850 W servo with integrated holding brake
The BEH18MM0813CF6D is a Lexium 18 servo motor delivering 850 W continuous power at 1500 rpm nominal speed (380 V three-phase). The 16.0 N.m holding brake means this motor holds position on a vertical axis without a separate brake resistor or external mechanical lock — the brake engages when power is removed, so a Z-axis or gravity-loaded load stays put during a power loss or E-stop. The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution absolute position feedback — the motor knows its shaft angle even after a power cycle, so homing sequences on startup are unnecessary. This matters on a packaging or material-handling line where the machine must resume from the last known position after a shift change or power interruption.
Torque and thermal limits for the application
Nominal torque is 5.39 N.m at 380 V; peak stall torque reaches 16.17 N.m — the motor can deliver nearly 3× rated torque briefly for acceleration or overcoming static friction. The torque constant of 1.706 N.m/A at 40 °C means the drive must supply about 3.16 A continuous stall current to hold rated torque at standstill. IP67 rating means the motor body and shaft seal withstand washdown — suitable for food-and-beverage lines or wet machining environments where coolant spray is constant. The air-cooled design relies on natural convection; in a confined enclosure with multiple motors, check the ambient temperature stays below the motor's thermal limit at full load.
Mounting and mechanical interface
Asian standard flange, 130 mm square, with four mounting holes. The shaft is 22 mm diameter with a parallel key (key width 8.0 mm, shaft length 58.0 mm) — this is a standard metric keyed shaft for timing pulleys or coupling to a leadscrew. Maximum radial force is 686 N and maximum axial force is 196 N; belt-drive applications should keep belt tension within these limits to avoid bearing overload.
