Nominal speed is 4000 rpm at 230 V single phase, 8000 rpm at 400 V three phase, and 9000 rpm at 480 V three phase, with a maximum mechanical speed of 9000 rpm — so the 480 V rail is the one that actually exercises the upper end of the speed envelope without hitting the ceiling. Continuous output power is 160 W at 230 V single phase and 290 W at 400 V and 480 V three phase, with 290 W also listed as the continuous power figure — so the three-phase rails deliver roughly 1.8× the single-phase continuous power at the same frame size. ## Torque, current, and the loop the drive has to close Peak stall torque is 1.5 N.m at 115 to 480 V three phase against a continuous stall torque of 0.42 N.m — so the motor can pull roughly 3.6× its continuous rating for short transients, which is the headroom acceleration reserves draw from. Maximum current Irms is 2.9 A and the 3-second peak output current is also 2.9 A, with a continuous stall current of 0.73 A — the drive sizing question is whether the servo amplifier can source 2.9 A Irms into a stator resistance of 41.8 Ohm with a 37.13 mH inductance, not whether it can hold the continuous stall figure. Torque constant is 0.58 N.m/A at 120 °C and back-EMF constant is 40 V/krpm at 20 °C — the standard Ki/Kv pair a controls engineer uses to back-calculate the current command from a demanded torque and to predict bus regeneration at top speed. ## Feedback and the cabling that won't fight the cycle time Encoder type is absolute single turn Hiperface DSL and the electrical connection is a rotatable right-angled quick-lock connector — DSL is a single-cable protocol carrying power and feedback on one pair, so the cabinet-side wiring collapses to one hybrid cable per axis and the distributed-clock skew question becomes a cable-length and shielding question rather than a second-connector question. The motor body carries IP65 per IEC 60034-5 and the shaft bushing without a shaft seal ring is IP54 — so the wet-side rating is IP65 on the housing but drops to IP54 where the shaft exits, which matters for washdown or food-grade skids where the seal stack is the wet barrier. ## Mechanical fit on the machine Shaft diameter is 9 mm with a 20 mm shaft length and a parallel key at 3 mm key width, maximum radial force Fr is 340 N at 1000 rpm and maximum axial force Fa is 40 N — the radial load figure falls as speed rises, so a belt drive or pinion mounted outboard of the bearing needs to be re-checked against the Fr curve at the operating speed, not at 1000 rpm. Cooling is natural convection and the temperature copper hot limit is 130 °C — no integrated fan, so cabinet airflow or a cold plate carries the thermal budget at the continuous stall point.","metaTitle":"Schneider Electric SH30551P1AA4000 servo motor, 0.5 N.m","metaDescription":"Schneider Electric SH30551P1AA4000 SH3 servo motor, 55 mm flange, 0.5 N.m nominal torque, Hiperface DSL encoder, IP65.
