The 100 mm flange (IEC standard) and 19 mm shaft with parallel key match the SH3 frame footprint — a direct fit for existing SH3-based machine designs. Nominal torque and speed vary with supply voltage: 7.8 Nm at 500 rpm on 115 V single phase, 7.5 Nm at 1000 rpm on 230 V single phase, 7 Nm at 2000 rpm on 400 V three phase, and 6.76 Nm at 2400 rpm on 480 V three phase. The peak stall torque reaches 28.3 Nm — useful for short-duration acceleration or overcoming load inertia during start-up. The motor uses natural convection cooling (no fan), so the thermal budget depends on the mounting surface and ambient airflow. The IP65 rating on both the motor body and shaft bushing means it withstands washdown environments — suitable for food processing or wet machining lines where hose-down cleaning is routine. ## Absolute multiturn Hiperface encoder — position feedback without homing The encoder is an absolute multiturn SinCos Hiperface type — it reports the absolute shaft position over multiple revolutions without needing a battery-backed counter or a homing sequence after power loss. The SinCos analog track provides high-resolution velocity feedback for the drive's current loop, while the digital Hiperface protocol handles the absolute position data. The torque constant is 2.35 Nm/A at 120 °C copper temperature, and the back EMF constant is 148 V/krpm at 20 °C. Stator resistance is 5.3 Ω and inductance is 17.4 mH — these values set the current-loop tuning parameters in the drive. The maximum continuous stall current is 3.4 A, with a 3-second peak of 14.7 A for acceleration transients. ## Mounting, shaft loads, and electrical connections Maximum radial force on the shaft is speed-dependent: 1050 N at 1000 rpm, dropping to 660 N at 4000 rpm. Maximum axial force is 160 N. The electrical connection uses a rotatable right-angled connector or a straight connector — both are IP65-rated when mated. The motor is supplied without a holding brake.","metaTitle":"Schneider Electric SH31003M12A1100 Servo Motor, 1500 W, 8 Nm","metaDescription":"Schneider Electric SH31003M12A1100 SH3 servo motor, 1500 W continuous power, 8 Nm continuous stall torque, IP65, absolute multiturn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"9.5 in (240.5 mm)","Inertia":"0.0 kg.cm² of brake 3.22 kg.cm² of motor","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":"500 rpm 115 V single phase 1000 rpm 230 V single phase 2000 rpm 400 V three phase 2400 rpm 480 V three phase","Rotor inertia":"3.22 kg.cm²","Nominal torque":"69.04 lbf.in (7.8 N.m) 115 V single phase 66.4 lbf.in (7.5 N.m) 230 V single phase 62.0 lbf.in (7 N.m) 400 V three phase 59.83 lbf.in (6.76 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"2.35 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1500 W","Mounting Support":"International standard flange","Sizing reference":"SH31003M","Back emf constant":"148 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"250.5 lbf.in (28.3 N.m) 115...480 V three phase","Stator inductance":"17.4 mH","Stator resistance":"5.3 Ohm","Maximum current Irms":"14.7 A","Nominal output power":"410 W 115 V single phase 790 W 230 V single phase 1470 W 400 V three phase 1700 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","Output current 3s peak":"14.7 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"70.8 lbf.in (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","Maximum radial force Fr":"1050 N 1000 rpm 830 N 2000 rpm 730 N 3000 rpm 660 N 4000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"3.4 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/87b142079a9780ec75be3e2a377f8cb2.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31003M12A1100/sh3-servomotor-100mm-3-stacks-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M12A1100/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31003M12A1100","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/SH31003M12A1100 when reusing this data.
