Schneider Electric BCH18MD04332A5C Easy Lexium 18 BCH18 400 W 1.27 N·m 3000 rpm 60 mm 23-Bit Servo Motor

The Schneider Electric BCH18MD04332A5C is a 400 W Easy Lexium 18 BCH18 servo motor delivering 1.27 N·m continuous stall torque at 3000 rpm nominal speed, drawing 2.6 A continuous stall current. It uses a 23-bit incremental encoder on a 14 mm shaft, mounts on a 60 mm flange, and ships without a holding brake.

Selection Notes

At 400 W the BCH18MD04332A5C is the higher-torque step in the 60 mm-flange BCH18 family, delivering 1.27 N·m continuous stall torque versus 0.32 N·m on the 100 W motor in the same frame. The 23-bit incremental encoder means the controller must run a homing routine at startup or after any uncommanded stop; choose the multi-turn-encoder variant instead if the axis cannot tolerate that. No brake is fitted, so an external brake or self-locking mechanism is needed wherever the axis must hold position without drive power. Size the Lexium 18 (LXM18) drive's continuous current to 2.6 A, with 5.9 A maximum permanent current available for short accelerating moves. The larger 0.328 kg.cm² rotor inertia and 254 N maximum radial force rating let this motor carry more reflected load inertia and side-load than the 100 W variant while keeping the same 60 mm flange footprint. IP67 sealing and the two-connector male/female power and feedback interface match the rest of the Easy Lexium 18 BCH18 range, so cabling and enclosure design stay the same across the family regardless of power rating.
