The nominal speed depends on the supply: 500 rpm on 115 V single-phase, 1000 rpm on 230 V single-phase, 2000 rpm on 400 V three-phase, and 2400 rpm on 480 V three-phase. That speed range means one motor covers both low-speed positioning and higher-throughput transfer lines, but the drive must be configured for the actual line voltage. Nominal torque varies with voltage too: 7.8 N.m at 115 V single-phase, dropping to 6.76 N.m at 480 V three-phase. The holding brake delivers 9 N.m — enough to hold a vertical axis load at rest without servo drive power, which is the main reason this variant gets specified over the non-brake version. Peak stall torque is 28.3 N.m across the 115–480 V three-phase range, giving a 3.5× overload margin for acceleration or overcoming static friction. Maximum continuous current is 14.7 A, and the 3-second peak current is the same figure — the drive's continuous rating must match or exceed this to avoid I²t trips during sustained moves. The torque constant is 2.35 N.m/A at 120 °C copper temperature, so the drive current loop gain should be tuned to that hot-copper value, not the cold motor resistance. ## Encoder, feedback, and position hold The encoder is an absolute single-turn SinCos Hiperface type — position is known immediately on power-up without a homing cycle, which saves time on multi-axis machines after a power loss. Single-turn means the absolute position range is one revolution; for multi-turn applications the drive or controller must track turns externally. Back EMF constant is 148 V/krpm at 20 °C — this sets the maximum speed the drive can achieve given its DC bus voltage. At 480 V three-phase input, the bus is roughly 680 VDC, so the motor can reach its 2400 rpm ceiling without field weakening. Stator resistance is 5.3 Ω and inductance is 17.4 mH, which influences the current-loop bandwidth and the PWM ripple current magnitude. ## Environmental sealing and mechanical fit The motor body is rated IP65, the shaft bushing IP65, and the housing IP67 per IEC 60034-5. That means the motor withstands washdown — suitable for food-and-beverage lines or outdoor installations where hose-down cleaning is routine. The straight connector exits axially or radially depending on orientation; the connector itself must be mated with the matching IP-rated cable assembly to maintain the seal. Flange size is 100 mm (3.9 in) with an international standard flange pattern — mounts to standard gearboxes or machine frames without an adapter plate. Centring collar diameter is 95 mm with a 3.5 mm depth, and the four mounting holes are 9 mm diameter on the flange bolt circle. Overall length is 271.5 mm (10.7 in) — check the envelope before committing to a retrofit in a tight cabinet. Shaft diameter is 19 mm (0.7 in) with a parallel key, key width 6 mm, shaft length 40 mm. Maximum radial force at the shaft centre is 1050 N at 1000 rpm, derating to 660 N at 4000 rpm — belt-drive or overhung-load applications must respect this curve to avoid bearing damage. Maximum axial force is 160 N.","metaTitle":"Schneider Electric SH31003M11F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31003M11F1200 servo motor with holding brake, 1500 W continuous, 2400 rpm at 480 V three-phase, IP65/IP67, absolute SinCos Hiperface","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":"Straight 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 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":"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/9e2bb7e2218e41a54967027f3c9755c4.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31003M11F1200/sh3-servomotor-100mm-3-stacks-high-torque-keyed-shaft-sincos-singleturn-128-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M11F1200/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does SH31003M11F1200 use?","answer":"It uses an absolute single-turn SinCos Hiperface encoder.
