Nominal speed hits 3000 rpm on 230 V single-phase, 6000 rpm on 400 V three-phase, and 7200 rpm on 480 V three-phase — the motor's speed range is supply-voltage dependent, not a single fixed rating. Peak stall torque reaches 11.3 N.m across the 115...480 V three-phase range, and continuous stall torque is 2.94 N.m — the peak figure governs acceleration and emergency stop profiles, while the continuous stall sets the holding limit for dwell periods. ## Brake and encoder — what they mean for the axis The holding brake delivers 3 N.m static holding torque — sufficient to hold a vertical load at standstill without the drive maintaining current, but it is a holding brake, not a dynamic braking resistor; the drive's deceleration ramp must keep the DC bus below the overvoltage threshold during fast stops. Brake pull-in power is 7 W — a small load on the 24 VDC control supply, but the brake release time and the drive's enable sequence must be coordinated to prevent the axis from dropping before the motor develops torque. The absolute single-turn Hiperface DSL encoder eliminates the need for a homing sequence on power-up — the position is known immediately, which cuts cycle time on machines that power-cycle between batches. ## Mechanical interface and mounting constraints Flange size is 70 mm (IEC standard), shaft diameter 14 mm with a parallel key and 30 mm shaft length — the mounting footprint matches the SH3 frame, so a swap into an existing SH3 installation requires no bracket rework. Overall length is 246 mm (9.7 in) — this is the body length excluding the connector protrusion; the straight connector and the optional quicklock rotatable right-angled connector add different overhang, so cable routing clearance must be checked against the panel depth. IP65 on the motor body per IEC 60034-5, but the shaft bushing without the shaft seal ring drops to IP54 — if the application sees directed washdown, the optional shaft seal ring must be specified to maintain IP65 at the shaft exit. Maximum radial force is 1050 N at 1000 rpm, and maximum axial force is 160 N — these set the belt-tension and coupling-load limits; exceeding them shortens bearing life and can cause the encoder to lose position tracking. ## Electrical parameters for drive tuning Stator resistance is 2.7 Ohm and stator inductance is 7.3 mH — these feed the auto-tuning routine in the drive; the motor's electrical time constant (L/R) is about 2.7 ms, which sets the current-loop bandwidth ceiling. Torque constant is 0.72 N.m/A at 120 °C copper temperature, and the back EMF constant is 49 V/krpm at 20 °C — the back EMF rises with motor speed and must stay below the drive's DC bus voltage to maintain current regulation at high speed. Maximum current Irms is 17.0 A, and the 3-second peak output current is also 17.0 A — the motor's thermal limit is the continuous current at rated torque, not the peak; the drive's current limit should be set to the motor's continuous rating for sustained operation. No minimum order quantity is stated — single-unit and production volumes are both quotable. The sizing reference SH30703P ties this motor to the SH3 frame family — if the project needs a different torque or speed point, the SH3 series offers variants within the same flange and shaft dimensions, but no direct pin-compatible alternative is listed for this exact order code.","metaTitle":"Schneider Electric SH30703P1AF4000 Servo Motor with Brake","metaDescription":"Schneider Electric SH30703P1AF4000 SH3 servo motor with holding brake, 1.33 kW continuous power, 3000 rpm nominal speed, IP65, absolute single-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH30703P1AF4000","Length":"9.7 in (246 mm)","Inertia":"0.227 kg.cm² of brake 0.58 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.2 in (5 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 70mm, 3 stacks, keyed Shaft, Singleturn DSL 18bit, Brake, OneMotorCable angular M23, IP54/65","Encoder type":"Absolute single turn Hiperface DSL","Shaft length":"1.2 in (30 mm)","Holding brake":"With","Nominal speed":"3000 rpm 230 V single phase 6000 rpm 400 V three phase 7200 rpm 480 V three phase","Rotor inertia":"0.807 kg.cm²","Holding torque":"26.6 lbf.in (3 N.m)","Nominal torque":"24.8 lbf.in (2.8 N.m) 230 V single phase 18.6 lbf.in (2.1 N.m) 400 V three phase 18.6 lbf.in (2.1 N.m) 480 V three phase","Shaft diameter":"0.6 in (14 mm)","Torque constant":"0.72 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1330 W","Mounting Support":"International standard flange","Sizing reference":"SH30703P","Back emf constant":"49 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"2.8 in (70 mm)","Peak stall torque":"100.01 lbf.in (11.3 N.m) 115...480 V three phase","Stator inductance":"7.3 mH","Stator resistance":"2.7 Ohm","Brake pull-in power":"7 W","Maximum current Irms":"17.0 A","Nominal output power":"830 W 230 V single phase 1330 W 400 V three phase 1330 W 480 V three phase","Centring collar depth":"0.10 in (2.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"quicklock rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"3.0","Maximum axial force Fa":"160 N","Output current 3s peak":"17.0 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"26.02 lbf.in (2.94 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":"1050 N 1000 rpm","Mounting holes diameter":"0.2 in (5.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Continuous stall current":"4.1 A","Maximum mechanical speed":"8000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"262144 points/turn","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"3.2 in (82 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,543.86","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b4d804b21691d223cd151478db8bc216.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH30703P1AF4000/sh3-servomotor-70mm-3-stacks-keyed-shaft-singleturn-dsl-18bit-brake-onemotorcable-angular-m23-ip54-65/"},"ai":{"faq":[{"question":"What is the nominal torque of SH30703P1AF4000 at 400 V three-phase?","answer":"Nominal torque is 2.1 N.m at 400 V three-phase, compared to 2.8 N.m on 230 V single-phase.
