The SH31401M01F2100 is a 140 mm flange-size servo motor from the SH3 family, with a smooth 24 mm shaft, 50 mm shaft length, and an overall body length of 255.5 mm. The IP65 rating on both the motor body and the shaft bushing means the unit withstands washdown and particulate ingress in food, packaging, or woodworking environments — the seal is certified to IEC 60034-5. The absolute single-turn SinCos Hiperface encoder eliminates the need for a homing sequence on power-up — the axis position is known immediately. This matters for applications where a reference move at start-up would collide with tooling or waste product. The encoder feedback is compatible with Schneider's Lexium drives that support the Hiperface protocol.
Speed and torque across the supply voltage range
Nominal speed varies with the supply: 375 rpm on 115 V single-phase, 750 rpm on 230 V single-phase, 1500 rpm on 400 V three-phase, and 1800 rpm on 480 V three-phase. The maximum mechanical speed is 4000 rpm, so the motor can be over-sped on the higher-voltage supplies if the drive and load permit. Nominal torque also depends on the supply: 11 N·m at 115 V single-phase, 10.95 N·m at 230 V single-phase, 10.6 N·m at 400 V three-phase, and 10.4 N·m at 480 V three-phase. Continuous stall torque is 11.1 N·m across the 115–480 V three-phase range, with a continuous stall current of 4 A. Peak stall torque reaches 27 N·m, and the maximum current Irms is 10.8 A — this is the current the drive must be sized to deliver during acceleration or overload events. The torque constant is 2.78 N·m/A at 120 °C copper temperature, and the back-EMF constant is 193 V/krpm at 20 °C. These values let the drive calculate the motor's electrical behaviour for tuning and current-loop gain settings.
Holding brake and mechanical limits
The integrated holding brake delivers 23 N·m of holding torque — enough to hold a vertical axis or a load with significant overhang without the drive having to maintain a torque loop at standstill. The brake is spring-applied, power-released; confirm the drive's brake control output can supply the coil current before wiring. Maximum axial force Fa is 300 N, and maximum radial force Fr is 1930 N at 1000 rpm, 1530 N at 2000 rpm, and 1340 N at 3000 rpm. These limits govern the coupling and belt-drive selection — exceeding them shortens bearing life or causes shaft deflection.
Sourcing and compliance documentation
The motor carries an IP65 rating per IEC 60034-5, which is a declared conformity for ingress protection. For RoHS, REACH, and UL documentation, the Schneider Electric declaration of conformity for the SH3 series applies — request the specific declaration for the SH31401M01F2100 order code at RFQ to satisfy a supplier-quality audit.
