The SEW R47DRN100LS4 is a high-performance helical AC gear motor compliant with European CE standards (50 Hz). Equipped with an IE3 high-efficiency four-pole motor, it delivers a rated power of 3 horsepower (approximately 2.2 kW) and is designed for continuous S1-100% operation.
Featuring a compact foot-mounted design, this model achieves an overall gear ratio of 19.27, precisely reducing the motor’s input speed of 1450 rpm to an output speed of 75 rpm. It generates an output torque of 2480 LB-in and, with a service factor of 1.05, can reliably withstand an overhung load of 795 Lb, making it ideal for medium to heavy-duty smooth operation applications.
The motor maintains a stable efficiency range of 86.4%–87.5% under varying loads, offering excellent energy savings. Its 3020 traffic red finish and flexible terminal box and cable entry design simplify installation and maintenance. Widely used in material handling, light machinery, and automation lines, it is a reliable solution for industrial drive needs.
