The SEW R57DRN90L4 is a highly efficient integrated drive solution combining a helical gear unit with an AC motor, compliant with European CE standards (50 Hz). It features an IE3 high-efficiency four-pole motor with a rated power of 2 horsepower (approximately 1.5 kW) and is designed for continuous S1-100% operation.
With a compact foot-mounted design, this model delivers an overall gear ratio of 21.93, precisely reducing the motor’s input speed of 1461 rpm to an output speed of 67 rpm. It generates an output torque of 1900 LB-in and, with a high service factor of 2.10, can reliably withstand an overhung load of 1150 Lb, making it ideal for heavy-duty and shock-load applications.
The motor maintains a stable efficiency range of 84.6%–86.1% 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 provides a reliable drive solution for industrial applications.
