This frame size and power class fit compact motion axes — pick-and-place gantries, labeling stations, or small conveyor indexing where the motor mounts directly to the machine frame without a gearbox. Three-phase supply only — the motor delivers its full torque and speed envelope on 400 V or 480 V three-phase, where nominal speed reaches 6000 rpm and nominal torque holds at 0.35 Nm. On single-phase 115 V or 230 V the nominal speed drops to 2000 rpm or 4000 rpm respectively, with torque at 0.5 Nm. If your cabinet only has single-phase, budget for the reduced top speed. ## Absolute single-turn SinCos Hiperface encoder — no homing cycle The absolute single-turn SinCos Hiperface encoder reports position at power-up without a reference run — the controller reads the absolute position from the SinCos tracks on the first communication cycle. Single-turn means the encoder tracks one mechanical revolution; multi-turn applications (spindles, long belts) need a multi-turn encoder variant. Peak stall torque hits 1.5 Nm across the 115-480 V three-phase range, drawing 2.9 A for up to 3 seconds — useful for breaking away a stuck load or accelerating through a short high-torque segment. The back EMF constant is 40 V/krpm at 20°C, so at 6000 rpm the motor generates 240 V line-to-line back EMF — the drive DC bus must stay above this to maintain current control. ## IP65, smooth shaft, rotatable connector — integration constraints The shaft is smooth (no keyway), so the coupling must grip by friction or use a set-screw hub; verify the coupling bore matches the 9 mm shaft diameter and 20 mm shaft length. The rotatable right-angled connector lets the cable exit in any of four orientations — useful when the motor sits in a tight corner and the cable needs to route away from moving parts. No holding brake is fitted on this variant; if the vertical axis must hold position when power drops, add an external brake or choose a SH3 variant with the brake option. Maximum radial force at the shaft nose derates with speed: 340 N at 1000 rpm down to 170 N at 8000 rpm. The maximum axial force is 40 N. If the load applies a belt tension or overhung load, check the radial force curve against the operating speed — exceeding it shortens bearing life.","metaTitle":"Schneider Electric SH30551P01A2100 Servo Motor, 290 W","metaDescription":"Schneider Electric SH30551P01A2100 SH3 servo motor, 290 W continuous, 55 mm flange, absolute single-turn SinCos Hiperface encoder, IP65.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH30551P01A2100","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, angular, IP65/65","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 6000 rpm 400 V three phase 6000 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":"rotatable right angled 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":"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/39458054e68cc072aa80970844b5552d.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH30551P01A2100/sh3-servomotor-55mm-1-stack-smooth-shaft-sincos-singleturn-128-no-brake-angular-ip65-65/"},"ai":{"faq":[{"question":"What encoder type does SH30551P01A2100 use?","answer":"The motor uses an absolute single-turn SinCos Hiperface encoder.
