Schneider Electric BCH18LH2033CA6C Easy Lexium 18 BCH18 2.0 kW 6.37 N·m 3000 rpm 100 mm Multi-Turn Servo Motor

The Schneider Electric BCH18LH2033CA6C 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 carries a 23-bit multi-turn absolute encoder on a 100 mm flange without a holding brake.

Selection Notes

This no-brake, multi-turn-encoder BCH18 variant matches the 2.0 kW LXM18 servo drive at its 13.2 A continuous current rating, the same drive class as the incremental-encoder version in this power range. The 23-bit multi-turn absolute encoder retains position through power cycles, so the axis skips the homing routine that the incremental-encoder variant needs at every startup. With no holding brake, the motor free-wheels once drive power is removed, which is acceptable on horizontal axes but not where a load must hold position unpowered — pick the brake-equipped version of this variant for that case. Peak stall torque of 19.1 N·m supports acceleration bursts roughly 3x above the 6.37 N·m continuous rating, and the 2.64 kg.cm² rotor inertia matches the incremental-encoder version exactly, so dynamic performance is unaffected by the encoder choice. The 100 mm flange and 22 mm parallel-key shaft stay fixed across every encoder and brake option in this power class, so only electrical wiring to the drive changes between variants.
