Nominal torque inverts that picture — 0.5 N·m at 230 V single phase drops to 0.35 N·m at both 400 V and 480 V three phase, so the higher-rail operation trades torque for top-end speed. Continuous output power lands at 160 W at 230 V single phase and 290 W at both 400 V and 480 V three phase; the peak stall torque is 1.5 N·m across the 115…480 V three-phase range, against a continuous stall of 0.42 N·m at 0.73 A. The maximum Irms and 3-second peak output current are both 2.9 A, so a drive set above that envelope hits current-limit before it hits torque-limit. Back EMF constant is 40 V/krpm at 20 °C and torque constant 0.58 N·m/A at 120 °C — these two numbers are how the drive is commissioned, because a mismatched constant on the motor nameplate turns into a torque-ripple or following-error fault on first move. ## Mechanical envelope and panel-side fit The 132.5 mm body fits the standard SH3 footprint on a 40 mm centring collar with four 5.5 mm mounting holes on an international standard flange — that's the panel builder's mating footprint, and it aligns with the SH3 family drill pattern. The smooth shaft is 9 mm in diameter over a 20 mm length, so a coupling or pulley selection must respect those dimensions rather than a keyed shaft pattern. Thrust limits are 40 N axial and 370 N radial at 1000 rpm, the latter dropping with rpm per the standard derating — a belt-driven application needs the tension budgeted inside that envelope or the bearing life collapses. The rotatable right-angle quicklock connector lets the cable exit be set after the motor is bolted down, which matters when the cabinet layout forces a side or top entry. ## Procurement posture — active frame, sourced to order No stock-holding claim and no lead-time number on the page; the buying decision closes when the RFQ returns.","metaTitle":"SH30551P0BA4100 Schneider SH3 Servo Motor, 290 W","metaDescription":"Schneider Electric SH30551P0BA4100 SH3 servo motor, 55 mm flange, 290 W continuous, Hiperface DSL absolute multiturn encoder.
