Nominal speed depends on supply: 2000 rpm at 115 V single-phase, 4000 rpm at 230 V single-phase, and 8000 rpm at 400 V or 480 V three-phase — the 8000 rpm ceiling makes this a high-speed spindle or light-axis motor, not a direct-drive low-speed torque motor. The absolute single-turn SinCos Hiperface encoder gives position feedback on power-up without a homing cycle — critical for applications where the machine must resume from the last known position after a power loss or emergency stop. ## Mounting and shaft — 55 mm flange, smooth shaft Motor flange size is 55 mm with a 40 mm centring collar and 2 mm collar depth — mounts to the international standard flange pattern (IEC 60034). Smooth shaft, 9 mm diameter, 20 mm shaft length — no keyway, so the coupling or pulley must be clamped or use a set-screw hub. The smooth shaft simplifies balancing at high speed but requires a positive-lock coupling to prevent slip under the 1.5 N.m peak stall torque. IP protection is IP54 at the shaft bushing without the seal ring, IP65 on the motor body and with the shaft seal ring installed — the seal ring is the difference between a dry-machine fit and washdown-capable mounting. ## Torque and thermal limits — what the numbers mean for the drive tune Nominal torque is 0.5 N.m on single-phase supplies, dropping to 0.35 N.m on three-phase 400/480 V — the motor delivers less sustained torque at higher voltage because the winding current limit (2.9 A) is the same, but the back EMF at 8000 rpm reduces the available current for torque production. Continuous stall torque is 0.42 N.m across all supply voltages — this is the torque the motor can hold at zero speed indefinitely without overheating, limited by natural convection cooling. Peak stall torque reaches 1.5 N.m for acceleration or short overloads. Torque constant is 0.58 N.m/A at 120°C copper temperature — the drive's current loop must be tuned to this value. Stator resistance is 41.8 Ohm and inductance 37.13 mH, which sets the electrical time constant and the minimum PWM frequency for smooth current regulation. ## Radial and axial load limits — bearing life at speed Maximum radial force derates with speed: 340 N at 1000 rpm, dropping to 170 N at 8000 rpm — a belt-driven load must be sized against the 8000 rpm limit, not the static rating, or the bearing will fail prematurely. Maximum axial force is 40 N — this is a light axial load rating; any thrust load from a helical gear or fan must be verified against this ceiling.","metaTitle":"Schneider Electric SH30551P01F1000 SH3 Servo Motor with","metaDescription":"Schneider Electric SH30551P01F1000 SH3 servo motor with brake, 290 W continuous power, 8000 rpm at 400/480 V three-phase, absolute single-turn SinCos Hiperface","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH30551P01F1000","Length":"6.3 in (159 mm)","Inertia":"0.021 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, Brake, straight, IP54/65","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"0.8 in (20 mm)","Holding brake":"With","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":"0.08 kg.cm²","Holding torque":"7.08 lbf.in (0.8 N.m)","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/f211891b46d4862523d09469dec867bc.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH30551P01F1000/sh3-servomotor-55mm-1-stack-smooth-shaft-sincos-singleturn-128-brake-straight-ip54-65/"},"ai":{"faq":[{"question":"What is the encoder type on SH30551P01F1000?","answer":"The encoder is an absolute single-turn SinCos Hiperface encoder — it provides position feedback on power-up without requiring a homing sequence."},{"question":"What is the holding brake torque on this servo motor?","answer":"The holding brake torque is 0.8 N.m (7.08 lbf.in) — sufficient to hold the load stationary when the motor is de-energized."},{"question":"What IP rating does SH30551P01F1000 have?","answer":"IP54 at the shaft bushing without the seal ring, IP65 on the motor body and with the shaft seal ring installed — the seal ring determines whether the motor is suitable for washdown environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH30551P01F1000","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/SH30551P01F1000 when reusing this data.
