Motor specs and what they mean for the build
The SH31002P1AF3000 is a three-phase servo motor from the SH3 series, fitted with a holding brake — the brake pull-in power is 12 W and holding torque is 9 N·m, enough to hold a vertical axis load at rest without the drive holding current. Nominal torque depends on the supply: 5.2 N·m at 230 V single-phase, 4.6 N·m at 400 V three-phase, and 4.4 N·m at 480 V three-phase. Peak stall torque reaches 18.3 N·m across the 115–480 V three-phase range, so the motor can deliver short bursts for acceleration or overcoming static friction. Continuous power is 1930 W at 400 V and 480 V three-phase; at 230 V single-phase it drops to 1090 W. The nominal speed varies with voltage too — 2000 rpm at 230 V single-phase, 4000 rpm at 400 V three-phase, and 4800 rpm at 480 V three-phase. The absolute single-turn Hiperface DSL encoder gives position feedback on power-up without a homing cycle — the drive knows the rotor angle immediately. This matters for applications where the machine must resume from the last known position after a power cycle.
Mounting, cooling, and environmental fit
Mounts on an international standard flange with a 100 mm flange size and a 95 mm centring collar. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length — standard for coupling to a gearbox or direct load. Cooling is natural convection — no fan, so the motor relies on air movement around the housing. The IP65 rating on the motor body means it withstands washdown and dust ingress; the shaft bushing without a shaft seal ring drops to IP54, so a shaft seal is needed for high-pressure wash zones. Maximum radial force is 2240 N at 1000 rpm, dropping to 1550 N at 3000 rpm — the bearing load limit follows the speed. Axial force limit is 300 N. These set the coupling and belt-tension budget.
Electrical parameters for drive tuning and cabling
Stator resistance is 2.4 Ω and inductance is 13.5 mH — these set the electrical time constant and influence the current-loop tuning in the drive. The torque constant is 1.21 N·m/A at 120 °C copper temperature; the back EMF constant is 77 V/krpm at 20 °C. Electrical connection uses a rotatable right-angle connector and a quicklock straight connector — the cabling exits can be oriented to fit tight cable-tray routing. The motor has 4 poles.
The sizing reference is SH31002P, which groups this motor with compatible drives and cables in the Schneider Electric motion catalog. The package quantity is one unit.
