850 W, 5.39 Nm — load matching and drive sizing
The BEH18MM0813CA6C: This Lexium 18 servo motor delivers 850 W continuous output power at 220 V single-phase, with a nominal torque of 5.39 N.m. The peak stall torque hits 16.17 N.m at 220 V — that's the short-duration overload headroom for acceleration or load transients. The continuous stall current is 6 A, while the maximum permanent current is 18 A at the same voltage and power. That tells you the drive needs to supply at least 18 A peak to exploit the motor's full torque capability.
23-bit encoder — positioning precision
The feedback is a 23-bit optic multi-turn encoder, giving 8,388,608 points per revolution. That's about 0.15 arc-seconds per count — enough for sub-arc-minute positioning in a direct-drive or low-ratio gearbox application. The optic encoder is a sealed unit inside the IP67 housing, so it holds accuracy even in washdown environments.
IP67 — washdown-ready without the brake
IP67 protection means the motor body and connector seal survive hose-down cleaning and airborne dust. This is the version without a holding brake — so if your vertical axis needs to hold position at power-off, you'll need to add an external brake or pair it with a drive that supports a holding brake output. The shaft is a parallel key with a 22 mm diameter and 58 mm key length, and the motor flange is the Asian standard 130 mm with four mounting holes. Cooling is air-cooled, so confirm the ambient airflow in the cabinet. Maximum radial force on the shaft is 686 N, axial force 196 N — stay within those to avoid bearing overload, especially with belt-driven loads.
