The SH31003P12F2100 is a 2.4 kW continuous-power servo motor from Schneider Electric's SH3 family, built for three-phase supplies only — 400 V or 480 V three-phase input is required to reach the nominal output power of 2390 W or 2560 W respectively; single-phase 115 V or 230 V operation is possible but derates output to 790 W or 1470 W. The holding brake integrated into the motor delivers 9 N·m of holding torque, which means the motor can hold a vertical load at rest without a separate external brake resistor or mechanical lock. For axis sizing, the nominal torque varies by supply: 5.1 N·m at 480 V three-phase, 7.5 N·m at 115 V single-phase, 7 N·m at 230 V single-phase, and 5.7 N·m at 400 V three-phase — the torque constant is 1.22 N·m/A at 120 °C copper temperature, so the drive current limit must be set accordingly. Peak stall torque reaches 28.3 N·m across the 115...480 V three-phase range, with a 3-second peak current of 28.3 A — this transient overload capability handles acceleration or emergency stop events without tripping, provided the drive can supply the peak current.
Encoder, cooling, and environmental sealing — integration constraints
The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — this saves cycle time in multi-axis machines where homing would otherwise add seconds per station. Cooling is by natural convection only — no integrated fan means the motor relies on the machine frame or ambient air movement for heat dissipation; the copper hot-spot temperature limit is 130 °C, and the continuous stall torque of 8 N·m (115...480 V three-phase) is the thermal limit at zero speed. IP65 rating on both the motor body and the shaft bushing (per IEC 60034-5) means the motor withstands hose-down cleaning and moderate dust ingress — suitable for food processing or washdown environments, but the connector interface (straight or rotatable right-angle) must be mated with an IP65-rated cable to maintain the seal. Maximum radial force at the shaft is 1050 N at 1000 rpm, dropping to 660 N at 4000 rpm — this governs the allowable belt tension or direct-coupling misalignment before bearing life is compromised.
Mechanical envelope — flange, shaft, mounting
The 100 mm international standard flange with a 3.5 mm centring collar depth and 9.0 mm mounting holes bolts directly to standard NEMA or IEC motor mounts — no adapter plate needed for most common servo brackets. Shaft is 19 mm diameter with a 6 mm parallel key, 40 mm shaft length — this accepts standard couplings for 19 mm bores; the parallel key end transmits torque without a clamping hub, though a keyed coupling is required. Overall length is 271.5 mm — measure the available cavity before ordering; the straight or right-angle connector adds axial or radial clearance depending on the configuration chosen.
Electrical parameters for drive tuning and voltage budget
Stator resistance is 1.43 Ω and stator inductance is 4.7 mH — these set the current-loop bandwidth and the resistive losses (I²R) at full load; the back EMF constant is 77 V/krpm at 20 °C, meaning at 4000 rpm the motor generates 308 V line-to-line, leaving headroom for a 480 V drive bus. 4-pole construction gives a base speed of 4000 rpm at 400 V three-phase, with nominal speeds also listed at 1000 rpm (115 V single-phase), 2000 rpm (230 V single-phase), and 4800 rpm (480 V three-phase) — the drive must be programmed for the correct pole count and voltage-dependent speed curve.
