It is built for applications that need sustained torque at speed — think indexing tables, rotary knives, or winder drives where the load profile demands both peak and continuous output. Nominal torque lands at 30.2 N.m on 400 V three-phase, with a continuous stall torque of 33.4 N.m across the 115...480 V three-phase range. The peak stall torque hits 131.9 N.m — enough to break through a jam or accelerate a high-inertia load without tripping the drive on overcurrent. ## Absolute multiturn Hiperface encoder and IP65/IP67 sealing The absolute multiturn SinCos Hiperface encoder gives position feedback without a home cycle after power loss — the drive knows the shaft angle and the number of turns since commissioning. This matters on a gantry or rotary axis where a homing move would crash the tool into the part. IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5. The shaft bushing seal is the wet-end barrier — if the machine sees washdown or coolant splash, this motor survives where an IP54 unit would wick moisture into the bearings. The straight connector exits the motor body without a right-angle joint, so the cable gland sees less bending stress in a fixed installation. ## Smooth shaft, no brake — coupling and holding strategy The shaft is smooth with a 24 mm diameter and 50 mm length. No keyway means the coupling must transmit torque through a friction fit or a clamping hub — a set-screw coupling on a smooth shaft will slip under the 131.9 N.m peak torque; use a clamping or shrink-disc coupling rated for the full peak torque plus a safety factor. ## Current ratings and thermal limits for drive and cable sizing Continuous stall current is 21.3 A; the maximum peak current (3 s) is 95.6 A. The drive's continuous output rating must be ≥ 21.3 A, and the peak current capability must handle 95.6 A for at least 3 seconds. Cable cross-section should be sized for 21.3 A continuous with a derating factor for the motor's 130 °C copper hot temperature and the cable routing in the cable track. Stator resistance is 0.28 Ohm and inductance is 2.035 mH — these set the I²R copper loss and the current ripple at the drive's PWM carrier frequency. The torque constant is 1.57 N.m/A at 120 °C, and the back EMF constant is 104 V/krpm at 20 °C. Enter these into the drive autotune routine, not the default motor parameters, or the current loop bandwidth will be wrong and the motor will run rough at low speed.","metaTitle":"Schneider SH31404P02A1200 Servo Motor, 4040 W, 140 mm Flange","metaDescription":"Schneider Electric SH31404P02A1200 SH3 servo motor, 4040 W continuous power, 30.2 N.m nominal torque at 400 V three-phase, IP65/IP67, absolute multiturn","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31404P02A1200","Length":"15.06 in (382.5 mm)","Inertia":"0.0 kg.cm² of brake 23.7 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 140mm, 4 stacks, smooth 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":"23.7 kg.cm²","Nominal torque":"267.3 lbf.in (30.2 N.m) 115 V single phase 232.8 lbf.in (26.3 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 98.2 lbf.in (11.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.57 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4040 W","Mounting Support":"International standard flange","Sizing reference":"SH31404P","Back emf constant":"104 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"1167.4 lbf.in (131.9 N.m) 115...480 V three phase","Stator inductance":"2.035 mH","Stator resistance":"0.28 Ohm","Maximum current Irms":"95.6 A","Nominal output power":"2370 W 115 V single phase 4130 W 230 V single phase 4040 W 400 V three phase 4190 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":"95.6 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"295.6 lbf.in (33.4 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":"2660 N 1000 rpm 2110 N 2000 rpm 1840 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"21.3 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/81e4e4a7033d9f47f856b8ed21602763.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31404P02A1200/sh3-servomotor-140mm-4-stacks-smooth-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What encoder type does the SH31404P02A1200 use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder, which provides position and speed feedback without needing a homing cycle after power loss."},{"question":"What are the IP ratings for this servo motor?","answer":"IP65 on the motor body and shaft bushing, IP67 on the housing, conforming to IEC 60034-5.
