SEW-EURODRIVE K57A gearmotor is an integrated drive that pairs a K-series gear unit (size 57) with a three-phase motor. It delivers a nominal output speed of 56.8 rpm when supplied by a three-phase AC source in the 330–575 V range and is rated at 3 HP. The K57A designation identifies this gearmotor size and configuration within SEW‑EURODRIVE's modular gearmotor family, reflecting SEW's engineering approach to provide reliable low-speed torque for industrial equipment.
