The nominal torque holds at 0.5 N.m on single-phase supplies but drops to 0.35 N.m on three-phase, while continuous power climbs from 100 W at 115 V single-phase to 440 W at 480 V three-phase. The continuous stall torque is 0.42 N.m across the 115-480 V three-phase range, with a continuous stall current of 0.73 A. Peak stall torque reaches 1.5 N.m — roughly 3.6× the continuous stall figure — giving you headroom for acceleration transients without oversizing the drive. ## Absolute single-turn encoder — no homing, but one-revolution limit The absolute single-turn SinCos Hiperface encoder means the motor knows its position within one revolution at power-up — no homing sequence needed on every cycle. The trade-off: single-turn tracks position within 360° only; multi-turn applications need a different encoder option or an external multi-turn battery backup on the drive side. The back EMF constant is 40 V/krpm at 20°C, and the torque constant is 0.58 N.m/A at 120°C copper temperature — these two numbers let you size the drive's DC bus voltage and current loop gain before you wire a cable. ## Holding brake and IP65 — vertical-axis and washdown duty The integrated holding brake delivers 0.8 N.m holding torque — enough to hold a light vertical axis at rest without servo current draw. The brake is a power-off engaged type (typical for servo motors), so the axis stays put on a power loss. The straight electrical connector is the wet-end interface; keep the mating cordset's O-ring seated to maintain the seal. ## Low inertia, high resistance — fast acceleration with thermal limits Maximum mechanical speed is 9000 rpm — the bearing and rotor balance limit, not the winding insulation. The maximum radial force Fr drops from 340 N at 1000 rpm to 170 N at 8000 rpm, so a direct-coupled load at high speed needs a lighter rotor or a compliant coupling.","metaTitle":"Schneider Electric SH30551P11F1100 Servo Motor with Brake","metaDescription":"Schneider Electric SH30551P11F1100 SH3 servo motor with holding brake, 290 W continuous, IP65, absolute single-turn Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"6.3 in (159 mm)","Key width":"0.1 in (3 mm)","Shaft end":"Parallel key","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 6000 rpm 400 V three phase 6000 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":"108.72 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":"Straight connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"3","Maximum axial force Fa":"40 N","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":"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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0b1257e63b8ccdee03909f3ac9b7c802.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH30551P11F1100/servo-motor-sh3-055-05nmkeysinglebrakestr-connip65-ip659k-rpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH30551P11F1100/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and phase does this SH30551P11F1100 motor require?","answer":"The motor is wound for three-phase operation, but the performance table shows it runs on single-phase supplies as well — 115 V or 230 V single-phase — with reduced speed and torque.
