Overall length is 220 mm from the mounting face to the connector end, with a 14 mm shaft diameter and a 30 mm shaft length that carries a parallel key (5 mm key width). ## Speed and torque across supply voltages This is a three-phase servo motor, but its nominal speed and torque shift depending on what voltage you feed it. On a 400 V three-phase line it spins 3000 rpm and delivers 2.63 N·m; on 480 V three-phase it reaches 3600 rpm at the same torque. Drop to 230 V single-phase and you get 1500 rpm at 2.95 N·m; at 115 V single-phase it's 750 rpm at 3.05 N·m. The continuous power rating follows the same curve: 880 W at 400 V, 1030 W at 480 V, 460 W at 230 V, and 240 W at 115 V. If you're wiring this into a 480 V line, you get the full 1 kW output; on a 230 V line you're limited to about half that. ## Encoder and feedback — absolute multiturn SinCos Hiperface The encoder is an absolute multiturn SinCos Hiperface type — that means it reports position and number of revolutions even after a power loss, no homing cycle needed on startup. The SinCos analog track gives high-resolution speed feedback for smooth velocity loops. ## Cooling and environmental protection Cooling is natural convection — no fan, so the motor relies on surface area and ambient airflow. ## Electrical parameters for drive tuning Stator resistance is 10.7 Ω and inductance is 27.65 mH — these set the electrical time constant and influence the current-loop bandwidth you can achieve with the drive. The torque constant is 1.4 N·m/A at 120°C copper temperature, and the back EMF constant is 95 V/krpm at 20°C, so at 3000 rpm the motor generates 285 V line-to-line back EMF. Maximum continuous current is 8.7 A, and the peak current for 3 seconds is also 8.7 A — this motor doesn't have a separate peak rating above continuous, so any overload beyond 8.7 A must be short enough to stay within the thermal limit. ## Mechanical load limits — radial and axial forces The maximum radial force on the shaft depends on speed: 730 N at 1000 rpm, dropping to 400 N at 6000 rpm. Maximum axial force is 80 N. If you're driving a belt or a direct-coupled load, check that the belt tension or coupling misalignment stays under these limits at your operating speed.","metaTitle":"Schneider Electric SH30703M12A2100 Servo Motor, 830 W","metaDescription":"Schneider Electric SH30703M12A2100 SH3 servo motor, 830 W continuous, 70 mm flange, IP65, 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":"8.7 in (220 mm)","Inertia":"0.0 kg.cm² of brake 0.58 kg.cm² of motor","Key width":"0.2 in (5 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"1.2 in (30 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":"0.58 kg.cm²","Nominal torque":"26.99 lbf.in (3.05 N.m) 115 V single phase 26.11 lbf.in (2.95 N.m) 230 V single phase 23.28 lbf.in (2.63 N.m) 400 V three phase 23.28 lbf.in (2.63 N.m) 480 V three phase","Shaft diameter":"0.6 in (14 mm)","Torque constant":"1.4 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"830 W","Mounting Support":"International standard flange","Sizing reference":"SH30703M","Back emf constant":"95 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"2.8 in (70 mm)","Peak stall torque":"100.01 lbf.in (11.3 N.m) 115...480 V three phase","Stator inductance":"27.65 mH","Stator resistance":"10.7 Ohm","Maximum current Irms":"8.7 A","Nominal output power":"240 W 115 V single phase 460 W 230 V single phase 880 W 400 V three phase 1030 W 480 V three phase","Centring collar depth":"0.10 in (2.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"3","Maximum axial force Fa":"80 N","Output current 3s peak":"8.7 A","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","Maximum radial force Fr":"730 N 1000 rpm 580 N 2000 rpm 510 N 3000 rpm 460 N 4000 rpm 430 N 5000 rpm 400 N 6000 rpm","Mounting holes diameter":"0.2 in (5.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Continuous stall current":"2.1 A","Maximum mechanical speed":"8000 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":"3.2 in (82 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/63dd40dd2b4cd967c6b6a09cc5b55966.pdf","sourceUrl":"https://www.se.com/us/en/product/SH30703M12A2100/sh3-servomotor-70mm-3-stacks-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-angular-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH30703M12A2100/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy SH30703M12A2100 and get a price?","answer":"Submit an RFQ for current availability and pricing."},{"question":"What is SH30703M12A2100's phase and length?","answer":"It is a three-phase motor with an overall length of 220 mm (8.7 in)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH30703M12A2100","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/SH30703M12A2100 when reusing this data.
