Speed and torque — the voltage tradeoff
The SH31001P0AF4000: Nominal speed jumps from 2500 rpm on 230 V single-phase to 5000 rpm on 400 V three-phase, and hits 6000 rpm on 480 V three-phase. That's a 2.4× speed swing depending on what supply you've got in the cabinet. Nominal torque drops from 2.64 N·m at 230 V single-phase to 2.27 N·m on either 400 V or 480 V three-phase — the motor leans harder on torque at the lower voltage because it's running fewer poles effectively. If your application needs the full 2.64 N·m, you're locked to a 230 V single-phase feed.
Holding brake and encoder — what you're getting
The holding brake delivers 9 N·m (79.7 lbf·in) — enough to hold a vertical axis load at rest without servo current. Pull-in power is 12 W, so the brake coil won't cook the motor windings on a long idle. The encoder is an absolute single-turn Hiperface DSL — one cable for power and feedback, no separate battery backup needed for position retention across a power cycle. Smooth shaft, 19 mm diameter, 40 mm shaft length, with a centring collar depth of 3.5 mm. That shaft end means you're using a clamping hub, not a keyway.
IP65 body, but watch the shaft bushing
The motor body is IP65 per IEC 60034-5 — fine for washdown zones and dusty environments. The shaft bushing without a shaft seal ring drops to IP54. If your line sees direct spray at the shaft exit, add an external seal or specify the shaft seal ring option. Cooling is natural convection — no fan, so the 1190 W continuous power rating assumes free air around the flange. Mounting is an international standard flange, 100 mm square, with 9 mm mounting holes on a 4-hole pattern.
