Where this motor drops on the line
The BEH18MR5513CF6D: The Lexium 18 BEH18 servo motor with brake sits in the mid-power slot of the Schneider servo range, sized for machine axes that need a holding brake for vertical or suspended loads. Continuous output is 5500 W at 380 V three-phase, with a nominal torque of 35 N.m at 1500 rpm and a peak stall torque of 87.5 N.m at 380 V — so the motor can accelerate well above its continuous rating for short index moves before falling back to the continuous figure. An Asian-standard 180 mm flange with four mounting holes lets it bolt into the common machine footprint used across Asian-built packaging, converting, and material-handling skids. The IP67 rating on the housing means the motor body and connector face tolerate washdown and dust exposure typical of food, beverage, and outdoor cell builds — but the cable gland and mated connector are the real wet-end seal, not the housing alone.
Torque, speed, and the brake that holds the load
Continuous stall torque is 35 N.m at 380 V three-phase, with a continuous stall current of 19.77 A — these are the figures that govern the constant-load region of the torque/speed curve, not the headline 5500 W. Maximum mechanical speed is 3000 rpm, so any application running the motor above that requires a different model from the family. Holding torque from the integrated brake is 50 N.m, which is what keeps a vertical axis from drifting when the drive disables output.
Feedback and electrical constants
Position feedback is a 23-bit optical multi-turn encoder, so the drive gets absolute multi-turn position back from the motor — no homing cycle after a power loss, and no battery-backed encoder add-on. The torque constant of 1.77 N.m/A at 40 °C and back-EMF constant of 121.39 V/krpm at 40 °C let the integrator pre-compute the current command for a given torque demand and the no-load speed ceiling at a given bus voltage. Stator resistance is 0.191 Ohm — small, which means copper losses are modest at the continuous rating. The motor is air-cooled and ten-pole, with parallel-key shaft end (12.0 mm key width on a 42.0 mm shaft, 113.0 mm shaft length) and no second shaft end. Two male/female connectors carry power and feedback separately, matching the Lexium 18 drive-side cabling — confirm the drive generation in the panel before pulling a spare, since the connector keying has changed across Lexium revisions.
