Schneider Electric BCH18MF0433CA5C Easy Lexium 18 BCH18 400 W 1.27 N·m 3000 rpm 80 mm Multi-Turn Servo Motor

The Schneider Electric BCH18MF0433CA5C is a 400 W Easy Lexium 18 (BCH18) servo motor rated for 1.27 N·m continuous stall torque at 3000 rpm nominal speed. It mounts on an 80 mm Asian standard flange, draws 2.6 A continuous stall current from a 220 V supply, and ships without a holding brake and carries a 23 bits optic multi turn encoder. The IP67-rated motor pairs with the Lexium 18 (LXM18) servo drive family.

Technical Specifications

Selection Notes

At 1.27 N·m continuous stall torque and 2.6 A continuous current, the BCH18MF0433CA5C fits light-to-medium load axes inside the 80 mm flange frame; the 4.45 N·m peak stall torque only covers brief acceleration, not sustained running. The multi-turn optic encoder tracks absolute position across several shaft revolutions, so the axis does not need a reference move after every power cycle. There is no holding brake on this variant, so it suits horizontal axes where the load cannot drift under gravity when power drops; a braked sibling in the same frame covers vertical or overhanging loads. The 200 W BCH18 covers lighter axes in the same frame; the braked version of this motor adds a holding brake for vertical loads.

Applications

Within the Lexium 18 line, the BCH18MF0433CA5C is sized for small pick-and-place arms, label and vision-inspection indexing, and light conveyor or feed axes where the duty cycle is high but the load inertia is low. Its 80 mm flange and 400 W continuous rating keep it in the same mechanical footprint as its sibling motors, so an LXM18 drive sized for this power level can be reused across the family without a mechanical redesign.
