Continuous power and where the SH3 frame sits
The Schneider Electric SH30552P0AA4000 is the SH3 short-frame servo at 55 mm flange, listed at 530 W continuous power and 280 W on a 230 V single-phase feed — so the same motor stretches roughly 1.9× in continuous power once it sees three-phase 400 V or 480 V instead of single-phase 230 V.
Speed, torque, and the supply-class envelope
Nominal speed tracks the supply: 4000 rpm at 230 V single-phase, 8000 rpm at 400 V three-phase, and 9000 rpm at 480 V three-phase — paired with nominal torque of 0.75 N.m on the single-phase feed and 0.63 N.m on both three-phase feeds. In plain terms, the same winding delivers more speed headroom on three-phase but trades roughly 16 % of nominal torque to get there. Peak stall torque is 2.5 N.m across the 115–480 V three-phase window, against a continuous stall torque of 0.71 N.m and continuous stall current of 1.2 A — so the motor has roughly 3.5× of stall torque available in transient bursts, bounded by the 4.8 A Irms peak ceiling. Maximum mechanical speed is 9000 rpm with a torque constant of 0.59 N.m/A at 120 °C and a back-EMF constant of 40 V/krpm at 20 °C — the back-EMF figure is what limits how close to top speed a 480 V drive can push the winding before the bus voltage runs out of headroom.
Feedback, connector, and the IP65 / IP54 split
Encoder type is the absolute single-turn Hiperface DSL — a one-cable feedback+digital interface that runs through a single quick-lock rotatable right-angled connector, so the cabinet-side wiring is just one hybrid lead back to the drive. IP degree of protection splits: IP65 on the motor body, IP54 on the shaft bushing when no shaft seal ring is fitted — which is the SH30552P0AA4000 configuration. The shaft bushing IP rating is the gap a junior on the floor needs to hear twice: dust and water spray hit the housing, but the shaft exit is the weaker point, and the seal ring upgrade is a separate order.
No holding brake on this build
Holding brake is listed as without, so the SH30552P0AA4000 ships without an internal fail-safe brake — a vertical axis that needs gravity-hold must source the brake externally or move to a braked variant in the same frame.
Mounting, shaft, and the load-side envelope
Mounting support is the international standard flange with a 40 mm centring collar at 2 mm depth and four 5.5 mm mounting holes, mating a smooth 9 mm shaft at 20 mm length — the bolt pattern is what lets the SH30552P0AA4000 drop onto common NEMA-style and IEC-style adapter plates without a custom bracket. Shaft load limits are 370 N radial at 1000 rpm and 40 N axial, with natural convection cooling and a 130 °C copper-hot thermal ceiling — so the continuous rating assumes still air, no shroud, and no heat-soaked coupling housing pushing the bearing temperature the wrong way.
