At 400 V three-phase, nominal speed is 3000 rpm with 108.9 lbf·in (12.3 N·m) of torque. Plug it into 480 V three-phase and the speed climbs to 3600 rpm, but torque drops to 85.9 lbf·in (9.7 N·m). Continuous power output stays close across the three-phase range: 3860 W at 400 V, 3660 W at 480 V. The continuous stall torque is 172.6 lbf·in (19.5 N·m) regardless of three-phase voltage, with a continuous stall current of 13.2 A. Peak stall torque hits 531.9 lbf·in (60.1 N·m), useful for short-duration acceleration or overcoming static friction. ## Encoder, feedback, and integration fit The absolute single-turn SinCos Hiperface encoder gives position feedback on power-up without a homing routine — the controller reads the shaft angle directly. This cuts commissioning time on multi-axis machines where each axis would otherwise need a reference move. No holding brake is fitted on this variant. If the load must hold position with power off, a separate brake resistor or external holding brake on the axis is needed. The smooth shaft (no keyway) means the coupling or pulley is secured by a clamping mechanism — confirm the shaft diameter of 24 mm and length of 50 mm match the mating hub. IP65 on the motor body and shaft bushing, IP67 on the housing. ## Electrical parameters for drive tuning Back EMF constant is 101 V/krpm at 20 °C, and the torque constant is 1.47 N·m/A at 120 °C copper temperature. The maximum continuous current is 44.1 A — the drive must be sized to deliver this without saturating the power stage.","metaTitle":"Schneider SH31402P01A1200 Servo Motor, 3-phase, 3900 W","metaDescription":"Schneider Electric SH31402P01A1200 SH3 servo motor, 3-phase, 3900 W continuous, 3000 rpm at 400 V.
