5.5 kW continuous at 380 V — what that rating actually buys
BEH18MR5513MA6D sits in the Lexium 18 line (short name BEH18) and delivers 5500 W of continuous output power at 380 V three-phase, paired with a 35 N.m nominal torque at the same voltage — the continuous and nominal torque figures are identical here, meaning the motor is rated to hold 35 N.m indefinitely without slipping into thermal derating. That continuous rating matters more than the headline 5.5 kW for sizing: peak stall torque reaches 87.5 N.m at 380 V three-phase, with a maximum Irms of 45.08 A — so the drive must be sized to deliver peak current during accel/decel, while thermal design follows the 19.77 A continuous stall current.
Mechanical envelope — flange, shaft, and load limits
The motor mounts on an Asian standard flange (180 mm flange size) with four mounting holes, a parallel-key shaft with 12.0 mm key width and 113.0 mm shaft length, 42.0 mm shaft diameter — a heavy-duty output suited to packaging, converting and machine-tool spindles rather than tabletop automation. Mechanical ceiling is 3000.0 rpm, with maximum radial force Fr of 1764 N and maximum axial force Fa of 588 N — bearing-life calculations need to use these, not the electrical rating, when the coupling and pulley stack up against the shaft.
Feedback, cooling, and the IP67 rating
Feedback is a 17-bit magnetic multi-turn encoder — magnetic rather than optical, which is the typical Lexium 18 choice for harsh environments where dust, vibration and oil mist would shorten an optical disk's life. The motor is air-cooled (no water jacket), sealed to IP67, and wired through two connectors male/female — the IP67 figure means the body holds up to temporary immersion, which puts it in scope for food-and-bev washdown lines and outdoor skids, not just panel-room service. No holding brake is fitted; no second shaft end is provided.
Electrical constants for the drive commissioning sheet
Torque constant is 1.77 N.m/A at 40 °C, back-EMF constant 121.39 V/krpm at 40 °C, stator resistance 0.191 Ohm — drive auto-tune can read the nameplate and back-calculate, but the 40 °C reference matters: cold values look better than hot operating values, and the controller should bias the current loop toward the hot figure during thermal soak.
Lifecycle and sourcing posture
Lifecycle stage is recorded as current in the product record — no official end-of-life notice or successor order code on file from the manufacturer. As an independent distributor, the supply channel is quoted-to-order against the BOM from independent distribution; lead time, lot size and traceability documents are confirmed at RFQ.
