Single-phase 115 V yields 750 rpm / 3.05 N·m, and 230 V single-phase gives 1500 rpm / 2.95 N·m — so the same motor covers both line voltages and phase configurations, but the integrator sizes the drive and cables for the actual supply. Peak stall torque hits 11.3 N·m across the 115–480 V three-phase range, while continuous stall torque is 2.94 N·m at 2.1 A continuous stall current. The 8.7 A maximum current (3 s peak) defines the drive's peak current requirement — match the servo drive to at least this peak for full torque delivery during acceleration. ## Encoder feedback and mechanical interface The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — critical for applications that must resume position after a power loss. The rotatable right-angle connector and straight connector options give flexibility in cable routing within tight cabinets. Smooth shaft (no keyway) on a 14 mm diameter, 30 mm shaft length with a 5 mm key width. The international standard flange is 70 mm with a 60 mm centring collar and 2.5 mm centring collar depth. Mounting holes are 5.5 mm diameter — standard M5 or equivalent hardware. ## Environmental sealing and thermal limits Cooling is natural convection only; no external fan or liquid cooling — derate if mounted in a confined space with restricted airflow. Copper hot temperature limit is 130 °C. The torque constant is 1.4 N·m/A at 120 °C, and back EMF constant is 95 V/krpm at 20 °C — these thermal coefficients matter when the motor runs near its thermal ceiling; expect torque constant to drop and back EMF to rise as winding temperature increases. ## Bearing load capacity and radial force derating Maximum radial force Fr is 730 N at 1000 rpm, derating to 400 N at 6000 rpm — the bearing life is directly affected by belt tension or direct-drive overhung loads. Maximum axial force Fa is 80 N. For belt-driven applications, calculate the resultant radial load at the operating speed and stay below the curve to avoid premature bearing failure.","metaTitle":"Schneider SH30703M02A1200 Servo Motor, 830 W, 3000 rpm","metaDescription":"Schneider Electric SH30703M02A1200 SH3 servo motor, 830 W continuous, 3000 rpm at 400 V three-phase, absolute multiturn encoder, IP65/IP67.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"8.7 in (220 mm)","Inertia":"0.0 kg.cm² of brake 0.58 kg.cm² of motor","Key width":"0.2 in (5 mm)","Shaft end":"Smooth shaft","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"1.2 in (30 mm)","Holding brake":"Without","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":"0.58 kg.cm²","Nominal torque":"26.99 lbf.in (3.05 N.m) 115 V single phase 26.11 lbf.in (2.95 N.m) 230 V single phase 23.28 lbf.in (2.63 N.m) 400 V three phase 23.28 lbf.in (2.63 N.m) 480 V three phase","Shaft diameter":"0.6 in (14 mm)","Torque constant":"1.4 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"830 W","Mounting Support":"International standard flange","Sizing reference":"SH30703M","Back emf constant":"95 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"2.8 in (70 mm)","Peak stall torque":"100.01 lbf.in (11.3 N.m) 115...480 V three phase","Stator inductance":"27.65 mH","Stator resistance":"10.7 Ohm","Maximum current Irms":"8.7 A","Nominal output power":"240 W 115 V single phase 460 W 230 V single phase 880 W 400 V three phase 1030 W 480 V three phase","Centring collar depth":"0.10 in (2.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"3","Maximum axial force Fa":"80 N","Output current 3s peak":"8.7 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"26.02 lbf.in (2.94 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":"730 N 1000 rpm 580 N 2000 rpm 510 N 3000 rpm 460 N 4000 rpm 430 N 5000 rpm 400 N 6000 rpm","Mounting holes diameter":"0.2 in (5.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Continuous stall current":"2.1 A","Maximum mechanical speed":"8000 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":"3.2 in (82 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/49e3d78b98bf519495fe5a7a7df03795.pdf","sourceUrl":"https://www.se.com/nl/en/product/SH30703M02A1200/sh3-servomotor-70mm-3-stacks-high-torque-smooth-shaft-sincos-multiturn-128-no-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH30703M02A1200/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does this servo motor use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder — no homing cycle needed after power loss, and the SinCos interface provides high-resolution position feedback compatible with most Schneider and third-party servo drives that support Hiperface."},{"question":"What is the IP rating and what environments can it handle?","answer":"IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5.
