The nominal torque drops as voltage rises — from 164.6 lbf.in (18.6 N.m) at 115 V single-phase down to 85.9 lbf.in (9.7 N.m) at 480 V three-phase — so the application voltage directly sets the available torque at rated speed. Continuous output power also shifts with the supply: 1460 W on 115 V single-phase, 2690 W on 230 V single-phase, 3860 W on 400 V three-phase, and 3660 W on 480 V three-phase. The 3900 W continuous power rating in the spec table corresponds to the three-phase 400 V operating point. ## Peak vs continuous torque — the stall duty boundary Peak stall torque is 531.9 lbf.in (60.1 N.m) across the 115–480 V three-phase range, but the continuous stall torque is limited to 172.6 lbf.in (19.5 N.m) over the same voltage window. That 3:1 ratio means the motor can deliver short bursts for acceleration or overload, but sustained stall or low-speed high-torque operation must stay below the continuous limit to avoid exceeding the 130 °C copper hot temperature ceiling. Natural convection cooling (no fan) means the thermal time constant is longer and the duty cycle in stalled or low-rpm conditions is the binding constraint — forced cooling would raise the continuous torque ceiling, but this motor relies on chassis radiation and airflow across the housing. ## Encoder, brake, and environmental sealing The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — useful for applications where the axis must retain its position reference through a power loss. The holding brake delivers 203.6 lbf.in (23 N.m) static torque, enough to hold a vertical load at rest without servo current. IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5 — the shaft bushing seal is the weaker link in washdown environments; the housing itself handles brief submersion. The straight electrical connector mates without a right-angle adapter, which simplifies cable routing in tight cabinets. ## Mounting dimensions and bearing load limits The 140 mm (5.5 in) flange with an international standard pattern uses four 11 mm mounting holes on a 130 mm centring collar. The smooth 24 mm shaft extends 50 mm — no keyway, so the coupling must transmit torque through a clamping or friction fit. Maximum radial force at the shaft centre is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm; axial force is capped at 300 N. Exceed these and the bearing L10 life drops below the motor's service interval. ## Electrical parameters for drive commissioning Stator resistance is 0.6 Ohm and inductance is 3.855 mH — these set the electrical time constant and influence the current-loop tuning gains in the servo drive. The torque constant is 1.47 N.m/A at 120 °C copper temperature, and the back-EMF constant is 101 V/krpm at 20 °C. Maximum continuous current is 44.1 A RMS, which is also the 3-second peak current rating — the drive's current limit should be set at or below this value to protect the windings.","metaTitle":"Schneider Electric SH31402P02F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31402P02F1200 SH3 servo motor with brake, 3900 W continuous power, IP65/IP67, absolute multiturn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31402P02F1200","Length":"12.2 in (310.5 mm)","Inertia":"1.8 kg.cm² of brake 12.68 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 140mm, 2 stacks, smooth Shaft, SinCos Multiturn 128, Brake, straight, IP65/67","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":"14.48 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","Nominal torque":"164.6 lbf.in (18.6 N.m) 115 V single phase 151.3 lbf.in (17.1 N.m) 230 V single phase 108.9 lbf.in (12.3 N.m) 400 V three phase 85.9 lbf.in (9.7 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.47 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"3900 W","Mounting Support":"International standard flange","Sizing reference":"SH31402P","Back emf constant":"101 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"531.9 lbf.in (60.1 N.m) 115...480 V three phase","Stator inductance":"3.855 mH","Stator resistance":"0.6 Ohm","Maximum current Irms":"44.1 A","Nominal output power":"1460 W 115 V single phase 2690 W 230 V single phase 3860 W 400 V three phase 3660 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","Output current 3s peak":"44.1 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"172.6 lbf.in (19.5 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":"2240 N 1000 rpm 1780 N 2000 rpm 1550 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"13.2 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7443ff44c3b25692e69075f530b32b51.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31402P02F1200/sh3-servomotor-140mm-2-stacks-smooth-shaft-sincos-multiturn-128-brake-straight-ip65-67/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31402P02F1200","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/SH31402P02F1200 when reusing this data.
