The SH31401P12F1000 is a three-phase servo motor whose nominal speed depends on the supply voltage: 750 rpm at 115 V single phase, 1500 rpm at 230 V single phase, 3000 rpm at 400 V three phase, and 3600 rpm at 480 V three phase. That means the same motor covers a wide speed range, but the torque available at each speed also shifts — nominal torque drops from 10.95 N.m at 115 V to 8.4 N.m at 480 V three phase. Continuous power is 2900 W, with peak stall torque reaching 27 N.m for short-term acceleration. The holding brake delivers 23 N.m, which holds a vertical load without power — no external brake resistor needed for static holding. ## Encoder feedback and position loop The absolute multiturn SinCos Hiperface encoder gives position feedback without a homing sequence on power-up — the drive knows the rotor position immediately. This is critical for applications where the machine must resume operation after a power cycle without referencing. ## Mounting and environmental sealing The motor mounts on an international standard flange with a 140 mm flange size and a centring collar diameter of 130 mm. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length. IP54 is standard with the shaft bushing without seal ring; upgrading to the IP65 shaft bushing gives washdown protection per IEC 60034-5. Maximum radial force at the shaft is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm. Maximum axial force is 300 N. These limits govern bearing life in overhung-load applications like belt drives. ## Electrical parameters and drive matching Stator resistance is 1.41 Ohm and inductance is 23.72 mH. The torque constant is 1.43 N.m/A at 120 °C copper temperature, and the back EMF constant is 100 V/krpm at 20 °C. Maximum continuous stall current is 7.8 A, and the maximum RMS current is 20.8 A — the drive must supply this peak current for acceleration. Continuous stall torque is 11.1 N.m across the 115–480 V three-phase range, with the holding brake torque at 23 N.m. The brake is sized for static holding, not dynamic stopping — use the drive's dynamic braking resistor for deceleration.","metaTitle":"Schneider Electric SH31401P12F1000 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401P12F1000 servo motor with brake, 3-phase, 2.9 kW continuous, 23 N.m holding torque.
