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.
The Schneider Electric BCH18MF07332F5C is a 750 W Easy Lexium 18 BCH18 servo motor rated for 2.39 N·m continuous stall torque at 3000 rpm nominal speed, with a 6000 rpm maximum mechanical speed. Built on an 80 mm flange for LXM18 drive pairing, it carries a 23-bit optic incremental encoder and an integrated 3.0 N·m holding brake for position retention when the drive is de-energized.
Pick the BCH18MF07332F5C when the application needs the smallest Easy Lexium 18 motor that still comes with a holding brake — its 3.0 N·m brake torque exceeds the motor's own 2.39 N·m stall torque, so a vertical or gravity-loaded axis stays put the instant the LXM18 drive is disabled. The 23-bit optic incremental encoder has no absolute-position memory, so the axis must re-home after every power-up; choose a multi-turn (OPTO MT) sibling instead if the machine needs to resume mid-cycle without a homing move. Within the 80 mm M80 flange, the 1 kW BCH18MF10332A5C and BCH18MF10332F5C step up to more torque and power at the same flange size and shaft dimensions, for machines that outgrow the 750 W rating without changing the mechanical envelope.
