The nominal output power is 3860 W at 400 V and 3660 W at 480 V, so the motor is optimized for the 400 V line. Peak stall torque reaches 60.1 N.m across the 115...480 V three-phase range, giving a healthy overload margin for acceleration transients. Continuous stall torque is 19.5 N.m over the same voltage window. ## Encoder and feedback for absolute position The absolute multiturn SinCos Hiperface encoder retains position through power cycles — no homing routine needed after a restart. The SinCos analog tracks provide fine interpolation for low-speed smoothness, while the Hiperface protocol carries the multiturn count over the serial link. Back EMF constant is 101 V/krpm at 20 °C, which sets the voltage-speed limit for the drive — at 3000 rpm the back EMF is about 303 V, leaving headroom for current regulation on a 400 VDC bus. ## Mounting, cooling, and environmental seals The 140 mm international standard flange (IEC 60034-7) with a 5.1 in (130 mm) centring collar and 0.4 in (11 mm) mounting holes fits standard servo motor footprints. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length. IP65 on the motor body and shaft bushing, IP67 on the housing — the motor withstands washdown spray but not submersion at the shaft seal. Natural convection cooling means no fan noise or filter maintenance, but the thermal budget depends on mounting surface and ambient airflow. ## Electrical parameters for drive tuning Stator resistance is 0.6 Ohm and inductance is 3.855 mH — these set the electrical time constant (~6.4 ms) and influence the current loop gains in the drive. Maximum continuous current is 44.1 A RMS, with the same value for 3-second peak, so the drive must supply that peak without saturation. Torque constant is 1.47 N.m/A at 120 °C copper temperature — derate from the cold value by about 8-10% as the winding heats to the 130 °C hot-spot limit.","metaTitle":"Schneider Electric SH31402P12A1200 Servo Motor, 3900 W","metaDescription":"Schneider Electric SH31402P12A1200 SH3 servo motor, 3900 W continuous power, 140 mm flange, IP65/IP67, absolute multiturn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31402P12A1200","Length":"10.7 in (272.5 mm)","Inertia":"0.0 kg.cm² of brake 12.68 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 140mm, 2 stacks, keyed Shaft, SinCos Multiturn 128, no Brake, straight, IP65/67","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"12.68 kg.cm²","Nominal torque":"164.6 lbf.in (18.6 N.m) 115 V single phase 151.3 lbf.in (17.1 N.m) 230 V single phase 108.9 lbf.in (12.3 N.m) 400 V three phase 85.9 lbf.in (9.7 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.47 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"3900 W","Mounting Support":"International standard flange","Sizing reference":"SH31402P","Back emf constant":"101 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"531.9 lbf.in (60.1 N.m) 115...480 V three phase","Stator inductance":"3.855 mH","Stator resistance":"0.6 Ohm","Maximum current Irms":"44.1 A","Nominal output power":"1460 W 115 V single phase 2690 W 230 V single phase 3860 W 400 V three phase 3660 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"5","Maximum axial force Fa":"300 N","Output current 3s peak":"44.1 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"172.6 lbf.in (19.5 N.m) 115...480 V three phase","IP degree of protection":"IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5 IP67 housing: conforming to IEC 60034-5","Maximum radial force Fr":"2240 N 1000 rpm 1780 N 2000 rpm 1550 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"13.2 A","Maximum mechanical speed":"4000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6a556e6f85ada54b80a04cbded7cfc6b.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH31402P12A1200/sh3-servomotor-140mm-2-stacks-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What is the nominal torque of SH31402P12A1200 at 400 V three-phase?","answer":"At 400 V three-phase the nominal torque is 12.3 N.m (108.9 lbf.in) at 3000 rpm.
