Motor ratings across supply voltages
The SH31001M12F1000: This SH3 frame servo motor delivers nominal speeds that depend on the supply: 625 rpm at 115 V single-phase, 1250 rpm at 230 V single-phase, 2500 rpm at 400 V three-phase, and 3000 rpm at 480 V three-phase. The nominal output power scales similarly — 210 W at 115 V single-phase up to 930 W at 480 V three-phase. Continuous power is rated 660 W. Peak stall torque reaches 9.6 N.m across the 115–480 V three-phase range, with continuous stall torque at 2.94 N.m. The torque constant is 1.63 N.m/A at 120 °C copper temperature.
Encoder and feedback — absolute multiturn Hiperface
The motor carries an absolute multiturn SinCos Hiperface encoder. This gives position feedback on power-up without a homing cycle — useful for applications where the axis position must be known immediately after a power loss or controlled stop.
Holding brake and mechanical interface
An integrated holding brake holds 9 N.m (79.7 lbf.in). The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and 6 mm key width. Motor flange size is 100 mm (3.9 in) with a 95 mm centring collar and 3.5 mm collar depth.
Environmental protection and cooling
Protection rating is IP54 at the shaft bushing without a shaft seal ring, and IP65 for the motor body and shaft bushing with the seal ring fitted, per IEC 60034-5. Cooling is by natural convection — no external fan. The motor has 4 poles.
