Nominal torque also varies by voltage — 7.8 N·m at 115 V single-phase, 7.5 N·m at 230 V single-phase, 7 N·m at 400 V three-phase, and 6.76 N·m at 480 V three-phase. The continuous power rating is 1500 W, with peak stall torque reaching 28.3 N·m across the 115–480 V three-phase range. The holding brake delivers 9 N·m of holding torque, which matches the nominal torque range — important for vertical-axis applications where the load must stay put when power is removed. ## Encoder and feedback — absolute multiturn SinCos Hiperface The encoder is an absolute multiturn SinCos Hiperface type — this gives position feedback at power-up without a homing cycle, and the SinCos analog track provides fine interpolation for velocity control. The motor has 4 poles, and the back EMF constant is 148 V/krpm at 68 °F (20 °C). Stator inductance is 17.4 mH and stator resistance is 5.3 Ohm — these values matter for the drive tuning parameters (current loop gains) and for estimating the L/R time constant during commissioning. ## Mounting and environmental fit The motor uses an international standard flange with a 100 mm flange size and a 3.5 mm centring collar depth. The shaft is 19 mm diameter with a parallel key (6 mm key width) and 40 mm shaft length. Mounting holes are 9 mm diameter on a 95 mm centring collar diameter. IP protection is IP54 at the shaft bushing without a shaft seal ring, and IP65 for the motor body and with a shaft bushing — conforming to IEC 60034-5. This means the motor body handles washdown environments, but the shaft exit needs the seal ring for IP65 integrity. Cooling is natural convection — no external fan, so the thermal budget depends on the mounting surface and ambient airflow. Maximum radial force is 1050 N at 1000 rpm, derating to 660 N at 4000 rpm. Maximum axial force is 160 N. These limits govern the allowable belt tension or direct coupling load on the shaft.","metaTitle":"Schneider Electric SH31003M12F1000 Servo Motor with Brake","metaDescription":"Schneider Electric SH31003M12F1000 SH3 servo motor, 1500 W continuous power, 9 N·m holding brake, absolute multiturn 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":"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 multiturn 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":"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/a184e18b494eedd70067df5eaab640a4.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31003M12F1000/sh3-servomotor-100mm-3-stacks-high-torque-keyed-shaft-sincos-multiturn-128-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M12F1000/alternatives.json"},"ai":{"faq":[{"question":"What is the holding torque of the brake on SH31003M12F1000?","answer":"The holding brake delivers 9 N·m (79.7 lbf·in) of holding torque."},{"question":"What encoder type does SH31003M12F1000 use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder — provides position at power-up without homing."},{"question":"What IP rating does SH31003M12F1000 have?","answer":"IP54 at the shaft bushing without seal ring; IP65 for the motor body and with shaft bushing — conforming to IEC 60034-5."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31003M12F1000","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/SH31003M12F1000 when reusing this data.
