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.
Moving to a larger 80 mm flange, the Schneider Electric BCH18MF02332A5C still outputs 200 W and 0.64 N·m continuous stall torque, but with a higher maximum radial force rating of 392 N than the 60 mm-flange 200 W motors. Continuous stall current is 1.6 A, no brake is fitted, and the 23-bit incremental encoder suits horizontal axes with external holding.
The 80 mm flange gives the BCH18MF02332A5C a 392 N maximum radial force and 147 N maximum axial force rating — well above the 254 N / 74 N figures on the 60 mm-flange 200 W motors — so it is the better fit when the axis sees significant belt or pulley side-load at the same 200 W, 0.64 N·m rating. No brake is fitted, suiting a horizontal axis with no drift risk; pick the braked BCH18MF02332F5C for a vertical load instead. Continuous stall current is 1.6 A for Lexium 18 (LXM18) drive sizing, and the 23-bit incremental encoder requires a homing routine at startup. Medium-inertia (0.55 kg.cm²) construction keeps it matched to load-heavy axes rather than fast point-to-point cycling. Maximum mechanical speed is rated to 6000 rpm against the 3000 rpm nominal speed used for the torque and current figures above, leaving margin for brief overspeed during deceleration. IP67 sealing and the shared two-connector power/feedback interface match the rest of the Easy Lexium 18 BCH18 range, so moving a 200 W axis from the 60 mm to the 80 mm flange does not change the cabling design.
