The peak stall torque reaches 28.3 N.m across the 115...480 V three-phase range, giving a 3.6× overload margin for acceleration and transient loads. Nominal speed varies with the 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 motor has 4 poles and a back EMF constant of 148 V/krpm at 20°C, which sets the voltage ceiling at high speed — the drive bus voltage must exceed the back EMF plus IR drop to maintain current regulation. Continuous stall current is 3.4 A, while the maximum continuous current (Irms) is 14.7 A — the drive must be sized to supply this peak current for the application's duty cycle. The torque constant of 2.35 N.m/A at 120°C copper hot defines the current-to-torque gain for servo loop tuning. ## Encoder feedback and mechanical interface The motor is equipped with an absolute single-turn SinCos Hiperface encoder, which provides position feedback at power-up without requiring a homing cycle — critical for applications where the axis position must be known immediately after a power cycle. The encoder type is a single-turn, so the absolute position range is one mechanical revolution. The shaft is a smooth shaft (no keyway) with a diameter of 19 mm and a shaft length of 40 mm. The motor flange size is 100 mm with a centring collar diameter of 95 mm and a centring collar depth of 3.5 mm, conforming to the international standard flange mounting. Four mounting holes at 9.0 mm diameter on the flange face secure the motor. This variant ships without a holding brake — the application must provide external braking or rely on the drive's holding torque at standstill. The electrical connection uses a straight connector, and the overall motor length is 240.5 mm. ## Environmental sealing and thermal limits The IP protection rating depends on the shaft seal configuration: IP54 with a shaft bushing without shaft seal ring, or IP65 for the motor body and IP65 for the shaft bushing when the seal ring is fitted, per IEC 60034-5. In a washdown or dust-prone environment, the shaft seal ring is required to maintain IP65 at the shaft exit. Cooling is by natural convection only — no forced ventilation or liquid cooling. The maximum copper hot temperature is 130°C. In high-torque or low-speed applications where natural convection is reduced, the duty cycle must be derated to stay within the thermal limit. Maximum radial force at the shaft is 1050 N at 1000 rpm, decreasing to 660 N at 4000 rpm. Maximum axial force is 160 N. These limits govern belt-drive and overhung load applications — exceeding them risks bearing damage. The motor is part of the SH3 series (device short name SH3), with the sizing reference SH31003M.","metaTitle":"Schneider Electric SH31003M01A1000 Servo Motor, 1500 W","metaDescription":"Schneider Electric SH31003M01A1000 SH3 servo motor, 1500 W continuous power, 7.8 Nm nominal torque, absolute single-turn SinCos Hiperface encoder, IP54/IP65.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"9.5 in (240.5 mm)","Inertia":"0.0 kg.cm² of brake 3.22 kg.cm² of motor","Key width":"0.2 in (6 mm)","Shaft end":"Smooth shaft","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"1.6 in (40 mm)","Holding brake":"Without","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":"3.22 kg.cm²","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":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 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/c818d18ed5fcb9e4ffff0b6e9404e464.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31003M01A1000/sh3-servomotor-100mm-3-stacks-high-torque-smooth-shaft-sincos-singleturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M01A1000/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does the SH31003M01A1000 use?","answer":"It uses an absolute single-turn SinCos Hiperface encoder.
