On 480 V three-phase it reaches 3600 rpm at 3.17 kW output. For single-phase 230 V supply, expect 1670 W at 1500 rpm; on 115 V single-phase, 860 W at 750 rpm. Nominal torque varies with supply: 10.95 N·m at 115 V single-phase, 10.6 N·m at 230 V single-phase, 9.2 N·m at 400 V three-phase, and 8.4 N·m at 480 V three-phase. Peak stall torque is 27 N·m across the 115–480 V three-phase range. Continuous stall torque is 11.1 N·m at 7.8 A continuous stall current. The torque constant is 1.43 N·m/A at 120 °C copper temperature. ## Feedback and mechanical fit Encoder is an absolute multiturn SinCos Hiperface type — no homing sequence needed on power-up, position is retained. The back EMF constant is 100 V/krpm at 20 °C. Motor flange is 140 mm (5.5 in) with an international standard flange mount. Shaft diameter is 24 mm with a parallel key, shaft length 50 mm. Centring collar diameter 130 mm, depth 3.5 mm. Four mounting holes at 11 mm diameter on the flange face. ## Environmental and mounting constraints IP rating depends on the shaft seal: IP54 with shaft bushing without seal ring, IP65 with shaft bushing seal fitted. Both conform to IEC 60034-5. Cooling is natural convection — no fan, so the motor relies on the mounting surface and ambient airflow for heat rejection. 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 coupling and pulley selection. Electrical connection is a straight connector — no right-angle adapter, so plan cable exit clearance accordingly. Stator resistance is 1.41 Ω, inductance 23.72 mH — these affect the drive's current loop tuning and PWM ripple.","metaTitle":"Schneider Electric SH31401P12A1000 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P12A1000 SH3 servo motor, 2.9 kW continuous power, 3000 rpm at 400 V three-phase.
