Four mounting holes at 0.4 in (11 mm) diameter — the bolt circle matches the common IEC frame size for this power class. The shaft is 0.9 in (24 mm) diameter, 2.0 in (50 mm) long, with a parallel key and 0.3 in (8 mm) keyway. Overall body length is 10.06 in (255.5 mm). The electrical connection is a straight connector — no right-angle adapter needed, which simplifies cable routing in tight cabinets. IP65 protection on both the motor body and the shaft bushing per IEC 60034-5 means this motor handles washdown and airborne particulates without an additional cover — something to confirm if the application sees direct spray at the seal face. ## Torque and speed profile across supply voltages This is a multi-voltage motor — it delivers different nominal speeds depending on the supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. That range means the same frame can serve a 50 Hz line or a 60 Hz line without a motor swap. Nominal torque varies with voltage too: 10.95 N.m at 115 V single-phase, 10.6 N.m at 230 V single-phase, 9.2 N.m at 400 V three-phase, and 8.4 N.m at 480 V three-phase. Continuous stall torque is 11.1 N.m across the three-phase range. Peak stall torque reaches 27 N.m — useful for short-duration acceleration events. Continuous power is 2900 W, with nominal output power ranging from 860 W (115 V single-phase) up to 3170 W (480 V three-phase). The torque constant is 1.43 N.m/A at 120 °C copper temperature — a figure to use when sizing the drive current loop. ## Encoder, brake, and feedback — what the absolute multitap means The encoder is an absolute multiturn SinCos Hiperface type — it reports both position within one revolution and the total revolution count, so the drive knows the shaft position immediately on power-up without a homing routine. This saves cycle time on machines that power-cycle between batches. The holding brake delivers 23 N.m holding torque — enough to hold a vertical-axis load at rest when power is removed. The motor is listed with the brake included, so no separate brake resistor or external holding circuit is needed for the hold function. ## Electrical parameters for drive sizing Stator resistance is 1.41 Ohm and inductance is 23.72 mH — these set the electrical time constant and influence the drive's current regulator tuning. Maximum RMS current is 20.8 A; continuous stall current is 7.8 A. The drive must be rated to supply at least the peak current during acceleration. Back EMF constant is 100 V/krpm at 20 °C. This determines the bus voltage needed to reach a given speed — at 3600 rpm the back EMF is 360 V, so a 480 V bus has headroom for current regulation. Cooling is natural convection — no forced air or liquid cooling. The motor relies on its own surface area and the ambient airflow. In a confined cabinet or at low speeds with high continuous torque, check that the ambient stays within the copper temperature limit of 130 °C. No stock-holding claim is made here — each RFQ is handled individually. If a second-source or replacement is needed, the sizing reference SH31401P points to the same frame family, but the specific encoder and brake configuration should be matched against the application requirements.","metaTitle":"Schneider Electric SH31401P12F1100 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401P12F1100 servo motor with holding brake, 2.9 kW continuous power, IP65, absolute multiturn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.06 in (255.5 mm)","Category":"18359-PACDRIVE3 SERVO MOTORS","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"With","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"9.21 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","Nominal torque":"96.92 lbf.in (10.95 N.m) 115 V single phase 93.8 lbf.in (10.6 N.m) 230 V single phase 81.4 lbf.in (9.2 N.m) 400 V three phase 74.3 lbf.in (8.4 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.43 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2900 W","Mounting Support":"International standard flange","Sizing reference":"SH31401P","Back emf constant":"100 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"239.0 lbf.in (27 N.m) 115...480 V three phase","Stator inductance":"23.72 mH","Stator resistance":"1.41 Ohm","Maximum current Irms":"20.8 A","Nominal output power":"860 W 115 V single phase 1670 W 230 V single phase 2890 W 400 V three phase 3170 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":"5","Maximum axial force Fa":"300 N","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"98.2 lbf.in (11.1 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":"1930 N 1000 rpm 1530 N 2000 rpm 1340 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"7.8 A","Maximum mechanical speed":"4000 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":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c1bbe4bc08d023c50656821c39cbab15.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401P12F1100/sh3-servomotor-140mm-1-stack-keyed-shaft-sincos-multiturn-128-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P12F1100/alternatives.json"},"ai":{"faq":[{"question":"How do I get pricing and availability for the SH31401P12F1100?","answer":"No stock-holding figure is published here."},{"question":"What is the closest alternative to the SH31401P12F1100 in the same family?","answer":"The sizing reference SH31401P indicates the same frame and flange family, but the specific encoder (absolute multiturn Hiperface) and integrated brake configuration should be verified against any proposed substitute."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31401P12F1100","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/SH31401P12F1100 when reusing this data.
