Nominal torque depends on the supply: 9.5 N.m at 230 V single phase, 7.9 N.m at 400 V three phase, and 6.9 N.m at 480 V three phase — so the same motor body covers a range of line voltages, but the torque you get changes with the input. Peak stall torque hits 40.5 N.m across the 115–480 V three-phase range, which tells you the short-term acceleration headroom for rapid moves. The integrated holding brake delivers 12 N.m static torque — enough to hold a vertical axis load at rest without the drive having to maintain current. Brake pull-in power is 18 W, so the DC bus or external 24 V supply needs to budget that draw when the brake releases. ## Encoder and feedback — absolute position without a home cycle The encoder is an absolute multiturn Hiperface DSL type. That means the motor knows its shaft position and the number of full revolutions from power-up — no homing routine needed after a power cycle or a controlled stop. The DSL (Digital Serial Link) protocol runs over a single cable pair, sharing power and data, which simplifies the feedback cable run back to the drive. The torque constant is 1.62 N.m/A at 120 °C winding temperature, and the back EMF constant is 103 V/krpm at 20 °C. These two numbers let you calculate the drive current needed for a given torque and the voltage headroom required at top speed. Stator resistance is 1.8 Ω and inductance is 13 mH — typical for a 2.5 kW frame, and the drive's current loop tuning will need those values for proper PI gains. ## Mounting, cooling, and environmental sealing The motor uses an international standard flange with a 100 mm square pilot diameter and a 95 mm centring collar. Four mounting holes at 9.0 mm diameter on the flange face — standard bolt pattern for this frame size. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and an 8 mm key width. Centring collar depth is 3.5 mm, so the pilot registers positively into the mating bore before the bolts take the load. Cooling is by natural convection — no external fan or forced air. That means the continuous torque ratings assume free airflow around the motor body; mounting it in a confined space or against a heat source will require derating. Electrical connection is via a rotatable right-angled connector and a quick-lock straight connector — both are supplied, so you can orient the cable exit to suit the installation. The connector arrangement mates with the standard Hiperface DSL cable sets from Schneider's Lexium range. The sizing reference is SH31004P, which is the base motor frame without the brake or connector options. The full order code SH31004P1BF3100 encodes the brake (B), the connector variant (F), and the encoder type (3100 for Hiperface DSL). If you already have a drive from the Lexium 28 or Lexium 32 family, the motor parameters are pre-loaded in the drive firmware — just enter the sizing reference and the drive auto-configures the current loop and encoder settings.","metaTitle":"Schneider Electric SH31004P1BF3100 Servo Motor with Brake","metaDescription":"Schneider Electric SH31004P1BF3100 servo motor with brake, 2.5 kW continuous power, 12 N.m holding torque, IP65, absolute multiturn Hiperface DSL encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"12.1 in (307.5 mm)","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn Hiperface DSL","Shaft length":"2.0 in (50 mm)","Holding brake":"With","Nominal speed":"1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"5.245 kg.cm²","Holding torque":"106.2 lbf.in (12 N.m)","Nominal torque":"84.08 lbf.in (9.5 N.m) 230 V single phase 69.9 lbf.in (7.9 N.m) 400 V three phase 61.07 lbf.in (6.9 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.62 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2500 W","Mounting Support":"International standard flange","Sizing reference":"SH31004P","Back emf constant":"103 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"358.5 lbf.in (40.5 N.m) 115...480 V three phase","Stator inductance":"13 mH","Stator resistance":"1.8 Ohm","Brake pull-in power":"18 W","Maximum current Irms":"32.3 A","Nominal output power":"1490 W 230 V single phase 2480 W 400 V three phase 2480 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"quicklock straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"4","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"88.5 lbf.in (10 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","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"6.2 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/949b014bcf3b50d95c107ab105a36463.pdf","sourceUrl":"https://www.se.com/be/en/product/SH31004P1BF3100/sh3-servomotor-100mm-4-stacks-keyed-shaft-multiturn-dsl-18bit-brake-onemotorcable-straight-m23-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31004P1BF3100/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and speed does this motor need?","answer":"It is a three-phase motor.
