The shaft length is 3.1 in (80 mm). Mounting uses an international standard flange with flange size 8.07 in (205 mm), centring collar diameter 7.09 in (180 mm), and centring collar depth 0.2 in (4 mm). Four mounting holes at 0.6 in (14 mm) diameter. ## Torque and speed across supply voltages — the real operating envelope This is a three-phase servo motor with 5 poles. Nominal speed depends on supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. Nominal torque also varies: 31.9 N·m at 115 V single-phase, 27 N·m at 230 V single-phase, 17.5 N·m at 400 V three-phase, and 13.8 N·m at 480 V three-phase. Continuous power at 400 V three-phase is 5500 W. Continuous stall torque is 36.9 N·m across the 115...480 V three-phase range. Peak stall torque reaches 110 N·m across the same voltage range — that's the short-term overload capability for acceleration or deceleration. Maximum current Irms is 87.2 A, and the output current 3s peak is also 87.2 A — the peak current limit matches the maximum continuous current, so the motor's thermal limit is the binding constraint during overloads. ## Encoder, feedback, and electrical connection The encoder is an absolute single-turn SinCos Hiperface type — this gives position feedback at power-up without a homing cycle, and the SinCos analog track provides velocity ripple below what incremental encoders deliver. Electrical connection options: a rotatable right-angled connector or a straight connector — choose based on cable exit direction in the cabinet. IP65 protection on both the motor body and the shaft bushing, conforming to IEC 60034-5. Stator resistance is 0.3 Ω and stator inductance is 2.97 mH — these set the electrical time constant and influence the servo drive's tuning gains. Torque constant is 1.75 N·m/A at 120 °C copper temperature; back EMF constant is 104 V/krpm at 20 °C. ## Bearing loads and thermal limits Maximum radial force Fr depends on speed: 3730 N at 1000 rpm, 2960 N at 2000 rpm, and 2580 N at 3000 rpm. Maximum axial force Fa is 740 N. These are the limits for belt-drive or direct-coupling applications — overshoot them and bearing life drops sharply. Hot-spot copper temperature is rated at 130 °C — the winding insulation class supports this continuous temperature. Natural convection cooling means the motor relies on its own surface area to dissipate heat; derate if mounted in a confined space or near heat sources. Sourced through independent distribution channels. The sizing reference is SH32051P; the device short name is SH3.","metaTitle":"SH32051P11A1100 servo motor, 5.5 kW, 3000 rpm, 31.9 Nm, IP65","metaDescription":"SH32051P11A1100 servo motor, 5.5 kW at 400 V three-phase, 3000 rpm, 31.9 Nm nominal torque, IP65, absolute Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH32051P11A1100","Length":"12.6 in (321 mm)","Inertia":"0.0 kg.cm² of brake 71.4 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.4 in (10 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 205mm, 1 stack, keyed Shaft, SinCos Singleturn 128, no Brake, straight, IP65/65","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"3.1 in (80 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"71.4 kg.cm²","Nominal torque":"282.3 lbf.in (31.9 N.m) 115 V single phase 239.0 lbf.in (27 N.m) 230 V single phase 154.9 lbf.in (17.5 N.m) 400 V three phase 122.1 lbf.in (13.8 N.m) 480 V three phase","Shaft diameter":"1.5 in (38 mm)","Torque constant":"1.75 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"5500 W","Mounting Support":"International standard flange","Sizing reference":"SH32051P","Back emf constant":"104 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"8.07 in (205 mm)","Peak stall torque":"973.6 lbf.in (110 N.m) 115...480 V three phase","Stator inductance":"2.97 mH","Stator resistance":"0.3 Ohm","Maximum current Irms":"87.2 A","Nominal output power":"2510 W 115 V single phase 4240 W 230 V single phase 5500 W 400 V three phase 5200 W 480 V three phase","Centring collar depth":"0.2 in (4 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"5","Maximum axial force Fa":"740 N","Output current 3s peak":"87.2 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"326.6 lbf.in (36.9 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":"3730 N 1000 rpm 2960 N 2000 rpm 2580 N 3000 rpm","Mounting holes diameter":"0.6 in (14 mm)","Centring collar diameter":"7.09 in (180 mm)","Continuous stall current":"21 A","Maximum mechanical speed":"3800 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":"8.5 in (215 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6,135.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/47841b82bf8dee72c99beea20d3bc8f8.pdf","sourceUrl":"https://www.se.com/us/en/product/SH32051P11A1100/sh3-servomotor-205mm-1-stack-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-65/"},"ai":{"faq":[{"question":"What is the nominal torque and speed at 400 V three-phase for SH32051P11A1100?","answer":"At 400 V three-phase, nominal torque is 17.5 N·m and nominal speed is 3000 rpm.
