The BMI0703P31F is the three-phase servo motor from Schneider's BMI series, sized for 900 W nominal output on 400 V three-phase and 3.4 Nm continuous stall torque across the 208-480 V range. It includes an integrated EMC filter, an absolute single-turn SinCos Hiperface feedback encoder, and a 3 Nm holding brake. IP65 and natural convection cooling suit washdown and fanless installations. The motor's back EMF constant is 95.39 V/krpm, and torque constant 1.41 Nm/A, both measured at 68 °F (20 °C). Stator resistance is 7.99 ohm with inductance 25.6 mH, giving predictable torque linearity for current loop tuning.
