Schneider Electric BCH18MM0813CA6C Easy Lexium 18 BCH18 850 W 5.39 N·m 1500 rpm 130 mm Multi-Turn Servo Motor

The Schneider Electric BCH18MM0813CA6C is an 850 W Easy Lexium 18 BCH18 servo motor built on the same 130 mm M130 flange as the BCH18MM08132A6C, rated for 5.39 N·m continuous stall torque at 1500 rpm nominal speed. It swaps the 23-bit incremental encoder for a 23-bit optic multi-turn feedback device, retaining absolute position after power loss, and ships without a holding brake.

Selection Notes

The BCH18MM0813CA6C matches the BCH18MM08132A6C's 850 W rating and 130 mm flange but swaps in a 23-bit optic multi-turn encoder, so the axis keeps its absolute position in memory through a power cycle and skips the homing move the incremental-encoder sibling needs. It still ships without a holding brake, so it fits a horizontal or counter-balanced axis rather than one that must hold a suspended load at standstill — the BCH18MM0813CF6C adds a 20.0 N·m brake for that case. Both motors share identical torque, current and shaft dimensions, so the choice comes down to encoder type and whether a brake is needed, and both draw up to 22.0 A maximum permanent current from the LXM18 drive at full stall torque. Net weight stays at 6.85 kg either way, since the encoder swap adds negligible mass over the incremental-feedback version.
