Singleturn absolute means the position is absolute within one electrical revolution; after a power cycle the drive knows shaft angle immediately without a homing run, but it does not retain position across multiple turns. At 18 bits that is 262144 counts per revolution, which sets the position loop resolution the drive can achieve. The encoder rating is IP65 on the motor body, same as the shaft bushing. ## Torque and speed across the three voltage classes The motor produces different nominal torque depending on supply voltage and phase count: 1.1 N.m nominal at 230 V single-phase drops to 0.81 N.m at both 400 V and 480 V three-phase — the lower torque at the higher voltages reflects the motor being wound for the 400/480 V class with a corresponding increase in speed. Nominal speed scales from 4000 rpm to 8000 rpm to 9000 rpm across the same three conditions. Continuous stall torque is 1.05 N.m across the full 115–480 V three-phase range, and peak stall torque is 3.5 N.m for up to 3 seconds at any voltage in that band — a 3.3:1 peak-to-continuous ratio that defines the short-term overload budget available during acceleration. ## IP65 and natural convection in the deployment context IP65 on both the motor body and shaft bushing (conforming to IEC 60034-5) means the housing is dust-tight and protected against water jets — the shaft bushing seal is the critical point for encoder and bearing longevity in washdown or dusty environments. Natural convection cooling means the motor does not have a fan; thermal performance is entirely passive, so the 130 °C copper hot temperature limit and the 680 W continuous power rating assume adequate airflow around the housing. The 55 mm square flange and 203 mm stack length define the mounting envelope in the panel or machine frame. ## Current and power sizing for drive selection The maximum RMS current is 6.5 A, which is also the 3-second peak current rating — the drive must be sized to supply at least that current without voltage collapse during acceleration. The sizing reference in the data is SH30553P, which ties this motor to the Schneider Lexium or similar SH3-compatible drive family for parameter auto-tune. Stator resistance of 10.4 Ohm and inductance of 13.02 mH set the electrical time constant the drive uses to tune current regulation loops. Back EMF constant is 41 V/krpm at 20 °C, which determines the generated voltage the drive must handle when decelerating a spinning load back into the drive's DC bus.","metaTitle":"SH30553P1AF4100 Schneider SH3 Servo Motor, 55mm, IP65, Brake","metaDescription":"Schneider Electric SH3 servo motor with integrated holding brake, 0.8 N.m brake torque, 680 W continuous power, IP65, 55mm flange.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"SH30553P1AF4100","Length":"203 mm","Inertia":"0.021 kg.cm² of brake 0.134 kg.cm² of motor","Key width":"3 mm","Shaft end":"Parallel key","description":"SH3 servomotor, 55mm, 3 stacks, keyed Shaft, Singleturn DSL 18bit, Brake, OneMotorCable angular M17, IP65/65","Encoder type":"Absolute single turn Hiperface DSL","Shaft length":"20 mm","Holding brake":"With","Nominal speed":"4000 rpm at 230 V single phase 8000 rpm at 400 V three phase 9000 rpm at 480 V three phase","Rotor inertia":"0.155 kg.cm²","Holding torque":"0.8 N.m","Nominal torque":"1.1 N.m at 230 V single phase 0.81 N.m at 400 V three phase 0.81 N.m at 480 V three phase","Product weight":"1.95 kg","Shaft diameter":"9 mm","Torque constant":"0.62 N.m/A at 120 °C","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"680 W","Mounting support":"International standard flange","Sizing reference":"SH30553P","Back emf constant":"41 V/krpm at 20 °C","Device short name":"SH3","Motor flange size":"55 mm","Peak stall torque":"3.5 N.m at 115...480 V three phase","Stator inductance":"13.02 mH","Stator resistance":"10.4 Ohm","Brake pull-in power":"10 W","Maximum current Irms":"6.5 A","Nominal output power":"390 W at 230 V single phase 680 W at 400 V three phase 680 W at 480 V three phase","Centring collar depth":"2 mm","Electrical connection":"quicklock rotatable right angled connector","Number of motor poles":"3.0","Maximum axial force Fa":"80 N","Output current 3s peak":"6.5 A","Temperature copper hot":"130 °C","Continuous stall torque":"1.05 N.m at 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":"710 N at 1000 rpm","Mounting holes diameter":"5.5 mm","Centring collar diameter":"40 mm","Continuous stall current":"1.7 A","Maximum mechanical speed":"9000 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":"63 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0db6e678eaec0ccb28cfa59b20e2c87b.pdf","sourceUrl":"https://www.se.com/uk/en/product/SH30553P1AF4100/sh3-servomotor-55mm-3-stacks-keyed-shaft-singleturn-dsl-18bit-brake-onemotorcable-angular-m17-ip65-65/"},"ai":{"faq":[{"question":"What is the closest alternative to SH30553P1AF4100 in this servo family?","answer":"The data does not carry a documented pin-compatible or mechanically equivalent peer MPN for cross-reference.
