Form factor: what lands in the panel
The BEH18MR5513MF6D: An IP67 rating on the motor body means the housing tolerates temporary immersion and washdown — practical for food-and-beverment lines, machine-tool cells with coolant splash, or any deployment where the driven mechanism sits below the panel enclosure rather than inside it.
Headline ratings: 5.5 kW at 380 V three-phase
Continuous output power is 5500 W at 380 V three-phase, with a nominal torque of 35 N.m and a nominal speed of 1500 rpm under the same voltage. Continuous stall torque holds at 35 N.m drawing 19.77 A; peak stall torque reaches 87.5 N.m at 380 V — meaning the drive can deliver roughly 2.5× the rated torque for short acceleration ramps before tripping the drive current limit. The electrical signature sets the drive commissioning baseline: a torque constant of 1.77 N.m/A at 40 °C, back-EMF constant of 121.39 V/krpm at 40 °C, and stator resistance of 0.191 Ω. Maximum mechanical speed is rated 3000 rpm, and maximum RMS current reaches 45.08 A at 5.5 kW, 380 V — the sizing number for the upstream drive and cabling rather than the continuous-duty number.
Feedback, poles, and the holding brake
The motor carries an integrated holding brake rated 50 N.m — well above the 35 N.m continuous torque, so the brake holds the load stationary with margin after the drive enable is removed. Power connection is via a two-connector male/female pair, which on this family is the standard pre-wired feedback + power harness interface rather than a terminal box.
Mechanical envelope: radial, axial, and the gearbox side
Maximum radial load on the shaft is 1764 N and maximum axial load 588 N — the figures that decide whether the motor drives its load directly through a coupling, or through a right-angle gearbox that absorbs the overhung load. Cooling is air-cooled with no second shaft end, so the layout has a clean cable exit on one face and a single drive-end output.
