The nominal speed scales with the supply voltage — the torque available drops as speed increases, which is typical for a constant-power region above base speed. Peak stall torque reaches 90.2 N.m across the 115–480 V three-phase range, giving a 3.3× overload margin over the 400 V nominal torque for acceleration and emergency stops. ## Holding brake and mechanical interface Mounting uses an international standard 140 mm flange with a 24 mm shaft diameter and parallel key. The centring collar depth is 3.5 mm, and the four mounting holes are 11 mm diameter on the flange face. ## Encoder feedback and environmental sealing The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the drive reads the absolute position from the encoder's multiturn count. This eliminates the need for a reference run after a power loss or emergency stop. IP65 on the motor body and shaft bushing, IP67 on the housing — the motor withstands washdown and hose-directed water per IEC 60034-5. The straight connector exits the motor body; cable routing must allow the connector to remain sealed at the mating point. ## Electrical parameters for drive matching Stator resistance is 0.4 Ω and inductance is 2.66 mH — these set the electrical time constant and influence the drive's current-loop tuning. The torque constant is 1.58 N.m/A at 120 °C copper temperature, and the back EMF constant is 105 V/krpm at 20 °C. Maximum continuous current is 61.0 A RMS, with the same value for the 3-second peak current. The drive must be sized to supply this peak current for acceleration and deceleration without tripping on overcurrent. ## Sourcing and lifecycle — active production The SH31403P sizing reference identifies the motor frame and winding variant. For volume procurement, the full order code SH31403P12F1200 must match the drive and cable part numbers in the BOM to ensure the connector and feedback interface align.","metaTitle":"Schneider Electric SH31403P12F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31403P12F1200 servo motor with holding brake, 4.1 kW continuous power, 140 mm flange, IP65/IP67.
