The continuous stall torque is 2.94 N·m across the 115–480 V three-phase range; peak stall torque reaches 9.6 N·m under the same supply conditions. This torque-versus-speed envelope defines the mechanical load it can move and hold without thermal overload — the continuous stall figure governs steady-state positioning, while the peak figure covers acceleration and emergency stops. Nominal output power varies with the supply voltage: 210 W on 115 V single-phase, 410 W on 230 V single-phase, 790 W on 400 V three-phase, and 930 W on 480 V three-phase. The nominal speed follows the same pattern — 625 rpm at 115 V single-phase, 1250 rpm at 230 V single-phase, 2500 rpm at 400 V three-phase, and 3000 rpm at 480 V three-phase. Maximum mechanical speed is 6000 rpm, well above the nominal range, but the torque available above 3000 rpm drops off per the constant-power region of the motor's characteristic. ## Absolute multiturn Hiperface encoder — position retention without homing The encoder is an absolute multiturn SinCos Hiperface type. This means the motor reports its absolute position and the number of shaft revolutions on power-up — no reference run or homing sequence is required after a power cycle. For a pharmaceutical GMP line where every restart must be traceable and repeatable, this eliminates the position-validation step that incremental encoders demand during IQ/OQ. The SinCos analog tracks allow the drive to interpolate position between digital counts, giving sub-micron resolution at the load when paired with a suitable servo drive. The motor carries no holding brake. For vertical-axis applications where the load must stay in position with power off, an external brake or a motor variant with the brake option is required. The straight electrical connector simplifies cable routing — no right-angle strain relief needed on the motor side. The IP rating is IP54 at the shaft bushing without the shaft seal ring, and IP65 with the seal ring fitted. For washdown environments, the IP65 configuration is the minimum entry point; the seal ring must be specified at order time. ## Flange mounting and electrical parameters — integration constraints Mounting uses an international standard flange with a 100 mm flange size. The centring collar diameter is 95 mm with a 3.5 mm depth; the four mounting holes are 9.0 mm diameter on the bolt circle. The shaft is 19 mm diameter, 40 mm long, with a parallel key and 6 mm key width. These dimensions determine the adapter plate or gearbox interface — no custom machining should be needed if the mating part follows IEC standard flange patterns. The SH31001M12A1000 is part of the SH3 device family, with the sizing reference SH31001M. No pin-compatible alternative within the SH3 series is listed as a direct cross-reference — the motor's torque, speed, and encoder configuration are specific to this order code. For a BOM position that requires the absolute multiturn Hiperface encoder and the 100 mm flange, this is the exact part.","metaTitle":"Schneider Electric SH31001M12A1000 Servo Motor, 660 W","metaDescription":"Schneider Electric SH31001M12A1000 SH3 servo motor, 660 W continuous power, 2.94 N·m continuous stall torque, absolute multiturn SinCos Hiperface encoder","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":"Straight 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":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: 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/bc26384f922bfbb9d173fc490b28b426.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31001M12A1000/sh3-servomotor-100mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31001M12A1000/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous stall torque of SH31001M12A1000?","answer":"The continuous stall torque is 2.94 N·m across the 115–480 V three-phase range.
