Speed and torque across the supply range
The SH30703P11F2200: This SH3 servo motor delivers nominal torque of 2.1 N.m at both 400 V and 480 V three-phase, with nominal output power reaching 1.55 kW at 480 V. On single-phase supplies the torque derates to 2.8 N.m at 230 V and 2.95 N.m at 115 V, while nominal speed shifts from 6000 rpm (three-phase) down to 1500 rpm on 115 V single-phase — a critical constraint when the install site lacks three-phase power. The continuous power rating of 1330 W and continuous stall torque of 2.94 N.m across the 115–480 V three-phase range define the thermal steady-state capability for sizing the driven load without exceeding the natural convection cooling limit.
Holding brake and encoder feedback
Feedback comes from an absolute single-turn SinCos Hiperface encoder — this gives position at power-on without a homing sequence, critical for applications that must resume from the last commanded position after a power cycle. The single-turn resolution limits absolute position tracking to one revolution; multi-turn applications need a different encoder variant.
Sealing and mechanical limits for the install environment
IP65 on the motor body and shaft bushing, plus IP67 on the housing per IEC 60034-5, means the motor withstands hose-down cleaning and occasional submersion — suitable for food-and-beverage washdown zones or outdoor installations where the motor is not fully sheltered. Maximum radial force at the shaft is 730 N at 1000 rpm, derating to 400 N at 6000 rpm — the bearing life calculation must use the force at the application's operating speed, not the static maximum. Axial force is capped at 80 N, so direct-drive loads with thrust (helical gears, leadscrews) need a separate thrust bearing.
Peak capability and electrical parameters
Peak stall torque reaches 11.3 N.m at 115–480 V three-phase, with a corresponding peak current of 17.0 A for 3 seconds — this is the acceleration/deceleration ceiling before the drive trips on overcurrent. The stator resistance of 2.7 Ohm and inductance of 20.3 mH set the electrical time constant and influence the drive's current-loop tuning. The torque constant of 0.72 N.m/A at 120 °C copper temperature means the drive must supply roughly 4.1 A to produce the continuous stall torque of 2.94 N.m at hot operating temperature — a useful figure for sizing the drive's continuous current rating.
Sourcing and lifecycle status
The motor uses an international standard flange with a 70 mm flange size and 14 mm shaft diameter with a parallel key — this matches the IEC mounting footprint common across SH3 series frames, so a replacement or spare can slot into the same mechanical interface without re-machining the mounting plate.
