Schneider Electric BCH18LH20332A6C Easy Lexium 18 BCH18 2.0 kW 6.37 N·m 3000 rpm 100 mm 23-Bit Servo Motor

The Schneider Electric BCH18LH20332A6C is a low-inertia Easy Lexium 18 BCH18 servo motor rated for 2.0 kW continuous power. It delivers 6.37 N·m nominal torque at 3000 rpm (6000 rpm maximum mechanical speed), draws 13.2 A continuous stall current, and uses a 23-bit incremental encoder on a 100 mm flange without a holding brake.

Selection Notes

This no-brake, incremental-encoder BCH18 variant matches the 2.0 kW LXM18 servo drive at its 13.2 A continuous current rating — size the drive to this figure, not the 41 A maximum permanent current, which is a short-duration limit rather than a continuous one. The 23-bit incremental encoder resolves position finely enough for closed-loop motion but loses absolute position on power-down, so the application needs a homing routine at startup; the multi-turn encoder variant in the same power class removes that step. Without a holding brake, the axis free-wheels the instant drive power drops, so this version suits horizontal axes where gravity will not pull the load out of position. Peak stall torque of 19.1 N·m covers acceleration bursts roughly 3x above the 6.37 N·m continuous rating, and the 2.64 kg.cm² rotor inertia keeps this frame suited to moderately dynamic profiles.
