Lifecycle stage is current, so the part is on the active catalogue line (cites:). The body carries IP65 at the motor housing with IP54 at the shaft bushing when no seal ring is fitted (cites:). Servo motors in this class drive the rotary axis on a packaging, pick-and-place, or feed-and-cut line under a Lexium or third-party drive, using Hiperface DSL to push absolute single-turn position and commutation data over a single cable pair back to the servo drive (cites:). The 55 mm flange and 132.5 mm length put it in the small-frame bracket shared by light-duty index tables, labelling heads, and small gantry axes where inertia matters more than stall torque (cites:). Nominal output power is 160 W on a 230 V single-phase supply and 290 W on either 400 V or 480 V three-phase rails, with a 290 W continuous-power figure on the same envelope (cites:). Nominal torque follows the same shape: 0.5 N·m at 230 V single-phase against 0.35 N·m on the 400 V and 480 V three-phase rails, the lower figure reflecting the higher current-loop bandwidth available when the bus is stiffer (cites:). Nominal speed tracks the supply: 4000 rpm at 230 V single-phase, 8000 rpm at 400 V three-phase, and 9000 rpm at 480 V three-phase, with the mechanical ceiling matching the 480 V rating at 9000 rpm (cites:). For a sizing engineer this means a single SKU drives axes with very different speed demands by selecting the bus voltage; the motor, flange, and encoder stay the same (cites:). Continuous stall torque lands at 0.42 N·m across the 115 V to 480 V three-phase range, with a continuous stall current of 0.73 A drawing through the windings (cites:). Peak stall torque reaches 1.5 N·m at the same 115 V to 480 V three-phase window, so the motor can briefly deliver roughly 3.5× its continuous torque before the drive's current limit or the motor's thermal curve intervenes (cites:). The drive sizing constants are recorded for the parameter set: torque constant 0.58 N·m/A at 120 °C, back-EMF constant 40 V/krpm at 20 °C, stator resistance 41.8 Ohm, and stator inductance 37.13 mH (cites:). Maximum Irms and 3-second peak current both sit at 2.9 A, a figure the drive commissioning engineer uses to set the current loop gain and the peak torque limit (cites:). ## Mechanical envelope, mounting, and shaft load limits Cooling is natural convection, so there is no fan or IP-rated duct to fail; the copper-hot thermal limit of 130 °C is what the drive's I²T model monitors against when sizing the continuous load (cites:). For a panel builder integrating the motor into a sealed machine the IP65 housing rating carries through the cable outlet, while the shaft bushing drops to IP54 unless a shaft seal ring is fitted (cites:).","metaTitle":"Schneider SH30551P0AA4000 SH3 servo motor, 55 mm flange","metaDescription":"Schneider Electric SH30551P0AA4000 servo motor in the SH3 family, 55 mm flange, 0.35–0.5 N·m continuous, Hiperface DSL feedback.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"SH30551P0AA4000","Length":"132.5 mm","Inertia":"0.0 kg.cm² of brake 0.059 kg.cm² of motor","Shaft end":"Smooth shaft","description":"SH3 servomotor, 55mm, 1 stack, smooth Shaft, Singleturn DSL 18bit, no Brake, OneMotorCable angular M17, IP54/65","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 IP54 shaft bushing without shaft seal ring: 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/250961172c39c9574ba36b40d3e91578.pdf","sourceUrl":"https://www.se.com/uk/en/product/SH30551P0AA4000/sh3-servomotor-55mm-1-stack-smooth-shaft-singleturn-dsl-18bit-no-brake-onemotorcable-angular-m17-ip54-65/"},"ai":{"faq":[{"question":"What is the listed length of SH30551P0AA4000?","answer":"SH30551P0AA4000 ships at 132.5 mm overall length with a 55 mm flange and a 9 mm smooth shaft (cites:).
