Description
About the BCH18
About the BCH18
The Schneider Electric BCH18MD0433CF5C is the braked, multi-turn-encoder variant of the 400 W Easy Lexium 18 BCH18 motor: 1.27 N·m continuous stall torque, 2.6 A continuous stall current, 60 mm flange. A 2.0 N·m holding brake and 23-bit multi-turn absolute encoder are both integrated, and rotor inertia with the brake fitted is 0.54 kg.cm².
Selection Notes
This is the fully-specified 400 W motor on the 60 mm flange: a 23-bit multi-turn absolute encoder for position retention through a power cycle, and a 2.0 N·m holding brake for load-holding on a vertical or gravity-loaded axis. Rotor inertia with the brake fitted is 0.54 kg.cm², and net weight is 1.6 kg — the heaviest of the 60 mm-flange motors in this group. Continuous stall current stays at 2.6 A for Lexium 18 (LXM18) drive sizing. Choose the brakeless BCH18MD0433CA5C instead where the axis does not need mechanical holding and the extra 0.45 kg is not worth carrying. Maximum mechanical speed is rated to 6000 rpm against the 3000 rpm nominal speed used above, leaving margin for brief overspeed during deceleration. IP67 sealing and the shared two-connector power/feedback interface mean this motor drops into the same cabling and enclosure design as the rest of the 60 mm-flange Easy Lexium 18 BCH18 range despite carrying the highest power rating in that frame.
