{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"SH32051P12A2100","brand":"Schneider Electric","brandSlug":"schneider","productSlug":"SH32051P12A2100","canonicalUrl":"https://aoctrl.com/schneider/SH32051P12A2100","factsUrl":"https://aoctrl.com/api/mcp/products/SH32051P12A2100","rawCanonicalId":null},"summary":{"shortDescription":"Schneider Electric SH3 SH32051P12A2100 three-phase servo motor, 5500 W continuous, 400 V, 31.9 N.m nominal torque, 205 mm flange, IP65, Hiperface SinCos absolute multiturn encoder.","salesMarkdown":"The SH32051P12A2100 is a SH3-series three-phase servo motor rated 5500 W continuous at 400 V three phase, with a nominal torque envelope that follows the voltage tap: 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. On the 400 V three-phase rail — the operating point the drive sizing should anchor against — the motor delivers 5.5 kW with 17.5 N.m of continuous torque, which is the figure to use when matching the drive's continuous current to the mechanical load. Peak stall torque reaches 110 N.m across the full 115 to 480 V range, with a continuous stall of 36.9 N.m and an Irms peak of 87.2 A — the burst margin that determines whether the drive can accelerate the load through the worst-case cycle step without tripping on I²t. ## Speed points that define the drive profile Nominal speed is voltage-tapped rather than field-weakened: 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. In practice that means the same motor swings from 750 rpm to 3600 rpm simply by changing the supply rail — sizing the gear reducer and the drive's voltage class together is the real engineering decision, not picking a motor part number. Back-EMF constant is 104 V/krpm at 20 °C and torque constant is 1.75 N.m/A at 120 °C winding temperature; combined with stator resistance 0.3 Ohm and inductance 2.97 mH, these are the constants the drive's auto-tuning routine uses to lock the current loop to the rotor. ## Mechanical envelope: 205 mm flange, 38 mm shaft The motor mounts on an international standard flange with a 205 mm flange size, 180 mm centring collar, 14 mm mounting holes, and a 38 mm shaft diameter with an 80 mm shaft length and a 10 mm parallel key. Overall length is 321 mm — that's the dimension to budget against the machine frame when the motor drops into a replacement cut-out. Shaft loading is rated at 740 N maximum axial force and 3730 N radial at 1000 rpm, derating to 2580 N at 3000 rpm — the radial figure is the one that decides whether a belt drive, a pinion, or a direct coupling is the right coupling choice for the application. ## Feedback, sealing, and the field-side wiring Ingress is IP65 on both the motor body and the shaft bushing to IEC 60034-5; cooling is natural convection, no fan — meaning the thermal budget depends entirely on the mounting surface and any forced airflow the enclosure provides, and IP65 is enough for washdown-adjacent panels but not for direct spray zones.","metaTitle":"SH32051P12A2100 Servo Motor, 5500 W, 3-Phase","metaDescription":"SH32051P12A2100 SH3 series servo motor, 5500 W continuous at 400 V three phase, 31.9 N.m peak nominal torque, IP65, 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":"SH32051P12A2100","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 Multiturn 128, no Brake, angular, IP65/65","Encoder type":"Absolute multiturn 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":"Straight connector","Electrical connection":"rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"5.0","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":"$6,585.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/47841b82bf8dee72c99beea20d3bc8f8.pdf","sourceUrl":"https://www.se.com/us/en/product/SH32051P12A2100/sh3-servomotor-205mm-1-stack-keyed-shaft-sincos-multiturn-128-no-brake-angular-ip65-65/"},"ai":{"faq":[{"question":"What does the SH32051P12A2100 power curve look like across voltage taps?","answer":"Continuous output is 2510 W at 115 V single phase, 4240 W at 230 V single phase, 5500 W at 400 V three phase, and 5200 W at 480 V three phase, with nominal torque tracking 31.9 N.m down to 13.8 N.m across the same taps.
