Speed-torque envelope across supply voltages
The SH31001M01A1200: This SH3 frame servo delivers 3000 rpm at 400 V three-phase and 2500 rpm at 480 V three-phase, with nominal torque holding at 2.52 Nm across both three-phase voltages. On single-phase supply, speed drops to 1250 rpm at 230 V and 625 rpm at 115 V, with torque rising to 2.71 Nm and 2.8 Nm respectively — the motor is wound to trade speed for torque at lower bus voltages. Peak stall torque reaches 9.6 Nm across the 115-480 V three-phase range, and continuous stall torque is 2.94 Nm at 1.8 A continuous stall current — the thermal limit is set by natural convection cooling, so duty cycle matters in a continuous-torque application.
Encoder and feedback — absolute single-turn Hiperface
The absolute single-turn SinCos Hiperface encoder eliminates the need for a homing sequence on power-up — the rotor position is known immediately, which cuts cycle time on machines that power-cycle between batches. The SinCos analog track also gives interpolated position for velocity ripple below one encoder count. The rotatable right-angle connector and straight connector options let the cable exit point be oriented after the motor is flange-mounted — useful when the cable tray approach changes during panel layout.
Environmental sealing and mechanical interface
IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5 — the motor withstands washdown and hose-directed water, but the connector must be mated with the matching IP-rated cable assembly to maintain the seal at the electrical interface. The 100 mm flange (3.9 in) with a 95 mm centring collar and 3.5 mm collar depth mounts to the international standard flange pattern. Maximum radial force is 900 N at 1000 rpm, derating to 530 N at 5000 rpm — bearing life at high speed depends on the belt tension or coupling misalignment staying within this curve.
No official successor or pin-compatible alternative is listed — the SH31001M sizing reference indicates this is the base variant without holding brake, so a brake-equipped sibling would be a different order code with a longer body.
