Motor ratings across supply configurations
The SH31401M01A2200 is a three-phase servo motor from Schneider Electric's SH3 series, delivering 1700 W continuous power. Its nominal speed and torque depend on the supply voltage: 375 rpm at 115 V single-phase, 750 rpm at 230 V single-phase, 1500 rpm at 400 V three-phase, and 1800 rpm at 480 V three-phase. Nominal torque ranges from 11 Nm at 115 V single-phase down to 10.4 Nm at 480 V three-phase, with continuous stall torque rated at 11.1 Nm across the 115-480 V three-phase range. Peak stall torque reaches 27 Nm under the same three-phase conditions.
Position feedback and environmental sealing
The motor carries an absolute single-turn SinCos Hiperface encoder, giving the drive controller position feedback on power-up without a homing routine — critical for applications that must resume from the last known position after a power cycle. IP65 rating on the motor body and shaft bushing, plus IP67 on the housing per IEC 60034-5, means this motor withstands washdown and dust ingress on food, beverage, or packaging lines. The rotatable right-angled connector lets the cable exit point be oriented after installation, simplifying routing in tight cabinets.
Mechanical interface and shaft details
The motor mounts on an international standard flange with a 140 mm (5.5 in) flange size and a 130 mm centring collar. The shaft is 24 mm diameter, 50 mm long, smooth (no keyway), with an 8 mm key width — confirm the coupling or pulley bore matches a smooth shaft before ordering.
Electrical parameters and thermal limits
Stator resistance is 5.3 Ω and inductance is 88.55 mH. The torque constant is 2.78 Nm/A at 120 °C copper temperature, and the back-EMF constant is 193 V/krpm at 20 °C. Continuous stall current is 4 A, with a maximum RMS current of 10.8 A. The motor is cooled by natural convection — no external fan, so the thermal budget depends on the mounting surface and ambient airflow. The hot-spot copper temperature limit is 130 °C.
