What's on the nameplate
The Schneider Electric SH30553P0BA4000 is the SH3 family servo motor, 55 mm flange, sizing reference SH30553P — an international-standard flange mount with a smooth 9 mm shaft and a Hiperface DSL absolute multiturn encoder on a quicklock rotatable right-angle connector. Continuous output lands at 680 W at 400 V three-phase and 680 W at 480 V three-phase, dropping to 390 W at 230 V single phase — the three-phase rail is where this frame earns its rating. Peak stall torque reaches 3.5 N.m across the 115...480 V three-phase envelope, against a continuous stall torque of 1.05 N.m at 1.7 A — roughly a 3.3× overload margin the drive has to deliver without tripping.
Speed-torque envelope across the supply rails
Nominal speed shifts with the bus: 4000 rpm at 230 V single phase, 8000 rpm at 400 V three-phase, and 9000 rpm at 480 V three-phase — the same motor frame, three different operating points, and the drive sizing has to match the bus the cabinet actually feeds. Nominal torque holds at 1.1 N.m on 230 V single phase but drops to 0.81 N.m on both 400 V and 480 V three-phase — the 230 V single-phase point is the torque sweet spot; the three-phase rails trade torque for top-end speed. Maximum mechanical speed is 9000 rpm — that is the hard ceiling on the shaft regardless of which bus the drive commands, and it sets the reducer ratio if the line needs more than that. Maximum current Irms and the 3-second peak output current are both 6.5 A — the drive's peak current limit has to be set at or above this figure to ride through stepper-style acceleration transients without the I²t foldback chopping in.
Encoder, cooling, and the sealed envelope
The Hiperface DSL absolute multiturn encoder rides on a single cable back to the drive — no separate battery box for multi-turn position retention, no second feedback cable to dress through the cable chain. Cooling is natural convection only — no integrated fan, no blower, and no dust path through the housing. Panel layout has to leave the motor's frame surface clear of adjacent heat sources, and IP65 on the motor body plus IP54 at the shaft bushing without a shaft seal ring means the wet-zone rating is on the housing, not the shaft exit. Shaft loading limits are 80 N axial and 710 N radial at 1000 rpm — for belt drives the radial figure derates with rpm, and direct-coupled loads stay well inside both envelopes.
