Schneider Electric BCH18LF07332A5C Easy Lexium 18 BCH18 750 W 2.39 N·m 3000 rpm 80 mm 23-Bit Servo Motor

The Schneider Electric BCH18LF07332A5C is an Easy Lexium 18 BCH18 servo motor rated for 750 W continuous power. It delivers 2.39 N·m continuous stall torque at 3000 rpm (max mechanical speed 6000 rpm), draws 5.1 A continuous stall current, and mounts on a 80 mm flange without a holding brake. Peak stall torque reaches 7.17 N·m for short acceleration bursts, and the 23-bit incremental encoder with IP67 sealing suits enclosed motion-control axes on a matched LXM18 servo drive.

Selection Notes

This is the low-inertia (L) build of the 80 mm BCH18 frame, so it favors fast acceleration and deceleration over sheer inertia-matching mass — use the 0.78 kg.cm² rotor inertia figure above, not the housing dimensions, when checking the load-to-rotor inertia ratio for the driven axis. The 23-bit incremental encoder needs a homing move after every power-up; choose the multi-turn version of this frame if the application cannot tolerate a re-reference cycle. Without a holding brake, the axis free-wheels the moment drive power is removed, so pick the braked variant of this frame for vertical or suspended loads that must not drop on an e-stop. Size the matching LXM18 servo drive to the 5.1 A continuous stall current, not the 7.17 N·m peak stall torque, which only applies for short acceleration bursts.
