Stepper motor 28BH75EC018IE

with integrated driver and coderNEMA 11with built-in encoder

Overview
This 28 mm EtherCAT integrated stepper servo combines motor, drive and encoder into a single 74.5 mm body. EtherCAT and TTL connectivity with 16,384-count encoder feedback enable compact closed-loop positioning for transfer, packaging and small automation axes while minimizing external wiring and system footprint.

KEY HIGHLIGHTS
