The peak stall torque ceiling is 1.5 N.m at 115…480 V three phase, so the motor takes a 3× overload spike for short acceleration moves — useful for indexing duty where the dwell is short and the move-and-settle window is tight. Continuous power is 290 W, nominal output power 160 W at 230 V single phase and 290 W at 400 V or 480 V three phase, with the continuous stall torque 0.42 N.m at 0.73 A and peak Irms 2.9 A for a 3-second burst. Torque constant is 0.58 N.m/A at 120 °C copper hot with stator resistance 41.8 Ohm and inductance 37.13 mH — winding figures the drive's auto-tune routine reads directly to set the current loop gains. Mechanical speed ceiling is 9000 rpm and the back-EMF constant 40 V/krpm at 20 °C — at full speed on a 480 V bus the generated EMF sits well below the DC-link, leaving headroom for the drive to command full current through the upper speed range without field weakening. ## Feedback and wiring Feedback is an absolute single-turn Hiperface DSL encoder — the drive side must support the Hiperface DSL protocol on a single cable pair; pairing this motor with a Lexium 32 or Lexium 28S drive is the conventional match, and the encoder resolution comes from the DSL link rather than from a separate resolver or second cable. Power and feedback ride through a single rotatable right-angle quicklock connector, which lets the cable exit in any of four directions without re-terminating — handy in a tight cabinet where the cable duct dictates the exit angle. Cooling is natural convection, so no fan cable and no fan-failure fault to plan for; the motor flange itself is the heatsink, and the maximum axial force is 40 N with maximum radial force 340 N at 1000 rpm — beyond 1000 rpm the radial load derates further per the curve. ## Lifecycle read Lifecycle stage reads as 'current', so the part is still on the Schneider Electric catalogue. Independent distribution quotes this code against the BOM quantity; lead time and volume pricing come back with the RFQ, no factory-direct commitment implied. No official successor or cross-reference is listed on this entry, so any second-source path is a parametric match in the SH3 55 mm frame rather than a guaranteed drop-in.","metaTitle":"SH30551P1AA4100 Schneider Servo Motor, 0.5 N.m, 4000 rpm","metaDescription":"Schneider Electric SH30551P1AA4100 SH3 servo motor, 0.5 N.m nominal, 4000 rpm at 230 V, Hiperface DSL encoder, IP65, quoted to order against the BOM.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"SH30551P1AA4100","Length":"132.5 mm","Inertia":"0.0 kg.cm² of brake 0.059 kg.cm² of motor","Key width":"3 mm","Shaft end":"Parallel key","description":"SH3 servomotor, 55mm, 1 stack, keyed Shaft, Singleturn DSL 18bit, no Brake, OneMotorCable angular M17, IP65/65","Encoder type":"Absolute single turn Hiperface DSL","Shaft length":"20 mm","Holding brake":"Without","Nominal speed":"4000 rpm at 230 V single phase 8000 rpm at 400 V three phase 9000 rpm at 480 V three phase","Rotor inertia":"0.059 kg.cm²","Nominal torque":"0.5 N.m at 230 V single phase 0.35 N.m at 400 V three phase 0.35 N.m at 480 V three phase","Product weight":"1.2 kg","Shaft diameter":"9 mm","Torque constant":"0.58 N.m/A at 120 °C","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"290 W","Mounting support":"International standard flange","Sizing reference":"SH30551P","Back emf constant":"40 V/krpm at 20 °C","Device short name":"SH3","Motor flange size":"55 mm","Peak stall torque":"1.5 N.m at 115...480 V three phase","Stator inductance":"37.13 mH","Stator resistance":"41.8 Ohm","Maximum current Irms":"2.9 A","Nominal output power":"160 W at 230 V single phase 290 W at 400 V three phase 290 W at 480 V three phase","Centring collar depth":"2 mm","Electrical connection":"quicklock rotatable right angled connector","Number of motor poles":"3.0","Maximum axial force Fa":"40 N","Output current 3s peak":"2.9 A","Temperature copper hot":"130 °C","Continuous stall torque":"0.42 N.m at 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":"340 N at 1000 rpm","Mounting holes diameter":"5.5 mm","Centring collar diameter":"40 mm","Continuous stall current":"0.73 A","Maximum mechanical speed":"9000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or component type":"Servo motor","Speed feedback resolution":"262144 points/turn","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"63 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b35811797e3f213a269f605f75887673.pdf","sourceUrl":"https://www.se.com/uk/en/product/SH30551P1AA4100/sh3-servomotor-55mm-1-stack-keyed-shaft-singleturn-dsl-18bit-no-brake-onemotorcable-angular-m17-ip65-65/"},"ai":{"faq":[{"question":"What torque and speed does SH30551P1AA4100 actually deliver on a 230 V supply?","answer":"On 230 V single phase the motor runs 0.5 N.m nominal at 4000 rpm.
