Nominal torque depends on which bus the drive is running: 0.5 N.m at 230 V single phase drops to 0.35 N.m on both 400 V three phase and 480 V three phase rails — useful when the same axis is being evaluated against 230 V vs 400/480 V cabinet supplies. Nominal speed tracks the same rail split: 4000 rpm at 230 V single phase, 8000 rpm at 400 V three phase, and 9000 rpm at 480 V three phase; maximum mechanical speed is 9000 rpm. Continuous output power is 160 W at 230 V single phase and 290 W at both 400 V and 480 V three phase — the 230 V rail is the limiter for steady-state shaft work on this frame. ## Sizing headroom: peak stall, continuous stall, and current Peak stall torque is 1.5 N.m across 115 V to 480 V three phase, giving roughly 3× the nominal torque envelope as instantaneous overload headroom for acceleration phases — the drive's current limit, not the motor's thermal rating, is what defines how long that peak can be held. Continuous stall torque is 0.42 N.m at 115 V to 480 V three phase, with a continuous stall current of 0.73 A — so a thermally-constrained sizing point (zero rpm, holding a stationary load) sits below the nominal torque figure rather than at it. Maximum Irms and the 3-second peak output current both land at 2.9 A, which is the current ceiling a commissioning engineer should configure as the axis peak limit in the drive. The torque constant of 0.58 N.m/A at 120 °C and a back-EMF constant of 40 V/krpm at 20 °C give a clean 7.2 A·krpm/V ratio that drive autotune routines can use to cross-check the current-loop gain before the first move command. ## Feedback, brake, and shaft-side mechanics Feedback is an absolute multiturn Hiperface DSL encoder on a quick-lock rotatable right-angle connector — the single-cable DSL link keeps the cabinet wiring to one hybrid cord and lets the drive resolve absolute position without a battery box on the motor. The integrated holding brake pulls in at 10 W and delivers 0.8 N.m of holding torque — sized for vertical-axis static hold rather than dynamic stopping; for emergency-stop dynamic braking the drive's regen/absorber circuit still does the work. The shaft is 9 mm diameter, 20 mm long, smooth (no keyway), with a maximum radial force of 370 N at 1000 rpm and a maximum axial force of 40 N — both figures drop with speed and must be derated against the actual mounting distance per the shaft-load curve in the product drawing. ## Panel-side mounting and environment The motor is sealed to IP65 on both the motor body and the shaft bushing per IEC 60034-5, so it tolerates washdown and dusty cell-side mounting as long as the mating connector is seated and the shaft seal is intact. Cooling is natural convection with no integrated fan — for continuous-torque applications at the upper end of the rating, verify the motor's mounting flange is bonded to a thermally-conductive surface or heatsink to stay within the 130 °C copper-hot limit. Mechanical fit is an international-standard flange with a 40 mm centring collar at 2 mm depth and 5.5 mm mounting holes — drop-in compatible with the SH3 family footprint. ## Sourcing posture for the BOM line The part is recorded as current production by the manufacturer, with no official successor or cross-reference on the family record — the existing MPN stays the qualified BOM entry until the vendor announces otherwise.","metaTitle":"Schneider SH30551P0BF4100 Servo Motor, Brake, 0.5 N.m","metaDescription":"Schneider Electric SH30551P0BF4100 SH3 servo motor with brake, 0.5 N.m nominal at 230 V, 400 V / 480 V torque and speed data on record.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"SH30551P0BF4100","Length":"159 mm","Inertia":"0.021 kg.cm² of brake 0.059 kg.cm² of motor","Shaft end":"Smooth shaft","description":"SH3 servomotor, 55mm, 1 stack, smooth Shaft, Multiturn DSL 18bit, Brake, OneMotorCable angular M17, IP65/65","Encoder type":"Absolute multiturn Hiperface DSL","Shaft length":"20 mm","Holding brake":"With","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":"0.08 kg.cm²","Holding torque":"0.8 N.m","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":"1.35 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","Brake pull-in power":"10 W","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 IP65 shaft bushing: conforming to IEC 60034-5","Maximum radial force Fr":"370 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 x 4096 turns","[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/1ba5526f2c8e2e585881cc5d4b226b45.pdf","sourceUrl":"https://www.se.com/uk/en/product/SH30551P0BF4100/sh3-servomotor-55mm-1-stack-smooth-shaft-multiturn-dsl-18bit-brake-onemotorcable-angular-m17-ip65-65/"},"ai":{"faq":[{"question":"What is SH30551P0BF4100's listed length on the Servo Motors with Brake line?","answer":"Body length is 159 mm for SH30551P0BF4100 on the SH3 55 mm flange — the standard frame dimension for this rating in the family."},{"question":"What is SH30551P0BF4100's listed inertia on the Servo Motors with Brake line?","answer":"Total rotor inertia is 0.08 kg.cm², broken out as 0.021 kg.cm² for the brake and 0.059 kg.cm² for the bare motor.
