Motor ratings and encoder feedback
The SH30551P11A1000 is a 290 W continuous-power servo motor from the Schneider Electric SH3 series, delivering a nominal torque of 0.5 N·m on single-phase supplies and 0.35 N·m on three-phase 400/480 V lines. Speed capability spans 2000 rpm on 115 V single-phase up to 8000 rpm on 400/480 V three-phase, with an absolute single-turn SinCos Hiperface encoder providing position feedback without requiring a home cycle on power-up.
Mounting and environmental sealing
Mounts via an international standard flange with a 55 mm flange size and 40 mm centring collar — the 5.5 mm mounting holes and 2 mm centring collar depth align with standard servo interfaces. IP65 protection with the shaft bushing seal ring fitted means the motor body withstands washdown environments common in food processing or packaging lines; without the shaft seal ring it drops to IP54.
Electrical connection and thermal limits
The motor offers both a rotatable right-angled connector and a straight connector option — the rotatable version simplifies cable routing in tight cabinet panels where the motor orientation is fixed. Stator resistance is 41.8 Ω and inductance is 108.72 mH; the torque constant is 0.58 N·m/A at 120 °C copper temperature, with a peak stall torque of 1.5 N·m available for short-duration acceleration moves. Continuous stall current is 0.73 A, and the maximum RMS current is 2.9 A — the 3-second peak current matches the same 2.9 A figure, so the drive's current limit should be set at or below this value to avoid winding overheating.
Sourcing and lifecycle status
The sizing reference is SH30551P, which anchors this motor within the broader SH3 family; no pin-compatible direct replacement is recorded, so a BOM change would require a full motor re-selection.
