690 W SH3 servo with Hiperface DSL feedback
The Schneider Electric SH30701P0AA3100 is a 690 W SH3-series servo motor delivering 1.4 N.m nominal torque at 3000 rpm on three-phase 400 V supply, with a peak stall torque of 3.5 N.m across the 115...480 V three-phase range. It carries an absolute single-turn Hiperface DSL encoder — a digital feedback protocol that transmits position and temperature data over a single cable pair, reducing wiring complexity compared to incremental or multi-cable resolver systems.
Speed and torque across supply voltages
Nominal speed is 3000 rpm on 230 V single-phase, 6000 rpm on 400 V three-phase, and 7200 rpm on 480 V three-phase — the motor's maximum mechanical speed is 8000 rpm, so the 480 V case runs close to the mechanical limit. Nominal torque drops from 1.4 N.m at 230 V single-phase to 1.1 N.m at both 400 V and 480 V three-phase — the torque constant is 0.69 N.m/A at 120 °C copper temperature, so the lower torque at higher voltage reflects the drive's current limit, not the motor's magnetic capability. Continuous stall torque is 1.25 N.m across the 115...480 V three-phase range at a continuous stall current of 1.8 A, while the maximum RMS current is 5.7 A — the headroom between stall and peak current supports short-duration acceleration or overload cycles.
Mounting, sealing, and connection
The motor uses an international standard flange with a 70 mm flange size and 60 mm centring collar — the 11 mm smooth shaft (no keyway) suits direct coupling to a load via a flexible jaw or bellows coupling, where the clamping hub transmits torque without a key. Electrical connection options include a rotatable right-angled connector and a quicklock straight connector — both are plug-in types that simplify motor swap-out without rewiring the cable gland, saving commissioning time on a multi-axis line.
