Three-phase servo with integrated brake — 1130 W continuous, 3000 rpm baseline
The SH30702P0AF3100 is a Schneider Electric SH3 series servo motor delivering 1130 W continuous output power at 400 V or 480 V three-phase supply, with a nominal speed of 3000 rpm under those conditions. At 230 V single-phase input, output drops to 610 W and the speed ceiling is 3000 rpm — the full 7200 rpm is only available on 480 V three-phase. It carries an integrated holding brake rated at 3 N·m holding torque and 7 W pull-in power, so the motor holds position on a vertical axis when power is removed — no external brake resistor or mechanical lock needed for the hold function.
The absolute single-turn Hiperface DSL encoder provides position feedback over a digital serial link without a separate battery backup for multi-turn counts — the single-turn resolution is sufficient for applications that home on power-up or use a mechanical reference. The DSL protocol is common on Lexium 32 and 28 drives, so the motor pairs directly without an external feedback converter. The rotatable right-angled connector and quicklock straight connector let the cable exit in two orientations, simplifying routing in tight enclosures.
Torque profile and thermal limits
Continuous stall torque is 2.04 N·m across the 115–480 V three-phase range, with a continuous stall current of 2.9 A. Peak stall torque reaches 7.6 N·m — roughly 3.7× the continuous rating — for short acceleration bursts or breakaway loads. The torque constant is 0.7 N·m/A at 120 °C copper temperature, so the drive's current loop directly scales torque output. Natural convection cooling means no external fan or coolant lines — the motor sheds heat through its flange and housing. The stator resistance is 4.2 Ω and inductance 21.3 mH, giving an electrical time constant around 5 ms that the drive's current regulator must handle. Maximum axial force is 160 N, radial force 990 N at 1000 rpm — the shaft bearings are sized for direct coupling without a separate bearing support on moderate loads.
