Schneider Electric BCH18LM3033CF6C Easy Lexium 18 BCH18 3.0 kW 9.8 N·m 130 mm Brake Multi-Turn Servo Motor

The Schneider Electric BCH18LM3033CF6C is a 3 kW Easy Lexium 18 BCH18 servo motor delivering 9.8 N·m continuous stall torque at 18.6 A continuous stall current. Built on a 130 mm flange with a low-inertia rotor (8.3 kg.cm²), it suits fast point-to-point cycles. An integrated holding brake and a 23-bit multi-turn absolute encoder round out this variant for applications that need reliable position retention through a power loss.

Selection Notes

This is the only low-inertia motor in the Easy Lexium 18 BCH18 range covered here — the 8.3 kg.cm² rotor accelerates and decelerates faster than the medium-inertia M-series frames, which makes the BCH18LM3033CF6C the better fit for fast point-to-point or pick-and-place cycles rather than large, inertia-matched load axes. Pair it with a Lexium 18 (LXM18) drive sized for its 18.6 A continuous / 56.0 A maximum permanent current rating; undersizing the drive's continuous current will trip the motor's thermal protection well before the 29.4 N·m peak torque is reached. The integrated 20.0 N·m holding brake is sized to hold the 11.8 kg rotor and any coupled vertical load when the drive is de-energized, and the 23-bit multi-turn encoder keeps axis position after an e-stop or power cycle without a re-homing move. Choose this 3 kW frame over the lower-power M-series motors in this line when the application needs continuous torque above roughly 5 N·m; below that, a medium-inertia 60 mm or 80 mm flange motor from the same range matches typical ball-screw or belt load inertia better. The two male/female connectors used for power and feedback are the same connector system across the whole Easy Lexium 18 BCH18 range, so cabling and connector stock do not change when this 3 kW frame replaces a lower-power motor on a redesigned axis. Maximum mechanical speed is rated to 6000 rpm against the 3000 rpm nominal speed used for the ratings above, leaving headroom for brief overspeed during deceleration. IP67 sealing also means the motor tolerates washdown or swarf exposure without a separate enclosure.
