1.8 kW at 1500 rpm — torque and speed envelope
The BEH18MM1813MA6C: Rated for 1800 W continuous output at 220 V, three-phase supply, with a nominal speed of 1500 rpm. The nominal torque is 11.5 N.m at 220 V, and the continuous stall torque matches that figure — meaning the motor delivers full rated torque down to zero speed without derating, as long as the drive's current loop is tuned for the 12.5 A continuous stall current. Peak stall torque reaches 34.5 N.m at 220 V — roughly 3× the continuous rating — for acceleration and deceleration transients. The maximum mechanical speed is 3000 rpm, so the motor can overspeed 2:1 above nominal if the load inertia and drive bus voltage permit.
Encoder feedback and electrical interface
Fitted with a 17-bit magnetic multi-turn encoder (131,072 points per turn absolute position). The multi-turn count tracks absolute position over multiple shaft revolutions without a battery backup — useful for applications that must retain position after a power cycle, such as gantry axes or rotary indexing tables. Electrical connection uses two connectors (male/female), one for power and one for feedback. The motor has 10 poles, so the electrical frequency at 1500 rpm is 125 Hz — the drive's current regulator bandwidth must be set above this to avoid torque ripple at low speed. Torque constant is 0.92 N.m/A at 40 °C, and the back EMF constant is 63.35 V/krpm at 40 °C. Use these to calculate the required drive current for a given torque target and to verify the DC bus voltage headroom at maximum speed — at 3000 rpm the back EMF reaches ~190 V line-to-line, leaving 30 V headroom on a 220 V bus for current regulation.
Mechanical fit and environmental rating
Asian standard flange with a 130 mm flange size and four 9 mm mounting holes on a bolt circle matching the standard. The shaft is 22 mm diameter with a parallel key, 58 mm shaft length — confirm the coupling bore and keyway dimensions before assembly. Overall body dimensions: 168.6 mm width, 174.5 mm depth, 130 mm height. IP67 protection rating means the motor body and shaft seal withstand immersion up to 1 m depth for 30 minutes — suitable for washdown environments in food processing or outdoor installations where hose-down cleaning is routine. No holding brake is fitted; if the vertical load must be held at power-off, an external brake or a brake-equipped variant is needed. Maximum radial force Fr is 686 N and maximum axial force Fa is 196 N — these are the bearing load limits at the shaft centre. Overhung loads from belt drives or direct couplings must stay within these figures to avoid premature bearing failure.
The motor belongs to the Lexium 18 family, which is Schneider's compact servo motor range for general-purpose motion control. The 1.8 kW power class and 130 mm flange size place it in the mid-range of the family, suitable for applications like packaging, material handling, and converting lines.
