Frame, flange, and what the shaft drives
The BEH18LM5033CA6D: The BEH18 sits in the Lexium 18 servo family on a 130 mm flange — the four 9 mm mounting holes land on an Asian standard flange footprint, and the 28 mm parallel-key shaft with 63 mm of usable length plus an 8 mm key is sized to drive a gear reducer, timing-belt pulley, or a coupling directly without an intermediate bushing. Watch the loading envelope before sizing the coupling: the shaft tolerates up to 686 N radial and 196 N axial, so a heavy pinion or overhung belt that pushes past 686 N radial seating force will hammer the front bearing long before the motor reaches its torque ceiling. The body is air-cooled with an IP67 rating at the housing, which lets the unit sit inside a machine guard near a coolant splash zone without an additional shroud — but the cable glands are where water actually gets in, so the sealing on the two-connector lead set is the working limit, not the housing itself.
Torque, speed, and the 380 V envelope
At 380 V three-phase the BEH18 delivers 15.8 N·m of continuous torque at 3000 rpm — the 5000 W continuous power rating is the headline number, with a peak stall capability of 47.4 N·m during acceleration transients. Maximum mechanical speed caps at 3000 rpm; the 10-pole rotor and the 23-bit multi-turn optic encoder give the drive the position feedback resolution typical of this Lexium class for high-throughput point-to-point moves. Electrical scaling is clean — torque constant 0.942 N·m/A at 40 °C, back-EMF constant 67.43 V/krpm at 40 °C — so 16.77 A continuous stall current maps directly to the 15.8 N·m stall figure and the 50.31 A Irms peak lines up with the 47.4 N·m peak torque during a step move.
Options populated on this build
This build ships without a holding brake and without a second shaft end — a clean single-shaft configuration for a horizontally mounted coupling load, where the holding function is held by the drive's regen or by the downstream gearbox brake instead.
Lifecycle and what to expect when sourcing
Independent distribution sources this configuration to order: lead time, price, and quantity breaks are confirmed at RFQ against the BOM line, with manufacturer traceability on the shipment.
