the driven load are required.
