2.9 kW at 400 V — three-phase servo with absolute feedback
The SH31401P11A1200 is a three-phase servo motor from Schneider Electric's SH3 series, delivering 2.9 kW continuous power at 400 V three-phase supply. Nominal speed reaches 3000 rpm on that supply, with a maximum mechanical speed of 4000 rpm — the safe overspeed ceiling for the rotor assembly. Torque output is supply-dependent: at 400 V three-phase, nominal torque is 9.2 Nm, while peak stall torque hits 27 Nm across the 115–480 V three-phase range. The continuous stall torque sits at 11.1 Nm, drawn at 7.8 A continuous stall current. Feedback comes from an absolute single-turn SinCos Hiperface encoder — no need for a homing sequence on power-up, which simplifies commissioning on multi-axis lines where absolute position must be retained through a power cycle.
IP65/IP67 sealed housing, natural convection cooling
The motor carries IP65 on the body and shaft bushing, with IP67 on the housing per IEC 60034-5 — meaning it withstands hose-directed water and dust ingress. This suits washdown zones in food processing or outdoor conveyor sections where moisture is constant. Cooling is natural convection — no external fan or forced air required. In a confined cabinet or high-ambient installation, the thermal limit (130 °C copper hot-spot) will be reached sooner than with a fan-cooled equivalent; account for derating if the motor is enclosed. Electrical connection is via a straight connector, which simplifies cable routing in tight panels compared to a right-angle version. The flange is an international standard 140 mm size (5.5 in) with a 130 mm centring collar and 3.5 mm collar depth — a common interface for gearboxes and mounting brackets.
Shaft and mechanical interface for direct coupling
The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and an 8 mm key width — a standard metric keyway that mates with common couplings and pulleys. Maximum radial force at 1000 rpm is 1930 N, dropping to 1340 N at 3000 rpm; axial force limit is 300 N. These set the bearing life envelope for belt-driven or overhung loads. Stator resistance is 1.41 Ω and inductance 23.72 mH — these electrical parameters are needed for the drive's autotune routine and for thermal modeling of the winding at sustained overload.
No official successor or cross-reference exists for this order code — it is the current build. The sizing reference SH31401P identifies the frame; the suffix 11A1200 encodes the winding, encoder, and connector variant. For volume or project pricing, a quote request with the target quantity and delivery schedule is the standard path.
