The nominal torque sits at 7.8 Nm when fed from 400 V three-phase, dropping to 7 Nm at the same voltage — the torque curve is voltage-dependent, not just speed-dependent. The holding brake delivers 9 Nm of holding torque, which means the motor holds the load at rest without power to the windings — critical for vertical-axis applications where the load would otherwise back-drive the motor. Peak stall torque reaches 28.3 Nm across the 115–480 V three-phase range, giving the drive headroom for acceleration and deceleration without tripping on current limit. ## Speed, encoder, and feedback loop Nominal speed varies with supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. The 4-pole motor design keeps the torque constant at 2.35 Nm/A at 120 °C copper temperature. The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing cycle on power-up — the drive reads the absolute position from the encoder's memory. This eliminates the need for a reference run after every power cycle, saving cycle time in multi-axis pick-and-place or indexing applications. Back EMF constant is 148 V/krpm at 20 °C, which sets the voltage ceiling for high-speed operation — at 2400 rpm the back EMF reaches about 355 V, leaving headroom for the drive's DC bus. ## Mounting and environmental sealing The motor mounts on an international standard flange with a 100 mm flange size and a 95 mm centring collar. Four mounting holes at 9 mm diameter on a 3.7 in (95 mm) centring collar diameter — the bolt pattern matches the standard IEC 100 mm frame. Natural convection cooling — no fan, so no additional noise or maintenance from a cooling fan. The thermal limit is 130 °C copper hot, and the stator resistance of 5.3 Ω and inductance of 17.4 mH define the electrical time constant for the drive's current loop tuning. The motor ships with a rotatable right-angle connector and a straight connector option, giving flexibility in cable routing within the cabinet or cable track.","metaTitle":"Schneider Electric SH31003M11F1100 Servo Motor with Brake","metaDescription":"Schneider Electric SH31003M11F1100 SH3 servo motor with brake, 1500 W continuous power, 100 mm flange, IP65, absolute single-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.7 in (271.5 mm)","Inertia":"0.618 kg.cm² of brake 3.22 kg.cm² of motor","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"1.6 in (40 mm)","Holding brake":"With","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":"3.838 kg.cm²","Holding torque":"79.7 lbf.in (9 N.m)","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/7d25846fcdfb77d2b62b0c146dba8a00.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31003M11F1100/sh3-servomotor-100mm-3-stacks-high-torque-keyed-shaft-sincos-singleturn-128-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M11F1100/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does the SH31003M11F1100 use?","answer":"It uses an absolute single-turn SinCos Hiperface encoder.
