Its speed-torque envelope is voltage-dependent: at 400 V three-phase, nominal speed is 3000 rpm with 12.9 N.m nominal torque; at 480 V three-phase, speed rises to 3600 rpm but torque drops to 9.1 N.m. The continuous stall torque across the 115...480 V three-phase range is 27.8 N.m, with a peak stall torque of 90.2 N.m — the margin for acceleration and overload is roughly 3.2× the continuous stall figure. ## Feedback and integration constraints The encoder is an absolute multiturn SinCos Hiperface — a single-cable feedback system that transmits position and commutation data over a hybrid power/signal cable. The Hiperface protocol is standard on Schneider Lexium drives; if the drive side expects EnDat or BiSS, a converter or different motor variant is needed. The electrical connection is a straight connector — no right-angle or rotatable option. This forces a minimum bend radius in the cable routing; plan at least 4× the cable diameter clearance behind the motor. The IP65 rating applies to the motor body, shaft bushing, and housing per IEC 60034-5, so the connector interface is sealed when mated, but the cable entry into the connector is the wet-end boundary — a gland or sealed cordset is required to maintain the rating. Mounting is via an international standard flange, size 140 mm (5.5 in), with a centring collar of 130 mm diameter and 3.5 mm depth. The four mounting holes are 11 mm diameter on a bolt circle that matches the IEC 72-1 frame standard for 140 mm flange. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, 8 mm key width — this is a standard metric shaft dimension, compatible with most off-the-shelf couplings and pulleys for that bore size. ## Sourcing and lifecycle — active, quoted to order The stator resistance is 0.4 Ω and inductance is 2.66 mH — these values set the electrical time constant (~6.7 ms) and influence the current-loop tuning on the drive. 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. These are the numbers the drive's autotuning routine uses to calculate the motor model; if the drive does not have a preloaded SH3 motor profile, these parameters must be entered manually. Maximum RMS current is 61.0 A, with a 3-second peak current also 61.0 A — this is a high-current, low-impedance winding designed for high acceleration torque. The radial force limits are 2420 N at 1000 rpm, 1920 N at 2000 rpm, and 1670 N at 3000 rpm; the axial force limit is 300 N. These bearing load ratings must be respected when sizing the coupling and belt tension to avoid premature bearing failure.","metaTitle":"Schneider Electric SH31403P12A1200 Servo Motor, 4.1 kW","metaDescription":"Schneider Electric SH31403P12A1200 SH3 servo motor, 4.1 kW continuous, 3000 rpm at 400 V three-phase, absolute multiturn SinCos Hiperface encoder, IP65, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31403P12A1200","Length":"12.9 in (327.5 mm)","Inertia":"0.0 kg.cm² of brake 17.94 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 140mm, 3 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":"17.94 kg.cm²","Nominal torque":"218.6 lbf.in (24.7 N.m) 115 V single phase 187.6 lbf.in (21.2 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 80.5 lbf.in (9.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.58 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4100 W","Mounting Support":"International standard flange","Sizing reference":"SH31403P","Back emf constant":"105 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"798.3 lbf.in (90.2 N.m) 115...480 V three phase","Stator inductance":"2.66 mH","Stator resistance":"0.4 Ohm","Maximum current Irms":"61.0 A","Nominal output power":"1940 W 115 V single phase 3330 W 230 V single phase 4050 W 400 V three phase 3430 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":"61.0 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"246.05 lbf.in (27.8 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":"2420 N 1000 rpm 1920 N 2000 rpm 1670 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"17.6 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/3baba90d3edff3f8b9e092741685317c.pdf","sourceUrl":"https://www.se.com/nl/en/product/SH31403P12A1200/sh3-servomotor-140mm-3-stacks-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What encoder type does the SH31403P12A1200 use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder.
