1.8 kW at 1500 rpm — what the torque curve means for your axis
The BEH18MM1813CA6D delivers 11.5 N.m nominal torque and 1.8 kW continuous power at 380 V three-phase, 1500 rpm. That torque constant of 1.636 N.m/A at 40 °C means the drive needs to supply about 7 A continuous stall current to hold position — the maximum permanent current is 21.09 A, which supports the 34.5 N.m peak stall torque for acceleration transients. The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution absolute position feedback — no homing cycle needed after power loss. This matters for applications where the axis must resume from the last commanded position without a reference move.
IP67 and Asian standard flange — mounting constraints
IP67 protection means the motor body withstands washdown — the shaft seal and connector interface are rated for hose-directed water. This suits food-and-bev or washdown conveyor lines where the motor is in the splash zone. The Asian standard flange (130 mm flange size, 4 mounting holes) matches the common Japanese/Taiwanese machine-tool interface — confirm your gearbox or mounting bracket uses the same bolt pattern before committing. The shaft is 22 mm diameter with a 58 mm parallel key (8 mm key width). Maximum radial force is 686 N, maximum axial force 196 N — stay within these limits for belt-drive or direct-coupling applications to avoid bearing overload. Overall dimensions: 168.6 mm width, 174.5 mm depth, 130 mm height. The 168.6 mm square body fits standard NEMA 56C frame footprints with adapter plates — verify the bolt-hole circle matches your existing mount.
Sourcing — current lifecycle, quoted to order
The motor uses two connectors (male/female) for power and feedback — the 23-bit encoder is a digital interface, likely Hiperface DSL or similar single-cable protocol. Confirm the mating connector part numbers and cable length with the drive specification before ordering.
