Motor ratings that depend on the line voltage
The SH31401P0AA4000 delivers different torque and power depending on the supply voltage it sees. At 230 V single-phase, nominal speed is 1500 rpm with 10.6 N.m nominal torque and 1670 W output. Feed it 400 V three-phase and those numbers shift to 3000 rpm, 9.2 N.m, and 2890 W. At 480 V three-phase, it runs 3600 rpm, 8.4 N.m, and 2890 W. Continuous stall torque sits at 11.1 N.m across the 115...480 V three-phase range, with a peak stall torque of 27 N.m for short-term overloads. The continuous stall current is 7.8 A; maximum current Irms is 20.8 A — use the higher figure for drive sizing during acceleration and deceleration phases.
Feedback, wiring, and environmental sealing
The encoder is an absolute single-turn Hiperface DSL type with 262144 points per turn resolution — no homing sequence needed on power-up for single-turn applications. The back EMF constant is 100 V/krpm at 20°C, and the torque constant is 1.43 N.m/A at 120°C copper temperature. Electrical connection is via a Quicklock rotatable right-angle connector — the connector body rotates for cable exit orientation without breaking the seal. The motor body is IP65 per IEC 60034-5; the shaft bushing without a shaft seal ring drops to IP54. If the application sees directed spray at the shaft exit, plan for an external shaft seal. Cooling is natural convection — no external fan. The continuous power rating of 2900 W assumes free airflow around the motor body; derate if mounted in a confined space or near heat sources. Stator resistance is 1.41 Ohm and inductance is 16.3 mH, which the drive's current loop tuning will need.
Mechanical fit — flange, shaft, and mounting pattern
The motor flange size is 140 mm (IEC standard), with a centring collar diameter of 130 mm and depth of 3.5 mm. Four mounting holes on a 165 mm bolt circle, each 11 mm diameter — M10 or 3/8-inch bolts fit. Overall length is 217.5 mm. The shaft is 24 mm diameter, 50 mm long, with a smooth shaft end — no keyway. This means the load coupling must use a clamping or friction-based method (taper-lock bushing, shrink disc, or set-screw hub with a split bore). No brake is fitted, so vertical-axis loads require an external holding brake or a motor variant with the brake option.
