On 230 V single-phase the nominal speed drops to 2000 rpm, so the supply voltage at the cabinet dictates the usable speed range before any gearing. Nominal torque varies with supply: 7 N·m at 230 V single-phase, 5.7 N·m at 400 V three-phase, and 5.1 N·m at 480 V three-phase. The torque constant is 1.22 N·m/A measured at 120 °C copper temperature — the hot winding condition that governs continuous duty. ## Holding brake and vertical-axis safety For a machine tool or pick-and-place cell, the brake engages when the drive enable drops — the 9 N·m rating must exceed the reflected load torque at the motor shaft, including any overhung load from a timing-belt pulley. ## Encoder feedback and position retention The absolute multiturn Hiperface DSL encoder reports position on power-up without a homing cycle — critical for multi-axis coordinated motion where each axis must know its absolute position after a power cycle. The DSL protocol runs over a single cable pair, reducing cabling in the drag chain. ## IP rating and shaft seal reality The motor body is IP65 per IEC 60034-5, meaning it withstands hose-directed water and dust ingress. The shaft bushing without a shaft seal ring is only IP54 — if the application sees direct spray on the shaft exit (e.g., washdown zones), an optional shaft seal ring is needed to maintain the IP65 boundary at the bushing. ## Peak and continuous torque capability Peak stall torque is 28.3 N·m at 115–480 V three-phase, available for 3 seconds — this handles acceleration transients and emergency stops. Continuous stall torque is 8 N·m across the same voltage range, which sets the thermal limit for holding position under load without airflow. Continuous output power is 2400 W; nominal output power at 400 V three-phase is 2390 W — the motor runs near its continuous rating at the rated speed/torque point. Natural convection cooling means no fan noise or filter maintenance, but the thermal budget is fixed by the housing surface area. ## Mechanical interface and mounting The motor mounts on an international standard flange with a 100 mm flange size and 9.0 mm mounting holes. The smooth shaft is 19 mm diameter, 40 mm long, with a centring collar depth of 3.5 mm — standard for a direct coupling or timing-belt pulley with a keyless clamp. Overall length is 271.5 mm — check the available envelope in the machine frame, especially if the motor mounts vertically and the cable exit (straight connector or quicklock rotatable right-angled connector) must clear adjacent structure. ## Electrical parameters for drive matching Stator resistance is 1.43 Ω and inductance is 4.7 mH — these set the electrical time constant and influence the current-loop tuning on the servo drive. Back EMF constant is 77 V/krpm at 20 °C, which determines the bus voltage needed to reach rated speed against the motor's own voltage drop. Maximum RMS current is 28.3 A — the drive must be rated for at least this continuous current, and the peak current (also 28.3 A for 3 s) matches the drive's peak rating. The 4-pole motor runs at 2000–4800 rpm depending on supply; the drive's velocity loop bandwidth should be set for the pole count. ## Radial and axial load limits Maximum radial force at the shaft centre is 3570 N at 2000 rpm, dropping to 3120 N at 3000 rpm, and further to 130 N at 1000 rpm — the bearing life is inversely related to radial load, so a belt-driven load must be sized within these limits at the operating speed. Maximum axial force is 20 N, typical for a direct-coupled load with no thrust.","metaTitle":"Schneider SH31003P0BF4000 Servo Motor with Brake, 2400 W","metaDescription":"Schneider Electric SH31003P0BF4000 servo motor with holding brake, 2400 W continuous, 28.3 A peak, IP65, absolute multiturn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31003P0BF4000","Length":"10.7 in (271.5 mm)","Inertia":"0.618 kg.cm² of brake 3.22 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 100mm, 3 stacks, smooth Shaft, Multiturn DSL 18bit, Brake, OneMotorCable angular M23, IP54/65","Encoder type":"Absolute multiturn Hiperface DSL","Shaft length":"1.6 in (40 mm)","Holding brake":"With","Nominal speed":"2000 rpm 230 V single phase 4000 rpm 400 V three phase 4800 rpm 480 V three phase","Rotor inertia":"3.838 kg.cm²","Holding torque":"79.7 lbf.in (9 N.m)","Nominal torque":"62.0 lbf.in (7 N.m) 230 V single phase 50.4 lbf.in (5.7 N.m) 400 V three phase 45.1 lbf.in (5.1 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.22 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2400 W","Mounting Support":"International standard flange","Sizing reference":"SH31003P","Back emf constant":"77 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"250.5 lbf.in (28.3 N.m) 115...480 V three phase","Stator inductance":"4.7 mH","Stator resistance":"1.43 Ohm","Brake pull-in power":"18 W","Maximum current Irms":"28.3 A","Nominal output power":"1470 W 230 V single phase 2390 W 400 V three phase 2390 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"quicklock rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"4.0","Maximum axial force Fa":"20 N","Output current 3s peak":"28.3 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"70.8 lbf.in (8 N.m) 115...480 V three phase","IP degree of protection":"IP65 motor: conforming to IEC 60034-5 IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5","Maximum radial force Fr":"3570 N 2000 rpm 3120 N 3000 rpm 130 N 1000 rpm 105 N 2000 rpm 90 N 3000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"6.6 A","Maximum mechanical speed":"6000 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":"4.5 in (115 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7ecec9acce38f9cb69c8dbe4331ba574.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH31003P0BF4000/sh3-servomotor-100mm-3-stacks-smooth-shaft-multiturn-dsl-18bit-brake-onemotorcable-angular-m23-ip54-65/"},"ai":{"faq":[{"question":"What is the holding brake torque on this servo motor?","answer":"The holding brake delivers 9 N·m static holding torque, with a pull-in power of 18 W.
