Its nominal torque and speed shift with the supply: at 400 V three-phase it produces 2.52 N.m at 2500 rpm, and at 480 V three-phase the same torque holds at 3000 rpm. On single-phase 230 V it drops to 2.71 N.m at 1250 rpm, and on 115 V single-phase to 2.8 N.m at 625 rpm — so the application voltage directly sets the usable speed-torque envelope. Peak stall torque reaches 9.6 N.m across the 115–480 V three-phase range, with a continuous stall torque of 2.94 N.m at 1.8 A continuous stall current. The maximum current Irms is 6.3 A, and the torque constant is 1.63 N.m/A at 120 °C copper temperature. These numbers define the acceleration ceiling and the thermal limit for continuous duty cycles. ## Encoder, feedback, and connection details This motor carries an absolute multiturn SinCos Hiperface encoder — the Hiperface protocol gives single-cable feedback for position and speed, with multiturn counts surviving power loss. The back EMF constant is 115 V/krpm at 20 °C, which sets the voltage the drive sees at speed. Electrical connection is via a rotatable right-angled connector or a straight connector — both options are listed, so the cable exit direction can be oriented to fit the cable tray or drag chain path. The motor is cooled by natural convection, so no forced-air clearance is needed around the housing. ## Mechanical interface and environmental sealing The motor flange is 100 mm (3.9 in) with an international standard flange pattern, centring collar diameter 95 mm and depth 3.5 mm, and four mounting holes at 9.0 mm diameter. The shaft is 19 mm diameter, 40 mm length, with a parallel key (6 mm key width) — a standard NEMA/metric interface for coupling to leadscrews, pulleys, or gearboxes.","metaTitle":"Schneider Electric SH31001M12A1200 Servo Motor, 660 W","metaDescription":"Schneider Electric SH31001M12A1200 SH3 servo motor, 660 W continuous power, 2.8 Nm nominal torque at 400 V three-phase, 3000 rpm, absolute multiturn SinCos","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"6.6 in (168.5 mm)","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"1.6 in (40 mm)","Holding brake":"Without","Nominal speed":"625 rpm 115 V single phase 1250 rpm 230 V single phase 2500 rpm 400 V three phase 3000 rpm 480 V three phase","Rotor inertia":"1.4 kg.cm²","Nominal torque":"24.8 lbf.in (2.8 N.m) 115 V single phase 23.99 lbf.in (2.71 N.m) 230 V single phase 22.30 lbf.in (2.52 N.m) 400 V three phase 22.30 lbf.in (2.52 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.63 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"660 W","Mounting Support":"International standard flange","Sizing reference":"SH31001M","Back emf constant":"115 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"85.0 lbf.in (9.6 N.m) 115...480 V three phase","Stator inductance":"99.15 mH","Stator resistance":"13.9 Ohm","Maximum current Irms":"6.3 A","Nominal output power":"210 W 115 V single phase 410 W 230 V single phase 790 W 400 V three phase 930 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"4","Maximum axial force Fa":"160 N","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"26.02 lbf.in (2.94 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":"900 N 1000 rpm 720 N 2000 rpm 630 N 3000 rpm 570 N 4000 rpm 530 N 5000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"1.8 A","Maximum mechanical speed":"6000 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":"4.5 in (115 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/42ffce4a14969531e0638da04e257a10.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31001M12A1200/sh3-servomotor-100mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31001M12A1200/alternatives.json"},"ai":{"faq":[{"question":"What is SH31001M12A1200's nominal torque at 400 V three-phase?","answer":"At 400 V three-phase the nominal torque is 2.52 N.m (22.30 lbf.in) at 2500 rpm.
