What this SH3 servo motor delivers
The SH31002P0AA4100 is a three-phase SH3 series servo motor from Schneider Electric, rated for 1930 W continuous power at 400 V or 480 V three-phase supply (1090 W on 230 V single-phase). Nominal torque runs 5.2 Nm at 400 V three-phase, derating to 4.6 Nm at 400 V and 4.4 Nm at 480 V — the torque curve shifts with the voltage you feed it. Peak stall torque hits 18.3 Nm across the 115...480 V three-phase range, so it handles short-duration overloads for high-inertia starts or rapid acceleration cycles.
Encoder and feedback — Hiperface DSL single-turn
Fitted with an absolute single-turn Hiperface DSL encoder, the motor reports position on power-up without a home cycle — the drive knows where the shaft is the moment the bus wakes up. Single-turn means the absolute position wraps every revolution; for multi-turn applications you need a different encoder variant or a drive that tracks turns externally.
Speed range by supply voltage
Nominal speed depends on the input voltage: 2000 rpm on 230 V single-phase, 4000 rpm on 400 V three-phase, and 4800 rpm on 480 V three-phase — the winding is wound for high-speed at higher line voltages.
IP65 — washdown-ready, but check the shaft bushing
Both the motor body and the shaft bushing carry IP65 per IEC 60034-5, so the motor survives hose-down cleaning in food or wet processing lines — the seal at the shaft exit is the same rating as the housing. The smooth shaft (19 mm diameter, 40 mm length) with an international standard flange (100 mm, centring collar 95 mm) mounts directly to standard gearboxes and couplings — no keyway, so torque transmission relies on a clamping or shrink-fit connection.
Electrical connections and compliance
The rotatable right-angled connector with QuickLock termination lets you orient the cable exit in tight panels — the connector rotates before locking, so the cable dress doesn't fight the gland plate. Stator resistance is 2.4 Ω and inductance is 6.75 mH at 20 °C — these numbers matter for tuning the current loop in the drive; the back EMF constant is 77 V/krpm at 20 °C.
