11.5 N.m at 1500 rpm — the sizing anchor for this servo
The BEH18MM1813MF6C is a 1800 W servo motor from the Lexium 18 family, delivering 11.5 N.m nominal torque at 1500 rpm on a 220 V three-phase supply. That torque figure is the one you size the drive and the load coupling against — it's the continuous rating at the rated speed, not a peak number that disappears after a few seconds. The integrated 16 N.m holding brake holds vertical-axis loads without an external brake resistor or separate power supply — a line-down spare that saves panel space and wiring time on a replacement swap.
17-bit absolute encoder — no battery, no homing cycle
The magnetic multi-turn encoder gives 131072 points per turn with absolute position retention across power cycles. No backup battery needed, so on a packaging line where the motor gets swapped during a shift change, the replacement comes up knowing where the axis is — no re-referencing the home sensor. The 10-pole rotor design gives higher torque density than an 8-pole equivalent at the same frame size — the 34.5 N.m peak stall torque is 3x the continuous rating, enough for aggressive acceleration profiles on indexing conveyors.
IP67 and the 130 mm Asian flange — washdown-ready, common footprint
The parallel key shaft end with 22 mm diameter and 58 mm shaft length mates to standard timing-pulley or coupling bores — no custom machining on a replacement motor.
Active production — no lifecycle worry on this BOM line
The 12.5 A continuous stall current and 36 A peak current are the numbers the drive needs to see for proper sizing — the drive's continuous rating must cover 12.5 A, and its peak rating must handle 36 A for the acceleration duty cycle.
