0.75 N·m nominal, 2.5 N·m peak — the working envelope
The Schneider SH30552P1AF4000 is a 55 mm flange servo in the SH3 family, carrying 0.75 N·m nominal torque at 230 V single-phase and 0.63 N·m on 400 V or 480 V three-phase, with peak stall torque of 2.5 N·m across the 115–480 V range — roughly 3.3× the nominal, which is the headroom sizing engineers budget for acceleration and deceleration steps in a pick-and-place or indexing cycle. Nominal speed climbs with the supply rail: 4000 rpm at 230 V single-phase, 8000 rpm at 400 V, and 9000 rpm at 480 V.
Mechanical fit — 55 mm flange, parallel key, IP65 motor body
The motor mounts on an international-standard 55 mm flange with a 40 mm centring collar and four 5.5 mm mounting holes, and the shaft is 9 mm diameter × 20 mm long with a 3 mm parallel key — the same key/shaft geometry the SH3 family uses across this frame size, so gearbox and coupling selection stays inside one catalogue section. The body carries IP65 on the motor housing with IP54 at the shaft bushing when no shaft seal ring is fitted (per IEC 60034-5), which keeps the winding safe from coolant splash and washdown but does not make the front shaft a fully sealed through-bore — a seal ring is the usual upgrade for wet end-of-arm or food-grade cells.
Encoder, brake and the wiring side
Feedback is an absolute single-turn Hiperface DSL encoder, and the power/brake signal rides through a quick-lock rotatable right-angle connector — the rotatable head matters in a crowded cabinet because it lets the cable exit in any of four directions without forcing a dedicated harness build. The integrated holding brake delivers 0.8 N·m of static torque at 10 W pull-in power, sized to hold the rotor (and its load) at standstill without overheating the coil during a long pause.
Sourcing reality
Quoted to order against the BOM line through independent distribution — confirm flange, brake option and encoder protocol against the BOM cell before committing, since the SH30552P1AF4000 suffix ties out the brake, encoder and connector geometry for this specific build.
