Voltage-dependent speed and torque — the supply dictates the performance
The SH30703P1BA3100: This SH3 servo motor delivers 3000 rpm nominal at 230 V single-phase, 6000 rpm at 400 V three-phase, and 7200 rpm at 480 V three-phase. The nominal torque shifts with the supply too: 2.8 N.m at 230 V single-phase, dropping to 2.1 N.m at 400 V or 480 V three-phase. The continuous power follows the same pattern — 830 W on single-phase, 1330 W on three-phase. If the line voltage at the cabinet is 400 V three-phase, the motor is a 6000 rpm / 1330 W machine; if the site only has 230 V single-phase, it is a 3000 rpm / 830 W machine. That is the first decision point for the BOM. The peak stall torque is 11.3 N.m across the 115-480 V three-phase range, giving a short-term overload ratio of about 5.4× the continuous torque — enough for aggressive acceleration profiles in indexing or pick-and-place. The continuous stall current is 4.1 A, and the maximum RMS current is 17 A, so the drive must be sized to deliver that peak without tripping.
Encoder and feedback — single-cable absolute multiturn
The encoder is an absolute multiturn Hiperface DSL type. That means position is known at power-up without a homing move, and the feedback runs over the motor power cable — no separate encoder cable needed. The electrical connection is a quicklock straight connector, so the cable assembly snaps in without tools. For the commissioning engineer, this simplifies the cable tray: one hybrid cable per axis instead of two.
IP65 and mechanical interface — washdown-ready, standard flange
Both the motor body and the shaft bushing are rated IP65 per IEC 60034-5. That means the motor withstands hose-down cleaning — suitable for food-and-beverage lines, washdown stations, or outdoor installations where the motor is not under a canopy. The flange size is 70 mm with a 60 mm centring collar and 2.5 mm collar depth. The shaft is 14 mm diameter with a parallel key, 30 mm shaft length. The mounting holes are 5.5 mm diameter on the flange. These dimensions match the standard IEC 72-1 flange pattern, so the motor bolts onto most gearboxes and linear actuators without an adapter plate.
