Schneider Electric BCH18MB0133CF5C Easy Lexium 18 BCH18 100 W 0.32 N·m 40 mm Brake Multi-Turn Servo Motor

The Schneider Electric BCH18MB0133CF5C pairs the 100 W, 0.32 N·m Easy Lexium 18 BCH18 motor frame with a 23-bit multi-turn absolute encoder and an integrated 0.35 N·m holding brake. Continuous stall current is 1.1 A on the 40 mm flange, medium-inertia (0.076 kg.cm²) rotor. The absolute encoder keeps position data after a power loss, and the brake holds the axis once drive torque drops out.

Selection Notes

This variant stacks both options onto the 100 W, 40 mm-flange frame: a 23-bit multi-turn absolute encoder so the axis never needs re-homing, and a 0.35 N·m holding brake so a vertical load does not drop when the drive disables. The combination adds weight — 0.69 kg against 0.43 kg for the brakeless BCH18MB0133CA5C — which matters on a fast-moving low-mass axis but is a fair trade on a lift or Z-axis application. Drive sizing follows the 1.1 A continuous stall current, with the 3.9 A maximum permanent current reserved for short accelerations. As with the rest of the medium-inertia M-series motors in this range, it is built for load-inertia-matched axes rather than very fast point-to-point cycling. Maximum mechanical speed is rated to 6000 rpm, twice the 3000 rpm nominal speed used above, which leaves margin for brief overspeed during deceleration moves. IP67 sealing and the two-connector male/female power and feedback interface are shared across the Easy Lexium 18 BCH18 range, so this fully-optioned 100 W motor uses the same cabling and enclosure design as the brakeless and lower-spec variants.
