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.
Stepping up to a 60 mm flange, the Schneider Electric BCH18MD01332A5C still delivers 100 W and 0.32 N·m continuous stall torque, drawing 1.1 A continuous stall current. This brakeless, medium-inertia (0.16 kg.cm²) variant uses a 23-bit incremental encoder and suits horizontal axes where an external brake or self-locking mechanism already holds position when the drive is de-energized.
The 60 mm flange on the BCH18MD01332A5C carries the same 100 W, 0.32 N·m rating as the 40 mm-flange frame but with a larger medium-inertia rotor (0.16 kg.cm²) and a 254 N maximum radial force rating, so it tolerates more side-load from belt or pulley couplings than the smaller-flange motors. No brake is fitted, which keeps weight at 0.65 kg; pick the braked BCH18MD01332F5C instead if the axis needs to hold position without drive power. Size the Lexium 18 (LXM18) drive's continuous current to the 1.1 A continuous stall current and leave margin to the 3.4 A maximum permanent current for accelerating moves. The 23-bit incremental encoder means the controller must run a homing routine at startup or after any uncommanded stop. 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 two-connector male/female power and feedback interface match the rest of the Easy Lexium 18 BCH18 range, so this motor shares cabling and enclosure design with the smaller 40 mm-flange frame.
