100 mm flange, 307.5 mm body — envelope fit for a 2.5 kW axis
The SH31004P11F2100 is a three-phase servo motor from the SH3 series, delivering 2500 W continuous power through a 100 mm IEC flange. The overall body length is 307.5 mm, with a 24 mm shaft extending 50 mm and an 8 mm parallel keyway — confirm the mating load-side coupling and bell-housing depth against these dimensions before committing the BOM line.
Speed-torque envelope — 750 to 3600 rpm, 40.5 N.m peak
Nominal speed depends on supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, 3600 rpm at 480 V three-phase. Nominal torque follows the same curve — 9.9 N.m at 115 V single-phase, dropping to 6.9 N.m at 480 V three-phase. Peak stall torque reaches 40.5 N.m across the 115–480 V three-phase range, which sets the acceleration limit for short-duration moves. Continuous stall torque is 10 N.m over the same voltage range — this is the thermal limit for holding at zero speed.
Absolute SinCos Hiperface encoder — no homing cycle needed
Feedback is an absolute single-turn SinCos Hiperface encoder. Single-turn means position is known within one revolution after power-up — no reference run required for rotary indexing. The SinCos analog track provides fine interpolation beyond the digital resolution; the Hiperface protocol carries both position and temperature data on the same pair of wires. This encoder type is compatible with Schneider's Lexium 28, 32, and some third-party drives that support the Hiperface interface.
IP65 — washdown-ready for wet or dusty environments
Both the motor body and shaft bushing carry IP65 protection per IEC 60034-5. The straight connector (rotatable right-angled variant available) seals against ingress, so the motor can be deployed in food-and-beverage washdown zones, outdoor conveyor lines, or machining coolant splash areas without a secondary cover. Cooling is by natural convection — no fan, so no forced-air path that could pull contaminants in.
Electrical parameters — stator resistance, inductance, torque constant
Stator resistance is 1.81 Ω, stator inductance 6.5 mH. The torque constant is 1.62 N.m/A at 120 °C copper temperature — derate the continuous current limit (maximum 32.3 A rms) by this figure to estimate available torque at thermal steady state. Back EMF constant is 103 V/krpm at 20 °C; at higher speeds the drive's DC bus voltage must exceed the back EMF plus resistive drop to maintain current control. The 3-second peak current matches the maximum rms current at 32.3 A — the drive's peak current capability must at least match this to achieve the 40.5 N.m peak stall torque.
