Continuous power is 290 W across the three-phase 400 V and 480 V rails and 160 W on 230 V single-phase, so a single BOM line covers the common European 400 V and North American 480 V cabinet supplies without a derate step. Nominal torque tracks the supply: 0.5 N.m at 230 V single phase, dropping to 0.35 N.m at 400 V and 480 V three phase. ## Speed envelope and overload headroom Nominal speed rises with the bus voltage: 4000 rpm at 230 V single phase, 8000 rpm at 400 V three phase, and 9000 rpm at 480 V three phase. Peak stall torque is 1.5 N.m across the 115–480 V three-phase range, roughly 4× the 0.35 N.m nominal at 400/480 V — enough margin for the short acceleration bursts typical of indexing and pick-and-place duty before the drive's current foldback engages. Maximum current is 2.9 A Irms with a 3-second peak of 2.9 A and continuous stall current 0.73 A, giving the drive sizing math a clean ratio: the drive's continuous output rating must hold at least 0.73 A per axis at stall and survive 2.9 A peaks for the worst-case accel/decel segment. Stator resistance 41.8 Ohm and inductance 37.13 mH shape the current-loop bandwidth the drive will tune to — the high resistance-to-inductance ratio points to a current loop that closes fast, useful for low-inductance servo drives that sample at 8–16 kHz. Torque constant 0.58 N.m/A at 120 °C and back-EMF constant 40 V/krpm at 20 °C keep the torque-per-amp and volts-per-krpm math inside the normal SH3 window. ## Mechanical envelope, shaft loads, and IP65 sealing Body length is 159 mm with a 55 mm flange, 40 mm centring collar (2 mm depth), and four 5.5 mm mounting holes on the international standard flange — drop-in for the SH3 family footprint. Shaft is 9 mm diameter with a 20 mm length and parallel key (3 mm key width), the standard SH3 small-frame keyed interface. IP65 on both the motor body and shaft bushing per IEC 60034-5 means the SH30551P1BF4100 holds up to low-pressure washdown and dust ingress — food-adjacent lines, outdoor cabinets, and machine-tool environments with cutting fluid mist are inside the envelope. Cooling is natural convection (no fan), so there is no fan filter to maintain and no fan-induced vibration on the shaft. ## Thermal envelope and continuous stall Continuous stall torque is 0.42 N.m across the 115–480 V three-phase range with a 130 °C winding hot-spot ceiling — the drive's thermal model should clamp continuous torque below 0.42 N.m at zero speed with the motor mounted to a surface that does not throttle the natural-convection path. The hot-spot figure is conservative for the SH3 family and aligns with standard Class B insulation practice.","metaTitle":"Schneider Electric SH30551P1BF4100 Servo Motor, 290 W, brake","metaDescription":"Schneider Electric SH30551P1BF4100 SH3 servo motor with brake, 290 W continuous, IP65, Hiperface DSL encoder.
