At 400 V three-phase it makes 4.6 Nm at 4000 rpm; drop to 115 V single-phase and torque climbs to 5.5 Nm but speed caps at 1000 rpm. The peak stall torque is 18.3 Nm across the 115...480 V three-phase range — that's the number for sizing acceleration and emergency stops, not the continuous figure. The continuous stall torque is 5.8 Nm, and that's the holding torque at zero speed with natural convection cooling. No forced air needed — the motor sheds heat through the flange and housing, so panel airflow matters more than a dedicated fan. ## Encoder and feedback — absolute single-turn SinCos Hiperface The absolute single-turn SinCos Hiperface encoder gives position on power-up without a homing move — the drive reads the absolute position within one revolution. That saves a reference cycle on every power cycle, which matters on multi-axis machines where you don't want to re-home after a power dip. The torque constant is 1.21 Nm/A at 120 °C copper temperature. That's the hot value — the cold torque constant will be slightly higher because the magnets are stronger at ambient. Use the hot figure for worst-case drive current sizing. Back EMF constant is 77 V/krpm at 20 °C. Match this to the drive's DC bus voltage: at 4000 rpm the motor generates 308 V back EMF, leaving headroom for the drive to inject current above that voltage. If the bus is too low, the drive loses torque at high speed. ## Mounting and environmental fit Flange size is 100 mm (3.9 in) with a 95 mm centring collar and 9 mm mounting holes — standard international flange pattern. Overall length is 204.5 mm (8.05 in) from the mounting face to the rear of the housing. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, 6 mm key width. IP65 on the motor body and shaft bushing, IP67 on the housing — that's washdown-capable per IEC 60034-5. The rotatable right-angle connector or straight connector option lets you route the cable to clear adjacent hardware. No holding brake on this variant, so vertical-axis applications need an external brake or a counterbalance. ## Drive tuning and electrical parameters Stator resistance is 2.4 Ohm and inductance is 6.75 mH — those set the electrical time constant and the current-loop tuning gains. Maximum RMS current is 17.1 A, and the 3-second peak output current is the same 17.1 A, so the drive's peak current limit should match or exceed that. Four-pole motor, natural convection cooling. Maximum radial force at the shaft is 990 N at 1000 rpm, dropping to 620 N at 4000 rpm — bearing life is a function of both radial load and speed, so don't oversize the belt tension at high rpm. Maximum axial force is 160 N.","metaTitle":"Schneider Electric SH31002P11A1200 Servo Motor, 1900 W","metaDescription":"Schneider Electric SH31002P11A1200 SH3 servo motor, 1900 W continuous power, 4000 rpm nominal speed, 5.8 Nm continuous stall torque, IP65/IP67, absolute","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31002P11A1200","Length":"8.05 in (204.5 mm)","Inertia":"0.0 kg.cm² of brake 2.31 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 100mm, 2 stacks, keyed Shaft, SinCos Singleturn 128, no Brake, straight, IP65/67","Encoder type":"Absolute single turn 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":"2.31 kg.cm²","Nominal torque":"48.7 lbf.in (5.5 N.m) 115 V single phase 46.02 lbf.in (5.2 N.m) 230 V single phase 40.7 lbf.in (4.6 N.m) 400 V three phase 38.9 lbf.in (4.4 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.21 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1900 W","Mounting Support":"International standard flange","Sizing reference":"SH31002P","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":"162.0 lbf.in (18.3 N.m) 115...480 V three phase","Stator inductance":"6.75 mH","Stator resistance":"2.4 Ohm","Maximum current Irms":"17.1 A","Nominal output power":"580 W 115 V single phase 1090 W 230 V single phase 1930 W 400 V three phase 2210 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":"4.0","Maximum axial force Fa":"160 N","Output current 3s peak":"17.1 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"51.3 lbf.in (5.8 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":"990 N 1000 rpm 790 N 2000 rpm 690 N 3000 rpm 620 N 4000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"4.8 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/603472643bdf98d7260af6fd19060fbb.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31002P11A1200/sh3-servomotor-100mm-2-stacks-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What is the continuous power rating of SH31002P11A1200?","answer":"The continuous power rating is 1900 W.
