4.4 kW, 28.4 N.m — load-matching and torque delivery
The BEH18MR4413CA6D is a Lexium 18 servo motor from Schneider Electric, delivering 4.4 kW continuous output power at 380 V three-phase supply. Its nominal torque of 28.4 N.m at 1500 rpm sets the continuous-duty load point for sizing the driven axis — a conveyor, spindle, or rotary table that stays within this torque-speed envelope runs without thermal overload. Peak stall torque reaches 71 N.m at 380 V, giving headroom for acceleration transients or short-duration overloads. The 23-bit optic multi-turn encoder provides absolute position feedback, so the drive knows the rotor angle at power-up without a homing cycle — useful on machines where lost-position recovery time matters.
IP67 enclosure and Asian standard flange — integration constraints
Rated IP67, the motor body and connector interface withstand washdown environments — food-and-beverage lines or outdoor conveyor sections where hose-down cleaning is routine. The Asian standard flange (180 mm square, four mounting holes) matches common machine-frame patterns in Asian-built equipment; verify the bolt pattern against your gearbox or mounting plate before committing the BOM line. No holding brake is fitted on this variant (: Without). For vertical-axis applications or any axis that must hold position with power off, an external brake or a motor with an integrated brake is required. The shaft is a parallel key type, 35 mm diameter, 79 mm shaft length — standard for coupling to a gearbox or pulley.
Current draw, inertia, and drive sizing
The torque constant of 1.821 N.m/A at 40 °C lets the drive calculate the torque output from the current feedback — useful for tension control or force-limited moves. Back EMF constant is 125.24 V/krpm at 40 °C, which sets the voltage the motor generates when spun above rated speed; the drive's DC bus must stay above this back-EMF voltage to maintain current control at high rpm.
