It ships without a holding brake, so any vertical-axis load requires an external brake or a counterbalance. The motor itself is natural-convection cooled — no fan, no forced-air requirement, which simplifies ducting in clean-room or dust-sensitive zones. ## Torque and speed across supply voltages Nominal torque varies by supply: 7.5 N.m at 115 V single-phase, 7.0 N.m at 230 V single-phase, 5.7 N.m at 400 V three-phase, and 5.1 N.m at 480 V three-phase. The continuous stall torque is a flat 8 N.m across the 115–480 V three-phase range, so the motor holds its low-speed torque regardless of line voltage. Peak stall torque reaches 28.3 N.m for short-duration acceleration or high-inertia starts — the drive must be sized to deliver the 28.3 A Irms maximum current to access this peak. Nominal speed scales with voltage: 1000 rpm at 115 V single-phase, 2000 rpm at 230 V single-phase, 4000 rpm at 400 V three-phase, and 4800 rpm at 480 V three-phase. Continuous output power is 2400 W, with nominal output power ranging from 790 W (115 V single-phase) to 2560 W (480 V three-phase). The 4-pole design means 4000 rpm at 133 Hz — a standard servo speed range that pairs with common gearbox ratios. ## Environmental sealing and mechanical limits IP65 on the motor body and shaft bushing, IP67 on the housing — this motor withstands washdown and hose-directed water, suitable for food-and-bev or outdoor conveyor lines. The straight electrical connector mates with a standard cable gland; no right-angle adapter needed for tight side-clearance. Maximum radial force Fr derates with speed: 1050 N at 1000 rpm, dropping to 660 N at 4000 rpm. Maximum axial force Fa is 160 N — direct-drive applications with thrust loads (leadscrews, linear actuators) must stay within this limit or use a thrust bearing. The parallel key shaft end with 19 mm diameter and 40 mm length accepts standard couplings and pulleys. ## Electrical parameters for drive tuning Stator resistance is 1.43 Ω and stator inductance is 4.7 mH — these values set the current-loop PI gains in the drive. The torque constant is 1.22 N.m/A at 120°C copper temperature, and the back-EMF constant is 77 V/krpm at 20°C. At high speeds, the back-EMF approaches the DC-bus voltage; check that the drive's voltage margin accommodates the 4800 rpm condition.","metaTitle":"Schneider Electric SH31003P12A1200 Servo Motor, 2400 W","metaDescription":"Schneider Electric SH31003P12A1200 servo motor, 2400 W continuous, 8 N.m stall torque, IP65/IP67, absolute Hiperface encoder, 100 mm flange.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31003P12A1200","Length":"9.5 in (240.5 mm)","Inertia":"0.0 kg.cm² of brake 3.22 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 100mm, 3 stacks, keyed Shaft, SinCos Multiturn 128, no Brake, straight, IP65/67","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"1.6 in (40 mm)","Holding brake":"Without","Nominal speed":"1000 rpm 115 V single phase 2000 rpm 230 V single phase 4000 rpm 400 V three phase 4800 rpm 480 V three phase","Rotor inertia":"3.22 kg.cm²","Nominal torque":"45.1 lbf.in (5.1 N.m) 480 V three phase 66.4 lbf.in (7.5 N.m) 115 V single phase 62.0 lbf.in (7 N.m) 230 V single phase 50.4 lbf.in (5.7 N.m) 400 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.22 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2400 W","Mounting Support":"International standard flange","Sizing reference":"SH31003P","Back emf constant":"77 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":"4.7 mH","Stator resistance":"1.43 Ohm","Maximum current Irms":"28.3 A","Nominal output power":"790 W 115 V single phase 1470 W 230 V single phase 2390 W 400 V three phase 2560 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":"4.0","Maximum axial force Fa":"160 N","Output current 3s peak":"28.3 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 IP67 housing: 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":"6.6 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7759b00e03eb6bfb0332e259e4173fab.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31003P12A1200/sh3-servomotor-100mm-3-stacks-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31003P12A1200","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/SH31003P12A1200 when reusing this data.
