Torque and speed profile across supply voltages
The SH31401P01F1200: Nominal speed varies with the supply: 750 rpm on 115 V single phase, 1500 rpm on 230 V single phase, 3000 rpm on 400 V three phase, and 3600 rpm on 480 V three phase. The maximum mechanical speed is 4000 rpm. Nominal torque also shifts by voltage: 10.95 N·m at 115 V single phase, 10.6 N·m at 230 V single phase, 9.2 N·m at 400 V three phase, and 8.4 N·m at 480 V three phase. Continuous stall torque is 11.1 N·m across the 115–480 V three-phase range. Peak stall torque reaches 27 N·m (115–480 V three phase), and the holding brake delivers 23 N·m — enough to hold the load on a vertical axis without power.
Encoder, feedback, and environmental sealing
The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing cycle on power-up — the drive reads the absolute position from the encoder's multi-turn count. IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5 — the motor withstands washdown and wet environments. The straight electrical connector mates with a standard cable gland.
Mechanical interface and mounting
International standard flange, 140 mm (5.5 in) flange size, with a centring collar diameter of 130 mm (5.1 in) and depth of 3.5 mm (0.1 in). Mounting holes are 11 mm (0.4 in) diameter. Smooth shaft, 24 mm (0.9 in) diameter, 50 mm (2.0 in) shaft length. Maximum radial force is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm. Maximum axial force is 300 N.
Electrical parameters and thermal limits
Continuous power is 2900 W; nominal output power ranges from 860 W (115 V single phase) to 3170 W (480 V three phase). Continuous stall current is 7.8 A, maximum RMS current is 20.8 A. Natural convection cooling — no external fan. The motor relies on its own surface area and the machine's airflow for heat dissipation.
