Motor sizing and torque delivery across supply voltages
The SH31002P1BF3100 delivers 1930 W continuous power at 400 V or 480 V three-phase, with nominal torque dropping from 5.2 N.m at 230 V single-phase to 4.6 N.m at 400 V and 4.4 N.m at 480 V three-phase — the torque curve shifts with the available bus voltage, so the drive supply determines the usable load. Peak stall torque reaches 18.3 N.m across the 115–480 V three-phase range, giving a 3.5× overload margin over the 400 V nominal torque for acceleration and emergency stops. The built-in holding brake delivers 9 N.m static torque — enough to hold a vertical axis load at rest without the drive holding current, with a 12 W pull-in power that keeps the thermal budget low in a sealed cabinet.
Encoder feedback and environmental sealing for washdown zones
Absolute multiturn Hiperface DSL encoder eliminates the need for a home cycle on power-up — the rotor position is known immediately, which matters for pick-and-place or gantry axes where a reference move wastes cycle time. Electrical connection uses a rotatable right-angled connector plus a quicklock straight connector — the rotatable option lets the cable exit in the direction that fits the cable tray without an adapter.
Mechanical interface and bearing load limits
International standard flange with 100 mm square, 95 mm centring collar, and 9 mm mounting holes — bolts directly to the standard NEMA 100 frame pattern without an adapter plate. 19 mm shaft diameter with parallel key and 40 mm shaft length — the key transmits the peak torque without slipping, and the 6 mm key width matches standard key stock for field replacement. Maximum radial force is 3730 N at 1000 rpm, dropping to 2580 N at 3000 rpm — the bearing life at the higher speed limits the belt-tension or direct-couple load; stay under the curve for the operating speed. Maximum axial force is 740 N — relevant for helical-gear or leadscrew couplings that push or pull on the shaft; exceeding this loads the bearing axially and shortens life.
Electrical parameters and thermal limits for drive tuning
Torque constant is 1.21 N.m/A at 120 °C copper temperature, and back EMF constant is 77 V/krpm at 20 °C — the drive's velocity loop gain and the regeneration voltage at high speed depend on these values. Maximum RMS current is 17.1 A — the drive must be sized to supply this for peak torque; continuous current is lower and follows the nominal torque curve. Natural convection cooling with a 130 °C copper hot-spot limit — no fan means the motor relies on the machine's ambient airflow; in a still-air enclosure, derate the continuous torque or add forced ventilation.
