Its continuous-stall envelope is 0.42 N.m at 115...480 V three phase, with a peak stall of 1.5 N.m and 2.9 A Irms — meaning the drive can be sized for short surge moves (index, clamp, pick-and-place) without oversizing the continuous rating. ## Speed, torque and the three supply rails The motor's nameplate is shaped by which supply rail it sees. At 230 V single phase it delivers 0.5 N.m nominal at 4000 rpm and 160 W continuous; at 400 V three phase and 480 V three phase the speed ceiling climbs to 8000 rpm and 9000 rpm respectively while nominal torque settles at 0.35 N.m and continuous power rises to 290 W. That asymmetric envelope — more torque low-end, more speed top-end — is what decides whether to run it from a single-phase 230 V drive or a 400/480 V three-phase Lexium. Commissioning on the wrong rail underdelivers continuous torque, not peak. Back EMF constant is 40 V/krpm at 20 °C and stator resistance is 41.8 Ohm — high-impedance windings that pair naturally with compact servo amplifiers rather than the high-current drives built for bigger frame sizes. ## Feedback, brake and the connector on the back Encoder is absolute single-turn Hiperface DSL on a rotatable right-angled quicklock connector — a one-cable feedback link that the matching Lexium drive negotiates on first power-up. No separate encoder cable to dress through the cable chain. ## Shaft loads and mechanical envelope Shaft is 9 mm diameter with a parallel key (3 mm key width) and 20 mm usable length. Maximum radial load is 340 N at 1000 rpm, dropping as speed rises; maximum axial load is 40 N. Mounting is a 55 mm flange with 5.5 mm bolt holes on a 40 mm centring collar — a standard SH3 footprint. The motor is naturally cooled (no fan), so derating begins above the 130 °C copper-hot limit; cabinet airflow or a heat sink on the flange is the usual way to claw back continuous torque in a sealed enclosure. ## Ingress and ambient rating The motor body and shaft bushing are both IP65 to IEC 60034-5, meaning the body resists water jets and the shaft seal keeps washdown off the bearings — suitable for food-adjacent lines and outdoor mounting under a hood, though not for sustained submersion. ## Sourcing posture for the SH30551P1AF4100 No official successor order code appears on the SH30551P1AF4100 record — if this is a drop-in for a retired line, the same 55 mm flange and SH3 series footprint generally accepts a later SH3 variant, but the suffix code is what governs whether the encoder protocol, brake voltage and connector keying carry over without rework. Pricing and availability for the SH30551P1AF4100 are confirmed at quote time against the BOM quantity — sourced per RFQ through independent distribution rather than off-the-shelf shelf stock, so lead time and quantity breaks move with the production slot.","metaTitle":"Schneider SH30551P1AF4100 Servo Motor, 55mm flange, 290 W","metaDescription":"Schneider SH30551P1AF4100 SH3 servo motor with brake, 55 mm flange, 0.5 N.m nominal at 230 V single phase, IP65, Hiperface DSL.
