Speed-torque map across supply voltages
The SH31002M12A1200: This motor's performance shifts dramatically with the supply you feed it. On 400 V three-phase, it delivers 5.28 Nm nominal torque at 2000 rpm and 1090 W output power; feed it 480 V three-phase and the same torque holds at 2400 rpm for 1280 W. Drop to 230 V single-phase and nominal torque drops to 5.5 Nm at 1000 rpm, 580 W. On 115 V single-phase, you get 5.62 Nm at 500 rpm, 300 W. The peak stall torque is 18.3 Nm across the 115-480 V three-phase range — that's your short-term overload ceiling for acceleration or emergency stop. The continuous stall torque sits at 5.8 Nm across the three-phase range, pulled at 2.5 A continuous stall current. The torque constant is 2.32 Nm/A at 120 °C copper temperature — use that for drive current-loop tuning.
Encoder feedback and wiring
The encoder is an absolute multiturn SinCos Hiperface type — that's a single-cable feedback protocol common on Lexium drives. No separate battery backup needed for multiturn position retention. The electrical connection comes as either a rotatable right-angled connector or a straight connector; both are field-swappable for cable exit direction. Stator resistance is 8.6 Ω, inductance 24.3 mH — these are the parameters the drive's auto-tune routine needs for current-loop gains. Maximum RMS current is 9.0 A, with a 3-second peak of the same value.
Environmental sealing and mechanical limits
IP65 on the motor body and shaft bushing, IP67 on the housing — this motor handles washdown without a cover. Cooling is natural convection, so no fan to clog or fail. The 100 mm international standard flange (3.9 in) with a 95 mm centring collar and 9 mm mounting holes bolts straight onto standard NEMA or IEC mounts. Maximum radial force at the shaft nose drops with speed: 990 N at 1000 rpm, 690 N at 3000 rpm. Maximum axial force is 160 N. The shaft is 19 mm diameter with a 40 mm parallel keyed end — standard for direct coupling to a load without a gearbox.
