Speed-torque envelope across supply voltages
The SH31004P11F1100: This motor delivers 9.9 Nm nominal torque at 750 rpm on 115 V single-phase, 9.5 Nm at 1500 rpm on 230 V single-phase, 7.9 Nm at 3000 rpm on 400 V three-phase, and 6.9 Nm at 3600 rpm on 480 V three-phase — the speed ceiling and torque density shift with the supply, so the drive and line voltage must match the target duty point. Continuous power is 2500 W, with nominal output power ranging from 780 W on 115 V single-phase up to 2600 W on 480 V three-phase — the motor is wound for the higher voltage range; single-phase operation derates both torque and power significantly. Peak stall torque reaches 40.5 Nm across the 115–480 V three-phase range, backed by a 32.3 A peak current capability — this is the figure for acceleration and emergency stop sizing, not continuous duty.
Holding brake and mechanical interface
The integrated holding brake delivers 12 Nm holding torque — sufficient to hold a vertical load at rest without power to the motor windings, but the brake is not rated for dynamic stopping; the drive handles deceleration. Mounting uses a 100 mm international standard flange with a 9.0 mm bolt circle and 3.5 mm centring collar depth — the shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width.
Feedback, cooling, and environmental sealing
Feedback is an absolute single-turn SinCos Hiperface encoder — no homing sequence needed on power-up for single-turn applications; the absolute position is known immediately, which simplifies commissioning and recovery after a power loss. Cooling is natural convection — no fan, so the thermal budget depends entirely on the mounting surface and ambient airflow; the copper hot-spot temperature is rated at 130 °C, and the torque constant is specified at 120 °C winding temperature.
Electrical parameters for drive tuning
Stator resistance is 1.81 Ω and inductance is 18.35 mH — these set the electrical time constant and influence the current-loop tuning gains in the servo drive; the back EMF constant is 103 V/krpm at 20 °C, which determines the voltage required at a given speed. Maximum continuous current is 32.3 A rms — the drive must be sized to supply this current continuously at the target torque; the 4-pole construction gives a base speed range suited to the 3000–3600 rpm nominal speeds on three-phase supply. Radial force limits are 1070 N at 1000 rpm, 850 N at 2000 rpm, and 740 N at 3000 rpm; maximum axial force is 160 N — these constrain the belt tension or direct-coupling overhung load the shaft bearings can sustain.
Sourcing and lifecycle — current production, quoted to order
The sizing reference is SH31004P — this is the family base code; the full order code SH31004P11F1100 specifies the connector variant (rotatable right-angled or straight connector), encoder type, and brake option.
