The shaft is a smooth 0.9 in (24 mm) diameter, 2.0 in (50 mm) long, with no keyway or flat — a clamping-type coupling or shrink-fit pulley is required for torque transmission. Overall body length is 10.7 in (272.5 mm), and the centring collar depth is 0.1 in (3.5 mm) — these dimensions define the envelope for enclosure fit and shaft coupling clearance. The electrical connection is via a straight connector, so the mating cable connector must be oriented axially, not at an angle. ## Electrical ratings — speed, torque, and power by supply voltage This is a three-phase servo motor with 5 poles, and its nominal speed and torque depend on the supply voltage: at 115 V single phase it delivers 750 rpm and 164.6 lbf.in (18.6 N.m); at 230 V single phase, 1500 rpm and 151.3 lbf.in (17.1 N.m); at 400 V three phase, 3000 rpm and 108.9 lbf.in (12.3 N.m); and at 480 V three phase, 3600 rpm and 85.9 lbf.in (9.7 N.m). Continuous power is 3900 W, with nominal output power varying by supply: 1460 W at 115 V single phase, 2690 W at 230 V single phase, 3860 W at 400 V three phase, and 3660 W at 480 V three phase. The continuous stall torque is 172.6 lbf.in (19.5 N.m) across the 115...480 V three-phase range, with a continuous stall current of 13.2 A — this is the torque the motor can sustain indefinitely without exceeding the 266 °F (130 °C) copper hot temperature limit. Peak stall torque is 531.9 lbf.in (60.1 N.m) at 115...480 V three phase, with a maximum current Irms of 44.1 A — this short-duration torque is available for acceleration and deceleration, limited by the drive's peak current capability. Maximum mechanical speed is 4000 rpm — the absolute speed limit beyond which mechanical damage may occur, regardless of supply voltage. ## Feedback, cooling, and environmental protection The encoder is an absolute single-turn SinCos Hiperface type — this provides position feedback at power-up without a homing sequence, and the SinCos interface is compatible with Schneider and third-party servo drives that support the Hiperface protocol. Cooling is by natural convection — no fan or forced air is required, but the motor must be mounted with adequate airflow around the housing to dissipate heat, especially at continuous rated torque. The motor and shaft bushing are rated IP65 per IEC 60034-5, meaning the housing is dust-tight and protected against water jets from any direction — suitable for washdown environments, but the mating connector must also be IP-rated to maintain the seal. The motor ships as a single unit (1 per package) without a holding brake — if the application requires a brake for vertical-axis holding or power-off safety, an external brake must be added to the system.","metaTitle":"Schneider Electric SH31402P01A1100 SH3 Servo Motor, 3900 W","metaDescription":"Schneider Electric SH31402P01A1100 SH3 servo motor, 3900 W continuous, 140 mm flange, IP65, absolute SinCos Hiperface encoder, smooth shaft.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.7 in (272.5 mm)","Shaft end":"Smooth shaft","Encoder type":"Absolute single turn 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":"11.225 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","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","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/448c61bd0afbb417617cc560c630cdb8.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31402P01A1100/sh3-servomotor-140mm-2-stacks-smooth-shaft-sincos-singleturn-128-no-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31402P01A1100/alternatives.json"},"ai":{"faq":[{"question":"What is the torque constant and back EMF constant of SH31402P01A1100?","answer":"The torque constant is 1.47 N.m/A at 248 °F (120 °C), and the back EMF constant is 101 V/krpm at 68 °F (20 °C).
