23-bit optic multi-turn encoder — positioning resolution
The BEH18LH1033CA6D carries a 23-bit optic multi-turn encoder, giving 8,388,608 counts per revolution. That resolution feeds the velocity loop with position data clean enough to hold tight following error on a pick-and-place gantry or a rotary indexing station. The optic encoder type means the feedback is immune to magnetic interference from adjacent motor windings or drive cables — a real advantage in a crowded cabinet where resolver or magnetic encoder signals can pick up noise.
Torque and power — 3.18 N.m at 1000 W
Rated 3.18 N.m nominal torque at 380 V three-phase, with a continuous power of 1000 W. The torque constant is 0.924 N.m/A at 40 °C, so the current-to-torque relationship is linear enough to tune the current loop without a lookup table. Continuous stall current is 3.44 A, and the maximum current is 10.32 A at 1 kW. The drive must be sized to supply that peak current without hitting its current limit during the acceleration phase.
IP67 and flange mounting — washdown-ready integration
IP67 protection means the motor body and shaft seal withstand direct water jets and dust ingress — suitable for food-and-bev lines, washdown stations, or outdoor conveyor sections where a standard IP54 motor would fail. The Asian standard flange has a 100 mm square face with four 9 mm mounting holes, and the shaft is a 24 mm diameter parallel key with 45 mm length. The flange pattern matches the common 100 mm frame size used across Lexium 18 motors, so swapping into an existing mounting plate is straightforward.
The Lexium 18 range is Schneider's compact servo family, positioned for applications needing moderate power density with high-resolution feedback.
