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.
Rated for 1 kW continuous output, the Schneider Electric BCH18MF10332A5C is an Easy Lexium 18 BCH18 servo motor delivering 3.18 N·m continuous stall torque at 3000 rpm nominal speed, with a 6000 rpm maximum mechanical speed. It ships on the same 80 mm flange as the lower-power BCH18MF07332F5C but without a holding brake, and carries a 23-bit optic incremental encoder for position feedback to an LXM18 drive.
Choose the BCH18MF10332A5C for an 80 mm M80 axis that does not need to hold position once the LXM18 drive is de-energized — skipping the brake keeps the motor shorter and lighter than its braked sibling, the BCH18MF10332F5C, for the same 1 kW rating and 3.18 N·m continuous stall torque. Its 23-bit optic incremental encoder requires a homing routine after each power cycle, since it has no memory of absolute position; the BCH18MF1033CF5C carries the same power and torque with a multi-turn encoder for machines that must resume without re-homing. At 22.8 A maximum permanent current, size the LXM18 drive's output stage to that figure rather than the 6.5 A continuous stall current, and note the 6000 rpm maximum mechanical speed ceiling if the application ever needs to run faster than the 3000 rpm nominal point.
