Stepper motor 57BH83EC12IE

60 V24 Vwith integrated driver and coder

Overview
The 57BH83EC12IE is a 57 mm (NEMA 23) EtherCAT integrated stepper servo delivering up to 1.2 N·m of output torque. It integrates motor, drive electronics and encoder feedback in a compact body to simplify wiring and reduce external drive hardware in transfer, packaging and multi‑axis automation systems.
