That means the same motor frame covers a 4:1 speed range depending on the drive's DC bus voltage — critical for a BOM that must work across global line voltages. Continuous power is 290 W, with nominal output power varying from 100 W at 115 V single phase up to 440 W at 480 V three phase. The motor is rated for natural convection cooling — no fan, so heat rejection depends on the mounting flange's thermal path to the machine frame. ## Absolute Hiperface encoder — no homing sequence needed The absolute single-turn SinCos Hiperface encoder provides position feedback on power-up without a reference run — the drive knows the rotor angle immediately. This saves cycle time in multi-axis machines where homing would otherwise add seconds per axis on every startup. Back EMF constant is 40 V/krpm at 20°C, and torque constant is 0.58 N.m/A at 120°C hot winding temperature. The 130°C copper temperature limit sets the thermal budget for continuous stall current of 0.73 A and continuous stall torque of 0.42 N.m. Peak stall torque reaches 1.5 N.m at 115-480 V three phase with a 2.9 A peak current for up to 3 seconds — useful for breaking static friction or accelerating a load through a short high-torque window. ## Smooth shaft, no brake — coupling and load-holding decisions The shaft is smooth (no keyway) with a 9 mm diameter and 20 mm engagement length. This requires a clamping-type coupling or a friction-lock pulley — no positive drive via key. Maximum radial force Fr derates with speed: 340 N at 1000 rpm down to 170 N at 8000 rpm; maximum axial force Fa is 40 N. ## Active production — sourced to order The 55 mm international standard flange with 40 mm centring collar and 5.5 mm mounting holes fits standard servo-mount patterns. Electrical connection options are a rotatable right-angled connector or a straight connector — choose based on cable exit clearance in the panel.","metaTitle":"Schneider SH30551P01A1000 Servo Motor, 290 W, 8000 rpm","metaDescription":"Schneider Electric SH30551P01A1000 servo motor, 290 W continuous, 8000 rpm at 480 V three phase, 0.5 N.m torque, absolute SinCos Hiperface encoder, smooth","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH30551P01A1000","Length":"5.2 in (132.5 mm)","Inertia":"0.0 kg.cm² of brake 0.059 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 55mm, 1 stack, smooth Shaft, SinCos Singleturn 128, no Brake, straight, IP54/65","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"0.8 in (20 mm)","Holding brake":"Without","Nominal speed":"2000 rpm 115 V single phase 4000 rpm 230 V single phase 8000 rpm 400 V three phase 8000 rpm 480 V three phase","Rotor inertia":"0.059 kg.cm²","Nominal torque":"4.4 lbf.in (0.5 N.m) 115 V single phase 4.4 lbf.in (0.5 N.m) 230 V single phase 3.10 lbf.in (0.35 N.m) 400 V three phase 3.10 lbf.in (0.35 N.m) 480 V three phase","Shaft diameter":"0.4 in (9 mm)","Torque constant":"0.58 N.m/A 248 °F (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 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"2.2 in (55 mm)","Peak stall torque":"13.3 lbf.in (1.5 N.m) 115...480 V three phase","Stator inductance":"37.13 mH","Stator resistance":"41.8 Ohm","Maximum current Irms":"2.9 A","Nominal output power":"100 W 115 V single phase 210 W 230 V single phase 400 W 400 V three phase 440 W 480 V three phase","Centring collar depth":"0.08 in (2 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"3.0","Maximum axial force Fa":"40 N","Output current 3s peak":"2.9 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"3.72 lbf.in (0.42 N.m) 115...480 V three phase","IP degree of protection":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5","Maximum radial force Fr":"340 N 1000 rpm 270 N 2000 rpm 240 N 3000 rpm 220 N 4000 rpm 200 N 5000 rpm 190 N 6000 rpm 180 N 7000 rpm 170 N 8000 rpm","Mounting holes diameter":"0.2 in (5.5 mm)","Centring collar diameter":"1.6 in (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":"128 periods","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"2.5 in (63 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/06bcaa78e7d484ddf584809a6f2ad3eb.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH30551P01A1000/sh3-servomotor-55mm-1-stack-smooth-shaft-sincos-singleturn-128-no-brake-straight-ip54-65/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH30551P01A1000","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/SH30551P01A1000 when reusing this data.
