55 mm flange, 680 W continuous — what this SH3 frame actually delivers
The Schneider Electric SH30553P0AA4100 is an SH3-series three-phase servo motor (Device short name SH3, Sizing reference SH30553P) with a 55 mm flange and international standard mounting, dropping into a typical small-frame servo pocket on a packaging line, indexing table, or pick-and-place axis where the existing machine footprint already calls for an SH30553 family drop-in. Continuous output runs 680 W with a 1.05 N.m continuous stall torque from 1.7 A; peak stall torque reaches 3.5 N.m at 6.5 A Irms (3-second peak), so the drive sizing budget should be set against the peak, not the continuous figure.
Three supply windows on one nameplate — speed and torque vs. bus voltage
Nominal speed is 4000 rpm on 230 V single-phase, 8000 rpm on 400 V three-phase, and 9000 rpm on 480 V three-phase, with nominal torque of 1.1 N.m (230 V single-phase) or 0.81 N.m (400 V / 480 V three-phase) and nominal output power of 390 W single-phase versus 680 W on either three-phase bus — the three-phase connection is what unlocks the full 680 W continuous rating. Mechanical ceiling is 9000 rpm; torque constant is 0.62 N.m/A at 120 °C winding temperature, and back-EMF is 41 V/krpm at 20 °C, so the drive current loop must be tuned against the 0.62 N.m/A figure at the operating winding temperature, not at cold start.
Hiperface DSL feedback and the rotatable connector
Feedback is an absolute single-turn Hiperface DSL encoder — the single-cable DSL link carries power and position data on one pair, so the cabinet side needs a DSL-capable drive (Lexium 32 / Lexium 28S-class) and the existing SH30553-family harness lands without a separate encoder cable run. The electrical connection is a quicklock rotatable right-angled connector, which means the cable exit can be clocked to four positions before the lock is engaged — useful when the motor is mounted at an angle in a tight axis envelope and the harness has to follow the cable tray rather than the motor face.
Shaft, thrust loads, and the IP65 envelope
IP65 protection applies to both the motor body and the shaft bushing per IEC 60034-5, which clears washdown and food-adjacent packaging environments as long as the cable gland and connector face are sealed to the same standard; cooling is natural convection, so derating kicks in above the 130 °C winding hot-spot limit if the motor is enclosed in a heat-soaked cabinet.
