VFD vs Servo Drive: Key Differences
A side-by-side comparison of VFD and servo drive motor type, feedback, dynamic response, overload rating, cost, and applications for industrial engineers.
Adding a 2.0 N·m holding brake to the 200 W frame, the Schneider Electric BCH18MD02332F5C still delivers 0.64 N·m continuous stall torque at 1.6 A continuous stall current on the 60 mm flange. Rotor inertia rises to 0.328 kg.cm² with the brake fitted, and the 23-bit incremental encoder provides relative position feedback for this medium-inertia axis.
The holding brake adds 0.4 kg and raises rotor inertia from 0.268 to 0.328 kg.cm² against the brakeless BCH18MD02332A5C, but it keeps the 200 W, 60 mm-flange axis from drifting when the Lexium 18 (LXM18) drive is disabled — worth the extra mass on a vertical or gravity-loaded load. The 2.0 N·m holding torque matches the figure used across the other 60 mm-flange motors in this family, so one brake-release wiring design covers all of them. Continuous stall current remains 1.6 A for drive sizing, and the 23-bit incremental encoder means this axis still needs a homing move at startup despite the brake holding mechanical position. Maximum mechanical speed is rated to 6000 rpm, double the 3000 rpm nominal speed used above, leaving margin for brief overspeed during deceleration moves. IP67 sealing and the shared two-connector power/feedback interface mean this braked 200 W motor uses the same cabling and enclosure design as the rest of the 60 mm-flange Easy Lexium 18 BCH18 motors.
